Broken Boiler: How Long Can You Manage Without One?
June 5 2025Kitchen Rangehood Filter: How to Clean, Replace & Keep It Working
Ever notice a lingering greasy smell after cooking, or your rangehood humming louder than usual? Most of the time it’s the filter that’s begging for attention. A clogged filter reduces airflow, makes your fan work harder, and can even cause a fire risk. Below you’ll find a simple, step‑by‑step plan to keep the filter in top shape without the hassle.
Why a Clean Filter Matters
The filter’s job is to trap oil, dust, and cooking fumes before they escape into your home. When it’s clean, the fan pulls air efficiently, your kitchen stays fresh, and your electricity bill stays low. A dirty filter does the opposite – air gets blocked, the motor overheats, and you might see grease build‑up on walls or cabinets. In short, a tidy filter protects your appliance, your home, and your wallet.
Quick Cleaning Routine (Under 15 Minutes)
1. Turn off the fan. Safety first – switch off the power at the unit or unplug it. Let the filter cool if it’s metal.
2. Remove the filter. Most rangehoods have a simple click‑or‑slide mechanism. Check your manual if you’re unsure.
3. Choose the right method. Aluminium mesh filters can be soaked in hot, soapy water, scrubbed gently, and rinsed. Charcoal or polymer filters need a vacuum or a soft brush; some are disposable and should be tossed.
4. Dry completely. Shake off excess water and let the filter air‑dry for at least 10 minutes. A damp filter will rust or rust‑spot.
5. Re‑install and test. Snap the filter back, switch the fan on, and listen. If it sounds smoother, you’ve done it right.
If you’re dealing with a heavy grease build‑up, add a splash of white vinegar to the wash water or use a dedicated degreaser. Avoid harsh abrasives – they can thin the mesh and reduce filtration.
When to Replace the Filter
Even the best‑maintained filter has a lifespan. Look for these signs:
- Visible tears or holes in the mesh.
- Persistent foul odour after cleaning.
- Reduced airflow despite a clean filter.
- Manufacturer recommendation – usually every 12‑18 months for metal, 6‑12 months for charcoal.
If any of these pop up, grab a matching replacement. Most retailers stock universal aluminium filters, but checking the model number ensures a perfect fit.
Tips to Keep Your Rangehood Happy
Set a calendar reminder to clean the filter every month if you cook daily, or every two months for light use. Keep a spare filter in the cupboard so you can swap it out quickly. Finally, schedule a professional check‑up once a year – a qualified gas engineer can inspect the fan motor, ductwork, and overall safety.
With a little routine care, your kitchen rangehood will stay quiet, efficient, and safe. No more greasy walls, no extra electricity bills, and no unexpected breakdowns. Give your filter the attention it deserves and enjoy a fresher kitchen every day.
