Our verdict:
- Levoit EverestAir is my top pick. It combines speed, smart features and comprehensive protection.
- Levoit Core 300 is my budget-friendly option. It offers outstanding performance at a price point that’s hard to beat.
- Levoite Core 600S is the best ozone free air purifier for large spaces. It is affordable and among the fastest units we’ve tested.
Ozone is a highly reactive gas that can change the chemical makeup of air pollutants when the two come into contact. This gives it the power to neutralize pollutants and kill viruses, bacteria, mold and other biological contaminants.
However, according to the EPA, inhaling ozone, even in relatively low quantities, can cause
⚠️ Chest pain
⚠️ Coughing
⚠️ Shortness of breath
⚠️ Throat irritation.
The ozone generated by some air purifiers is less of an issue than it was 10-15 years ago. Regulations now limit the amount of ozone purifiers can emit, such as the California Air Resource Board [CARB] limiting any unit sold in California to 50 ppb (parts per billion) of ozone.
You should still be aware that ozone is a risk with some filtration technologies. HEPA and Activated Charcoal filters create no byproducts, so they are 100% safe. But don’t buy an ozone generator — they can only be used in empty rooms and should not be used as an air purifier.
To help you find the perfect ozone-free air purifier for your home, I have collated eight excellent mechanical-based units without ionizing or active filtration technologies.
Why You Can Trust Our Recommendations As part of our buying guides here at HouseFresh, we dive deep into the performance of every air purifier we recommend by using our own measuring equipment to test each unit. We aim to help you cut through the marketing hype and find the right air purifier for your home. If a unit is no good, we will tell you. We have no ties with manufacturers and air quality brands. This is our testing process: 1️⃣ We create particulate pollutants by filling the air with thick incense smoke. We turn on the air purifier at its highest fan speed and use our PurpleAir Touch Indoor Air Quality Monitor to record how long it takes for PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 particles to be cleaned from the air. 2️⃣ We plug the air purifier through an electricity usage monitor and track energy consumption when running the unit across the different fan speed levels. 3️⃣ We use a sound level monitor to measure noise levels when running the air purifier at its lowest and highest speeds. |
Using all this information, we can compare air purifiers directly and choose the best ones. These options will remove common indoor air pollutants from your home while avoiding the release of chemical byproducts like ozone into the air.
To ensure our selection is up to the task, we’ve meticulously considered these four key factors:
✅ CADR (Clean Air Delivery Rate) – This tells you how much air an air purifier can clean per minute, giving you an idea of its efficiency. If the CADR is low, the purifier must work harder to clean the same air volume.
✅ Type of Filtration – Our recommendations all feature HEPA filters, which capture particles as small as 0.3 microns with 99.97% efficiency. However, HEPA filters aren’t as effective against gases, VOCs, or ozone, as activated carbon filters are. That’s why we also include options with different types of filtrations for addressing specific air quality concerns.
✅ Powerful Fans – An air purifier needs strong fans to effectively circulate and clean the air in a room, regardless of how good the filters are.

What to Look for When Buying an Ozone-Free Air Purifier
Not all air purifiers are inexpensive. Even the budget-friendly options usually need you to spend some money upfront. To help you choose the right one for your home, there are a few things to check in an ozone-free air purifier.
1. Type of Filters [HEPA + Activated Carbon]
For the best performance, HEPA (high-efficiency particulate air) filters are considered the gold standard in the industry. These filters are certified by the U.S. Department of Energy to remove 99.97% of particles and allergens as small as 0.3 microns.
HEPA particles can remove large particles, too, including smoke, pollen and mold spores suspended in the air. HEPA filters don’t help much with gas and VOCs and alone can’t remove ozone. However, unlike ionization filtration, HEPA technology does not release any chemical byproducts into the air. Go for H13 HEPA, H12 or H11, as these fit the sweet spot of particle removal and air flow rate.
Activated carbon filters, on the other hand, are very effective at ozone removal and other gasses and VOCs. Regarding activated carbon filters, the more carbon in the filter, the better. Choose an air purifier with HEPA and activated carbon filters for best results.
2. Clean Air Delivery Rating (CADR)
This is another critical factor besides the device’s filtration system. CADR, or clean air delivery rating, measures how quickly an air purifier can cycle the air in a given space through its per-hour filters.
By checking an air purifier’s CADR rating, you can tell how effectively the unit filters pollutants in a given room size. The higher the CADR rating, the more effective a device is in purifying air in a given room. For example, a unit with a 250 CADR rating produces 250 cubic feet of fresh air per minute to remove contaminants in that room.
3. Room Coverage
Another essential factor to consider when buying an air purifier is the device’s coverage range. Air purifiers aren’t created equal. Some units are best suited for classrooms and larger spaces, while others are good for household use.
As such, it’s essential to pick a product designed to purify the air in the space in which it will be used. Luckily, all air cleaners list their maximum square footage rating on their packaging.
4. Noise Level
You may want a quieter device depending on where you’ll be using your air purifier. Some air purifiers produce over 80 dB of noise while operating at full speed. Others are ultra-quiet and produce less than 60 dB at maximum speed.
If you want an ozone-free air purifier for your home, choose an option that doesn’t exceed 60 decibels. Such devices will not disrupt your sleep at night.
5. Smart Features
Last but not least, consider a device with smart features. Smart air purifiers have a programmable timer, quality monitoring and Wi-Fi connectivity. For instance, a unit with an air quality sensor automatically adjusts the fan speed after detecting a room’s air quality change.
If the device has a programmable timer, it will automatically turn itself on and off during specific times of the day, which can help ensure optimal energy consumption.
Common Questions About Ozone-Free Air Purifiers
🤔 Why should you deal with ozone sooner rather than later?
While ozone is incredibly effective at neutralizing air pollutants, like viruses, bacteria, and other contaminants, it also harms our lungs. According to the Environmental Protection Agency (EPA), inhaling ozone, even in relatively low amounts, can cause.
- Chest pain
- Throat irritation
- Shortness of breath
- Aggravation of asthma
🤔 What air purifiers don’t emit ozone?
As mentioned, devices with mechanical filters, like HEPA and activated carbon, don’t produce chemical byproducts. Air purifiers from these brands generally don’t emit ozone.
Air purifiers from Levoit, Smart Air, Dyson, IQAir and Honeywell only use mechanical filters and hence have zero byproducts, including ozone.
🤔 Do Blueair air purifiers produce ozone?
Blueair says their air cleaners are CARB certified, meaning they are safe and don’t exceed ozone emission limits. In our tests, we didn’t see any ozone production.
However, Smart Air detected significant ozone levels when the detector was next to the ionizer. Adding an ionizer is a great way to increase a unit’s CADR, which is what Blueair has done with its air purifiers. However, this also leads to the release of chemical byproducts.
🤔 What is the safest type of air purifier?
The safest air purifiers use mechanical filters like HEPA and activated carbon, which don’t release chemical byproducts.
🤔 How do I know if my air purifier emits ozone?
The quickest way to notice if an air purifier you have is exposing you to ozone is the smell. It will generally have an antiseptic odor. Also, check out the surface surrounding the air purifier. If it is dusty, there’s a high chance it’s emitting ozone.
Another good indicator is the lighting on the unit. Ozone-emitting purifiers tend to have a blue light coming off it.
🤔 Are all ionizers dangerous?
Not at all. Many of the ionizers used by companies like Blueair, Coway and others just use mild ionizing functions to improve the air-cleaning performance of the HEPA filter.
We have tested these units with ozone detections and have not seen any ozone detectable.
But we still know that some people have sensitivities to ionization, so we created this list of units that we can say 100% have 0 ozone created.
🤔 Do UV lights create ozone?
Demand for UV lights has recently risen as we look for effective ways to disinfect the air and surfaces around us. As some air purifiers come with inbuilt UV lamps, this may seem like an excellent way to kill bacteria or viruses in your home.
However, we typically find ultraviolet wavelengths of 185 nm are used in sanitizing and sterilizing systems, which are harmful to humans as this wavelength will emit high ozone concentrations. If the lamp is correctly coated or housed in certain glass, this should protect the user.
Although there have been instances of ozone leaking from the lamps and creating a toxic atmosphere if used in an enclosed space, we recommend avoiding UV purification.
🤔 Can an ionizer make you sick?
Ionizers work by electrostatically charging airborne pollutants within your space. Once charged, the particles become easier to remove with your air purifier. However, during this process, they also release ozone as a byproduct.
While this can be trace amounts (depending on your purifier), inhaling ozone concentrations can cause respiratory issues and throat irritation. It’s best to research any purifier before purchasing it to see if and how much ozone is emitted through its use.
We recommend avoiding ionizers entirely for those of you with asthma or other respiratory conditions.
Wrapping Up
Although many ozone-related air purifiers work to kill harmful chemicals and diseases in the air, the production of toxic ozone makes them too risky to use in your home.
Thankfully, numerous products are available on the market for you to use. A good thing to do is always look at the type of filters used and go from there. It’s easier to narrow these things down when factoring in your needed room coverage, noise concerns, etc.
So, which from our list do you feel benefits you the most?
