Public Workshop to Discuss Amendments to the Regulation to Limit Ozone Emissions From Indoor Air Cleaners

The California Air Resources Board (CARB) invites you to participate in a public workshop on June 3, 2019 to discuss amendments to the indoor air cleaner regulation. The regulation was adopted by CARB in 2007 to limit ozone emitted from indoor air cleaning devices in order to protect public health.  All portable air cleaning devices sold in California must meet testing, labeling, and notification requirements in order to be certified by CARB.

At the workshop, staff will discuss proposed amendments intended to strengthen, streamline and update the regulation.  These include changes to the types of air cleaning devices that will be covered by the regulation, changes to requirements for certification, and modifications to the current list of industrial exemptions. This meeting is an opportunity to discuss specific amendments with stakeholders.

The workshop will be held at the time and location shown below:

DATE:                Monday, June 3, 2019
TIME:                9:30 a.m. to 12:00 p.m. PST

CARB adopted the indoor air cleaner regulation in 2007, setting a 0.050 parts per million (ppm) ozone emission concentration limit on portable indoor air cleaning devices that are manufactured, sold, or offered for sale for use in California, including those purchased through online sales. Devices must be tested by a CARB-approved laboratory in accordance with the type of device. The regulation includes specific labeling and notification requirements, as well as exemptions.  A fact sheet with compliance information for manufacturers of air cleaning devices is found online.
