Do I need an Air Purifier or Humidifier for Sinus?

  Sinus pain is caused by inflammation in your sinus cavities. A cool mist humidifier can help sooth your sinuses and give you some much needed quick relief. 

 But a good air purifier will filter out as much as 99% of the germs and bacteria, which could be the reason you are having problems with your sinuses when you are in specific area in the first place.

In other words an ounce of prevention is worth a pound of cure.

Whenever I got into the air purifier business I did not even know what an air purifier was or what it did, only that I was looking for something to sell.

Through a MLM home business opportunity I was introduced to an air purifier that used photocatalytic oxidation to eliminate almost any kind of indoor air pollution.

And if you could stand the smell of ozone, that machine was awesome.

I thought, what an opportunity to help people alleviate the constant issues they have with sinus and allergies.

I mean everyone i know has problems with sinuses and breathing practically,

and providing an answer for those issues could provide me with an excellent business.

What I found out was that not only did I not know what an “air purifier” was but that not very many other people did either.

20 Years down the line and people still ask me if I’m still selling my HUMIDIFIERS. 

That is one of the points of this article.

These air devices or not something people think about everyday and why should they?

I found that a lot of people do not know the difference between air purifiers and humidifiers , dehumidifiers and Air conditioners.

Again, why would you need to know until you’re having a problem that requires you to get that knowledge?

So if you have sinus problems and you are looking for a device to help you feel better,

then you may be trying to figure out whether or not the air purifier is what you need or a humidifier.

 

There is so much confusion when it comes to colds and allergies.

For instance, you will hear that you need humidity to breathe when you have a sinus infection,

But you will also hear that mold and dust mites thrive in humid conditions.

And that Dust mites and mold spores are allergens and allergens cause sinus inflammation.

Confused yet?

Humidity or No humidity?

Truth is if you didn’t have humidity it would be way too dry and you would suffer from nosebleeds, sinus pain, and dry throat and you would be miserable.

But If you have too much humidity then the air is too thick and host more allergens clogging your sinus cavities, making it hard to breathe and you will be miserable.

But regardless of whether the air is too dry or The air is too wet, if the air quality is poor you are going to be miserable.

lol.

So which is it?

A humidifier will add humidity to the room when the air is too dry.

A Dehumidifier will take humidity out of the air when the air is to wet.

But regardless, it is the pollution in the air that is the culprit.

So unless you do something to help eliminate the allergens,

like dust mites and dander, mold spores and pollen, bacteria and germs, 

you are only asking to keep repeating the same issues you have with sinus infections and allergies over and over.

What type of air purifier do I need for sinus relief?

An Air purifier that has a true HEPA filter and a carbon filter is the best way to go in most small rooms, bedrooms, and living rooms.

HEPA filters will filter out pollutants of small is .3 microns which is over the top when you’re talkin about filtering out allergens.
Any gas or chemical allergenics will be captured by the carbon filter.

  Many air purifiers come with on board air monitors give you a continual update on the air quality in your house.

A very handy benefit when you are coming into pollen season or if you have introduced something new in the house that is making you tear up and sneeze.

Another type of air purifier that will help with the continuing issues with sinuses and allergies is the in duct air purifier.

This type of air purifier will require you to have central heat and air installed in your house or building.

The ideal Behind These air purifiers is that much of the allergens that are being circulated around the house are coming from your air handler itself.

The reason is, not only does your HVAC system provide a excellent breeding ground for mold,
it will also pick up other allergens and circulate them the house whenever the unit is running.

Placing the in duct air purifier inside the plenum of the central heat and air system will clean the air,

Before it gets into the house and clean the air that it is being picking up and circulating through the vents.

These are purifiers typically use photocatalytic oxidation or plasma ionic.

Since these are purifiers do not typically have any type of air monitoring capabilities,

it only stands to reason that installing an air qualty monitor in the house will help you keep track of air quality in your home.

Another monitor that you can buy that will help you reduce indoor air pollution,

and help you keep an eye on the wear and tear of your machines is a humidity monitor or the technical term hygrometer.

Humidity will not only help facilitate mold growth and dust mite growth.

It will also cause your air conditioner to run overtime, reducing the life of the unit.

What is a good indoor humidity level?

Most HVAC professionals agree that the humidity inside the home should be around 30 – 50%.

A dehumidifier will vacuum the moisture out of the air and create an environment that you can breathe in again.

Dehumidifiers are very handy when you are trying to use your basement as a living area.

Another off-the-wall question I sometimes hear is,

Can you be allergic to oxygen?

No you can’t be allergic to oxygen.

Oxygen is vital for living and is only one of the ingredients of air itself.

But your air can be full of contaminants that are causing you to have an allergic reaction.

Pollutants like pollen, mold spores, dust mites, dander, and all types of household chemicals may be present
in your air,

Making your oxygen seem allergic.

A UV or ultraviolet light , when it is targeted directly upon it, can effectively destroy mold, bacteria and fungus.

But that begs the question, since there is no way to Target a UV light on air itself –

What is the Purpose of a UV Light on a Air Purifier?

UV light is used in air purifiers to destroy pathogens in the air stream by using ultraviolet in three different ways including:

1. Targeting and destroying germs that are living on the Hepa filter.
2. Targeting it on the source of the mold in an HVAC. Coils, drip pans, etc.
3. Targeting it on a catalyst to cause a photocatalytic oxidation reaction of ions.
4. They will also kill any pathogens that happen upon the UV light bulb.
   
   

When I think about a UV light, it reminds me of being a young boy sitting in a barber’s chair.

The reason is that the barber always had a glass canister with a blue light in it,  sitting on a shelf behind him.

I didn’t know it back then, but that blue light was a ultraviolet lamp that he was shining on his Combs and scissors to keep them disinfected.

There are many more applications for ultraviolet light such as-

• keeping your aquarium clean
• sterilizing surgical equipment
• bug zappers
• tanning beds
• and even killing fungus in your shoes

And that’s a short list.

But Each One of These Relies on the UV Light Being Targeted Directly Upon Its Subject.

 But in the case of air purifier, You are simply not going to get air to sit in front of a disinfecting bulb and wait there for the pathogens in it to die. So that’s why when cleaning air with UV,  you either have to capture the pollution and aim the light on it. Or you have to aim it at the source of the pollution before it enters the air stream. 

HEPA UV Air Purifier

A HEPA UV air purifier works by drawing air into a HEPA filter with a  UV light aimed at the filter to destroy the germs or bacteria that are being trapped in the filter.

Otherwise without the UV in place,  the germs and bacteria can remain alive on the filter.

The Ultraviolet lamp also helps to disinfect the air as it passes through, providing extra elimination of airborne pathogens.

UV Light HVAC Furnace Air Purifier

The purpose of placing UV lights in your central heat and air conditioning (HVAC),

is to eliminate the production of of mold spores before they get a chance to become a problem,

And populate your ductwork,  spreading through your airstream via the vents.

The environment inside your furnace or HVAC,  because of moisture and the absence of light are an ideal climate for mold to grow.

Placing UV lights to target areas like drip pans and condensation coils inside the unit can keep mold from producing and ever becoming a problem.

Photocatalytic Oxidation (PCO)

Another way that UV is used in air purification is Photo catalytic Oxidation.

PCO targets the UV-C  on a hydrated catalyst composed of metals, primarily titanium oxide.

The result of this is the creation of hydrogen peroxide ions among other types of ions.

Hydrogen peroxide ions are essentially the gas form of hydrogen peroxide solution. The same stuff you put on a cut or abrasion for disinfection.

Since these air purifiers disperse ions in the millions, they can not only be considered an air sanitizer, they will sanitize the surfaces around the air purifier to.

Photocatalytic Oxidation is known to be very effective at reducing germs and bacteria. It is also one of the best ways to eliminate airborne mold spores.

This makes it another ,and a more efficient way to  purify the air inside of your central heat and air conditioning unit.

These induct UV air purifiers typically install into the plenum or supply air vent of the furnace – AC.

Can UV Air Purifiers be Dangerous?

Since the UV used in air purifiers is typically in the UV- C spectrum, it is very destructive to organisms, and that can include your eyesight.

For that reason it is imperative never to stare at the UV light and place the air purifier we’re children or not capable of staring at it either.

For professionals who have to deal with UV, there are professional goggles, gloves, and clothing,  you can purchase.

UV lamps also contain mercury. The amount of mercury in a light bulb is minimal what should it break, you should take care cleaning it up and make sure to dispose of the remains safely.
The truth is you are much more likely to get mercury poisoning from eating fish then breaking a UV bulb.

Other types of UV include  UV – A and the UV – B

UV- A is the wavelength responsible for getting a tan. Though it can be responsible for premature wrinkles on your face, it the least harmful of all UV wavelengths and exist in our everyday life. It is also manufactured for use in tanning beds.

UV- B ultraviolet is the type of UV wavelength that they warn you about on the evening news. This type causes sunburn and blistering on the skin. Skin cancer can also be a result of being exposed too long to UV-B.

Tanning beds sometimes combine UV-B with UV-A to get a faster tanning effect. Though it obviously doesn’t stop people,
It is hardly worth it to risk getting skin cancer for a quicker tan.

UV-C is the most harmful. Though it doesn’t naturally enter the Earth’s atmosphere because of the ozone layer, It is the wavelength that is manufactured the most because of its capacity to kill germs and destroy organisms.

UV-C also creates ozone as a byproduct.

Ozone is also very destructive to organisms but it can be destructive to your lung tissue also if you or exposed to it long enough.

 When using UVC lights or PCO in the central heat and air system, Ozone does not pose a problem at all because of the rate at which it dissipates. 

 

But stand-alone UV air purifiers can run the risk of creating too much ozone in a square space if the wrong size UV air purifier is not used in the appropriate space.

In other words, an UV air purifier that is completely safe in a large living space would be completely Overkill in a bathroom or small bedroom.

A good analogy for ozone is bleach. You can douse bleach into a bathroom and kill everything in there but you will not be able to go in there for quite a while.

Same with ozone. Too much in a small area is a hazard.

Since there is no way to regulate how people use ozone,

Or ensuring that people are using the right size air purifier in the designated square space,

Air cleaners that manufacture ozone,  including UV air purifiers that create too much ozone, have been outlawed in the state of California.

One of the main points of using an air purifier is to breathe easier in your home or office.

So it honestly it makes no sense to use ozone in your home as an air cleaner unless it is for remedial reasons like  mold clean-up and strong odor removal.

it should never be used in the vicinity of people,  pets or plants. and it is important to let it dissipate completely before utilizing the space again.

It is best to leave the ozone machines to the professionals and get it done right.

Summary.

UV is used in an air purifier by trapping air pollution into a HEPA filter and killing the pollution on the filter by targeting a UV lamp on it.

Or by placing UV germicidal lamps at the source mold spores inside your HVAC

And it is also used in Photocatalytic Oxidation to create a result air-purifying ions.

UV light is an excellent way of improving the air inside of your home or office.

For my money the best way of using UV for air purification is a PCO photocatalytic oxidation induct air purifier in your central heat and air system.

This method not only stops indoor air pollution before it gets started it also circulates sanitized air throughout your home or office building.

And also sanitizers any pollutants that are brought into the building before they spread to the rest of the house.

If your a pet owner like me, then you want to create the healthiest home environment possible for your companions.

Whether they be covered in fur or feathers, Minimizing exposure to things that could irritate the lungs or trigger allergies is important for people or pets.

 But what about the air our pets breathe every day?

Indoor air can contain many pollutants, allergens, and irritants that may go unnoticed but can affect respiratory health over time. This is where air purifiers come in.

Air purifiers can filter out many airborne contaminants, helping to clean the air in your home.

But is purified air safe for pets? Are there benefits to using an air purifier if you have cats, dogs, birds, or other pets?

In this article, we’ll explore the pros and cons of air purifiers for pets and provide tips on choosing the best model for your furry friends. Taking steps to purify the air can be one way to ensure your home supports your pet’s health and wellbeing.

Are air purifiers safe for pets?

Yes, air purifiers are generally considered safe for pets when used as directed. Air purifiers work by filtering out pollutants, allergens, and irritants from the air, which can benefit pets prone to allergies or respiratory issues.

Peace.

Can Air Purifiers Help with Cat Allergies?

Using an air purifier can be an effective way to reduce cat allergy symptoms for some people. The key is finding one that is designed to trap cat allergens specifically.

How Do Cat Allergies Work?

People with cat allergies are allergic to a protein called Fel d 1, which is found in cat dander (skin flakes), saliva, and urine. When a cat sheds or grooms itself, Fel d 1 particles get released into the air. When someone with a cat allergy breathes in these particles, it can trigger an allergic reaction.

Common cat allergy symptoms include:

• Sneezing
• Itchy, watery eyes
• Runny nose
• Nasal congestion
• Itchy throat
• Coughing
• Facial pressure and pain

How Air Purifiers Help

Air purifiers are designed to filter out pollutants, allergens, and particles from the air. To help with cat allergies, you need an air purifier that uses a HEPA filter.

HEPA stands for “high efficiency particulate air.” The key is that HEPA filters are designed to capture very small particles like cat dander that can trigger allergies.

A true HEPA filter removes at least 99.97% of particles as small as 0.3 microns. For reference, a human hair is about 50-70 microns wide. So HEPA filters can trap tiny cat allergen particles that would otherwise float right by standard filters.

Tips for Choosing an Air Purifier for Cat Allergy Relief

Here are some tips for picking an effective air purifier to reduce cat allergy symptoms:

• Look for a True HEPA filter – Make sure any model you’re considering uses a true HEPA filter, not just a standard HEPA-type filter.
• Pay attention to room size – Match the purifier’s recommended room size to the actual size of the room you’ll use it in.
• Aim for a high Clean Air Delivery Rate (CADR) – CADR measures volume of filtered air. Look for a high smoke CADR as that tests for fine particles like pet dander.
• Consider a model with an activated carbon filter – Activated carbon helps remove odors and gases.
• Pick a low noise level – Quieter models are less distracting.

It’s also best to run an air purifier continuously to keep air as allergen-free as possible.

Will an Air Purifier Completely Eliminate Cat Allergy Symptoms?

For some people with mild cat allergies, using an air purifier in rooms where they spend time with the cat can significantly reduce allergy symptoms. But air purifiers are not a cure-all.

Some people have such severe cat allergies that air purifiers, even high-end models, are not enough to prevent reactions. This is especially true if the person touches the cat and gets dander or saliva on their hands.

Air purifiers also won’t eliminate symptoms if the cat sleeps on furniture, clothing, or bedding and leaves behind dander and allergens. And they provide localized help – if you spend time in parts of the home without an air purifier running, you may still have allergy issues.

For severe cat allergies, medications or allergy shots may be needed along with thorough cleaning and air purification.

Should You Get an Air Purifier for Cat Allergies?

An air purifier can be a useful part of an allergy management plan. When combined with keeping the cat out of bedrooms, regular vacuuming and washing of linens, and laundering clothing after contact with the cat, an air purifier can help provide symptom relief.

Just be sure to choose one with the right specs for your needs. Focus on true HEPA filtration, appropriate room size, and a high Clean Air Delivery Rate. This can provide cleaner air and potentially less allergy suffering when living with a feline friend.

Frequently Asked Questions

Can air purifiers completely eliminate cat allergies?

No, air purifiers cannot completely eliminate cat allergies. They can help reduce airborne cat dander and allergens, but severe allergy sufferers may still react even with air purification.

Do I need a separate air purifier for each room with the cat?

It depends on your budget and the layout of your home. One purifier can work for adjacent rooms if you keep the doors open. Multiple units for separate areas of the home are ideal for the best coverage.

Where should I place an air purifier for cat allergies?

Focus on purifying the air in rooms where you spend the most time with the cat, like the living room or family room. Also put one in your bedroom since you don’t want the cat in there.

Can air purifiers help with pet hair and dander?

Yes, a HEPA air purifier can trap pet dander, hair, and other allergens so they don’t circulate in the air you breathe.

Should I run an air purifier all the time for cat allergies?

It’s best to run an air purifier continuously so it is always working to reduce allergen levels. You can use a timer or auto mode to save energy when you are not home.

Do I still need to vacuum and clean if using an air purifier?

Yes, you should still regularly vacuum and dust surfaces in rooms the cat accesses. Air purifiers filter the air but don’t eliminate allergens on surfaces.

Can air purifiers help with cat dander and urine smells?

Air purifiers with activated carbon filters can help reduce odors from cat dander, urine, and litter boxes. Models with UV-C light also help.

How often should I change the filter in an air purifier for pets?

It depends on use, but you should plan to change the HEPA filter at least every 6-12 months. Pre-filters can be vacuumed and changed more often if they look dirty.

The Bottom Line

Using a high-quality HEPA air purifier can be helpful for managing cat allergies. While not a cure, it can meaningful reduce allergy symptoms when combined with keeping the cat out of bedrooms, washing fabrics, and cleaning. Focus on HEPA filtration, room size, and high air delivery rates when choosing a model.

Do Air Purifiers work for pet allergies?

Air purifiers can be an effective tool for managing pet allergies. Here’s a detailed look at how air purifiers work and why using one can provide relief for those with pet allergies.

How air purifiers help with pet allergies

Pet allergies are triggered by proteins found in pet dander (skin flakes), saliva, and urine. When pets shed dander or salivate, the allergy-causing proteins can become airborne. Air purifiers work by filtering these allergens out of the air.

Air purifiers use different filtration methods to remove particles like pet dander. The most effective types for allergies are HEPA (high-efficiency particulate air) filters and activated carbon filters.

• HEPA filters: Remove 99.97% of particles 0.3 microns or larger. This includes pet dander and some allergens.
• Activated carbon filters: Absorb gases, odors, and microscopic particles like pet dander through chemical adsorption.

By continuously filtering the air, air purifiers can significantly reduce the levels of pet allergens circulating in a home.

Benefits of using an air purifier for pet allergies

There are several benefits to using an air purifier if you have pet allergies:

• Removes pet dander from the air: HEPA and carbon filters capture airborne dander particles.
• Reduces allergy symptoms: Lower dander levels can reduce allergy symptoms like sneezing, itchy eyes, and runny nose.
• Makes pet ownership possible: Lets pet-allergic people live with pets more comfortably.
• Cleaner air: Improves overall indoor air quality by reducing dust, odors, and other pollutants.
• Portable: Smaller models can be moved to different rooms as needed.
• Operates continuously: Works silently 24/7 to constantly clean the air.

Tips for managing pet allergies with an air purifier

To get the most out of an air purifier for pet allergies, follow these tips:

• Choose a HEPA filter model to effectively capture pet dander.
• Select a large enough capacity for the room size to allow adequate air circulation.
• Place in the main living area, bedroom, or room where pets spend time.
• Run the air purifier continuously at the highest fan setting.

An In-Depth Guide to the Different Types of Air Purifiers

I. Introduction

Indoor air quality has become an increasing concern in recent years. The EPA estimates that indoor air is 2 to 5 times more polluted than outdoor air. Poor indoor air quality can lead to various health issues like allergies, asthma, and chemical sensitivities.

Air purifiers provide an effective solution for cleaning the air inside your home. They work by filtering out pollutants like dust, pollen, mold, bacteria, pet dander, smoke, VOCs (volatile organic compounds), and more.

There are several different technologies used in air purifiers:

• HEPA (High Efficiency Particulate Air) filters – Most common type of air purifier filter, can capture 99.97% of particles 0.3 microns in size.
• Activated carbon filters – Absorb gases, odors, smoke, VOCs, and chemicals.
• UV-C light – Uses ultraviolet light to kill germs like bacteria and viruses.
• Ionic filters – Generate negative ions to attract and trap pollutant particles.
• Ozone generators – Produce ozone gas to oxidize and destroy contaminants.

This guide provides an in-depth look at how each type of air purifier works, their pros and cons, and popular options available.

Type	Pros	Cons
HEPA	Removes 99.97% of particles; great for allergies	No gas/odor removal; filter needs replacing
Activated Carbon	Eliminates odors and gases	Doesn’t capture particles; filter needs replacing
UV-C	Kills mold, bacteria, viruses	Doesn’t remove particles or gases
Ionic	Inexpensive; no filter replacing	Limited particle removal; potential ozone
Ozone Generator	Not recommended due to health risks

II. HEPA Air Purifiers

What is a HEPA Filter?

HEPA stands for High Efficiency Particulate Air. HEPA filters are designed to remove tiny particles from the air that can be harmful to breathe.

Particles that are 0.3 microns or larger are trapped with 99.97% efficiency. For reference, a human hair is about 100 microns wide. Common indoor air pollutants in this size range include:

• Dust
• Pollen
• Pet dander
• Mold spores
• Bacteria
• Smoke particles
• PM2.5 particulate matter

HEPA filters utilize a dense mesh of randomly arranged fiberglass fibers. As air passes through, particles are captured and retained in the filter. This removes them from the circulating air.

Pros of HEPA Air Purifiers

• Proven effectiveness – Extensively tested to meet strict performance standards. Government agencies like the Department of Energy rely on HEPA filtration.
• Removes most common allergens – HEPA is excellent at trapping dust, pollen, pet dander, mold spores and other particulate allergens. This helps reduce allergy and asthma symptoms.
• No byproducts or emissions – HEPA filters simply capture contaminants without producing any ozone or other chemicals. They don’t generate any secondary pollution.

Cons of HEPA Air Purifiers

• Doesn’t remove odors or gases – HEPA filters cannot absorb VOCs, smoke smells, chemical fumes and other gaseous pollutants. Need added activated carbon filter for this.
• Can be noisy – The fans required to pull air through dense HEPA filters can generate noise levels of 50 dB or more on higher speed settings.
• Replacement filters are required – HEPA filters become clogged after 6-12 months depending on use. Replacement filters can cost $50 to over $100.
• Larger particles first – HEPA is least efficient at capturing the smallest particles between 0.1 – 0.3 microns. Larger particles tend to clog the filter first.

Popular HEPA Air Purifier Models

• Winix 5500-2 – This is a leading air purifier for allergy and asthma sufferers. It includes true HEPA filtration, washable pre-filters, and activated carbon for odors.

III. Activated Carbon Air Purifiers

What is Activated Carbon?

Activated carbon is a highly porous material made from carbon. It has an incredibly large surface area that allows it to absorb and trap gases, chemicals and odors.

The “activation” process expands the pores and increases the surface area dramatically, creating an adsorbent material. Activated carbon is used in water filters, automotive cabin air filters, and of course, air purifiers.

In air purifiers, a layer of activated carbon is added to filtration systems. As air passes over the carbon, the pores capture VOC gases, cigarette smoke, cooking odors, pet odors, paint fumes, and other airborne chemicals.

Activated carbon removes these gaseous pollutants that standard HEPA filters cannot. The carbon also helps neutralize odors by adsorbing the molecules that cause smelly air.

Pros of Activated Carbon Air Purifiers

• Eliminates odors – Excellent at removing cooking smells, pet odors, cigar and cigarette smoke, musty smells and other odors from the air.
• Absorbs gases & VOCs – Takes out fumes from adhesives, paints, pesticides, cleaners and other chemical sources. Reduces indoor air pollution.
• Quiet operation – Activated carbon filters have low air resistance so fans don’t need to work as hard. Units run more quietly as a result.
• Often combined with HEPA – Many air purifiers combine HEPA filtration with activated carbon. This gives you the best of both worlds.

Cons of Activated Carbon Air Purifiers

• Doesn’t remove particles – Activated carbon only filters gases and odors. To remove dust, dander, etc. it needs to be paired with a HEPA filter.
• ** eventual replacement** – The carbon’s absorption sites get filled over time and it stops working. Replacement filters needed every 6-12 months.
• Not effective for some VOCs – Doesn’t work well for formaldehyde and other small molecular VOCs. Significant sources may require dedicated gas absorber filter.
• Can release trapped odors – Gas molecules trapped in the carbon can escape back into the air later. Periodic regeneration is required.

IV. UV-C Air Purifiers

How Does UV-C Technology Work?

UV-C air purifiers use short-wavelength ultraviolet light to kill or deactivate microorganisms like bacteria, viruses, and mold.

UV-C radiation damages the DNA and RNA of these organisms, rendering them unable to reproduce or function. This creates a germicidal effect without the use of chemical biocides.

Air purifiers emit UV-C light into an internal chamber that the airflow passes through. This exposure kills mold spores, bacteria, viruses and other biological contaminants in the air.

Some UV-C systems also utilize titanium dioxide filters that are activated by the UV light. This catalyzes oxidation reactions that destroy VOCs and odors.

Pros of UV-C Air Purifiers

• Attacks biological pollutants – UV light has been proven effective at neutralizing mold, bacteria, viruses, and other living microbiological contaminants.
• No filter changes required – Since UV-C works by irradiation rather than filtration, there are no filters to replace. Reduces operating costs.
• Chemical free purification – UV purification is achieved without using ozone or other potentially hazardous chemicals.
• Odor reduction capability – Units with TiO2 filters also help remove VOCs and smoke odors as air passes through the UV chamber.

Cons of UV-C Air Purifiers

• Doesn’t remove particulate matter – UV light has no effect on dust, pollen, pet dander and other non-living particles. HEPA filter still needed for these.
• Exposure risks – Direct UV exposure can damage skin and eyes. The irradiation chambers must be shielded to prevent UV rays leaking out. Cheaper units may have inadequate shields.
• Limited air flow – The irradiation chamber and shields restrict airflow, reducing CADR ratings compared to HEPA-only air purifiers. Not suitable for large spaces.
• Bulb replacement – UV-C bulbs lose intensity over time and need replacement every 2-3 years to maintain effectiveness.

• Envion Therapure TPP240 – Compact UV tower unit good for smaller rooms. Has UV-C, HEPA filter, and optional ionizer.

V. Ionic Air Purifiers

How Do Ionic Air Purifiers Work?

Ionic air purifiers work by charging air molecules and pollutants with electrons using an electrostatic charge field. This generates positive and negative ions that are released into the passing air stream.

The extra electrons attach to particles like dust, dander, pollen, mold and cigarette smoke. This gives them a negative charge so they are attracted to the positively charged collection plates inside the air purifier.

This electrostatic process causes the charged particles to clump together and become large enough to be captured on the plates. Some ions exit the unit to attach to out-of-reach particles as well.

Pros of Ionic Air Purifiers

• Inexpensive – Ionic purifiers are one of the most budget-friendly options since they don’t require expensive HEPA filters. Lower operating costs.
• Silent operation – With no fans or mechanical filters, most ionic purifiers run completely silently.
• Ozone free – Many ionizers now use needlepoint ion generation which does not produce dangerous ozone gas as a byproduct. Look for “ozone free” models.
• No maintenance – Ionic filters don’t need replacement like HEPA filters. Just occasional cleaning of collection plates.

Cons of Ionic Air Purifiers

• Limited particle removal – Ionic purifiers only remove about 30% of larger particles and 10% of fine particles. Not effective enough to be a sole air cleaner for many situations.
• Dirty plates – Collection plates become coated with particles and need frequent cleaning to remain effective. Plates may need weekly cleaning.
• Potential ozone production – Poor quality ionizers, especially older ones using corona discharge, can generate hazardous levels of lung-damaging ozone.
• Charged particle emissions – Some negatively charged particles may get re-released into the room air instead of being collected. There are health concerns over effects of inhaling charged particles.

• Sharper Image Ionic Pro – Oscillating compact ionic air purifier with touch controls and PM2.5 particle sensor.

VI. Ozone Air Purifiers

What is Ozone and How Do Ozone Generators Work?

Ozone is an unstable toxic gas made up of three oxygen atoms (O3). While ozone exists naturally in the upper atmosphere, at ground level it is classified as an air pollutant.

Ozone generators produce ozone artificially using corona discharge or UV light methods. The strong oxidizing power of the O3 molecules destroys bacteria and odors. But it also damages lung tissue lining when inhaled.

Most health organizations recommend avoiding ozone generators since potential harms outweigh benefits. Ozone does not effectively clean and purge indoor spaces of pollutants either, as was once believed.

Pros of Ozone Air Purifiers

• Attacks odors – The oxidizing potential of ozone may have some effectiveness at removing stubborn odors that linger even after cleaning.
• Inexpensive – Basic ozone generators are cheap since they have no filters and few parts.

Cons of Ozone Air Purifiers

• Health hazards – Multiple studies have shown health risks of ozone, especially for children and those with asthma or respiratory conditions. Short term effects include chest pains, coughing, throat irritation and lung damage.
• No particulate filtration – Ozone does not remove dust, pollen, pet dander, mold and other common airborne particles.
• Ineffective pollution removal – Ozone has low reactivity with many chemicals like VOC gases. It does not cleanse rooms of pollutants as marketed.
• Property damage potential – Ozone can degrade rubber, plastic and fabrics, causing damage to belongings. Many materials are not ozone resistant.

Examples of Ozone Generator Air Purifiers

• Ozone generators are not commonly found anymore due to health concerns, but a few models still exist:
• EcoQuest Fresh Air – Uses coronal discharge to produce ozone. EcoQuest claims their “activated oxygen” process is safe but many health agencies disagree.
• OdorStop OS2500 – An industrial style ozone generator that creates very high ozone concentrations advertised to remove smoke odor. Too high for safe residential use.
• Airthereal MA10K-PRO – Despite marketing as an ionizer, it uses UV bulbs to generate ozone rather than the safer needlepoint method.
• Ecozone Ozone Generator – Among the most affordable ozone machines but puts out an alarming amount of ozone at up to 7,000 mg/hr.
