Keeping your kitchen extractor fan filter clean is crucial for maintaining a healthy and efficient cooking environment. One of the most effective and eco-friendly ways to clean your filter is by using vinegar, a natural deodorizer and disinfectant. Here's a step-by-step guide on how to clean your kitchen extractor fan filter with vinegar, ensuring a thorough clean while minimizing environmental impact.
Why Clean Your Extractor Fan Filter with Vinegar?
Vinegar is an excellent cleaning agent for several reasons:
- It's a natural deodorizer, helping to eliminate cooking odors and grease buildup.
- It's a mild acid, which makes it effective at cutting through grease and grime.
- It's non-toxic and safe to use around food, making it a healthier alternative to chemical cleaners.
- It's inexpensive and readily available, making it a cost-effective cleaning solution.
What You'll Need
Before you begin, gather the following materials:

- White vinegar
- Baking soda (optional)
- Spray bottle
- Large bowl or sink
- Scrub brush or sponge
- Rubber gloves
- Paper towels or clean cloths
How to Clean Your Extractor Fan Filter with Vinegar
Step 1: Remove the Filter
Begin by turning off and unplugging your extractor fan to ensure safety. Locate the filter, which is usually found at the bottom of the fan or in the recirculation mode housing. Remove it carefully, as it may be greasy.
Step 2: Pre-treat with Baking Soda (Optional)
For heavily soiled filters, consider pre-treating with baking soda. Sprinkle a generous amount onto both sides of the filter, let it sit for 15-30 minutes, then proceed to the next step.
Step 3: Soak in Vinegar
Fill a large bowl or your kitchen sink with enough hot water to submerge the filter. Add 1 cup of white vinegar to the water. Stir well to combine. Place the filter into the vinegar solution, ensuring it's fully submerged. Let it soak for at least 15-30 minutes, or up to several hours for heavily soiled filters.

Step 4: Scrub and Rinse
While the filter is soaking, prepare a spray bottle with equal parts white vinegar and water. After soaking, remove the filter and use the spray bottle to rinse off any remaining grease or grime. Using a scrub brush or sponge, gently scrub both sides of the filter to remove any stubborn residue. Rinse thoroughly with clean water.
Step 5: Dry and Reinstall
Allow the filter to air dry completely, which may take several hours to a full day. Once dry, reinstall the filter back into your extractor fan. Ensure it's secure and properly seated.
Preventative Maintenance
To keep your extractor fan filter clean and functioning efficiently, perform regular maintenance:
- Clean the filter every 1-3 months, depending on usage.
- Wipe down the fan blades and housing with a damp cloth and mild detergent monthly.
- Inspect the fan motor and ensure it's free of grease and dust.
By following this comprehensive guide, you'll have a clean, efficient, and odor-free kitchen extractor fan filter, all while using an eco-friendly and cost-effective cleaning solution.
