How to Clean a Range Hood Filter
Range hood filters (mesh or baffle style) trap grease from cooking vapours and become saturated over time — a clogged filter allows grease to pass through into the ductwork and fan motor, reducing effectiveness and creating a fire hazard. Clean every 1–3 months depending on cooking frequency.
Step 1: Remove the Filter
- Most mesh and baffle filters slide or hinge out from the underside of the range hood — no tools needed
- They are typically held by a clip or pull tab
Method 1: Boiling Water + Dish Soap (Most Effective)
- Boil a full kettle of water
- Place the filter in the sink and pour the boiling water directly over it — the heat immediately liquefies the grease, which runs off
- Apply dish soap to the filter surface and scrub with a soft brush
- Pour another round of boiling water over the filter while scrubbing — the combination of hot water and soap emulsifies and removes the remaining grease
- Rinse with hot tap water and allow to dry completely before reinstalling
Method 2: Dishwasher
- Many mesh filters are dishwasher-safe — place on the bottom rack
- Run on the hottest setting with dishwasher detergent
- Check the filter manufacturer's recommendation first — some baffle filters are not dishwasher-safe
Method 3: Degreaser Soak
- Fill the sink with hot water and a generous amount of dish soap or degreaser
- Submerge the filter and soak for 30–60 minutes
- Scrub with a brush and rinse
- Less effective than boiling water for heavy grease but good for regular maintenance cleans
