How to Remove Ozone from Air?
Ozone, while beneficial in the upper atmosphere, is a harmful pollutant at ground level. Removing ozone from the air requires specific strategies depending on the scale and source of the ozone. For indoor air purification, several effective methods exist.
Using Air Purifiers
One of the most effective ways to reduce indoor ozone levels is using an air purifier equipped with the right filtration technology. Two primary options excel at ozone removal:
- Activated Carbon Filters: These filters chemically react with ozone molecules, breaking them down into less harmful substances. Many air purifiers utilize this effective method. [See references supporting activated carbon's role in ozone removal](https://www.osti.gov/servlets/purl/1050670, https://pubmed.ncbi.nlm.nih.gov/35972972/, https://hvac-talk.com/vbb/threads/174080-Ozone-Removal).
- Photoelectrochemical Oxidation (PECO) Technology: PECO technology uses a combination of light and catalysts to break down ozone molecules. This is a more advanced approach found in some higher-end air purifiers. See reference supporting PECO technology.
Important Note: Avoid air purifiers that generate ozone, as these are counterproductive and harmful to your health. See reference on hazardous ozone-generating air purifiers. The EPA also warns against ozone generators sold as air cleaners. See EPA reference.
Other Removal Methods
Beyond air purifiers, several other approaches can contribute to ozone reduction:
- Ventilation: Opening windows and doors increases air circulation, naturally diluting ozone concentrations. This is especially effective for quickly removing ozone from a small area. See Reddit discussion.
- HEPA Filters: While not directly targeting ozone like activated carbon, HEPA filters remove particulate matter which may be produced during ozone breakdown. Therefore, they can be a useful supplement, not a primary solution. See EnviroKlenz reference.
- Specialized Filters (e.g., Camfil CityCarb E): Some advanced filter systems, like the Camfil CityCarb E, offer combined particulate and gaseous contaminant removal, potentially including ozone. See Camfil reference
