A typical home air purifier, especially one advertised for particles, is not established as an ozone-removal device. EPA guidance distinguishes particle filters from gas-adsorbing filters, and it warns that ozone generators sold as air cleaners should not be used in occupied spaces.
Why ordinary air purifiers may not remove ozone
Air cleaners work on different pollutants through different mechanisms. HEPA filters and particle Clean Air Delivery Rate (CADR) ratings address particles such as smoke, dust, and pollen; those claims do not show that a unit removes ozone. EPA describes gas filtration separately: its Guide to Air Cleaners in the Home advises choosing activated carbon or another filter designed for gases when gas removal is the goal. That general guidance does not establish ozone-removal performance for a particular consumer purifier.
For any claimed ozone-removal device, look for substantiated performance specifically for ozone, rather than inferring it from a HEPA label, particle CADR, or generic carbon-filter description. EPA does not certify or recommend particular air-cleaning brands.
Ozone generators are not ozone-removal devices
An ozone generator produces ozone; it does not make ozone a safe or effective way to clean occupied indoor air. The U.S. Environmental Protection Agency states: “Ozone generators sold as air cleaners should not be used in occupied spaces.” EPA also says these devices have little potential to remove indoor contaminants at ozone concentrations that do not exceed public-health standards. Ozone can harm health, and reactions between ozone and indoor chemicals can create other irritating or corrosive compounds. See EPA’s Ozone Generators that are Sold as Air Cleaners.

What to do if you are concerned about indoor ozone
Identify and reduce the source
Start by determining whether ozone is actually the concern and, where possible, reducing the source. Do not assume that a general-purpose purifier will address it.
Ventilate appropriately
EPA treats ventilation as one part of indoor-air management, alongside source control and air cleaning. The right approach depends on the situation; air cleaning alone is not a replacement for source control or ventilation.

Choose a cleaner for the pollutant it can address
For particles, compare particle-focused measures such as smoke, dust, and pollen CADR. For gases, check whether the unit has a gas-adsorbing medium and whether the manufacturer substantiates performance for the specific gas of concern. Neither particle CADR nor the presence of generic activated carbon proves ozone removal.
EPA’s Air Cleaners, HVAC Filters, and Coronavirus (COVID-19) explains that “Air cleaning may be useful when used along with source control and ventilation, but it is not a substitute for either method.”

How to compare air-cleaner claims
| Claim or feature | What it tells you | What it does not establish |
|---|---|---|
| HEPA or particle CADR | Particle-cleaning performance; CADR categories include smoke, dust, and pollen. | Ozone removal. |
| Activated carbon or other gas filter | The unit is designed to address some gaseous pollutants; EPA notes that enough activated-carbon material can be effective for gases. | Ozone removal by a particular consumer model unless ozone-specific performance is substantiated. |
| Ozone generator | The device produces ozone. | A safe or effective ozone-removal solution for an occupied home. |
| AHAM certification or CADR listing | A way to compare particle-cleaner performance for smoke, dust, and pollen. | EPA approval or certification of ozone-removal performance. |
EPA identifies AHAM’s room-air-cleaner certification program as a resource for comparing particle cleaners; it is not an ozone-removal certification. Use the rating only for the pollutant and performance category it covers.

Practical cautions
- Do not operate an ozone generator around people. EPA’s Residential Air Cleaners – A Technical Summary explicitly advises against using ozone generators in occupied spaces.
- Do not treat an “air cleaner” label, ionizer feature, HEPA filter, or particle CADR as proof that a device is ozone-free or removes ozone. EPA flags ionizers and some other technologies as potential ozone emitters.
- Do not buy generic activated-carbon filtration on the assumption that it removes ozone. Require ozone-specific, substantiated performance for that particular product.
