How to Clean or Replace Range Hood Filters

Filters are the unsung heroes of your kitchen, silently trapping grease and cooking fumes before they turn into a sticky film on your cabinets. When these filters clog, your range hood struggles to move air, putting unnecessary strain on the motor and causing smoke to linger in your kitchen long after the meal is served. Maintaining them is a simple task that pays dividends in air quality and appliance longevity. A well-maintained filter system should be clear of debris and debris-free, ensuring the fan can pull air efficiently. Whether you are deep-cleaning a reusable metal mesh screen or swapping out a spent carbon filter, these steps will keep your ventilation system running at peak performance.

1. Access Both Filter Types. Locate the release latch on the edge of the metal grease filter and gently pull it downward. If your unit uses a charcoal filter, it is typically clipped onto the top of the grease filter or mounted directly to the fan motor; detach it by twisting or unclipping the housing.
2. Dissolve Years of Buildup. Fill your sink with very hot water and a generous squirt of heavy-duty liquid degreaser. Submerge the metal filters for 15 to 20 minutes to allow the grease to soften, then scrub with a stiff nylon brush and rinse thoroughly.
3. Prevent Motor Damage Now. Shake off excess water and place the filters on a drying rack or a clean microfiber towel. Ensure they are bone-dry before reinstallation to prevent moisture from damaging the fan motor.
4. Retire the Old, Install Fresh. Charcoal filters are disposable and cannot be cleaned. Compare your old filter to the new one to ensure a match, then lock the new filter into the mounting brackets on the fan housing.
5. Lock in Peak Performance. Slide the clean metal grease filter back into the slot, engaging the spring-loaded latch until you hear an audible click. Ensure it sits flush against the hood to prevent air leaks.
