Air Purifier (Ionizer / Ozone-Generating Type) — household safety profile

Moderate risk

Residential air purifiers including HEPA-only, ionizer, UV-C, photocatalytic, and ozone-generating types.

What is this product?

Residential air purifiers including HEPA-only, ionizer, UV-C, photocatalytic, and ozone-generating types. Ionizers produce ozone as a byproduct; some 'ozone generators' are marketed as air purifiers but produce ozone at levels exceeding EPA guidelines. Ozone at room concentrations that effectively remove pollutants (50-100+ ppb) exceeds the EPA health standard (70 ppb). HEPA-only purifiers produce no ozone.
