Air purifiers
Air purifiers built on sealed mechanical filtration with real airflow numbers.
Air purifiers that rely on ionization, ozone, or fragrance can introduce new byproducts into the air they are meant to clean. Sealed mechanical filtration with published clean-air delivery rates removes particles without adding chemistry.
