🚬 It’s not about the smoke

Clearing smoke from cooking is the 3rd most important job of your kitchen range hood.

Why it matters: The 1st job is clearing pollutants and the 2nd is removing moisture.

  • Every time you cook.

🔬 Zoom in: Pollutants

  • Every type of cooktop (gas, electric resistance, induction) heats your cookware, cooking oils and food enough to release VOCs (volatile organic compounds) and PM2.5 (fine particulate matter).
  • Gas ranges release additional pollutants like NO2 (nitrogen dioxide) and CO (carbon monoxide).

🔬 Zoom in: Moisture

  • Boiling and steaming release the most moisture increases indoor humidity.
  • But all cooking releases moisture from our food.

✅ For your Smart Homeowner list

  • Build a habit of turning the range hood on 1 minute before you start cooking.
  • Leave it on for 5 minutes after cooking — moisture that stays in the ducts needs to be cleared.
  • If you plan on renovating your kitchen, prioritize your range hood and avoid putting your cook top on an island where it’s harder to vent.
