A range hood filter collects grease that can reduce airflow and eventually drip or smell when it becomes saturated. Before cleaning it, determine whether it is a washable metal filter or a charcoal cartridge intended for replacement.
Determine whether the filter is washable or replaceable
Metal mesh filters are commonly washable, while many recirculating charcoal filters are replaced when they lose effectiveness. Check the manual or filter part number before soaking a component that is not meant to get wet.
Degrease with hot water and a mild cleaner
Place the filter in a stable basin and use hot water with a compatible degreaser or hand dishwashing liquid. Let grease soften, then brush the mesh without bending it; avoid aggressive chemical mixtures.
Rinse until no cleaner residue remains
Soap or degreaser trapped in the filter can smell when the hood warms up. Rinse from both directions and inspect layered mesh because grease often remains between the layers.
Let the filter dry completely before reinstalling
Stand the filter upright until it is no longer dripping and is fully dry. While it is out, clean only accessible hood surfaces with power disconnected if the manual requires it; keep liquid away from the motor and wiring.
