How to Clean a Greasy Range Hood Filter — Fast, Effective Method

Why Range Hood Filters Get Greasy

Every time you cook, tiny particles of grease rise into the air. Your range hood filter traps those particles, but over time the mesh becomes clogged. A dirty filter reduces airflow, increases kitchen odors, and forces your fan to work harder.

What You Need

  • Boiling water
  • Baking soda
  • Degreasing dish soap
  • Soft brush
  • Large pot or sink

Step‑by‑Step: How to Clean a Greasy Range Hood Filter

  1. Remove the filter. Most filters slide or pop out from the underside of the hood.
  2. Boil water. Fill a large pot or your sink with very hot water. The hotter the water, the better it dissolves grease.
  3. Add baking soda and dish soap. Mix in 1/4 cup baking soda and a generous squeeze of degreasing dish soap.
  4. Soak the filter. Submerge the filter for 10–20 minutes. You’ll see grease begin to lift off the metal.
  5. Scrub gently. Use a soft brush to clean the mesh. Avoid bending the metal.
  6. Rinse thoroughly. Run hot water through the filter until all residue is gone.
  7. Let it dry completely. Air‑dry the filter before reinstalling it to prevent moisture buildup inside the hood.

How Often Should You Clean It?

  • Light cooking: Every 2–3 months
  • Daily cooking or frying: Monthly
  • Heavy grease use: Every 2–4 weeks
