How to Clean a Cooker Hood Filter – Simple Steps for a Fresh Kitchen

Ever notice your cooker hood coughing out greasy smoke or struggling to pull air? That’s usually a dirty filter. A blocked filter reduces suction, makes cooking smells linger, and can even become a fire hazard. The good news? Cleaning it takes less than 15 minutes and saves you money on professional calls.

Why You Should Clean the Filter Regularly

When you fry, grill, or bake, oil droplets get trapped in the filter. Over time those droplets turn into a thick gunk that blocks airflow. The result is weaker extraction, more steam on your cabinets, and a higher chance of grease buildup on the fan motor. A clean filter keeps the fan running efficiently, lowers your energy bill, and extends the life of the whole hood system.

Step‑by‑Step Guide to Cleaning Different Types of Filters

1. Identify your filter. Most hoods have either a metal mesh (aluminium or stainless steel) or a charcoal‑filled cartridge. Metal meshes are reusable; charcoal filters need replacement after a few cleanings.

2. Gather tools. You’ll need hot water, dish soap, a soft scrub brush or old toothbrush, a large bowl, and a towel for drying. For stubborn grease, add a splash of white vinegar or a few drops of degreaser.

3. Remove the filter. Most filters slide or pop out with a gentle pull. Keep track of any clips or screws; a quick photo helps you remember how it fits back.

4. Soak the metal mesh. Fill a basin with hot, soapy water and submerge the filter for 10‑15 minutes. The heat loosens baked‑on grease.

5. Scrub away the grime. Use the brush to work through the mesh. If you see thick spots, sprinkle baking soda on the brush – it acts like a gentle abrasive.

6. Rinse thoroughly. Run the filter under hot water until all soap disappears. Any leftover residue can quickly re‑attract oil.

7. Dry completely. Lay the filter on a clean towel and pat it dry. A wet filter can rust if it’s metal.

8. Re‑install. Slide the filter back into the hood, making sure it seats snugly. Turn the hood on low for a few seconds to confirm everything works.

If you have a charcoal filter, skip the soaking step. Instead, gently tap it to knock loose large particles, then vacuum the surface. When the charcoal starts to smell stale (usually after 3‑6 months), replace it with a new one.

Tip: Keep a small bucket of hot, soapy water under the sink. That way you can clean the filter while the water is still warm from your dishes.

When to clean? As a rule of thumb, clean metal filters every month if you cook a lot (especially frying). For light cooking, every 2‑3 months is fine. Charcoal filters need changing every 3‑6 months, depending on usage.

Notice any of these signs? Reduced suction, louder fan noises, or a lingering greasy smell? Those are clear clues that the filter is overdue for cleaning.

Keeping the filter clean is a tiny habit that makes a huge difference. If you ever feel stuck or the hood still under‑performs after a clean, give Bridgewater Appliance Fixers a shout. Our techs can check the fan motor, ductwork, or any hidden issues fast and affordable.
