How to Clean a Stovetop Hood Fan Filter
Range hood filters are designed to trap grease so it doesn't build up in the ductwork and become a fire hazard — but that means the filter itself accumulates grease until it becomes fully clogged and useless. Most Toronto home cooks haven't cleaned their range hood filter in years. Here's how to do it in 10 minutes.
How to Remove the Filter
Most range hood filters either slide out from under the hood (there's usually a small tab to push or pull) or unclip from the housing. Turn off the range hood before removing. Hold the filter carefully — grease can drip from a heavily soiled filter.
Method 1 — Dishwasher (Easiest)
Many mesh-type filters (the most common type in Toronto homes) are dishwasher-safe:
- Place the filter in the dishwasher on its own or with other heavily soiled items
- Run on the hottest cycle with a heavy-duty detergent
- Allow to dry completely before replacing
Check your filter — if it's mesh (metal with small holes), it's almost certainly dishwasher-safe. If it's a baffle filter (long parallel ridges), it's also typically dishwasher-safe. Carbon/charcoal filters are NOT washable — they need replacement.
Method 2 — Hot Water Soak (Most Effective for Heavy Grease)
- Boil a full kettle of water
- Fill a sink or large basin with the boiling water and add 1/4 cup of dish soap and 2 tablespoons of baking soda
- Submerge the filter and let soak for 10–15 minutes — the hot water and baking soda dissolve grease far better than cool water
- Scrub with a stiff brush to remove loosened grease — it should come off easily
- Rinse under running hot water
- Allow to dry completely before replacing
Cleaning the Hood Interior
While the filter is out, wipe the interior of the hood with a degreaser spray and paper towels. The inside surface accumulates grease over time and benefits from cleaning every few months when you clean the filter.
Charcoal/Carbon Filters
Recirculating range hoods (those without an external duct — common in many Toronto condos) use carbon filters that absorb cooking odours. These cannot be washed and need replacement every 3–6 months. Check your model's manual for the specific replacement filter. A saturated carbon filter offers no odour protection.
How Often
- Light cooking (once daily): every 3–4 months
- Heavy cooking (multiple meals daily): monthly
- Visual check: when grease drips from the filter, it's overdue
