Not all air-cleaning devices are appropriate
for home use — some can be harmful to human health. The ARB
recommends that ozone generators, air cleaners that
intentionally produce ozone, not be used in the home. Ozone is a gas
that can cause health problems, including respiratory tract
irritation and breathing difficulty (Ozone and
Health).
In response to legislation,
Assembly Bill 2276 (2006, Pavley), the ARB has adopted a regulation
to limit the ozone emissions from indoor air cleaning devices. For
more information on the regulation, please click
here.

you select a safe and effective air cleaner are provided below. If
