Indoor Air Purifier (HEPA and ionizer types) — household safety profile

Moderate risk

Portable indoor air purifiers.

What is this product?

Portable indoor air purifiers. HEPA models are effective for particulates but don't remove VOCs or formaldehyde. Ionizer/electrostatic models generate ozone as byproduct — a respiratory irritant that can exceed California ARB limits. Some 'UV-C purifiers' generate ozone. Activated carbon filters adsorb VOCs but saturate quickly. Misleading marketing claims ('kills 99.9% of viruses') often not backed by real-world efficacy. Some units create formaldehyde from incomplete photocatalytic oxidation.
