The cooking range filter (often part of a range hood or built-in extractor) traps grease, oil vapor, and food particles. Regular cleaning keeps airflow strong, reduces odors, and lowers fire risk. Follow the steps below based on filter type for best results.

Before You Start (Safety)

• Turn off power to the range hood
• Let the filter cool completely
• Prepare gloves and a sink or basin
• Check the filter type before cleaning

Never clean a filter while it’s hot or while the hood is powered.

Step 1: Identify the Filter Type

Most cooking range filters fall into one of these categories:

• Aluminum mesh filter (washable, most common)
• Baffle filter (stainless steel, washable)
• Charcoal / carbon filter (not washable, replace only)

If you’re unsure, check the hood manual or look for material clues.

Step 2: Remove the Filter

• Press the release latch or slide the filter out
• Support it with one hand to avoid dropping
• Place it on a protected surface

Handle gently to avoid bending the frame.

Step 3: Clean Washable Metal Filters

Method A: Hot Soapy Water (Routine Cleaning)

1. Fill a sink with very hot water

2. Add dishwashing liquid

3. Submerge the filter fully

4. Soak for 15–30 minutes

5. Scrub gently with a soft brush

6. Rinse thoroughly

This method is suitable for light to moderate grease.

Method B: Baking Soda & Degreaser (Heavy Grease)

1. Place the filter in a large basin

2. Sprinkle baking soda generously

3. Add hot water to cover

4. Let soak 30–60 minutes

5. Scrub gently along the mesh or baffles

6. Rinse well

Avoid steel wool or abrasive pads.

Step 4: Dishwasher Cleaning (If Allowed)

Some metal filters are dishwasher-safe.

• Place filter vertically on the lower rack
• Use a normal cycle
• Avoid high-heat drying if possible
• Wash separately from dishes

Check the manufacturer’s guidance before using this method.

Step 5: Dry the Filter Completely

• Shake off excess water
• Air-dry fully or towel-dry
• Ensure no moisture remains in corners

Installing a wet filter can cause odors or corrosion.

Step 6: Reinstall the Filter

• Slide the filter back into position
• Make sure it locks securely
• Restore power

Run the hood briefly to confirm normal airflow.

Charcoal / Carbon Filters (Important Note)

Charcoal filters cannot be washed.

• Do not soak or rinse
• Replace every 3–6 months (or as specified)
• Reduced suction or lingering odors indicate replacement time

Washing charcoal filters destroys their odor-absorbing ability.

How Often to Clean the Filter

Recommended frequency:

• Light cooking → every 1–2 months
• Heavy or oily cooking → every 2–4 weeks
• Commercial-style use → weekly inspection

Regular cleaning prevents grease buildup and improves efficiency.

Common Mistakes to Avoid

• Using abrasive scrubbers
• Reinstalling while wet
• Ignoring charcoal filter replacement
• Cleaning with harsh chemicals
• Bending the filter frame

These issues reduce filter effectiveness and lifespan.

Summary

To clean a cooking range filter properly:

1. Turn off power and cool

2. Identify filter type

3. Remove carefully

4. Wash metal filters with hot water and mild cleaner

5. Dry completely

6. Reinstall securely

7. Replace charcoal filters when required

With routine care, a clean cooking range filter ensures better airflow, less odor, and safer kitchen operation.
