Easy15-30 minutesAppliances

A clogged range hood filter reduces ventilation efficiency and increases the risk of grease buildup near heat sources, creating a fire hazard. Cleaning your filter monthly is a simple maintenance task that any homeowner can complete in just 15-30 minutes without special tools or skills. Regular cleaning keeps your kitchen safer and helps your range hood work at peak efficiency.

What You'll Need

Supplies

  • Degreasing dish soap (Dawn or similar)($3-5)
  • Baking soda (optional for heavy grease)(optional)($2-3)
  • Clean dish towel or paper towels

Tools

  • Soft-bristled brush or old toothbrush
  • Plastic scraper or old credit card
  • Sink sprayer or kitchen spray bottle(optional)

Step-by-Step Instructions

1

Turn off the range hood and let it cool

Before removing the filter, ensure the range hood fan is completely off and the filter has cooled to room temperature. If you've been cooking, wait at least 5-10 minutes after shutting off the hood to allow any remaining heat to dissipate. This prevents burns and ensures your safety while handling the filter.

Pro Tip: Check that your stove is also off before starting this task to ensure complete safety in the kitchen.

2

Locate and remove the filter from the hood

Look up at the underside of your range hood to identify the filter frame. Most filters slide out or are held in place by clips or a release mechanism—consult your hood's manual if you're unsure. Gently pull or push the filter (depending on your model) until it slides completely free from the hood housing.

Pro Tip: Take a photo of how the filter sits before removing it, so you can reinstall it in the correct orientation.

3

Scrape off loose grease and debris

Hold the filter over a trash can and use a plastic scraper or old credit card to remove any large chunks of hardened grease from both sides of the filter. This preliminary scraping prevents grease from clogging your sink drain and makes the washing step much more effective. Work carefully to avoid damaging the filter mesh.

Pro Tip: A plastic dough scraper works great for this step and won't damage the filter like metal tools might.

4

Soak the filter in hot soapy water

Fill a bathtub, large sink, or plastic basin with hot water (as hot as your tap allows) and add a generous squirt of degreasing dish soap. Submerge the filter completely and let it soak for 15-20 minutes to loosen stubborn grease buildup. If your filter is very greasy, you can add 1/2 cup of baking soda to boost the cleaning power.

Pro Tip: Use your bathtub if you don't have a large enough sink—just rinse it thoroughly afterward to remove any soap residue.

5

Scrub the filter thoroughly with a brush

Remove the filter from the soapy water and use a soft-bristled brush or old toothbrush to scrub both the top and bottom surfaces, working the bristles through the mesh openings. Pay special attention to corners and edges where grease accumulates. Rinse under running water while continuing to brush until the water runs clear and the filter looks clean.

Pro Tip: A soft-bristled kitchen brush or vegetable brush is ideal—avoid wire brushes that can damage the filter mesh.

6

Rinse until water runs clear

Hold the filter under warm running water and rinse from the top side first, then flip and rinse the bottom side. Keep rinsing until no more soap bubbles appear and the water flows through the filter without any foam. You should see light shine through the mesh clearly when it's clean.

Pro Tip: Use your sink sprayer if available—the concentrated water pressure helps flush out trapped grease faster than hand rinsing.

7

Dry the filter completely

Shake off excess water from the filter over the sink, then set it upright on a clean dish towel or rack to air dry completely. Allow at least 30 minutes for drying, or place it in a warm area to speed up the process. Do not reinstall a wet filter, as moisture can damage electrical components or reduce effectiveness.

Pro Tip: Lean the filter against a wall at an angle to help water drain off completely and speed up drying time.

8

Reinstall the filter in the range hood

Once the filter is completely dry, slide it back into the range hood using the same orientation it was in before removal (refer to the photo you took earlier if needed). Make sure the filter is fully seated and any clips or fasteners are securely in place. Run the range hood briefly on a low setting to confirm it's working properly.

Pro Tip: If your hood has a grease indicator light, this is a good time to reset it according to your manufacturer's instructions.
