The Association of Home Appliance Manufacturers (AHAM) is expanding its Directory of Certified Room Air Cleaners to include information on ozone emissions. AHAM's certification program currently tests the performance of room air cleaners in reducing tobacco smoke, dust and pollen. AHAM's certification program directory will provide participants the ability to indicate whether products comply with the American National Standard (ANSI) and Underwriters Laboratories (UL) safety standard 867 for ozone emissions.
Compliance with the ANSI/UL 867 ozone standard will be displayed as an additional column in AHAM's Directory of Certified Air Cleaners and will note whether each model meets UL's 50 ppb maximum ozone emission limit. A recent California law will limit portable air cleaner units sold in the state to a maximum 50 ppb in ozone emissions. This new feature of the AHAM Air Cleaner Certification program will appear in the November Directory.
The particulate reduction performance results of more than 40 brands have been tested through AHAM's Clean Air Delivery Rate (CADR) Room Air Cleaner Certification Program for nearly 20 years. he AHAM Directory will now include ozone emission information because of increased interest from the general public in ozone and air cleaners that produce ozone. Program participants will voluntarily submit ozone compliance information to AHAM for inclusion in the Directory.
More information on air cleaner performance technologies and AHAM's Room Air Cleaner Certification Program is available on the www.cadr.org web site. This site includes a list of manufacturers who have had their products Clean Air Delivery Rate performance verified through a third party laboratory. All AHAM certified products bear the CADR seal on the front of the product packaging. The CADR web site also includes a link to the U.S. Environmental Protection Agency where you can find more information on the effects of ozone generating air cleaners.
