How to Clean a Cooker Hood Filter: UK Guide

A cooker hood helps manage airborne grease and cooking odours, but the filter itself needs attention. Whether your extractor uses reusable metal mesh, disposable paper or an odour-control carbon filter, the right maintenance method depends on its design. This UK kitchen guide explains how to clean what is washable and replace what is not.

First: identify your cooker hood filter

Reusable metal grease filters

Aluminium mesh and stainless-steel filters collect airborne grease. Many can be removed and hand-washed. Some are dishwasher-safe, but check your cooker hood manual before using a dishwasher.

Disposable paper or non-woven filters

Paper and non-woven filter sheets are generally replaced when greasy or at the interval specified by the manufacturer. Do not assume they can be washed and reused.

Carbon or charcoal odour filters

These are commonly used in recirculating cooker hoods. Many are disposable, but some specialist long-life models can be regenerated or washed using model-specific instructions. Never wash a carbon filter unless its manufacturer explicitly permits it.

How to clean a metal cooker hood grease filter

Step 1: Switch off the appliance

Turn off the cooker hood and isolate it from the electrical supply before removing filters. Let nearby cooking surfaces cool.

Step 2: Remove the metal filter carefully

Support the filter while releasing the catch. Your hood's manual will show the correct removal method.

Step 3: Soak in warm, soapy water

Place the washable metal filter in a sink with warm water and mild washing-up liquid. A short soak can loosen accumulated grease. Follow the manufacturer's guidance on cleaning agents.

Step 4: Clean gently

Use a soft brush or non-abrasive sponge. Avoid steel wool and aggressive tools that could damage the mesh or finish.

Step 5: Rinse, dry and refit

Rinse away detergent and let the filter dry fully before refitting. Check that the catch is secure before using the hood again.

Can cooker hood filters go in the dishwasher?

Some reusable metal grease filters can, but not all. Consult the manual first: materials and finishes vary. Disposable paper filters and ordinary single-use charcoal filters should not go in the dishwasher.

How often should you clean or replace cooker hood filters?

There is no single interval suitable for every home. Regularly used metal grease filters often need checking and cleaning around monthly, or as indicated by the appliance. Disposable filter sheets should be replaced once saturated or according to their instructions. Charcoal filter replacement or regeneration schedules depend on the exact model and frequency of use.

When should you replace rather than clean a filter?

Consider replacement if a reusable metal filter is bent, torn, damaged or remains heavily clogged after suitable cleaning. Replace disposable paper or non-woven sheets rather than trying to scrub them clean. If airflow remains poor after maintenance, consult the appliance manual or a qualified technician.

Choosing replacement cooker hood filter paper

Jolafunbs currently lists Range Hood Filter Paper 46cm Non-Woven Oil-Proof 5/10M. Before buying, check the dimensions, fitting method and material requirements in your cooker hood manual. A sheet described as 46cm wide is not automatically suitable for every hood, and paper should never replace a required metal or carbon filter unless the manufacturer specifies it.

Common cooker hood cleaning mistakes

• Cleaning while the appliance is still connected to power.
• Washing disposable filter sheets or charcoal filters without manufacturer approval.
• Using harsh abrasive brushes on delicate metal mesh.
• Reinstalling filters while still wet.
• Buying a replacement without checking the hood's model and measurements.

Cooker hood filter FAQs

Can I clean a paper cooker hood filter?

Normally no. Replace disposable filter sheets when greasy or when instructed by the manufacturer.

Can I use my cooker hood without a grease filter?

Do not operate it without the required filter fitted. Follow the appliance manufacturer's safety instructions.

What if the extractor still smells after cleaning?

If your hood recirculates air, check whether the charcoal filter needs replacing or manufacturer-approved regeneration. Also inspect for other maintenance issues as directed in the manual.
