A:Answer With Blueair products, you can breathe easy, with no increased danger from ozone. That’s because for 20 years, Blueair has conducted ongoing tests to ensure our air purifiers do not release harmful levels of ozone. The tests are carried out in accordance with the California Air Resource Board (CARB) certification program, the most stringent requirements in the world for air purifiers. Tested at Intertek, a CARB accredited test lab, Blueair products undergo a comprehensive series of tests to measure ozone emissions. In these 8-hour long tests, air purifiers are tested on high and low speed – with and without the filter installed. The Intertek facility features environmental chamber technology, the most trusted and proven scientific method available for testing to see if products produce ozone. As a result, all Blueair units meet the California Air Resource Board ozone emissions limit (<50ppb).
Additionally we have conducted ozone reductions tests that have shown ozone concentrations in the air directly after passing through Blueair’s filters to be lower than the ozone concentrations in the surrounding air.
