What are VOCs?

VOCs are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Examples include:

  • Paints and lacquers
  • Paint strippers
  • Cleaning supplies
  • Pesticides
  • Building materials and furnishings
  • Office equipment such as copiers and printers
  • Correction fluids and carbonless copy paper
  • Graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions
  • Hobbies
  • Dry-cleaned clothing
  • Air fresheners
  • Personal care products
  • Disinfectants

Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.

AC Dehumidifier(Dry) Mode- What and When Do You Use It?

What is Dehumidifier (Dry) Mode in AC?

High Humidity is the number one cause of mildew and mold growth in the home.  It is also responsible for increased Allergy symptoms and can be a trigger for an Asthma attack.

Dehumidifier mode, also called Dry Mode,  on an AC is the setting that turns on the dehumidifying function of an air conditioner to reduce excess humidity in the air.

When there is too much humidity in the air, the temperature can seem hotter than what it actually is.
Using the dehumidifier/ dry mode on the AC will help reduce the moisture in the air and restore comfortability back to your home.

 

What is the function of dry mode in AC?

Dry mode in an AC functions like a dehumidifier. Dehumidifiers and air conditioners are actually very similar in the way they work. They both drag air across a set of cooling coils that causes the air to condense.

User Guidelines for AC Dehumidifier (Dry) Mode

Condition Dry Mode Usage Recommended Settings Notes
High Humidity, Mild Temperature Yes Moderate fan speed Ideal for reducing humidity without overcooling the room.
High Humidity, High Temperature Optional Combine with cool mode at a higher temperature setting Helps in maintaining comfort without excessive cooling.
Moderate Humidity, High Temperature No Use cool mode instead Dry mode is less effective and unnecessary.
Continuous High Humidity Yes, intermittently Use periodically to maintain comfort Prevents overuse and maintains energy efficiency.
Night Time or Low Activity Yes Lower fan speed, higher temperature Reduces noise and maintains comfort during less active hours.

AC Dehumidifier Dry ModeAir conditioner dry mode vs. dehumidifier

The difference is that air conditioners move the air across the cooling coils to cool off the air where is a dehumidifier moves the air across the cooling coils to condense the air but then reheats the air to repeat the process.

Dry mode vs. cool mode

Dry mode on your AC is the air conditioning setting that turns on the dehumidification function of the AC to reduce the humidity in the air.

Cool mode is the setting that cools down the air. Cool mode is the most common setting on an AC. It is the mood of the air conditioner that cools down the room to the temperature that you set the thermostat to.

Air conditioner dehumidifier mode

Humidity, especially the excessive humidity that tends to hit in the hottest months can be a real enemy to your air conditioning.

When the relative humidity gets to a certain level, you can feel like the air conditioner is not even on.

And usually what happens is that you run to turn the thermostat down cooler.

But with so much moisture in the air and adding more power to the air conditioner, the results of turning the air conditioner thermostat down usually leads to the unit freezing over.

Then there is no cool air coming from it at all.

Another reason that humidity threatens your AC unit is that your system has to run on overdrive to keep up with the extra demand that the humidity places on it.

But you may be sitting on an air conditioner that has a function to help in those situations. And you might not have even known it.

The function I’m talking about is the air conditioner dehumidifier mode.

The air conditioner dehumidifier mode is usually represented by a raindrop symbol on the thermostat. It is also called the dry mode if you have an air conditioner with this function but it does not say dehumidifier.

what is dry mode in ac

Does an air conditioner dehumidify?

When your AC is in dehumidifier mode,
It turns off the cooling function and slows down the fan so that the air conditioning functions as a dehumidifier to reduce the moisture in the air.

Does air conditioning dry out the air?

By reducing the moisture in the air, you can regain comfortability without even having the cool mode running.

Not only will that save you money on energy, it will help save you in the long run by not overworking your air conditioning system.

Best temperature for dry mode

The best temperature to use dry mode is when the humidity is excessive but the actual temperature is not that hot.

The ideal of turning the AC on dry mode is to reduce the moisture level in the air and restore the comfortability of the area without using the cool air mode of the AC.

The function of Dry mode on an AC is to lower the humidity in the room so that the air feels cooler. It does not actually control or utilize the thermostat to achieve a designated temperature.

Dry mode vs. Cool mode power consumption

ACs are one of the biggest energy hogs in your house. Everyone knows how much the utility bill can skyrocket in the summer months because of the power that an air conditioning system uses.

The different modes on an air conditioning unit or not only to help provide you with the most comfort possible in terms of climate control but also in financial terms.

The cool mode on an air conditioner is easily the most expensive to run. And it is the setting that most people tend to use exclusively.

But there are different times when using the cool mode on an air conditioner is not only more expensive, it can’t get the job done as well.

Dry mode on an air conditioner can actually lower your energy bill provided the climate dictates it.

When the humidity is so high that it is overcoming the air conditioning,

Turning the AC dry mode will not only help reduce the humidity in the air and make the air feel more comfortable, it will turn off certain features on the air conditioner that are causing the energy bill to be more expensive.

When the dry mode is functioning, it turns down the cool air and it slows the fan way down.

Which means the power consumption of the air conditioner is way down.

In other words, less power, more money in your pocket.

Not only does humidity cause your air conditioner I do feel like it’s doing less than an adequate job, it also makes your air conditioner overcompensate to try to get the temperature in the room down to a comfortable level.

That means the power consumption in cool mode during times of excessive humidity will actually cost you more.

Air conditioner dry mode in winter.

The dry mode on an air conditioner, though it works like a dehumidifier to a certain point.
But at the end of the day they do not have the full function of a dehumidifier.

A dehumidifier compared to a air conditioner not only condenses the water to capture the humidity, it reheats the air that is released.

An air conditioner simply does not have this capacity.

Even most dehumidifiers call for the temperature to be at least 60 degrees.
Which makes them obsolete during the winter.

Using an air conditioning as a dehumidifier during the winter will not work for that intention, it will most likely cause damage to your unit.air conditioner dehumidifier mode

Limitations and Considerations

While the dry mode in AC units can mitigate humidity to some extent, it may not match the efficacy of specialized devices like standalone dehumidifiers.

For instance, the Vellgoo Dehumidifier, acclaimed for its performance in large spaces, comes with user-friendly features such as a washable air filter and an automated pump for water drainage, offering a more tailored approach to humidity control.

Considering such a product could enhance moisture management, especially in highly humid environments, providing a more comprehensive solution than AC dry mode alone.

Why Central Heating Causes Dry Coughs and How to Prevent Them

Why is My Central Heat Making Me Cough?

If you find yourself coughing more often when the central heating is on, you’re not alone. Central heating can dry out the air and irritate respiratory passages, leading to coughing for some people. However, it’s not just the dry air that could be causing discomfort. Mold in HVAC systems can also contribute to respiratory issues, including coughing. Thankfully, there are steps you can take to mitigate these effects and keep your airways calm.

Why Central Heating Causes Dry Air

Central heating works by warming air and distributing it throughout your home via vents and ducts. However, this heated air lacks moisture. As it circulates, the dry air evaporates moisture from surfaces like your skin, nasal passages, throat, and lungs, which can make tissues dry, irritated, and inflamed, triggering coughing.

Colder outdoor air holds less moisture than warm indoor air. So when you heat up cold outdoor air, its relative humidity drops dramatically. Central heating systems also lack a humidification component to add moisture back into the air.

dirty ductThe Hidden Hazards of Dirty Ducts

 Dirty ducts can significantly compromise your indoor air quality and the efficiency of your HVAC system.
Accumulated dust, pollen, pet dander, and other pollutants in the ducts can circulate contaminated air throughout your home, exacerbating allergies, respiratory problems, and asthma symptoms. Moreover, this buildup can restrict airflow, forcing your system to work harder and leading to increased energy consumption and decreased system efficiency.2

Recognizing the signs of dirty ducts is key to maintaining a healthy indoor environment.
Indicators such as visible dust buildup around vents, unusual odors when the HVAC system is running, and an increase in respiratory issues or allergic reactions can signal the need for professional duct cleaning. Ensuring your ductwork is clean not only enhances air quality but also contributes to the overall efficiency and longevity of your HVAC system.1

Ventilation and Air Circulation

Before we delve into advanced air purification technologies like UV light solutions, it’s essential to understand the foundational role of ventilation and air circulation in maintaining indoor air quality. Proper ventilation is key to ensuring a healthy living environment, especially during the heating season when homes are sealed tight against the cold.

Why Ventilation Matters

Ventilation involves the exchange of indoor air with fresh outdoor air, which helps to reduce the accumulation of indoor air pollutants, including dust, allergens, and volatile organic compounds (VOCs). Good ventilation practices can also help mitigate the drying effect of central heating by introducing air with a higher moisture content from outside, particularly in areas with relatively humid outdoor climates.

Strategies for Improved Air Circulation

  • Natural Ventilation: Simply opening windows and doors for short periods can significantly improve air quality, even in cold weather. This allows stale, dry air to escape and fresh, moist air to enter.
  • Mechanical Ventilation: For homes in extreme climates or those with poor natural ventilation, mechanical systems such as Heat Recovery Ventilators (HRVs) or Energy Recovery Ventilators (ERVs) can provide controlled ventilation without significant heat loss.
  • Ceiling and Exhaust Fans: Utilizing ceiling fans can help circulate heated air more evenly throughout your home, reducing hot and cold spots and improving comfort. Exhaust fans, especially in kitchens and bathrooms, are crucial for removing excess moisture and odors and preventing mold growth.

The Role of Air Circulation

In addition to bringing in fresh air, ensuring that the air inside your home moves effectively can prevent the accumulation of airborne pollutants. Air circulation can be enhanced with strategic use of fans, ensuring that air filters are clean and unobstructed, and making sure that furniture does not block air vents.

hvac coughMold in HVAC Systems

In addition to drying out the air, central heating systems can harbor mold, which exacerbates respiratory issues. Mold thrives in moist environments, and when it grows in the ductwork or on other HVAC components, spores can spread throughout your home. Inhaling these spores can cause allergic reactions, exacerbate asthma, and provoke coughing.

Regular HVAC maintenance is crucial to prevent mold growth. This includes cleaning or replacing air filters, ensuring proper drainage, and inspecting ductwork for signs of moisture or mold. If mold is detected, professional cleaning may be necessary to remove it and prevent future growth.

It’s important to choose a location that will provide optimal coverage of the air flowing through the system.

3. Determine lamp type and quantity

The type and quantity of UV lamps needed will depend on the size of the HVAC system and the level of air disinfection required.

A qualified installer can help determine the appropriate lamp type and quantity.

4.Install the lamps correctly

Once the location and lamp type and quantity have been determined, the lamps can be installed.

UV lamps should be installed in a way that minimizes exposure to humans and pets, as direct exposure to UV radiation can be harmful.

Shielding and warning signs can be used to prevent accidental exposure.

5. Connect the power supply

After the lamps are installed, they need to be connected to the power supply.

This should be done by a qualified professional to ensure that the wiring is done safely and in compliance with local electrical codes.

6.Test the lamps

Once the lamps are installed and connected, they should be tested to ensure that they are functioning properly.

A professional installer can perform a test to verify that the lamps are emitting the correct amount of UV radiation.

Can I Put a Window Air Conditioner Work on the Floor? Why Not?

Will a window air conditioner work on the floor?

Technically, a window air conditioner can turn on and run while sitting on the floor. However, the way a window AC unit expels heat, drains condensation, and exchanges air can make using it on the floor less than ideal. These units are designed to be mounted in a window or through a wall to ensure proper ventilation, efficient cooling, and effective moisture drainage. Placing a window AC on the floor may lead to reduced efficiency, potential damage to the unit, and inadequate cooling performance.

Introduction

It’s not uncommon to find yourself in need of an air conditioner while being confined to an area where installing one isn’t exactly straightforward.

Various circumstances might lead you to occupy a room without windows, or perhaps you’re in a garage, workshop, or another type of space not originally designed to accommodate a window air conditioner.
In such situations, it’s tempting to consider using a spare window air conditioning unit you might have on hand. The question arises: Can this device simply be brought inside and placed on the floor or a table to cool the room?

Unfortunately, the design of window air conditioners doesn’t support effective cooling when the unit is not properly installed in a window.

These devices are specifically engineered to operate within a window frame, ensuring optimal air exchange, efficient cooling, and proper moisture drainage.

When placed in an unintended location, such as on the floor, their performance is significantly compromised, leading to inefficiency and potentially even damage to the unit.

In this article, we aim to elucidate the critical role of placement in maximizing the effectiveness of a window air conditioner. The concept of placing such a unit on the floor serves as an illustrative example to highlight how positioning impacts its functionality.

How does the placement of a window air conditioner effects how it will cool a room.

Heat Expulsion

Window air conditioners are designed to expel heat from their rear. If you’ve ever passed behind one, you’ve likely felt the warm air being emitted. Placing a window AC on the floor would result in it discharging cool air from the front but simultaneously releasing hot air from the back, effectively negating the cooling effect. The design intention behind these units is for them to be mounted in a window, allowing them to expel heat outside, not into the room.

Drainage

These units also work by extracting moisture from the air, condensing it, and then draining it through a hole at the bottom. This design is another reason why window ACs are intended for window installation, ensuring that the condensation exits the unit outside the house, preventing indoor water accumulation.

Hot Air Circulation

Considering that hot air rises and the coolest air in a room is near the floor, a window AC placed too low may recycle this cool air instead of drawing in and cooling the warmer air above. This could result in inefficient cooling, especially in the areas of the room where it’s most needed.

Noise Levels

The design of a window air conditioner also takes into account noise reduction, with the noisier components like the compressor and motor positioned to be outside the house when installed in a window. Placing the unit indoors would lead to increased noise levels, making the environment less comfortable.

Emergency Use

In emergency situations where no other cooling options are available, a window AC can technically be run on the floor. Direct exposure to the cool air can provide relief, albeit in a limited area. However, it’s important to manage the drainage by placing a pan underneath to collect water, and be prepared for increased indoor noise and potentially uneven cooling.

Ultimately, while a window air conditioner can function on the floor in specific scenarios, such placement is far from ideal and undermines the unit’s efficiency, design purpose, and overall effectiveness in cooling a room.

Can you put a window air conditioner on a table?

Placing a window air conditioner on a table does offer a slight improvement over having it on the floor, primarily because it would be positioned to draw in warmer air from the room rather than the cooler air found at floor level.

Even when elevated on a table, the air conditioner would still expel hot air from its rear. This expelled heat could warm other areas of the room, counteracting the cooling effect generated at the front of the unit. In a typical window installation, this heat is directed outside, away from the interior space.

Also the problem of condensation drainage persists. Window air conditioners are designed to allow condensation to drip outside when mounted in a window. When placed on a table, there would need to be an alternative method to collect or direct this water away, preventing damage to the table surface and avoiding water accumulation on the floor.

The operating noise, particularly from the compressor and motor, would be more pronounced when the unit is used inside the room instead of being partially outside a window.

DIY Engineering Solutions

Some people have creatively addressed these challenges by employing DIY methods, such as attaching ductwork to the rear of the unit to channel the expelled heat into an attic, closet, or another area where it won’t raise the room’s temperature. While this can be an effective workaround for the heat expulsion issue, it requires a certain level of technical skill and understanding of air conditioning systems to implement safely and effectively.

Considerations

If you’re in a situation without window access but have a window AC unit, exploring such DIY solutions might seem appealing. However, it’s crucial to address the drainage issue by finding a way to capture or direct the condensation effectively. Additionally, the increased noise level from having the unit operate entirely indoors is an important factor to consider for your comfort and the comfort of others in the space.

How Do You Cool a Room with No Windows?

Method Description Best For
Portable Air Conditioners Versatile units that require venting through ceiling, dryer vent, or wall. Need drainage for condensation. Flexible cooling, temporary setups
Evaporative Coolers Best for dry climates, use water evaporation to cool air. Add moisture, no external venting needed. Dry, low-humidity areas
Split Ductless Air Conditioners Consist of outdoor and indoor units, require professional installation. Quiet and efficient. Permanent, efficient cooling solution
Fans and Air Circulation Improve air movement without lowering temperature. Makes the room feel cooler by circulating air. Immediate airflow improvement
Thermal Curtains and Insulation Prevent heat from entering by using insulating materials on doors or adding wall insulation. Reducing heat gain from outside
Dehumidifiers Remove moisture from the air, making the room feel cooler in humid climates. Humid climates
Cool Roofing or Reflective Materials Use materials that reflect sunlight to reduce heat absorption in rooms at the top of buildings. Top-floor or attic rooms
Heat-Generating Appliance Management Reduce use of appliances that generate heat, especially during hot parts of the day. All areas, especially small, enclosed spaces
Creative Venting Solutions Use vents to circulate cool air from adjacent rooms or expel warm air to the outside. Rooms adjacent to cooled or ventilated spaces

Cooling a room without windows presents a unique challenge, as traditional window air conditioners are not an option. However, there are several alternative methods to cool such a space effectively:

1. Portable Air Conditioners

Portable air conditioners are a versatile solution. They don’t require window access for installation but do need a way to vent hot air outside. This can be achieved through a drop ceiling, dryer vent, or a hole in the wall. Ensure the unit has an appropriate drainage system for condensation.

2. Evaporative Coolers (Swamp Coolers)

Evaporative coolers are best suited for dry climates. They use the evaporation of water to cool the air, which can be an efficient method in areas with low humidity. No external venting is required, but they do add moisture to the air, which might be a consideration depending on the climate.

3. Split Ductless Air Conditioners (Mini-Split Systems)

Mini-split systems are an efficient way to cool rooms without windows. They consist of an outdoor compressor/condenser unit and one or more indoor air handling units, connected by a small conduit. Installation requires a professional but offers a permanent, quiet, and efficient cooling solution.

4. Fans and Air Circulation

Enhancing air circulation can also help cool a room. Ceiling fans or oscillating fans don’t lower the room temperature but can make it feel cooler by moving air around. Strategically placed fans can help circulate cool air from other parts of the building into the windowless room.

5. Thermal Curtains and Insulation

Improving the room’s insulation can prevent heat from entering. Using thermal curtains or blackout curtains on any doors leading to brighter, hotter areas can help keep the room cooler. Insulating any ductwork or adding insulation to walls can also reduce heat gain.

6. Dehumidifiers

In humid climates, a dehumidifier can make a room feel cooler by removing moisture from the air, even though it doesn’t lower the temperature. Less humidity means sweat evaporates more quickly, which naturally cools the body.

7. Cool Roofing or Reflective Materials

If the room is at the top of a building, using cool roofing materials or reflective paint can reduce heat absorption from the sun, keeping the space cooler.

8. Heat-Generating Appliance Management

Minimize the use of heat-generating appliances within the room during the hottest parts of the day. This includes computers, printers, and especially kitchen appliances if the space includes a cooking area.

9. Creative Venting Solutions

If there’s access to an adjacent room with windows or external walls, you can create a venting solution through the adjoining wall to help circulate cool air into the windowless space or expel warm air.

When choosing a cooling method, consider the room’s size, your budget, and the climate in your area. Some solutions may require professional installation, but they can provide a comfortable and sustainable environment in windowless rooms.

 

Do You Have to Use Distilled Water in a Humidifier? Really?

Do You Have to Use Distilled Water in a Humidifier?

“No. A humidifier will work with any type of water, distilled, tap, or otherwise, to add moisture back into the air. It’s a fact. But certain types of water, especially tap water,  because of the mineral and chemical content, will shorten the life of your humidifier and lower its output.

Introduction:

What is the problem with not using distilled water in a humidifier? The truth is you can get away with using tap water in a humidifier or a CPAP machine for a while. But eventually the mineral content will become a problem for your humidifier or CPAP machine.

This is true story:

Recently my wife had an issue with her CPAP machine. if you’re not familiar with what a CPAP machine is, it’s a device that helps you breathe while you sleep. It comes with a mask that you put on, that basically pushes oxygen into your lungs.

And just like a humidifier they are required to be filled with water.

As the story goes, this specific CPAP machine that my wife was using stopped working.

With some aggravation, She immediately she got a hold of the manufacturer who agreed that they would send a shipping label for her to send it in to get it fixed.

And just like they promised, the whole transaction went smoothly and they repaired the device and send it right back.

The invoice that was included in the package specified the problem:

“unit was clogged up, thoroughly cleaned and working properly again. Solution, switch to distilled water”

A lot of hassle and money to get a CPAP machine repaired to find out that she was using tap water to fill it, and the minerals in the water had eventually stopped up the machine where it would not function.

So do you have to use distilled water in a humidifier? No it will work with tap water, But eventually you may wish you would have.

Water Types for Humidifiers

Water Type Mineral Content Potential Impact on Humidifier Suitability for Humidifiers Maintenance Tips
Distilled Water Very Low Minimal scaling and buildup Highly Recommended Regular cleaning with less effort
Tap Water High Increased scaling, potential for clogging Not Recommended Frequent deep cleaning required
Bottled Water Variable Possible scaling depending on mineral content Better than tap, worse than distilled Regular cleaning recommended
Boiled Water Reduced Less scaling than tap water, but some minerals remain Better than tap, not as ideal as distilled Regular cleaning with attention to mineral buildup

Distilled Water For Humidifiers? Why is it Best?

Distilled water is the best water to use in a humidifier because of its low mineral content. Because of the process it goes through, it has the lowest mineral content of any type of water.

This is important for a few reasons:

1.The mineral content in most drinking water will eventually shorten the life of your humidifier and lower the output by stopping it up.

2. The minerals in most water are what is responsible for the dust that you see gathering around your humidifier.

Since dust is one of the primary reasons that your skin gets dried out in dry weather, using water with a lot of mineral content in a humidifier can produce the opposite effect than intended.

3. The higher the mineral content in the water that you use in a humidifier, the more likely, the growth of mold and bacteria in the water.

Can you use regular tap water in a humidifier

Can I Use Regular Water in a Humidifier?

Is it dangerous to use regular tap water in a humidifier. No.

Now more so than drinking tap water.

And though most of us probably drink bottled water more regularly than tap water, anytime you purchase tea or coffee from a restaurant, it’s going to be made with tap water.

So whether we believe that tap water is good to drink or not, most of us are most likely consuming it on a regular basis.

The issue with tap water being used in a humidifier are primarily about the high mineral content in tap water.

The higher the mineral content in the water that you use in a humidifier, the more likely to get stopped up and not work properly.

And it’s the mineral content in the water that creates the white dust that accumulates on the humidifier and around it.

Since dry skin is one of the primary reasons people purchase humidifiers and dust is one of the primary things that pulls the moisture out of your skin,
operating a humidifier that is creating more dust by using tap water somewhat counterproductive.

Another issue with tap water is that the minerals in the water have more of a chance to become food for mold to be able to take root inside of a humidifier.

Finally, tap water has a whole list of chemicals that are there “for our own good apparently” that you do not necessarily want to breathe in as part of the moisture content in your air.

Tell me again why they put “fluoride” in tap water?

So even though tap water is definitely not the best option for a humidifier, the issues with it are not immediately harmful or dangerous. And if that’s all you have at your disposal, you know the risk,

And it’s not like you can’t clean your humidifier extra well after you use tap water in it. And as for the dust, keep it wiped up.

bottled water for humidifierWhat other water besides distilled can you use in a humidifier?

Bottled?

Bottled water has a lot of minerals in it that could be an eventual problem for your humidifier. Even the water that is produced by using reverse osmosis has the disclaimer on it that minerals are added back to make it more consumable.

It’s a better option than tap water but it still has its fall backs.

Boiled water?

Boiling water causes the minerals in the water to settle. So if you had a way to separate the settlement so that it did not make it into the humidifier with the rest of the water, it would make a great choice.
The problem is, making that happen. Not exactly easy to do.

 

warning-dirty humidifier water ahead

But there is absolutely one type of water you should never run your humidifier with.

Stagnant water

Water that has been allowed to sit inside of your humidifier is going to be moldy and full of germs and bacteria.

And when you turn that humidifier on with that stagnant water still in it, the germs and bacteria in that water will become part of the air that you are breathing.

Now talk about having the opposite effect than you intended, the humidifier that was supposed to make you feel better, has basically become a weapon of germ warfare.

Legionnaires’ disease and humidifier lung are harsh reminders of what can happen when humidifiers and evaporative coolers are allowed to sit with moldy water.
You can easily look up the symptoms of mold allergies and discover that they look very closely like the symptoms of the flu.

So if you think that the humidifier in your house may be making you sick, you may be right. And you should take it seriously.

Fortunately, Humidifiers have become pretty sophisticated devices and many of them have ways of helping control mold growth.

If you’re in the market for a new humidifier, it’s well worth it to look into some of the features that can help reduce the chance mold and bacteria growing in your humidifier and becoming part of the air you’re breathing.

There are additives that you can place in your humidifier that can reduce the chances of a humidifier developing bacteria too.

Maintenance Tips for Humidifiers

Proper maintenance is crucial for ensuring your humidifier operates efficiently and safely, extending its lifespan and improving indoor air quality. Regardless of the water type you choose, here are some essential maintenance tips to keep your humidifier in top condition:

  • Regular Cleaning: Clean your humidifier regularly to prevent the buildup of minerals and the growth of mold and bacteria. Depending on usage, a thorough cleaning every 1-2 weeks is recommended.
    • Empty the water tank, dismantle the parts, and clean them with mild soap and warm water.
    • Use a soft-bristled brush to scrub away any mineral deposits or buildup.
  • Use Distilled Water When Possible: While not always necessary, using distilled water can significantly reduce mineral buildup and the need for frequent descaling, making regular maintenance easier.
  • Descale and Disinfect: Even with distilled water, it’s important to descale and disinfect your humidifier to remove any mineral deposits and kill germs that could be harmful.
    • Descale the humidifier by using a mixture of white vinegar and water. Let it sit for at least 30 minutes, then rinse thoroughly.
    • Disinfect the water tank and other parts by using a diluted bleach solution (1 teaspoon of bleach per gallon of water) or hydrogen peroxide. Rinse all parts thoroughly after disinfection to ensure no chemicals remain.
  • Change Filters Regularly: If your humidifier has a filter, follow the manufacturer’s recommendations for changing it. Filters can harbor mold and bacteria, reducing air quality and humidifier efficiency.
  • Dry Before Storing: If you plan to store the humidifier for an extended period, ensure it is completely dry to prevent mold and bacteria growth. Disassemble the parts, clean them thoroughly, and let them air dry before storing.
  • Monitor Humidity Levels: Use a hygrometer to monitor room humidity levels, maintaining them within a comfortable range of 30-50%. This helps prevent problems associated with over-humidification, such as mold growth and condensation on windows.
  • Check for Leaks and Damages: Regularly inspect your humidifier for any signs of leaks or damage. Addressing these issues promptly can prevent further damage and potential water damage to your surroundings.

Pros and Cons of Using Distilled Water in Humidifiers

Pros Cons
Minimizes Mineral Deposit Buildup: Cost:
Using distilled water reduces the accumulation of mineral deposits inside the humidifier, thereby extending its lifespan and maintaining its efficiency. Regularly purchasing distilled water can be more expensive than using tap water.
Less Maintenance Required: Accessibility:
Due to fewer mineral deposits, humidifiers operating with distilled water require less frequent cleaning and maintenance. Distilled water may not be as readily available as tap water, requiring extra trips to the store or the need to distill water at home.
Reduces White Dust Formation: Environmental Impact:
The low mineral content of distilled water minimizes the white dust that often accumulates around humidifiers using tap or hard water, leading to cleaner air and surfaces. Buying distilled water in plastic bottles can increase plastic waste, contributing to environmental concerns.
Prevents Microbial Growth: Not Always Necessary:
Distilled water is less likely to harbor bacteria and mold because it lacks the minerals and impurities that feed microbial growth in humidifier tanks. For some humidifiers, especially those with built-in filters or demineralization cartridges, the benefits of using distilled water might be less significant.

Summary


Do you have to put distilled water in a humidifier?

No. Even though distilled water is the best water to keep your machine from stopping up and extending the life of your humidifier,
A humidifier will work without it.

And though everyone agrees that tap water is the worst water you want to use in a humidifier, you can use it without having to worry about it being dangerous to you.

The main issue with tap water is that it is filled with minerals that can stop up your humidifier. And those minerals can and will produce humidifier dust on your unit and around it.

If tap water is what you have available, then do your best to keep your humidifier clean with vinegar and keep the dust around the humidifier wiped up so it does not become part of the air quality.

Arguably, The most important thing to remember when using a humidifier is to never run it with stagnant moldy water in it.

Mold in your air can produce very similar symptoms to the flu. Pneumonia, humidifier lung, and legionnaires are harsh reminders of what can happen when mold is allowed to grow in water unchecked.

Is 60 humidity Too High in a House? What About 70? 80?

60 humidity Inside the House? Is that Considered Too High?

Yes, an indoor humidity level of 60% is generally considered too high for most homes.
High indoor humidity can also lead to health issues by encouraging the growth of mold, mildew, and dust mites, which are common allergens and irritants. Furthermore, excessive moisture can damage your home’s structure and furnishings by causing wood to warp, paint to peel, and unpleasant musty odors to develop.

Humidity has a big effect on your health and property, and the truth is, it is much more serious than you probably ever gave it credit for. Both high and low humidity comes with its own problems and symptoms.

This article is about many of the symptoms and problems that you can expect with high humidity. And some solutions too.

40 to 60% relative humidity is the optimal range to protect your home and family from the spread of germs and avoid damage to your personal property.

A direct statement by ncbi.nlm.nih.gov
says “health effects caused by road of humidity would be minimized by maintaining indoor levels between 40 and 60%”

Humidity Level Symptoms
60% Nearing discomfort range, potential for mold growth, increased allergens like dust mites.
70% AC inefficiency, visible condensation, clammy skin, frizzy hair, sneezing, itchy eyes, increased mold and mildew growth.
80% Wheezing due to dust mites and mold spores, risk of dehydration, reduced physical performance, wood rot, damage to musical instruments, proliferation of fungi and bacteria.

Humidity 60 in the House

At 60%, the humidity in the house is nearing the outside of the range of what is considered comfortable and safe humidity inside of the home.

At 60% RH, you have already begun to enter into an area of relative humidity that can provide enough moisture in the air for mold to take root.

As that number increases, the likelihood of mold being found somewhere in your home increases.

The risk of mold growth increases significantly as humidity levels rise above 60%. And with mold comes mold spores. A significant household allergen.

70 humidity in house

At 70%, you are already noticing the telltale signs all around you.

The AC will begin to feel like it’s not running at all and condensation will be nearly pouring from it.

You will undoubtedly feel very clammy and will have no chance of dealing with your frizzy hair.

You might also find yourself sneezing and rubbing your itchy eyes.

Why is that?

It’s because dust mites thrive in temperatures that hover around the 70 to 80° range with a relative humidity of 70 to 80%.

In addition to the discomfort and presence of dust mites, high humidity levels like 70% can lead to other significant issues within your home.

The excessive moisture creates an ideal environment for the growth of mold and mildew, which can cause damage to your home’s structure and furnishings.

More importantly, mold and mildew release spores into the air, contributing to indoor air pollution and potentially leading to health problems such as respiratory issues, allergies, and asthma in susceptible individuals.

80 humidity in house

At 80% humidity, you may start wheezing because of the amount of dust mites and mold spores in the air.

And the risk of dehydration will become a real threat because your body will not be able to produce sweat nearly as easily at that level.

Your performance will be off and you will find that you’re not able to do as much without getting tired.

Humidity sustained at that level will begin to rot the wood around your home including window sills and floorboards.

And any musical instruments you have around the house will have probably gone way out of tune by now. And the risk of them bowing to a point that they may never play well again is serious.

Moreover, the pervasive dampness associated with 80% indoor humidity can lead to a proliferation of other allergens, such as fungi and bacteria, further compromising indoor air quality.

This environment not only exacerbates existing respiratory conditions but can also trigger new health issues among the home’s inhabitants.

Electronic devices and appliances are not immune to the ravages of high humidity either; the excessive moisture can corrode circuits and internal components, leading to malfunctions and a shortened lifespan for these items.

violin i

Uhh!!

As you can tell, a sustained high level of humidity is not good for your health or your home. If any of this describes your situation then you should be taking steps to remedy the situation.

Determine the Origin of the Humidity

Climate

Of course there’s not too much you can do about the weather. And if the outside humidity is shooting up then you’re inside humidity is going to shoot up with it.

Here’s a Few Solutions:

Air Conditioning

Refrigerated air conditioners, either the type you have built into your house via the HVAC or window air conditioners which would include portable air conditioners that vent out of the window, will reduce the humidity inside of the house.

This type of air conditioner pulls humidity out of the air, reduces it to condensation, and either drips or funnels it outside.

And most refrigerated ACs you find these days have a dehumidifier setting that will reduce the humidity in the room without having to have the cool function running. The dehumidifier setting on an AC is usually called “dry mode”. It’s symbolized by a water drop, if your unit has symbols instead of words.

Dehumidifier

The dehumidifier is a device that is similar to a refrigerator air conditioner except that it doesn’t have any type of cool setting.

It’s only function is to reduce the humidity.

Humidifiers exhaust heat similar to the way a window air conditioner does.If you have ever walked behind a window air conditioner then you probably remember feeling heat coming off of the unit.

But the heat that is exhausted on a dehumidifier is expelled inside of the room.

A factor you’ll want to consider when you’re thinking about operating a dehumidifier. Depending on the reason for the humidity, the heat exhausting from the machine it’s not exactly a welcomed feature if the temperature is already hot outside.

70 humidity in house

When is the AC not useful in humidity?

Even though refrigerator air conditioning is the easiest and most effective way to bring them the humidity level indoors, there are times when air conditioning will do the opposite.

AC humidity problems

1.  Running the AC with “fan on” setting engaged.

There’s a lot of confusion when it comes to running the air conditioner with the “fan on” setting engaged versus the “auto on” setting engaged.

The “fan on” setting well actually makes your home feel more humid.

The reason is, one of the primary ways that an air conditioner cools down a room is by extracting the humidity and turning it into condensation.

But when the “fan on” setting is engaged, the humid air that is being pulled into the air conditioner does not have a chance to stay in front of the condenser coils of the AC long enough to turn into condensation.

So the result is humid air being pulled into your air conditioner and redistributed throughout the house without the humidity being extracted.

2.  Too Large of an Air Conditioner

Another problem that can occur with air conditioning and humidity is that you have too large of an AC unit.

The result of running an AC unit that is too large for a home is a phenomenon called “short cycling”.

Which means that your air conditioner turns on and off more frequently.

This affects the way a air conditioner extracts humidity because the air conditioner is continually turning on and off,

and not giving the condenser coils enough time to turn the humidity into condensation and funneled out of the house.

humidity in house3.  Evaporative cooling

Evaporative coolers are essentially a large fan blowing over water as a means of cooling the air off.

Evaporative coolers are also known as swamp coolers because they can make a room feel swampy.

Number one, if you were trying to use a evaporative cooler when the humidity is high, you will not be able to feel anything much more than a fan coming from the unit at that point.

Number two, you are only adding more humidity to an already elevated moisture level.

And for some people this may be the reason your home feels humid in the first place.

Any devices or machines like evaporative coolers or humidifiers that disburse water droplets into the air, should not be operated when the humidity level is high in the house.

Leaking pipes

If you have above average humidity in your home but the climate outside is not especially humid, then you have another problem altogether.

Basements are usually known to be extra humid because of being located beneath the ground.

The moisture in the ground can find itself inside of your home.

Dehumidifiers can be outfitted with pumps and drainage hoses to reduce the humidity inside of a basement.

Leaking water pipes are also found in the basement quite often and can cause the humidity level to soar.

Telltale sons of leaking pipes inside of your home usually appear as drywall that is bowing or that feels damp to the touch.

Discoloration of the walls usually indicates a leak of some sort also.

Leaks in the ceiling are usually very easy to locate and are very noticeable because they appear as some liquid that has been spilled on the ceiling.

If the high humidity inside of the home is due to leaking pipes, then as you probably guessed, you’re going to need a plumber.

 

 

Is Breathing in Bleach Bad? What to Do If You Inhale Bleach Fumes

Is Breathing in Bleach Bad?

Yes, inhaling bleach fumes is detrimental as it exposes the respiratory system to sodium hypochlorite and chlorine gases, which can damage lung tissue and airways, leading to respiratory complications and chemical burns.

It can cause irritation to the eyes, skin, and respiratory tract, leading to symptoms like coughing, chest tightness, and in severe cases, respiratory distress.

Introduction.

Many of us know someone with a heightened sensitivity to strong odors, particularly the pungent smell of bleach. In my own home, that person is my wife.

The mere presence of bleach-based products in our cleaning routine is enough to trigger an immediate and unpleasant reaction for her. Even a task as mundane as cleaning the toilet with bleach is off-limits; it results in an instant headache and a wave of nausea for her.

This personal experience has led me to delve deeper into the effects of bleach exposure, emphasizing the importance of understanding and mitigating its impact, especially for those with heightened sensitivity.

Why Breathing Bleach is So Dangerous?

Bleach contains chemicals like sodium hypochlorite, hydrochloric acid, and sodium hydroxide. When bleach is mixed with water or acids, it releases chlorine gas. Chlorine gas can cause severe irritation and damage to the eyes, skin, lungs, and throat.

Inhaling chlorine gas can lead to coughing, wheezing, shortness of breath, chest pain, and fluid buildup in the lungs. At high concentrations, it can cause respiratory failure, pulmonary edema, and death.1

Effects of Breathing Bleach Fumes

Short-Term Effects Long-Term Effects
Coughing, choking Asthma
Throat irritation Respiratory infections
Burning eyes, nose, throat Lung scarring
Wheezing, chest tightness Chronic bronchitis
Nausea, vomiting Lung cancer

Exposure can irritate the eyes, skin, and respiratory tract. Short-term effects include coughing, choking, wheezing, nausea, and burning sensations. Long-term effects like respiratory infections, asthma, lung scarring, and even cancer can occur with repeated exposure.

Situations Where Bleach Inhalation Occurs

There are certain situations where bleach inhalation is more likely to occur:

  • Cleaning with bleach – Using bleach cleaners in small, poorly ventilated areas can allow concentrated fumes to build up.
  • Mixing bleach and other chemicals – Never mix bleach with products containing ammonia or acids, as this creates toxic chlorine and chloramine gases.
  • Accidents with bleach – Spilling bleach directly onto the skin or eyes can cause immediate burning and irritation.
  • Suicide attempts – Some use bleach to attempt self-harm through ingestion or inhalation. This is extremely dangerous.

inhale bleachWhat to Do When You Inhale Bleach

If bleach fumes are inhaled, it’s important to get to fresh air immediately. Other steps include:

  • Move the person away from the contaminated area.
  • Call emergency services like 911 immediately.
  • Administer oxygen if available.
  • Have them rest and avoid exertion.
  • Remove any contaminated clothing.
  • Flush eyes or skin with cool water if irritated.
  • Seek medical evaluation, even if symptoms resolve, as lung damage may have occurred.

Bleach inhalation requires rapid medical treatment to avoid complications. Never assume someone is fine just because initial symptoms like coughing have improved.2

How To Get Rid of Bleach Fumes

To reduce or eliminate bleach fumes in an area, follow these steps:

  • Ventilation: Open windows and doors to allow fresh air to circulate and disperse the fumes.
  • Air Purifiers: Use air purifiers with activated carbon filters which can help absorb chemical smells and fumes.
  • Neutralizing the Odor: Bowls of white vinegar or baking soda placed around the space can help absorb and neutralize odors.
  • Water and Lemon: Simmering a pot of water with sliced lemon can also help to purify the air and neutralize the bleach smell.
  • Fans and HVAC: Use fans to push air out and turn on the HVAC system to help filter the air.

How Long Do Bleach Fumes Last?

The persistence of bleach fumes can vary based on factors like the amount of bleach used, ventilation, and humidity levels. In well-ventilated areas, the fumes may dissipate within a few hours.

In poorly ventilated or more enclosed spaces, the fumes can linger for several days. Using air purifiers and increasing ventilation can speed up the process of removing fumes.

  • Medical Attention: If the headache persists or is severe, seek medical attention as it could indicate a more serious exposure.

 

FAQ

Does Inhaling bleach Make You Cough?

Yes, inhaling bleach can definitely make you cough. The irritation caused by the chemicals in bleach, such as chlorine gas, can lead to a reflex cough. The body tries to expel the irritating substance from the respiratory tract, leading to coughing, throat irritation, and potentially other respiratory symptoms.

Is it safe to mix bleach and vinegar?

No, never mix bleach and vinegar. Mixing bleach and vinegar creates chlorine gas, which is highly toxic if inhaled. Even small amounts of chlorine gas can irritate lungs and airways.

Can Inhaling Clorox Fumes kill you?

Yes, inhaling Corex fumes can potentially kill you. Inhaling concentrated amounts of bleach or prolonged exposure to fumes can lead to respiratory failure and death. Seek immediate medical help if bleach is inhaled.

What does inhaling bleach do to lungs?

Inhaling bleach irritates and damages the tissues of the lungs and respiratory tract. It can cause fluid buildup, swelling, and bronchospasms in the lungs. Long-term scarring, higher infection risk, and reduced lung function can result.

How long does bleach inhalation last?

Acute symptoms like coughing and sore throat may last for several hours after bleach inhalation. However, lung damage can persist much longer and certain symptoms like wheezing may continue for days or weeks after exposure.

Can you die from cleaning with bleach?

Extremely unlikely when used properly. But using bleach to clean small enclosed spaces can produce concentrated fumes. Prolonged exposure to high concentrations of chlorine gas can potentially lead to death in severe cases.

What does bleach do to your brain?

Bleach has no known effects on the brain when inhaled or absorbed through the skin. However, ingesting bleach can potentially cause brain damage from chemical burns and the body’s reaction to poisoning.

How much bleach does it take to kill you?

As little as one cup of bleach can kill if ingested. For inhalation, severe effects require prolonged exposure to very concentrated fumes exceeding safe exposure limits. The amount needed would vary based on the strength of the bleach.

Homemade AC Coil Cleaner- 5 DIY Recipes

Is it time too deep clean the HVAC system again?

Keeping the components of the central heat and air unit that you rely on for warm and cool air clean are essential for not only getting the best results out of your AC but also making sure your energy bill stays manageable.

The air conditioning evaporative and condensing coils carry a lot of weight in determining how well your AC unit is able to cool off your house.

ac coil cleaner alternativeWhen they get dirty it
can decrease the capacity of your unit to cool your home and increase the amount of energy it takes to do so. A air handler with dirty coils can actually increase your energy bill as much as 40%.

But the good news is, you do not have to pay somebody or spend a lot of money on a specific degreaser or cleaner to revive your AC’s copper coils back to their original shine and performance.

A perfect homemade AC coil cleaner for both your evaporative and condenser coils is as easy as going to your cupboard or medicine cabinet and pulling out a couple of household items that most people are sure to have around.

Best Homemade AC Coil Cleaners- Homespun Recipes

1. Vinegar and alcohol

  1. Half cup of vinegar
  2. Half cup of rubbing alcohol
  3. Baking soda

If this sounds familiar, it’s because it’s basically the same ingredients as DIY window cleaner.

Nevertheless, alcohol and vinegar are an excellent combination to make sure that any tiny debris stuck on the coils breaks completely loose.

If you have debris that won’t come off without a little scrubbing, baking soda is a natural cleaner that has a mild abrasive element to it that will help with scrubbing without damaging the coils.
Vinegar is also one of the best cleaning tools to remove mold and mildew.

2. Soapy water and baking soda

  1. Water
  2. Dish soap
  3. Baking soda

Another easy recipe with ingredients that most people have around the house. A bucket of water with a little bit of dish soap and some baking soda if you need something abrasive to loosen up anything stuck to the coils.

With any type of homemade AC coil cleaner, remember to use a light brush and take it easy on the coils. You don’t want to scratch the coils or bend the fins that protect the coils.

3. Bleach and Water

  1. Bleach
  2. Water

A three to one combination of water and bleach (bleach being the smaller portion) in a spray bottle is an excellent homemade solution to clean the coils on your air conditioner.
Not only will bleach kill mold and mildew, it will also help prevent it from coming back.

Warning: If you don’t like the smell of bleach or if you have any type of adverse challenges with bleach, you probably want to stay away from this option. The reason is there is a chance that the smell will creep into your ventilation and into your home.

Cleaning air conditioner coils with vinegar

4. Vinegar and water

Using a homemade AC coil cleaner made up of simply vinegar and water is an excellent easy do-it-yourself solution for cleaning the coils in your AC unit.

Equal parts:

  1. White vinegar
  2. Water

White vinegar is one of the most effective mildew and mold cleaners there is. It not only removes mold, it leaves behind disinfectant properties that hinders mold from coming back.

5. Homemade Enzyme Cleaner

Natural enzymatic cleaners use enzymes, typically derived from bacteria or yeast, to break down organic substances like grease, oil, and biofilm.

These enzymes act as catalysts, speeding up the cleaning process without the need for harsh chemicals, making them eco-friendly and safe for use around pets and children.

A simple homemade enzymatic cleaner recipe:

Combine:
2-3 medium-sized citrus fruits (such as oranges, lemons, or limes)
about 1 cup of sugar
around 4 cups of water

This mixture should be allowed to ferment in a sealed container for 2-3 weeks to develop the enzymes effectively. After fermentation, the liquid can be strained and diluted with water for use.1

6. Hydrogen Peroxide

Hydrogen peroxide works as an antifungal and antibacterial agent primarily due to its oxidative properties. This process not only helps in disinfecting the coils but also in removing mold and mildew, which can significantly impact air quality and the efficiency of the AC unit.

A recommended mixture is:

One part hydrogen peroxide to four parts water.

This solution can then be applied to the coils using a spray bottle. After spraying, allow the solution to sit for a few minutes to work on the mold and mildew, then rinse the coils thoroughly with water to remove any residue​.

mini split homemade coil cleaner7. Homemade Mini Split Cleaning Solution

Mini-split AC systems, known for their efficiency and flexibility, present unique maintenance challenges compared to traditional central air conditioning systems.
Their compact, ductless design requires specialized care, particularly for the indoor units that accumulate dust and allergens.

A tailored homemade cleaning solution for mini-splits can include:

A gentle, non-corrosive mixture such as diluted mild dish soap and water, or a half-and-half mix of water and white vinegar.

This solution can be applied using a spray bottle directly onto the coils and blower wheel of the indoor unit, avoiding electrical components.

After application, a soft brush or cloth can be used to gently remove any debris, followed by a clean water rinse to ensure no residue is left behind.

5.Compressed air and dust buster

What could be an easier solution to cleaning the AC coils than using an air compressor to simply blow off any debris.
Using a compressor to blow the debris and dirt off of the coils is very effective but just hitting the area with a sudden force of air will scattered dust and debris all through your AC unit.

So before using forced air to clean the unit, it is best to take a dust buster or vacuum with the right attachments to get and get as much dirt and debris up as you can beforehand.

Another reminder. The fins that surround the coils are made out of very light tin. Be careful not to barrel down with the air. Keep it three or four inches away to ensure you do not bend the fins.

6. Garden hose

On the evaporative side of the AC which is outside, you will find that keeping the area tidy around your AC unit will help your AC run much more efficiently.

Simply taking a garden hose and applying some of pressurized water to the outside of your unit and even into any of the inside that you can actually reach with a garden hose spray attachment will help your AC run easier and along with keeping the air conditioner filters replaced will give you less opportunities with your unit freezing over.

Cleaner Type Ingredients Effectiveness Suitable for Notes
DIY Vinegar Solution Vinegar, Water Moderate Light Mold, Mildew Eco-friendly, mild odor
DIY Baking Soda Mix Baking Soda, Water High Grease, Stubborn Dirt Mildly abrasive, neutral pH
Commercial Cleaner Various Chemicals Very High Heavy Build-up Potent, use with caution
DIY Hydrogen Peroxide Hydrogen Peroxide, Water High Mold, Bacteria Antifungal, antibacterial

Maintenance Schedule

For an effective AC maintenance schedule, consider the following guidelines based on your environment:

In dusty areas or homes with pets, clean the AC coils every 3 months to prevent buildup.

In less dusty environments, a bi-annual cleaning in spring and fall is sufficient.

Always ensure to replace or clean filters regularly, ideally every month, for optimal air quality and efficiency.

Safety Precautions

When using homemade AC coil cleaners, it’s crucial to prioritize safety.

Handle all chemicals, especially bleach, with care, using gloves and eye protection.

Ensure proper ventilation to avoid inhaling fumes.

When accessing outdoor units, use stable ladders and have someone spot you to prevent falls.

Always follow manufacturer guidelines for your AC unit to avoid damaging components.

Negative Side Effects of Air Purifiers (11- Disadvantages 11- Advantages)

Air Purifier Advantages and Disadvantages

There’s no doubt that air purifiers are one of the most marketed items that you can find anywhere. The claims about the effectiveness of air purifiers seem to reach new heights every year. Some of the claims made by some advertisers make air purifier sound more gimmicky or scammy than an actual appliance that has a real function.

Whichever side of the fence you fall on, there is more than enough ammunition to argue your side. Here we’ve laid out what we think are the biggest negatives and side effects as well as advantages to owning an air purifier.
<

Advantages Disadvantages
Save you money on allergy medications Initial and ongoing costs (filters)
Beneficial for babies’ health Hard to ascertain effectiveness
Can improve indoor air quality Potential ozone production
Reduce allergy and asthma triggers Can make the room dusty
Control pet dander Require regular maintenance
Reduce germs, bacteria, and mold spores Often noisy
Help mitigate odors May concentrate germs and bacteria
Assist in managing headaches and COPD Can worsen allergies in some cases
Reduce exposure to chemicals and VOCs Ineffective for immediate odors

Negative Side Effects of Air Purifiers

1. Air Purifiers are Expensive

Air purifiers are one of the more expensive appliances available for purchase. The price tag on many air purifiers makes you wonder how they could come up with such an exorbitant price for a filtering machine. The price tag doesn’t stop when you purchase the device either. Get ready to join the filter of the month club. Or at least the filter every 3-6 month club.

2.  Replacement Hepa Filters

Air purifiers require replacement filters. You cant really argue the amazing capacity of hepa filters to be able to remove allergens from the air. But the ongoing cost of replacing the hepa filter would be considered a major negative side effect of owning an air purifier.

3.  It’s hard to tell if they’re working

Unless you’re having a specific problem with indoor allergies and can pinpoint the exact spot or room where the allergies tend to affect you the most, it’s hard to tell if an air purifier is actually working.

Most of us just go along our daily lives breathing the air we’re given with no real issues. Sometimes owning an air purifier so that we can say we are breathing healthier air is like taking a multivitamin. You know you need it, but you may not even ever be able to tell a difference in the way you are feeling by taking it.

4. Ozone

Air purifiers that clean the air with negative ions and UV tend to make ozone as a by-product. Whether you believe that ozone is straight from the devil or you don’t mind a little ozone if it means you can effectively reduce airborne viruses, the fact remains that breathing too much ozone can aggravate your lungs.

Which kind of defeats the point of getting a machine to help you breathe better.
Most ionic air purifiers create will below the amount of ozone that would be harmful. But there is the problem of putting to large of an ionic air purifier into too small of an area and getting a Overkill of 03.

Ozone also has a sharp odor that is reminiscent of bleach. Another “defeats the point” type of scenario. If you’re using an air purifier to help reduce odors then you  don’t exactly want a machine that adds an odor in return.

5. Make the Room Dusty

Air purifiers tend to make the area around the air purifier extra Dusty. And air purifiers that use negative ions can cause dust to settle throughout the whole area. So much so that there is a term for it, “Grey wall syndrome”.

replace hepa filter6.  Require Regular Maintenance

Maintenance on an air purifier could be considered the same as replacing filters. But there are some types of filters that do not need replacing and can be washed. Most air purifiers have a pre-filter to capture larger airborne debris.

7.  Noisy

Most air purifiers are filtering machines that run similar to a fan that pulls dirty air and exhaust clean air. And just like a fan, they come with different speed settings that allow you to turn the fan up higher or lower. Many larger Hepa air purifiers advertise “white noise” as part of their benefits.

8.  Concentrate germs and bacteria

Air purifiers generally work like a fan in reverse that to pull allergens from the air into a filter. That makes the area around the air purifier that much more full of local debris in the air since the flow of the air is towards the air purifier. This is one of the reasons that sleeping next to an air purifier is not the best ideal.

9. Air purifiers can make allergies worse

Air purifiers can make allergies worse because they tend to pull the airborne  allergens in the room toward the air purifier. This can create a local area around the filter that is highly concentrated with airborne allergens. That’s why putting an air purifier next to your easy chair can actually make the air around your most comfortable seat seem worse.

10. Useless for immediate odors

Though there are many air purifier brands that do work well for removing residual odors with carbon filters, the fact is that air purifiers are pretty much useless to get rid of immediate odors. By immediate, I mean, fresh kitchen odors, chemical odors, or bathroom odors.

11. Useless for smoking

Along the same lines as strong cooking smells, you’re not going to have much luck clearing out the smell of smoke quickly. And if you were talking about a house that has a history of cigarette smoking, the lingering smell is not something that an air purifier will be able to get rid of very easily.
Cigarette and tobacco smoke tends to have a sticky residue texture to it that binds it to the furniture, curtains, walls, and floor.
Ozone generators are you usually used for these types of situations.

clean indoor airAdvantages Of Air Purifiers

1.  Save you money

Allergies are big business. And getting relief from indoor allergies is not cheap.

Antihistamines can run you up to 40 bucks a pop at the local pharmacy. And to get the good stuff you have to have a prescription from a doctor.

Factor in the time missed from work and you get the point. Money and more money.

A quality air purifier can filter out as much as  97% of household allergens.

By capturing airborne allergens before they become a reason to see a doctor or a purchase medication, an air purifier can work to save you money.

2. Great for Babies

Babies are very susceptible to all types of allergens and bacteria.

Using a HEPA air cleaner with a activated carbon filter included will help your baby breathe better without introducing anything into the air that might have an adverse effect.

An Air purifier can also reduce the need for using germ sanitizing wipes in which chemicals can stick around much longer than you might imagine.

Activated carbon in an air purifier can also help reduce the abundance of odors that can gather in the baby’s nursery or room.

Ozone producing air purifiers should be avoided to ensure that the babies developing lungs are not harmed.

There can be no doubt that clean air is important for a baby to grow strong.

do air purifiers work3. Government Statistics  

Statistics. You gotta love em.

But did you know that according to the CPSC Consumer Product Safety Commission,

Indoor air can be more seriously polluted than the outdoor air even largest industrialized cities?

The same research found it people spend as much as 90% of their time indoors and that indoor air pollution is more of a health risk then outdoor air pollution.

Modern building techniques not only provide tightly sealed buildings to better ensure that the temperature remains a constant,

They also keep indoor air pollution sealed inside as well.

Do air purifiers work? Yes, The right air purifier can help you is your family avoid being a statistic.

4. Help Reduce Allergy Symptoms

Allergies affect us all at some point and for some of us, it can be downright miserable.
And the first line of defense is usually  to get an allergy medication.

Medications like antihistamines are expensive and most people experience side effects like fogginess and feeling drowsy when using them.

A high quality air purifier can work to filter as much as 97% airborne dust, pollen and pet dander, mold spores and bacteria before they have a chance to turn into an allergy problem.

5. Reduce Asthma Tiggers

Many of the same household allergens like dust mites and pollen, mold spores and pet dander can result in much worse symptoms for an asthma sufferer.

Airborne pollutants that otherwise may be the norm can result in narrowed airways and not being able to your catch your breath for an  asthmatic.

Reducing triggers that can cause an attack is essential for an asthma sufferer.

A good air purifier can go a long way to help reduce airborne asthma triggers.

woman with pets6. Help Control Pet Dander

How many people have to alter their lives because they can’t exist in the same house as a cat?

Pet dander can produce awful symptoms in people that are allergic to it.

Uncontrollable sneezing and swollen eyes are typical for people allergic to dander.

What a lot of people do not know though, is that airborne pet dander can be controlled.

Dander is actually the bacteria left on a Pet’s fur after they lick and groom themselves.

Once it dries, it becomes airborne.

An air purifier with a true HEPA filter can work wonders when it comes to capturing pet dander out of the air.

7.  Germs and Bacteria Reduction

Controlling germs and viruses in the home is usually delegated to using antiseptic sprays and bleach wipes.

But according to the National Library of Medicine, there are air cleaning technologies that can leave viruses and bacteria inactive.

Bi polar ionization is a technology that when used in concert with a HEPA filter can effectively reduce germs and viruses in a room.

Adding an air purifier equipped with these technologies to your sanitizing arsenal can make a real difference when it comes to germs and viruses in your home.

8.  Mold Spores

A great deal of the population is allergic to mold spores.

Many of the problems that people have with mold or due to leaky pipes. Finding the area where the moisture is getting in and fixing it is the first step to control mold allergies.

But there are also many other areas that mold grow that are practically impossible to eliminate.

Though the use of an air purifier will not clean mold off of your walls, it can be very effective at reducing the populations of mold spores in your air.

One type of air purifier that is highly rated for reducing mold in the air is Photocatalytic Oxidation. Photocatalytic oxidation or PCO for short oxidizes mold spores and removes their ability to cause an allergic reaction.

do air purifiers work for pet allergies9. Odors

Foul odors or not only annoying and off-putting, they can be symptomatic gases and fumes lingering in the area.

Activated carbon is a type of air cleaning technology that is able to adsorb the the VOCs and gases that are at the root of the odor and leave your house feeling fresh again.

Do Air Purifiers Work? Yes, The Right Air Purifiers Really Work For Odors.

10. Help With Headaches

Dust in air can give you a headache. But it’s not just the dirt being kicked up in the air that’s the problem.

It’s what the dust is made up of.

Some of the ingredients that you can find in your average dust ball are dead skin cells, cockroach feces, dust mites, pollen and spores, and carcinogens from smoke.

No wonder you have a headache.

Intense smells can also give you a headache. Many people can develop an oversensitive sense of smell they can make even the smells like cologne and candles too strong.

An air purifier that uses a true HEPA filter and an activated carbon filter can be a game-changer when it comes to reducing airborne contaminants that cause headaches.

11. Help Manage COPD

Chronic Obstructed Pulmonary Disease or COPD is a lung disease that causes obstructed airflow to the lungs.

An air purifier is not a replacement for inhalers and other equipment for people with COPD but keeping the air as clean as possible is a must when everyday household allergens can interfere with catching your breathe.

Keeping quality air purifiers equipped with true HEPA and activated oxygen filters running throughout the home will help remove airborne irritants before they have a chance to be breathed in.

12. Chemicals and VOCs

VOCs are usually considered air pollution created by chemicals.

Many household products including hair spray, aerosol cleaners, nail polish remover, and crafting items like paint and glue can be toxic to breathe.

Other VOCs occur through off gassing, exhaust fumes, and cigarette smoke.

Symptoms of VOC exposure range from allergy type issues like sneezing and runny noses all the through sharp headaches and memory loss.

Air purifiers that contain a large weight of activated Carbon are what’s needed to combat Chemicals in the air.

Other technologies like PCO reduce VOCs as well. Be aware though that air purifiers that rely on creating a ionic reaction should be viewed more as a air cleaning treatment rather than a 24/7 filtering machine.
