Air Cleaner Testing and Certification

This page updated March 1, 2012

The Air Resources Board has adopted a regulation that establishes an ozone emission concentration standard, and requirements for certification, labeling and recordkeeping for indoor air cleaning devices that are introduced into commerce in California and used in occupied spaces. The amended indoor air cleaner regulation can be viewed here.



Frequently Asked Questions (FAQ)

A Frequently Asked Questions (FAQ) sheet has been developed to address the topics relative to the certification process for devices covered by the Air Cleaner Regulation. It is available in English, Korean and Chinese (simplified and traditional) at http://www.arb.ca.gov/research/indoor/aircleaners/translations.htm.
