Underwriters Laboratories will partner with Air Quality Sciences, Inc. (AQS), an indoor air quality solutions provider for healthy indoor environments, to test and certify indoor air devices against an improved UL 867 ozone emission standard. The partnership between UL and AQS was created to
respond to manufacturers who must comply with a new regulation adopted by the California Air Resources Board (CARB) that limits ozone emissions from indoor air cleaning devices sold into California.

In 2006, the American Lung Association of California, Consumers Union, and the appliance industry sought to limit ozone emissions from indoor air cleaners (such as intentional ozone generators, ionizers, and electrostatic air cleaning devices) being sold into California. UL refined the UL 867 test method for ozone to assure the accuracy and repeatability of the test. To demonstrate compliance with the CARB regulation that is expected to become effective in October 2008,
manufacturers must have their products tested to the improved edition of UL 867 and certified by California within 24 months of the effective date; essentially by October 2010.
