Both PECOAir and PECOAir+ are CARB certified and meet California's ozone-emissions requirements for indoor air cleaners. PECO uses a light-activated catalyst to break down organic pollutants. CARB certification is an emissions standard, rather than a promise of absolutely zero ozone or every possible byproduct.
Helpful Tip: Use the filters made for your model. Keep them unaltered and free of added oils, fragrances, or cleaners.
