Cooking is one of the biggest sources of indoor air pollution in a home. Searing a steak, frying, or roasting throws grease and ultrafine particles into the air you breathe while you eat. Moving that air out — and cleaning what's left — is the fix.
Two layers do the work: ventilation that pulls cooking air outside, and a HEPA purifier that captures the fine particulate that lingers. An air-quality monitor tells you whether either is actually keeping up.
