Independent Certification for Ultra-Low Ozone Emissions
Today's consumers expect cleaner air, safer technology, and transparency from the brands they trust. The Intertek Zero Ozone Certification Program helps manufacturers meet that demand—offering independent, third-party certification that your air-cleaning device emits negligible ozone levels: no more than 0.005 ppm (5 ppb).
This certification goes beyond U.S. regulatory limits set by agencies such as the FDA, CARB, OSHA, NIOSH, and EPA, providing assurance that your product supports healthier indoor environments and meets the most stringent voluntary standards on the market.
Why Certify with Intertek Zero Ozone?
Intertek's certification confirms your product has been tested and verified to one of the lowest allowable ozone emission thresholds available in the U.S.—ten times lower than the limits set by CARB and the FDA.
Certification benefits can include:
- Testing/Verification from a Nationally Recognized Testing Laboratory
- Use of the Intertek Zero Ozone Certification Mark
- Listing in our Sustainability Certification Directory
- Increased consumer trust and competitive positioning in the market
Understanding Ozone Emission Limits
While ozone is naturally occurring, excessive indoor exposure can be harmful—especially to children, the elderly, and individuals with respiratory conditions. Here's how Intertek's certification compares to regulatory limits:
| Regulating/Testing Body | Maximum Acceptable Emission/Exposure Limit |
Mandatory Regulation |
| U.S. Food & Drug Administration (FDA) | .05ppm (50 ppb) | Mandatory to sell into USA |
| California Air Resources Board (CARB) | .05 ppm (50 ppb) | Mandatory for products sold in California, including online |
| Occupational Safety & Health Administration (OSHA) | .10ppm per 8 hours | Mandatory workplace exposure limit |
| National Institute of Occupational Safety and Health (NIOSH) | .10ppm per 8 hours | Recommended, not enforceable |
| EPA (NAAQS) | 0.070 ppm (70 ppb, ambient) | Mandatory |
| Intertek Zero Ozone Certification Program | .005 ppm (5 ppb) | Voluntary, but more stringent than all above |
Program Requirements & Maintenance
Intertek's Zero Ozone Certification program equates “Zero Ozone” as generating an ozone emission concentration of .005 ppm (5 ppb) or less. Certification renewal is required annually, and product reverification testing is required every 3 years. Testing must be performed by qualified laboratories and reviewed by Intertek for acceptance. The program fact sheet explains everything you need to know about the certification process, including ozone emission thresholds, accepted test methods, product eligibility, testing timelines, and annual renewal requirements:

Important: Even certified air-cleaning products must be used according to the manufacturer's instructions. Misuse can still result in elevated ozone exposure.
