How to Clean Range Hood Filters (Degrease Kitchen Mesh Filters)
Time required: 20-30 mins (plus soak time) · Difficulty 1/5
A grease-caked range hood filter is a real kitchen fire risk — it can't trap grease effectively once saturated, letting it build up inside the hood and duct. Clean filters monthly if you cook often, especially with oil or on high heat.

Parts & Tools You'll Need
- Replacement Aluminum Mesh Range Hood Filter
- Degreasing Dish Soap
- Large Sink, Tub, or Bucket for Soaking
- Soft Scrub Brush
Step-by-Step Manual
- Remove the filters Most mesh filters slide out or release with a simple latch or push-button on the underside of the range hood.
- Make a hot degreasing soak Fill a sink, tub, or large bucket with the hottest tap water available, add a generous squirt of degreasing dish soap and 1/4 cup baking soda, and stir to dissolve.
- Soak the filters Fully submerge the filters and let them soak for at least 10-15 minutes to loosen baked-on grease.
- Scrub and rinse Scrub both sides of each filter with a soft brush to remove remaining grease, then rinse thoroughly under hot running water.
- Dry completely before reinstalling Shake off excess water and let the filters air dry fully (or towel dry) before sliding them back into the hood — reinstalling wet traps moisture and odor.
- Replace if cleaning no longer works If the aluminum mesh is bent, torn, or stays discolored and stiff even after soaking, replace it — a damaged filter can't trap grease effectively.
Frequently Asked Questions
Can I put range hood filters in the dishwasher?
Many aluminum mesh and stainless steel baffle filters are labeled dishwasher-safe by their makers, but check your hood's manual first. Run them on their own, upright, without heated dry if possible. Some dishwasher detergents can dull or darken aluminum over time, so a hand soak in hot water with dish soap and baking soda is the gentler option.
How often should I clean my range hood filter?
About once a month if you cook most days, especially with oil or on high heat. Light cooks can stretch it to every two to three months. A filter that looks dark, feels sticky, or drips grease is overdue.
Can I wash a charcoal range hood filter?
No. Charcoal (carbon) filters are used in hoods that recirculate air instead of venting outside, and they trap odors rather than grease. Water and soap ruin them, so they are replaced, not washed. Only the metal grease filters should be cleaned.
Should I use oven cleaner on aluminum range hood filters?
Avoid it. Most heavy-duty oven cleaners contain lye, which can corrode and discolor aluminum mesh. Hot water, a degreasing dish soap, and baking soda remove kitchen grease without harming the metal. Stainless steel baffle filters are more forgiving, but follow the maker's care label.
When should I replace a range hood mesh filter instead of cleaning it?
Replace it if the mesh is torn, bent out of shape, or still stiff with grease after a long soak, or if the frame no longer fits snugly in the hood. Measure the old filter's length, width, and thickness before ordering, since sizes vary by hood model.
