How Long to Wait After Using an Ozone Generator

How long to wait after using an ozone generator

It is recommended to wait at least 1-2 hours after running an ozone generator before re-entering the treated space. Ozone dissipates naturally over time, but allowing enough time for the ozone levels to drop to safe levels is important.

Recommend Waiting Times

Here are some general recommendations for waiting times after running an ozone generator:

Space Type Minimum Waiting Time
Small room (bathroom) 1 hour
Medium room (bedroom) 2 hours
Large open space 4-6 hours
Whole house 8-10 hours

It’s best to verify ozone levels with an ozone monitor. Wait until the monitor reads 0.05 ppm or lower before re-entering. Extend the waiting time if higher levels persist.

Why You Should Wait

Ozone generators are effective at eliminating odors, mold, bacteria, and other contaminants through oxidation. However, ozone is a lung irritant at high concentrations. Prolonged exposure can cause chest pain, coughing, shortness of breath, and throat irritation. Allowing ozone levels to decrease before re-entry prevents these negative health effects.

Here are some key reasons why waiting is recommended:

  • Allows ozone concentration to drop to safe levels – Government agencies suggest levels below 0.05 ppm.
  • Reduces risk of breathing difficulties, coughing, and irritation.
  • Prevents ozone buildup in enclosed spaces.
  • Gives time for ozone to fully react with contaminants.

How Long Ozone Persists

Ozone has a short half-life and breaks down relatively quickly, especially with proper ventilation. Here are some general timelines:

  • At very high concentrations (50+ ppm), ozone can persist for 1-2 days.
  • At moderate concentrations (5-10 ppm), ozone lasts up to 10-12 hours.
  • At low concentrations (0.1 ppm), ozone persists only 1-2 hours.

Ventilating the area speeds up ozone dissipation. Opening windows, running fans, or using HVAC systems can reduce ozone levels faster than just waiting for natural breakdown.

Safety Tips

Here are some additional tips for using an ozone generator safely:

  • Never occupy a space during ozone generation.
  • Post signs indicating ozone use.
  • Run generators when area is unoccupied.
  • Ventilate the space if possible.
  • Start with the minimum runtime recommended.
  • Check ozone levels with a monitor before re-entry.

Taking the proper precautions allows ozone generators to be used effectively while avoiding potential hazards.

Whole-House Steam Humidifiers: Benefits and Considerations


What is a Whole House Steam Humidifier?

A steam humidifier is a specialized type of whole-house humidifier that integrates directly into a home’s HVAC ductwork.

True to its name, it employs a steam-generation technique by boiling water to produce steam. This steam is then efficiently distributed throughout the entire house via the duct system, effectively increasing the humidity levels across all rooms.
This method not only ensures a uniform distribution of moisture but also provides precise control over the indoor humidity levels, making it an ideal solution for maintaining optimal indoor air quality and comfort throughout your home.

Benefits of using a steam humidifier:

Steam humidifiers offer a wide array of advantages over other types of humidifiers like evaporative and ultrasonic models, especially in the context of whole-house humidification.

However, a key benefit that truly sets steam humidifiers apart and boosts their popularity is their water boiling process. By heating water to create steam, these humidifiers naturally purify the water, significantly reducing the presence of mineral dust and eliminating germs.

This feature not only ensures a more consistent and efficient distribution of humidity throughout large areas but also provides a cleaner, healthier air quality, making steam humidifiers a preferred choice for maintaining optimal indoor comfort and health.


Types of steam humidifiers:

Type Description
Console humidifiers Free-standing units with an internal reservoir, heating element, and fan to distribute steam.
Electrode humidifiers Use electrodes in the water that boil the water to produce steam.
Canister humidifiers Portable units with a removable water tank.


Comparison of Steam Humidifiers with Other Types

Steam humidifiers excel in large-scale applications, offering precise control and efficient performance without the drawbacks of mineral dust or frequent maintenance. Their quiet operation and ability to integrate into existing HVAC systems make them an ideal choice for comprehensive home humidification solutions.

Who can benefit from a steam humidifier?

A steam humidifier, particularly the whole-house variety that integrates with a home’s HVAC system, is best suited for specific circumstances where its unique advantages can be fully leveraged:

  1. Large Homes or Spaces: Given its capacity to distribute moisture evenly throughout extensive areas, a steam humidifier is ideal for larger homes where maintaining consistent humidity levels in every room is challenging.
  2. High Demand for Precise Humidity Control: In environments where maintaining an exact humidity level is crucial, such as homes with sensitive woodwork, artwork, or musical instruments, the precise control offered by steam humidifiers is invaluable.
  3. Cold Climates with Heavy Heating Use: In areas where the heating system is frequently used, indoor air can become extremely dry. Steam humidifiers can effectively counteract this by integrating with the heating system to provide necessary moisture.
  4. Health-Related Needs: For households with occupants who have severe respiratory issues, allergies, or skin conditions aggravated by dry air, the clean and consistent moisture output of a steam humidifier can provide significant relief.
  5. Integration with Smart Home Systems: For homeowners who prioritize smart home technology and seek seamless integration with existing HVAC systems for centralized control, steam humidifiers are an excellent fit due to their compatibility and efficiency.
  6. Areas with Hard Water: The boiling process of steam humidifiers can help minimize issues related to mineral buildup, making them a suitable option in regions with hard water, where other types of humidifiers might struggle or require frequent maintenance.

In these scenarios, the unique features of a steam humidifier—such as its ability to provide rapid, consistent, and controlled humidification over large areas—make it an optimal choice for effective whole-house humidity management.


Flow-Through Humidifiers

Is it true that steam humidifiers are the best for avoiding the dangers of humidifiers mold and bacteria?

Like we briefly touched on before, there are some advantages to steam humidifiers when it comes to avoiding mold and bacteria, but they are not completely immune to these issues:

Steam humidifiers boil water, which can help kill mold spores and bacteria that might be in the water. However, this is only effective if the water reservoirs are cleaned regularly.

Steam humidifiers don’t require wicks or filters that can trap mineral deposits and microbes. However, the steam outlet and any surfaces the steam touches can still allow mold growth if not cleaned.

Steam humidifiers add dry steam to the air rather than cool mist, which is less likely to promote surface condensation that can lead to mold.

However, steam humidifiers still require proper maintenance to prevent mold and bacteria:

1.The water reservoir should be cleaned regularly with a disinfectant to kill any mold or bacteria.
2.Any surfaces the steam comes into contact with should be cleaned to prevent microbial growth.
Steam humidifiers, like other types, can spread microbes in the air if the water reservoir contains any contaminants. Always use clean water.

Are Steam Whole House Humidifiers better at avoiding mold and bacteria than the other types of whole house humidifiers?

Yes, in general steam humidifiers are better at avoiding mold and bacteria growth compared to other types of whole house humidifiers:

1.Evaporative humidifiers require wicks and filters that can promote mold growth if not cleaned regularly. The standing water is also prone to bacterial growth.

2.Ultrasonic and impeller humidifiers produce cool mists that can condense on surfaces and promote mold.

By contrast, steam humidifiers boil the water, killing many microbes. And they don’t require wicks or filters.

However, steam humidifiers are not foolproof:

If not cleaned regularly, mineral deposits can accumulate in the water reservoir and provide an environment for microbial growth.

Steam can condense on humidifier surfaces, allowing mold if not cleaned.
Adding steam to air can make dust particles and allergens airborne.
So while steam humidifiers have an advantage, proper maintenance is still crucial

Do You Need A Boiler Present?

Steam humidifiers do have higher energy demands compared to other types of humidifiers, which can make them more expensive to operate, especially if a boiler is not already present.

Here are some factors to consider regarding the costs of steam humidifiers:

Steam humidifiers require heating water to boiling temperatures, which uses more electricity than cool mist options. This can drive up energy bills.

Installing a steam humidifier without an existing boiler/furnace can require running new steam lines, condensed water returns, and installing a water heater to generate steam. This significantly increases upfront costs.

Without a boiler, standalone electric steam humidifier units are available, but energy costs may still be high depending on humidification needs.

Ongoing costs are higher as mineral deposits in hard water can cause scaling in steam humidifiers, requiring frequent maintenance and part replacement.

However, in a large home a steam humidifier may be the only option capable of properly humidifying the whole space. Their higher output can justify the costs.

In summary, for homes without an existing steam system/boiler, the costs of installing and operating a steam humidifier are often prohibitive.

Cool mist and evaporative options are more affordable.

But steam systems make sense for larger homes if the initial investment can be accommodated. As with any system, considering long term costs and benefits is advisable.


How do steam humidifiers increase humidity?

Steam humidifiers boil water in a reservoir to produce water vapor or steam. This steam is dispersed into the air through a built-in fan or existing HVAC system ducts. As the steam evaporates in the air, it raises the humidity level.

What maintenance is required for steam humidifiers?

To avoid mineral deposits and microbial growth, steam humidifiers require:

– Daily water changes
– Regular cleaning/disinfecting of tanks
– Descaling agents to remove mineral deposits
– Replacement of filters, wicks, and gaskets

How often do steam humidifier filters need replacement?

Most manufacturers recommend replacing steam humidifier filters every 1-2 months of use. Hard water and frequent operation may require more frequent filter replacements.

Can steam humidifiers lead to mold growth?

Yes, steam humidifiers can promote mold growth if not properly maintained. Mold can grow in mineral deposits or on surfaces where steam condenses. Proper cleaning and disinfecting of tanks, filters, and surfaces is essential.

Are steam humidifiers safe for pets?

Steam humidifiers are generally safe for pets as long as hot surfaces are out of reach to avoid burns. The steam itself is not hazardous. Proper maintenance is key to avoid mold and bacteria that could pose a health risk.

How often should the water tank be cleaned in a steam humidifier?

The water tank or reservoir in a steam humidifier should be drained, cleaned and disinfected daily to help prevent mineral deposits and bacteria growth. Weekly deep cleanings are also recommended.

Can I use a steam humidifier in a bedroom?

Yes, steam humidifiers can be used in bedrooms, but precautions should be taken. Avoid very hot steam emissions. Place the unit far from beds and aim steam away from sleeping areas. Monitor humidity levels to avoid condensation.

Are steam humidifiers energy efficient?

No, steam humidifiers require boiling water so they typically use more energy than other types of humidifiers. Their energy efficiency can be improved by insulating steam lines, proper sizing, and using energy efficient models.

Does water quality affect a steam humidifier?

Yes, hard water with high mineral content can cause scale buildup in steam humidifiers. This requires more frequent maintenance. Using filtered or distilled water can help reduce deposits.

How can I prevent white dust from my steam humidifier?

White dust is caused by mineral deposits from hard water. Change water daily, use distilled or filtered water, clean scale buildup regularly, and replace filters as needed to prevent white dust.

Can I install a steam humidifier myself?

Steam humidifier installation is complex, especially if steam lines need to be run. Hiring a qualified HVAC technician is highly recommended unless you have expertise in steam system installation.


Basement Window Air Conditioning- What are the Options?

Solutions for Basement window air conditioning

Basement air conditioning options include portable AC units, window AC units, and ductless mini-split systems, each providing efficient cooling by utilizing refrigerant cycles to transfer heat from the interior to the exterior.

For integrated solutions, central air systems can be extended to basements, using ductwork to circulate cool air, optimizing thermal exchange through a centralized compressor and evaporator system.

Main Options for Window AC in Basement

AC Type Cooling Capacity (BTUs) Installation Complexity Noise Level (dB) Features
Portable AC 5,000 – 14,000 Low 50 – 65 Mobility, dehumidification, no permanent installation
Evaporative Air Cooler Not measured in BTUs Low 40 – 60 Adds humidity, energy-efficient, best in dry climates
Ductless Mini-Split 9,000 – 36,000 Moderate to High 19 – 34 Quiet operation, efficient, no ductwork required
Central AC Extension Varies by system High Varies by system Integrated with existing HVAC, consistent cooling


Putting a window air conditioner in the basement seems like it would be easy proposition. Go down to the local hardware store, buy a window AC, pop it in the window, and call it a day.

But as it turns out, basement window air conditioners are not exactly an item you can find very easily,  if at all.

What’s more is the issue of the window being one of the only ways to ventilate the basement and the fact that basements tend to be a high concentration zone of airborne molds and bacteria.

Not exactly something you want recycling through your air conditioner and in the air you breathe.

And this..

Having something obstructing the only opening in and out of the basement in case of a fire blocking the door is another issue you have to consider when you’re talking about using window there is a air conditioning point in the basement.

So what are the cooling options for a basement?

what are the cooling options for a basement?

What is the Best way to air condition  a basement?

Consider this..

Basements, being that they are underground are usually not that prone to excessive temperatures.

And in most cases suffer from being stuffy from the high level of humidity and musty atmosphere created by the level of toxins associated with moldy basements.

And even if you could find a window air conditioner that would fit in a hobbit window, you would still have the problem of the air conditioner recirculating the moldy room air.

The point is..

The comfort level in the basement might very well be more of a case of ventilation and dehumidification.

1.  Portable air conditioner

This is the easiest alternative to a window air conditioner is a Portable AC.  Its because portable air conditioners and window air conditioners are basically the same thing.

The only difference is, one sits in a window and exhaust outside. The other one is meant to be more portable and a hose to exhaust from. Yet the hose still needs to have a window to exhaust too.

Since basement windows or Hobbit Windows as they are also called are typically narrow, attaching the hose from a portable AC is an obvious alternative to a window AC.

Some augmentation and DIY ingenuity will probably be needed to outfit the window to make a sealed opening for the hose.

2. Mini split air conditioner.

A mini split air conditioner is also a perfect alternative to a window air conditioner in the basement because you just need a wall to place it.

The whole unit is like a miniature central heat and air system that cools and heats inside and and a separate compressor that sits outside.

The price of a mini split system maybe a little more than a portable AC but in the end, probably worth it.

Not only for the superior cooling and heating capacity, but also for the finished look.

A tidy looking ac unit compared to a unit on wheels that has a bulky looking hose. You would be much happier with the look of a mini split system.

The installation of a mini split system is is a little more tricky. It requires some through the wall hole making. And some connecting that a lot of people may not be too comfortable trying themselves. A heating and air professional can be brought into handle this.

3.Ventless AC

A ventless air conditioner is another way of saying Evaporative cooler. Also called the swamp cooler.

Though it might seem like a great idea when you first hear it because it doesn’t require any type of venting, putting in the ventless cooler in the basement is actually riddled with problems.

The first issue is, they require water. Lots of it.
That means a permanent hookup or carrying a lot of water down stairs. Over and over.

The basement is already a problem area for excessive humidity.
Placing a swamp cooler in a basement will only add to the problem and help exasperate the issues with mold and bacteria.


Evaporative coolers aren’t very effective in areas with high humidity.


There is always exceptions to the rule. If you already have a ventilation and dehumidifier system in place, a portable evaporator cooler could be a great option for helping cool down the basement.

4. New HVAC zone

If you’re home is already outfitted with central heat and air, then there is the possibility that your unit has enough power to set up a new zone to your basement.

Running vents off of your already existing system is a great way to get cooling to your basement.

But remember that just adding a couple of more ducts and vents it’s not necessarily going to suffice.

You are going to need a professional to come in and set up a new zone for your basement in order to get even cooling in the basement and not diminish the cooling in another area.

can you use a window ac without a window

5. DIY basement window air conditioning

If you already have a window air conditioner that you were trying to figure out how to use in the basement, then you already know that just putting the air conditioner in the room with you is not going to work.

If you haven’t tried it, here is the reason.

Window air conditioners exhaust heat out the back side.
Just placing a window air conditioner in the room with you will create cooling out of the face, but create heat out of the back.

So basically canceling each other out.

if you had a way of engineering something DIY style, you could use the window air conditioner as long as you had a way venting the heat expelled from the rear of the AC.

Here’s an example of a do-it-yourself window air conditioner turned mobile that could work in the basement as long as you have a hobbit window handy.

Here’s a more detailed look at it.

The whole idea is to take a large storage tub complete with lid and exhaust the heat from the air conditioner into the storage container which is ducted into the small Hobbit basement window.

Though it’s not the prettiest, it can be utilized and would work well for basements that are primarily used as shops, crafting rooms, so forth.

And one of the advantages is that refrigerated air conditioners, be it window or portable, dehumidify as part of the cooling process.

And since basements are notorious for high humidity, having a refrigerated air like a portable or a DIY window air conditioner can be very beneficial.

Wrap up

The ideal of putting a window air conditioner in your basement get shot down pretty quickly when you find out that they’re or actually very few if any window ACS that will actually accommodate the small basement window.

But if you are willing to think outside of the box, there is more than one way to skin a cat.

In this article we shared a few ideals on how to use existing products like ventilation fans and mini split air conditioning units as well as portable ACs to get air conditioning to your basement.

We also spoke about the possibility of using your window AC inside the basement but only adding a DIY twist to it.

Whether you are the DIY type or whether you are looking for something that is much nicer then you can get out of a do-it-yourself project, we hope that the suggestions we presented have sparked some of your own ideals to get air conditioning into your basement.

Do I Need a Humidifier or Dehumidifier for a Stuffy Nose?

Stuffy Nose Solutions: Choosing Between a Humidifier and Dehumidifier

When dealing with a stuffy nose, the choice between a humidifier and a dehumidifier hinges on your home’s current humidity levels.

A humidifier is beneficial in adding moisture to the air when indoor humidity is below the optimal range of 40-60%, often during dry winter months or in arid climates.

Conversely, a dehumidifier is useful for reducing moisture in overly humid conditions, which can be common in hot, damp climates or during rainy seasons, to mitigate allergens like dust mites and mold that thrive in high humidity and can exacerbate nasal congestion.

Here’s a table to help you decide:

Condition Humidity Level Recommended Device Reason
Dry Indoor Air Below 40% Humidifier To add moisture and alleviate dryness-induced stuffiness
Excessively Humid Air Above 60% Dehumidifier To reduce moisture and control allergens causing congestion

Do you have a stuffy nose? Is Congestion stopping you from thinking great thoughts? Oh the humanity… or is it the humidity?

The humidity outside and inside seems to have a lot to do with a lot of things. But what things? That’s not always too clear.

Stuffy Nose Dilemma: To Humidify or Dehumidify?

It depends.

Is the humidity in your home too high or too low?

A humidifier is to add humidity to a room or space when the relative humidity is too low.

A dehumidifier extracts humidity from the air when the humidity level is too high.

Another way to put it..

Is it winter outside and the house is dried out from the heater being on?

Or is it hot and humid outside and you’ve got a frizzy hairdo to go with your stuffy nose?

Stuffy Noses can happen when the humidity is too high and when the humidity is too low.

Dry air can cause you to feel stopped up and humid air can also cause cold-like symptoms because of dust mites and mold spores, along with other allergens.

What Should the Humidity be Set at?

According to NIH “The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60%”.

So if your hygrometer is sitting at 50%,  the relative humidity in your home is good.

But if you’re below 40%, using a humidifier to add moisture back into the air is the device that will help you correct your humidity and hopefully get you breathing through your nose better again.

If the relative humidity according to your hygrometer is sitting above the 60% mark, then your stuffiness may be due to allergens and dust mites which can be found in the air, when the humidity is too high.

How do you know what your humidity level isKeeping your Humidity Copacetic (steady as she goes)

Humidity levels inside your home can often be corrected by doing a few things to keep the good in and stop the bad from getting in.

Excessive Humidity

Windows and doors are an easy place to start. Moisture can find its way indoors through the smallest of cracks. And when your windows have not been resealed for a long time, excessive humidity around the windows can cause the seals to warp and rot.

Ceiling of the windows with some caulking and weather stripping can help even out your relative humidity.

Extraction fans or another easy fix.
Those houses come equipped with extraction fans in the bathroom and kitchen and some even have them in the washroom.

Extraction fans are fairly inexpensive and can be put into the ceiling quickly.

Anytime you’re cooking with boiling water or taking a steamy shower or just washing the clothes, using your extraction fans will pull moisture out of the house and into the Attic.

Leaking pipes?

Other sources of humidity in the house can be coming from places or things more undesirable.
For instance if you have plumbing problems or a broken pipe that is leaking inside the house, you are going to be experiencing excessive humidity especially in the area where the pipe is broken.

Leaks not only cause humidity, they cause mold. And mold that has gone unchecked for very long can turn into a big problem fast.

And if you have mold allergies, you may have discovered why you were suffering with a stuffy nose in the process.

Water under the house.

Any water that gets underneath the house can cause humidification to rise from under the floor. This can also be a source of mold and affect your air quality to the point of suffering from allergy symptoms.

Sometimes water under the house can be corrected by stopping any type of ravine that has been maybe etched out by watering the grass. Putting a barrier in front of the water runoff will help it to keep from running beneath your home.

Crawl space encapsulation is a big process that entails putting a plastic barrier between the ground and your house.

Broken and stopped up gutters can also direct water to flow beneath the house.
Fixing these items can often keep the humidity down inside of your home.

Run the air conditioner.

Many times, we forget that the air conditioner works as a dehumidifier to reduce moisture in the air as it cools the air down.
Most modern air conditioners have a dehumidifier setting ready available so that you don’t have to have the cool setting running at the same time.

Basement Dampness

Basements tend to be damp and humid by nature. Since the walls are typically concrete that are built against the moist ground, moisture has a way of working itself into the basement through the concrete.
Sealing up any cracks in the concrete wall is a must to keep moisture out.

The excessive humidity in the basement makes it a less than desirable spot to hang out or sleep. The air quality in the basement can also be responsible for allergy symptoms.

Low Humidity Remedies

Some of the easiest low humidity remedies for your home can be found in the same place that you’re trying to keep the humidity out of in the hot and humid season.


One of the easiest ways to add some humidity back into your room is to take a long hot shower and leave the doors open. That will allow the steam to migrate into the adjoining rooms as well.

Taking more baths than showers?

Leaving the bathwater in the bath after you bathed will help humidify the area around the bathroom as well.

Dry air pulls humidity from anywhere I can. That’s why dry and cracking skin is such a huge symptom of low humidity.

Cups of water around the house.

Simply leaving some containers of water open around the house can help alleviate some of the dry air. But remember stagnant water can develop bacteria fairly quickly and cause other types of problems. So don’t fill up a 5 gallon bucket so you don’t have to mess with it later.

Boiling water.

This is an old trick I remember from growing up. Mom always had water simmering and boiling in the kitchen and on the heater vents that used to be part of the floor back when.

She often put Vicks and other essential oils in the water to disseminate throughout the house.

Leave the washroom door open.

This may be a little bit on the iffy side if you have any type of allergies to detergents that can make it into your airstream if you leave the washroom door open.
But if you don’t, leaving the washroom door open while you’re washing clothes can invite humidity into the surrounding area.

Leave the dishwasher.

Another one is as simple as leaving the bathwater. Let the dishwater sit after you’re done washing the pots and pans and let the water naturally condense into your Air.H

stuffy noseRecap.

Should you use a humidifier or a dehumidifier when you have a stuffy nose?

The answer depends on whether humidity is too low or too high at the moment.

Low humidity can cause raw stuffy noses, where high humidity can be full of dust mites and bacteria that equates to having a stuffy nose.

A hygrometer is an inexpensive tool that can measure your humidity and tell you exactly or near exactly what your relative humidity is sitting at.

If it is below 40%, then your air is too dry and you need a humidifier to raise the moisture level.

If the humidity is above the 60% mark, then you need a dehumidifier to reduce the humidity.

And the humidifiers and dehumidifiers can be awesome tools, they are not always needed.

There are many things you can do around the house to lower and raise your humidity without purchasing any type of device.

Shutting the bathroom door or leaving the bathroom door open depending on the season is an easy way to add and diminish some of the humidity in the house.

Bypass Humidifiers: The Complete Guide to Integrated Whole Home Humidification

Bypass Humidifiers: A Buyer’s Guide

Maintaining the right humidity level in your home is important for comfort and health. When air gets too dry, it can cause problems for you and your house. Bypass humidifiers are a simple solution that work with your heating and cooling system to keep the air just right.

Let’s find out how they help make your home more comfortable.

What is a Whole House Bypass Humidifier?

A bypass whole house humidifier is a type of humidification system designed to work with your home’s existing heating and cooling system (HVAC) to maintain optimal humidity levels throughout the entire house.

It’s called “bypass” because it utilizes a bypass duct to circulate air through a water panel or pad, where the air picks up moisture before being redistributed throughout your home.

This process happens when the air inside your home is drier than what the humidistat, a device that measures humidity, determines is optimal.

Excess water from the humidification process is then directed back into the plenum (a central air distribution space for your HVAC system) via the bypass duct, avoiding over-humidification. This system is particularly effective in cold climates where indoor air tends to be dry, especially during winter months.

It is integrated into the home’s HVAC ductwork and typically installed near the furnace to leverage the existing airflow within the ducts to distribute humidified air.

What are the advantages of using a bypass whole house humidifier?

Using a bypass whole-house humidifier offers several advantages compared to other types of whole-house humidifiers like drum or steam humidifiers:

    1. Energy Efficiency: Bypass humidifiers are generally more energy-efficient than steam humidifiers because they don’t require electricity to generate steam. They utilize the airflow from your existing HVAC system to evaporate water on the humidifier pad, adding moisture to the air without additional energy consumption for evaporation.
    2. Lower Installation Cost: Compared to steam humidifiers, bypass humidifiers typically have lower initial installation costs. This is because they integrate more simply into existing HVAC systems without the need for independent electrical connections that steam humidifiers might require.
    3. Low Maintenance: While all humidifiers require maintenance, bypass humidifiers often have a straightforward maintenance routine compared to drum humidifiers. Drum humidifiers have a reservoir of water that can become a breeding ground for bacteria and mold if not cleaned regularly. Bypass humidifiers, which use a flowing water design rather than standing water, typically face fewer issues with microbial growth.
    4. Effective Humidification for Multi-level Homes: Due to their integration into the HVAC system, bypass humidifiers can effectively distribute humidified air throughout the entire home, including multi-level houses. This can be more efficient compared to portable units or single-room solutions.
    5. Water Conservation: Bypass humidifiers are designed to recirculate excess water back into the system rather than wasting it. This can be a more water-efficient solution compared to some steam humidifiers that might use more water to generate steam.
    6. Quiet Operation: Since bypass humidifiers use the air flow from the HVAC system and do not have their own fans or boiling elements, they tend to operate more quietly than steam humidifiers, which may produce noise during the boiling process.
    7. Compatibility with Existing Systems: Bypass humidifiers are typically compatible with a wide range of HVAC systems and can be a good option for homes with existing forced-air heating and cooling systems. This makes them a versatile choice for many homeowners.

Advantages of Bypass Humidifiers

Advantage Explanation
Energy Efficiency Uses existing airflow, no extra energy for evaporation
Lower Initial Cost Less complex than steam systems, so cheaper to install
Maintenance Simpler than drum, less frequent than steam systems
Effective for Multi-Level Homes Uses HVAC ducts to distribute humidity evenly
Water Conservation Recirculates excess water, minimal waste
Quiet Operation No fans or boiling sounds, quieter than steam humidifiers
Compatibility Works with most existing HVAC systems, versatile

How does a Bypass humidifier differ from other types of whole house humidifiers?

Bypass humidifiers differ from other types of whole-house humidifiers mainly in their design and operation.
Here’s a comparison with the two other common types: drum and steam humidifiers.

Bypass Humidifiers

      • Operation: Uses the HVAC system’s air flow to move air through a water panel, adding moisture to the air.
      • Installation: Integrated into existing HVAC ductwork, often requires less space than steam systems.
      • Maintenance: Requires regular maintenance, including annual replacement of the water panel and cleaning.
      • Energy Efficiency: Does not require additional electricity to create humidity; it uses the air flow from the HVAC system, making it energy-efficient.
      • Cost: Generally lower installation costs compared to steam humidifiers but may be higher than drum systems.

Drum Humidifiers

      • Operation: Contains a rotating drum covered with a foam or fabric sleeve that picks up water from a reservoir and evaporates as air blows over it.
      • Installation: Installed in the HVAC ductwork similar to bypass but typically easier and cheaper due to fewer parts.
      • Maintenance: Higher maintenance due to the risk of mold and bacteria growth in the standing water of the drum.
      • Energy Efficiency: Similar to bypass humidifiers in terms of not needing extra electricity for evaporation.
      • Cost: Usually the least expensive option in terms of initial investment.

Steam Humidifiers

      • Operation: Electrically boils water to create steam, which is then introduced into the ductwork.
      • Installation: More complex and can be installed independently of the HVAC system’s operation cycle, making it versatile for different setups.
      • Maintenance: Typically less maintenance compared to drum humidifiers but more than bypass since it involves more complex components like heating elements.
      • Energy Efficiency: Less energy-efficient due to the electricity needed to boil water, but provides precise humidity control.
      • Cost: Higher initial and operational costs due to the complexity of the system and energy usage.

Each type of whole-house humidifier offers distinct advantages and potential drawbacks, depending on your home’s specific needs, the climate you live in, and your preferences for maintenance and operational efficiency.

Types of Whole House Humidifiers

Type Operation Installation Complexity Maintenance Requirements Energy Efficiency Cost Implications
Bypass Uses airflow from HVAC to evaporate water from a pad Moderate Annual pad replacement, regular cleaning High (no additional energy for evaporation) Lower installation cost, moderate maintenance cost
Drum Rotating drum absorbs water from a reservoir Easier Frequent cleaning due to standing water risks High (no additional energy for evaporation) Lower installation and maintenance cost
Steam Boils water to create steam More complex Less frequent (cleaning and descaling) Lower (energy used to boil water) Higher installation and operational cost

How Does a Whole House Bypass Humidifier Work?

  • Connection to Water Supply: The bypass humidifier is connected to your home’s water supply. This allows it to draw water as needed to add moisture to the air.
  • Water Panel or Pad: Inside the humidifier, there’s a component called a water panel or pad. This is like a sponge that absorbs water from the supply line.
  • Airflow Through the Water Panel: Your furnace or air handler pushes warm air through the water panel. As the air passes through, it picks up moisture from the wet panel.
  • Bypass Duct: A special duct called a ‘bypass duct’ is used to direct some of the air from the heating system into the humidifier. After the air picks up moisture from the water panel, it rejoins the main air flow and is distributed throughout your house.
  • Humidistat Control: The system includes a humidistat, which works like a thermostat but for humidity. You set it to your desired humidity level, and it tells the humidifier when to turn on and off to maintain that level.
  • Excess Water Drainage: Any water that isn’t evaporated and turned into moisture for the air flows down the panel and is drained away. This prevents too much humidity, which could lead to condensation problems.

So, in essence, a whole house bypass humidifier adds moisture to the air circulated by your HVAC system by passing it through a water-soaked panel, with the whole process regulated by a humidistat to keep indoor humidity at comfortable levels.

What type of maintenance am I looking at if I buy a whole house bypass humidifier?

Maintaining a whole house bypass humidifier is essential to ensure it operates efficiently and safely. Here’s what typical maintenance might involve:

    1. Replace the Water Panel or Pad: This is the core part of the humidifier where water evaporates into the air. It should be replaced annually, as it can become clogged with minerals from the water, reducing efficiency. Some environments or heavy usage may require more frequent changes.
    2. Clean the Water Supply Line: This line can also get clogged with mineral deposits. An annual inspection and cleaning can prevent blockages that might impair the humidifier’s performance.
    3. Inspect and Clean the Drain Line: Since excess water drains out of the humidifier, you’ll want to ensure this line is clear. It’s a good idea to check it twice a year for any clogs or leaks.
    4. Check the Steam Distribution System: For systems that include a method of distributing steam or moisture more directly into the ductwork, an annual inspection can ensure it’s working correctly.
    5. Clean the Humidistat: The humidistat controls the operation of the humidifier based on your desired humidity level. Cleaning it annually helps maintain its accuracy and responsiveness.
    6. Look for Leaks and Seal Them: Inspect where the humidifier connects to your plumbing and ductwork. Any leaks should be sealed to prevent water damage and maintain system efficiency.
    7. Check the Bypass Dampers: These regulate air flow through the humidifier during different seasons. Ensure they’re operating smoothly and positioned correctly for the season—open for winter (when you’re using the humidifier) and closed for summer.

Whole House Bypass Humidifier Maintenance

Maintenance Task Frequency Notes
Replace water panel/pad Annually Essential for efficient operation
Clean water supply line Annually Prevents blockages
Check and clean drain line Twice a year Ensures proper drainage, prevents water damage

However, if you’re unsure about any aspect of the installation or want the peace of mind that comes with professional work, it’s wise to hire a specialist.


How does a bypass humidifier work?

Bypass humidifiers have a water panel installed in the supply plenum that adds moisture into the airstream when the humidistat reads that humidification is needed. Excess water gets channeled into a bypass duct so levels don’t get too high.

What does a bypass humidifier do in an HVAC system?

A bypass humidifier integrates into a home’s ductwork to add moisture during heating cycles based on the humidistat reading. This balances humidity levels in the living space.

Where is the best place to install a bypass humidifier?

Bypass humidifiers are typically installed high on the supply plenum or ductwork so gravity helps excess water flow into the bypass duct as designed.

What maintenance is required on a bypass humidifier?

You’ll need to replace the water panel or pad about every 1-2 years. Annual cleaning to flush out mineral deposits is also recommended.

Are bypass humidifiers energy efficient?

Yes, bypass technology only adds the specific amount of moisture needed, minimizing energy waste from over-humidifying.

How long does a bypass humidifier last?

With proper maintenance like replacing pads and cleaning, a bypass humidifier will typically last 5-10 years before needing full replacement.

What size bypass humidifier do I need?

Check manufacturer sizing guides based on square footage and desired humidity range. Also account for home construction, number of stories, and HVAC capacity.

How much does it cost to install a bypass humidifier?

Expect $500-$1500 total for the unit and professional installation. DIY installation can reduce costs but requires HVAC expertise.

Can I install a bypass humidifier myself?

Some DIY-friendly models from Aprilaire and Honeywell allow self-installation with proper HVAC knowledge. But specialized tools and skills are needed.

Do bypass humidifiers waste water?

Minimally. The bypass recirculates excess water rather than wasting it, and the humidistat only activates humidification when needed.

Tap Water in Humidifier? What’s The Issue?

If you have been doing any type of research on whether or not you can put tap water in a humidifier, you undoubtedly come across a lot of information to scare you.

A lot of sites make it sound like if you put tap water in a humidifier you will have committed the unpardonable sin.

Can You Put Tap Water in a Humidifier?

Using tap water in your humidifier is generally fine, especially if distilled water is not readily available. However, to ensure the longevity of your device and to maintain air quality, it’s important to clean your humidifier regularly and consider using distilled water when possible to minimize potential issues related to mineral buildup and impurities.

What Are The Issues Of Putting Tap Water In A Humidifier?

There are a few considerations to keep in mind to alleviate any concerns and to ensure optimal operation of your device.

    1. Water Quality Variations: The quality of tap water can vary depending on your location. In some areas, tap water might contain higher levels of minerals and impurities, which can lead to mineral buildup in your humidifier and potentially disperse these minerals into the air.
    2. Potential for White Dust: Using tap water, especially hard water, in ultrasonic humidifiers can result in a fine, white dust being emitted. This dust is composed of the minerals found in the water. While it’s not harmful to most people, it can be annoying and may settle on furniture and electronics.
    3. Cleaning and Maintenance: To reduce any negative effects of using tap water, regular cleaning and maintenance of your humidifier are crucial. This helps to prevent the buildup of minerals and the growth of mold or bacteria within the device.
    4. Filter Systems: Some humidifiers come equipped with built-in filters designed to reduce mineral deposits. If your humidifier has this feature, using tap water may be less of an issue, though you will need to replace or clean the filters regularly.
    5. Distilled Water as a Better Option: While tap water is generally safe, distilled water is often recommended for use in humidifiers because it lacks the minerals and impurities found in tap water. This can help extend the life of your humidifier, reduce the need for frequent cleaning, and prevent the emission of white dust.

Do these issues constitute some type of crisis that will keep your humidifier from operating? Not really.

And if you look around, you will find some humidifiers like Vicks that tell you to put tap water in your humidifier basin right in the instructions.

And like we pointed out before, if you are keeping up with a regular schedule of cleaning your humidifier with an acidic vinegar, you might not even notice these being issues at all.

And plus there are additives that you can purchase like Aquastick that will cut down the chances of mold becoming a problem with your humidifier for up to 90 days even with tap water.

The primary issue with any type of tap water  that you use in a humidifier is how many minerals and other particles that it contains.


What Water is Best for a Humidifier?

“Distilled water is the best water to run in a humidifier. Distilled water goes through a process that removes 99% of the minerals and sediment that you find in your usual tap water.”

Distilled water simply has less particles that can gum up a humidifier than any other type of water.

So if you want to give your humidifier the best chance for lasting longer, then make distilled water your choice for running inside of your humidifier.

You will find that it cuts down on the amount of humidifier dust that settles around your humidifier.

Does using distilled water in the humidifier mean that you do not have to clean your humidifier?

Not at all. Mold and bacteria will grow in distilled water that has been allowed to sit and become stagnant.

Maybe not as quickly as when you use tap water, but using distilled water in no way prevents the eventual bacteria in water over time.

What About Using Tap Water in A Warm Mist Humidifier?

And if you are using a warm mist vaporizer type humidifier then you already have a built-in mechanism for keeping mold and bacteria from becoming an issue with your humidifier.

These types of humidifiers raise the temperature of the water to a boiling point which will kill any bacteria in the water before it becomes airborne and inhaled by the user.

Humidifiers these days are pretty sophisticated. You can buy humidifiers that operate as both cool mist and warm mist as well as get them built with mold resistant plastic.

Top Fill designs take a huge amount of work out of using a humidifier because they do not require you to take the humidifier apart or turn the basin upside down to fill it with water.

So understandably, once you’ve made that extra investment into a humidifier with all the extra features, then you want to give your humidifier the best chance of lasting longer.

So using distilled water over tap water in your humidifier makes perfect sense at that point.

But the risk of putting tap water in a humidifier really doesn’t amount to a whole lot of excitement. And it’s up to you whether or not you want to deal with a little extra clean up.

Bottled Water in Humidifier?

Should you put a bottle of water in the humidifier if you don’t have any distilled?

Bottled water in a humidifier may be a little better than tap water because it does go through a little stricter of a purification process than tap.

But the minerals are not taken out of bottled water and since it’s the minerals that are the main issue with tap water, you’re only going to get a little bit of improvement using bottled water vs tap water.

How about using boiled water in the humidifier?

Boiling water will kill the bacteria or any type of fungal threat that could be present and water.

But the primary problem with boiling water then putting it into a humidifier is that boiling separates the sediment in the water and getting the water into the humidifier without getting the sediment in the humidifier along with it is going to be a little tough. Not impossible but tough.

Stream water seems like it would be a great solution for a humidifier but it probably has more minerals and sediment in it then tap water. And the likelihood of it already containing bacteria and fungus goes up a thousand percent.

bottled water for humidifier Summary

Should you use tap water in a humidifier?

“You can use tap water in the humidifier as long as you understand that the minerals and other particles in it can eventually reduce the output of the humidifier.”

And tap water generally creates more humidifier dust on and around the humidifier than other types of water.

But if you have a regular cleaning schedule for your humidifier that includes a good acidic vinegar, you may not ever notice that these are issues. source

But humidifiers can be quite expensive if you get the type with all the bells and whistles.

So understandably you want to put the best water possible in the machine to keep it working like new.

Distilled water is the best possible water for a humidifier because it does go through a process of removing the minerals and other particles as well as bacteria.

And it can reduce the amount of humidifier dust you see around your humidifier as well.

Right Out Of The Sink?
You can do it and it’s not the end of the world. But if you want the best water for your humidifier that will increase the chances of it lasting much longer, go with distilled water.

High or Low. Where to Place an Air Purifier for Maximum Effectiveness

Where’s the Best Place Put an Air Purifier?

The placement of an air purifier within a room can significantly influence how efficiently it’s able to clean the air.

You want it positioned for optimal air flow and circulation so contaminants are properly filtered out.

In general, the best placement is up high, away from obstructions, and facing the center of the room.

But depending on your specific needs and room layout, the ideal spot may vary. Certain locations can also lead to drawbacks, so it’s key to think through all angles.

Air Purifier Placement Guide

Room Type Ideal Placement Specific Tips
General Up high, facing the room’s center Consider height for maximum circulation, avoid obstructions
Bedroom High up, 5 feet from the floor Keep away from beds for less noise, target breathing zone
Living Room Central location, away from TVs Midpoint on wall for wide coverage, face towards seating area
Kitchen Near the stove top, raised up Avoid direct heat, keep away from sinks to protect filters
Baby’s Room High on the wall, away from crib Secure cords, point outlet away for quiet operation
Office Near the workspace, not facing directly Minimize noise for calls, keep away from computer vents
Basement Central, near stairs, elevated Prevent intake of musty air and radon, avoid walls for mildew

Key Considerations

  • Height: Up high for better circulation but consider ease of access for controls and filter changes.
  • Noise: Position away from sleeping or quiet areas, utilize quiet modes if available.
  • Pollution Source: Place close to localized pollutants but avoid direct contact with heat sources or water.
  • Avoid: Windows, closets, corners, and HVAC vents to prevent interference with air flow.

Air Purifier: Up High vs. Down Low

One of the biggest decisions is height – should you place the air purifier up high or down low? There are good reasons for both options.

Up High

Putting an air purifier up high, around 5-6 feet off the ground, is generally the recommended placement. Mounting it at upper wall height allows for maximum air circulation throughout the room. This enables the purified air to more easily reach all corners of the space.

Situating it high up also keeps the air intake away from floor-level contaminants and dust. Air near the ground tends to be more stagnant and laden with allergens that have settled out of circulation. An purifier positioned up top will breathe cleaner air to filter through its system.

Pros of High Placement:

  • Enables air to circulate better across the room
  • Prevents intake of floor-level particles
  • Out of reach of pets and children

Cons of High Placement:

  • Harder to access controls
  • May require mounting hardware
  • Strain to change filters

Down Low

While up high is ideal, some situations call for placing the purifier lower to the ground. This may be the better option for smaller rooms where airflow is less of a concern. A lower position also makes it easier to access the controls and change out filters when needed.

If you want the unit closer to a localized source of pollution like cooking smoke, pet areas, or a smoker in the house – a lower spot can help draw in and filter those ground-level contaminants before they spread.

Pros of Low Placement:

  • Easier to access controls/filters
  • Can better target ground-level pollutants
  • More stable if not wall mounted

Cons of Low Placement:

  • Reduced air circulation
  • Intake of more dust and allergens
  • Pet hair and child fingers more likely to block

Optimal Positioning by Room

Where you situate your air purifier will depend on the specific room it’s used in. Here are placement tips tailored for different rooms:


In bedrooms, aim to position the purifier high up, at least 5 feet from the floor. This allows it to better circulate air through the breathing zone of the bed. Having it draw in less dust and dander also helps if you have allergies.

If noise is an issue, locate it farther away from the bed on the opposite side of the room. Some models have a sleep/quiet mode to run at night.

Living Room

For living rooms and open concept areas, central placement works best so the whole space benefits. If mounted on a wall, a midpoint spot will allow purified air to reach seating across the room.

If you have a television, keep it a few feet to the side or overhead to prevent blocking the screen. And aim to face it toward the room, not the wall.


In kitchens, having it near the stove top helps immediately capture and filter out fumes and smoke from cooking. For best results, place it no more than 3 feet away raised up on the counter or mounted to the upper wall or ceiling.

Just don’t position it directly above the stove where heat and steam can damage the filters. And keep away from the sink in case of leaks/splashes.

Baby’s Room

The optimal spot for your baby’s room is high up on the wall at least 3 feet from their crib. This prevents any chance of them interacting with the buttons or vent and safely circulates air in their breathing zone.

For the quietest operation, point the outlet away from the crib. And always keep cords secured and out of baby’s reach.


In a home office, position the purifier near your workspace to filter the air in your direct breathing area. Just be sure it’s not actively blowing into your face as that could dry out your eyes.

For conference calls, placing it a few feet behind you can help minimize noise. And keep it away from computers as the fans can suck in dust.


Musty basement air is no match for a properly positioned purifier. Place it centrally near the foot of the stairs to optimize circulation across the entire basement.

Raise it up on a platform or mount it high to prevent musty air and radon gas at floor level from being drawn in. Point any outward-facing vents away from walls to reduce mildew growth.

Avoid These Bad Placement Spots

While thinking through where to put your air purifier, also be aware of spots you’ll want to avoid. These placements can limit effectiveness:

  • Near a Window – Open windows can draw in outside pollution before the purifier filters the air.
  • Inside Closets or Cupboards – Obstructed spaces prevent circulation throughout the room.
  • Corner of the Room – Away from the central air flow and high traffic areas.
  • Face-Level Height – Blowing purified air right into your face is uncomfortable.
  • Behind Furniture – Blocked intake and outlet vents reduce performance.
  • Near HVAC Vents – Can disrupt centralized airflow from furnaces/AC units.

FAQs on Air Purifier Placement

Should an air purifier be close to a window?

It’s better not to place an air purifier close to an open window as this may draw in additional outdoor allergens and pollution before the unit has a chance to filter the air. Keep it a few feet away.

Where should I put an air purifier in a small room?

In a smaller room, you can position it in the center against one of the walls as opposed to mounting it high up. This will allow it to better reach all corners of the space.

Can I put an air purifier on the floor?

It’s better not to place it directly on the floor, as this can kick up more dust, pet dander, etc. Raise it up on a platform or table at least a foot off the floor for cleaner air intake.

How close should an air purifier be to the source of pollution?

If trying to filter smoke, chemical fumes, or other localized pollution sources, place the purifier within 3 feet when possible so it can immediately capture those contaminants.

Should I put an air purifier near my AC vent?

It’s best not to position it right next to HVAC vents as this can interfere with the centralized airflow. Keep it a few feet away so air can circulate properly.

Where should I place an air purifier in an open concept home?

For an open concept room, central placement in the open living space is ideal so it can reach all surrounding areas. Elevated wall mounting works well to take advantage of air circulation.

How can I reduce noise from my air purifier at night?

Look for models with a sleep/quiet mode and aim the vent away from beds. Placing it on the opposite side of the room from beds can also reduce noise disturbances.

How do I know if my air purifier is in a good spot?

You’ll get the most efficient air filtration when able to feel a gentle airflow across the room. Visually check that vents aren’t blocked by objects. And monitor noise/light levels based on room activities.

Where should I place an air purifier in an elderly person’s room?

For an elderly person’s room, an upper wall-mounted location about 5 feet high is ideal to circulate clean air without creating a draft. Position it away from beds for noise reduction and near seating areas.

Can air purifiers be mounted on the ceiling?

Most air purifiers are designed to sit on the floor or mount to walls, but some models can attach to ceilings. Ensure it’s rated for this and check for any special mounting brackets needed.

Key Takeaways on Placement

Optimizing your air purifier’s position takes a bit of thought, but can really maximize its cleaning capabilities. Keep these tips in mind when finding the ideal spot:

  • Up high positioning around 5-6 feet enables best circulation.
  • Central locations allow reaching the entire room.
  • Keep away from windows, corners, vents and other dead zones.
  • Face the outlet toward the room’s center.
  • Adjust placement if too noisy for sleeping areas.
  • Target ground-level contaminants when needed.
  • Consider room size and layout limitations.

Take a moment to think through the options and experiment to find the best arrangement for your space. With smart placement and consistent use, your air purifier will keep your indoor air fresh and clean.

  • Who Needs It: Ideal for those with allergies, asthma, or anyone who wants to reduce the amount of indoor air pollution in their living spaces.
  • Key Features: Look for HEPA filters for the best particle removal, and consider activated carbon if reducing odors is also a priority.

Air Coolers: The Desert Oasis in Your Living Room

Now, picture a mirage in the desert, an oasis where water brings a refreshing coolness to the scorching heat. That’s the essence of an air cooler, using the natural process of evaporation to cool the air.

  • What They Do: Air coolers, also called swamp coolers, use water-soaked pads and a fan to evaporate water, which cools the air in the process. It’s a simple, energy-efficient way to bring down the temperature in dry climates.
  • Who Needs It: Best suited for those in hot, dry areas where the added humidity can be a comfort rather than a nuisance.
  • Key Features: Portability and low operating costs are significant plus points. Some models might include additional features like dust filters, but they won’t replace an air purifier’s functionality.

Air Purifier: An appliance designed to clean the air by removing pollutants, allergens, and other harmful particles through a system of filters, improving indoor air quality.

Air Conditioner: A system that cools and dehumidifies indoor air using a refrigeration cycle, making it comfortable during hot weather. It can be central (for entire buildings) or unit-based (for individual rooms).

Dehumidifier: A device that reduces humidity levels in the air, usually for health or comfort reasons, or to eliminate musty odor. It works by extracting water from the air and collecting it in a tank.

Diffuser (Aromatherapy Diffuser): Used primarily for distributing essential oils into the air for aroma and therapeutic benefits, some diffusers also function as small humidifiers.

Fans: Electric devices with rotating blades used to create airflow. They do not cool the air but can make a room feel cooler by moving air around and aiding in sweat evaporation on the skin.

Aluminum Tin Foil on Windows? What’s the Purpose?

Why do people put aluminum tin foil on Windows?

If Id have to be honest, the first thing I think about when I see a house that has the windows covered in aluminum tin foil is there must be something nefarious going on inside of the house. Drug dealers, crack cocaine, they’re doing something, I know it.

But that hardly makes sense. Why go to the trouble of attracting attention to yourself by blacking out the windows with aluminum foil if you were actually involved in criminal activity.

There are a lot better reasons that actually makes sense to cover your windows and aluminum foil.

Here are a few good reasons people put aluminum foil on Windows.

1. Darkens the room for sleeping

Aluminum foil is completely airtight without any way to see through it at all.

Putting tin foil on the Windows is an effective way to black out your room for sleeping.

There are plenty of professions and jobs that require people to work at night and sleep during the day.

And a lot of people, including myself need a dark room to be able to sleep soundly.

A dark room for developing film also requires complete blackness.

2. Does tin foil reflect Heat?

Easily the most common reason people put tin foil on the window is to reflect the heat coming in from the Sun.

This is not a new ideal.

Aluminum backed Radiant barriers are sold as insulation wrap for your attic to reflect the sunlight pounding the exterior the roof thereby cooling off the Attic and helping lower the energy bill.

Attic and wall insulation can also be purchased with an aluminum foil backing with the same ideal of placing the insulation with the foil side to the inside to reflect the heat.

NASA has long used this technique to to  reflect the Sun from transferring heat into the space shuttle.

Another example is a windshield shade for your car. Many times you we’ll see a shade that has aluminum foil backing on the outside to help reflect the Sun.

Putting foil on the windows follows this logic.

But aluminum foil on its own is not the most reflective of surfaces.

Adding the tin foil to a layer of cardboard before putting it in the window will create a much better  Radiant barrier reflector then tin foil alone.

And it’s an easy DIY recipe to help reflect and block the Sun from heating up your room.

3. Privacy

Most people just shut the blinds when they want privacy but if you need absolute privacy with no chance of anyone peering around the edges of your curtains, aluminum foil on the Windows is an effective way to block anyone from looking into your house.

Glare coming off the windows can not only be annoying because it reflects off of the TV or your computer screen making it hard to read or watch TV, it actually makes the sun feel like a magnifying glass peering down on you.

Aluminum tin foil on the windows, whether it be your taste or not, is an effective way of keeping glare from coming through your windows.

Does aluminum foil reflect the cold?

Aluminum foil does not keep things from getting cold. Tin foil is often used to wrap and store food in the freezer. If it reflected the cold, the food would not be able to freeze.
