Cooking Emissions: The Indoor Smog Source
Searing steak, frying in oil, or operating a gas stove produces sudden surges of ultrafine particulate matter, acrolein, and nitrogen dioxide (NO2) that can push indoor AQI over 300 within minutes. Understanding the difference between exterior-vented range hoods and recirculating purifiers is critical.
An exterior-venting range hood with at least 300 CFM is the gold standard, physically exhausting combustion gases outdoors. If your home has a recirculating hood, supplement it with a nearby high-CADR HEPA purifier equipped with activated carbon.
