Air Cleaner Regulation (AB 2276)
In accordance with California Assembly Bill 2276 (2006, Pavley), CARB adopted an air cleaner regulation to limit the amount of ozone produced from indoor air cleaning devices, with the goal to protect public health. The regulation became final on October 18, 2008. Additionally, several amendments to the regulation received final State approval on September 10, 2010. During regulation implementation, manufacturers had three compliance dates to meet:
- By October 18, 2009, manufacturers were required to notify their distributors, retailers, and sellers about the regulation and provide copies of the final regulation to them, and to provide documentation to CARB that this has been accomplished.
- All air cleaner models marketed or sold in California after October 18, 2010 had to be tested and certified as required by the regulation. This included air cleaners sold via the Internet.
- As of October 1, 2012, all packaging had to show the required label printed on the package.
Manufacturers and distributors of air cleaning devices are responsible for becoming familiar with the regulation and meeting its requirements. CARB is currently in the process of amending the air cleaner regulation, but these changes have not gone into effect. Information about upcoming changes to the regulation can be found on the associated rulemaking webpage, which will be updated regularly.
