Are you on the lookout for the best ozone free air purifier? Then, you have the right idea. With pollution and allergens often populating the air in this modern world, you need to use an air purifier at home or at the office. This ozone free air purifier review will help you find the best ones.
Why is there an emphasis on ozone-free? Some air purifiers, though well-meaning, produce ozone during operation. Ozone, also called trioxygen, can smell pungent. Sensitive noses will notice that something similar to chlorine, at least in smell, is in the air.
Having an ozone free air purifier is important for indoor air quality because it purifies the air you breathe. Smelling ozone is a warning. It means you need to do something about its release. Ozone can cause damage to your lungs. It can cause shortness of breath, chest pain, coughing, and many other symptoms that point towards a problem with the lungs. So, the presence of ozone defeats the purpose of an air purifier, which is to clear the air of irritants.
Air purifiers can easily improve the air quality at home. However, most of these technologies are achieved by generating a small amount of ozone into the air. Unfortunately, ozone has a terrible effect on human health. It stimulates the lungs in various adverse reactions. This article reviews some of the best ozone free air purifiers in 2021 and provides you with a detailed buyer’s essential guide to refer to when buying.
List of The Best Ozone Free Air Purifier in 2021
Why Ozone Free Air Purifier?
As mentioned earlier, most air purifiers on the market produce a small amount of ozone. This can have an adverse effect, which is more severe for people with allergies or asthma. When you use these ozone air purifiers all the time, even “safe” ozone production rates can be dangerous, especially for pets and children. A recent study found that long-term exposure to ozone is as harmful as smoking a pack of cigarettes a day.
The High-Efficiency Particle Arrestor (HEPA) air purifier has a fine mesh filter that filters out particles as small as 5 microns or one millionth of a meter, such as pet dander, pollen, tobacco smell, bacteria and Dust mite debris. Through the ultra-fine mesh, pollutants are extracted from the air, filtering out natural and healthy air, without irritating the lungs, making the air cleaner and safer. This is especially important when considering families and friends with asthma or allergies – HEPA filters eliminate discomfort and bring peace of mind.
Which air purifiers are ozone free?
Before we take a look at which air purifiers are ozone-free, we clarify a few things:
- HVAC filters do not fall under the air purifier category. So, why not? They may be filters, but they do not really remove the particles that must be removed. An HVAC filter lets the air swirl around in the room but does not remove air particles any better than a non-filtered fan. However, it does fare better in terms of cleaning the air.
- For a machine to be considered an air purifier, it must either destroy or remove the allergens from the air. HEPA filters are removers. So, they take the particles from the air. Sometimes, they also make use of activated carbon that removes gaseous particles. UV radiation cleaners and ozone generators fall under destroyers. The term “destroyers” takes on a more ominous meaning because they do pose more dangers than the average air purifier.
- Some air purifiers have ozone as their byproduct. Unfortunately, some air purifiers are meant to release ozone. So, be wary about advertising that the product uses. Some companies actually claim that the ozone is the one that does the air purifying. While this may be true to a certain point, these ozone emitters also produce potential health risks. A couple of examples of air purifiers that generate ozone are ionizers and ozonators.
With the above points clarified, you can now see that which air purifiers are ozone-free. Here are the types of ozone-free air purifiers:
- HEPA filters – This was discussed earlier. They remove 99.97% of all particles in the air. These particles can be as tiny as 0.3 microns. The best thing about HEPA filters, however, is that they do not release ozone. However, they may not be able to get rid of gaseous pollutants unless they also come with activated carbon. A HEPA filter also does not effectively get rid of odors.
- Carbon filters – Speaking of activated carbon, a carbon filter removes gaseous pollutants and VOCs. However, they may release some ozone and do no work as well on dust particles. So, it looks like a HEPA filter with activated carbon may work better.
- Photo Electrochemical Oxidation (PECO) – It is more efficient compared to PCO, which it may be mistaken for. It generates the right amount of hydroxyl radicals to annihilate pollutants. It uses UV-A light, which is much safer than the UV-C light.
So, when you are shopping for your ozone free air purifiers, you have above three main categories to choose from, depending on your needs. Take note that you may also opt for mechanical air purifiers which can provide you the safest protection out there.
How to pick the best ozone free air purifiers in 2021?

What To Consider When Choosing The Best Ozone Free Air Purifier
What do you want to remove?
Many people are not sure what particles to remove or what particles the air purifier can take away. Depending on the brand and model, the no ozone air purifier can remove the following impurities from the indoor environment.
Particles: These particles may include allergens such as pollen, dust mite feces, dust, mold spores, and pet dander.
Smell: Everything from cooking smell to old smoke and pet smell.
Chemical Substances and Volatile Organic Compounds (VOC): They are “released” by certain solids or liquids and are common in the home. Some of them are considered harmless, such as food containing volatile organic compounds. However, some of them have a negative impact on human health, such as formaldehyde and benzene. You can find VOCs in solvents, some household paints and cleaning products. They may also be deflated by furniture such as memory foam mattresses, carpets and MDF products.
Bacteria and viruses: These are self-explanatory. They may be trapped in certain filter types or destroyed by air sterilizers.
Usually, air purifiers without ozone are judged according to some features. Here are a few that you may consider when choosing one for your home or office space:
Air purifiers without ozone may come with certifications, such as an Energy Star logo. An Energy Star product can save you up to 40% in electricity use. Moreover, an Association of Home Appliance Manufacturers (AHAM) Verified Seal may also show that the product has passed the test in clean air delivery rates (CADRs).
While an air purifier may be useful, you may not like a product that makes a lot of noise. Many ozone free air purifiers contain a fan so a small amount of noise is generated. Some are very quiet, or completely quiet like Airfree devices. A normal conversation is about 50Db. If you are sensitive to noise or want to use an air purifier in your bedroom, you may wish to choose an ozone free air purifier that is as quiet as possible. An air purifier with a 50-decibel rating makes a sound similar to that of a refrigerator. It has been tested at its low and high settings.
3. Room Size
This is an important point that is often overlooked. All air purifiers come with the recommended room size. Our recommendation is based on the rate of 3 air changes per hour, based on a standard ceiling height of 2.2m. This provides a comprehensive level of air cleaning and is consistent with the normal air flow in most rooms. The manufacturer’s recommendation can be higher or lower than this recommendation.
4. Replacement filters
Buying the no ozone air purifier is not the end of it. Air purifiers come with running costs, not just power consumption. Many devices require periodic filter replacement (usually about every 6 months to one year) to maintain effective work. Some are equipped with permanent, washable or washable filters. If your device does need to replace the filter, then you must stick to this to ensure that your ozone free air purifier is working properly. A dirty or clogged filter will prevent the air purifier from working at its maximum. You may even have to change the filters every three months if activated carbon has been incorporated. So, you must be familiar with how much replacement filter costs. Some filters can go for as low as $20, but others can cost in the hundreds. So, you need to balance the price and the features. You need something that you can use and maintain for the long haul.
Ozone free Air Purifier Frequently Asked Questions
1. Can ozone free air purifier get rid of mold?
Air purifiers cannot get rid of mold once it has already latched and grown on a surface. However, a HEPA-filtered air purifier can remove airborne mold spores from the air. You should still address the issue of the growing surface mold, as this will pose a short-term solution only.
2. Can ozone generators kill mold?
The claim states that they can kill mold. This is not worth it, however, because ozone generators also pose a continuous health risk long after the mold is gone.
3. Is it okay to leave air purifiers on at night?
As features such as Sleep Mode suggests, you can leave air purifiers on at night. By doing so, you can keep your air cleaner. Your air purifier can also monitor if there are any changes in the air quality at night time. However, this also means replacing your filters more often.

6. Should I run the HEPA air purifier continuously 24/7?
Yes, you should. In order to be truly useful, it is essential to ensure that the filter operates continuously. According to research, once the system is shut down, the indoor pollution level will return to the pre-filtration level.
7. How much do these systems cost?
