Why Cleaning Your Kitchen Hood Filter Is Important
Regular filter cleaning isn’t just about cleanliness—it directly affects safety and performance.
Improves airflow and suction
A grease-clogged filter restricts airflow, making your hood less effective at removing smoke and steam.
Prevents fire hazards from grease buildup
Grease is highly flammable. Letting it accumulate in your hood filter significantly increases fire risk.
Reduces odors and smoke
Old grease traps odors. Even after cooking ends, smells can linger if the filter isn’t clean.
Extends the life of the hood motor
When airflow is blocked, the motor works harder, leading to faster wear and costly repairs.
Types of Kitchen Hood Filters (Know Before You Clean)
Before you start, it’s important to identify your filter type. Cleaning methods vary.
1) Aluminum Mesh Filters
- Most common in home kitchens
- Lightweight and reusable
- Often dishwasher-safe (check manufacturer instructions)
These filters are ideal for soaking and scrubbing.
2) Stainless Steel Baffle Filters
- Found in premium or commercial-style hoods
- Heavy-duty and durable
- Best cleaned with soaking and gentle brushing
They handle grease well but still need regular cleaning.
3) Charcoal / Carbon Filters (Ductless Hoods)
- Used in recirculating (ductless) hoods
- Cannot be washed
- Must be replaced every 3–6 months, depending on use
If your hood uses carbon filters, cleaning won’t help—replacement is the only solution.

How to Clean Kitchen Hood Filter (Step-by-Step)
This is the most effective and beginner-friendly method for how to clean kitchen hood filter at home.
Step 1: Turn Off Power & Remove the Filter
Always switch off the hood and unplug it if possible. Carefully slide or unclip the filter according to your hood’s design.
Safety reminder: Filters can be sharp and greasy—wear gloves if needed.
Step 2: Soak Filter in Hot Water
Fill a sink or large basin with very hot (not boiling) water—around 60–70°C is ideal.
Add cleaning agents:
- 2–3 tablespoons baking soda
- A few drops of grease-cutting dish soap
Submerge the filter fully and soak for 15–30 minutes.
Step 3: Scrub Away Grease
Use a:
- Soft brush or non-scratch sponge
- Old toothbrush for corners
Avoid steel wool or hard brushes—they can damage the filter mesh or finish. Most grease should come off easily after soaking.
Step 4: Rinse and Dry Completely
Rinse thoroughly under warm running water until all residue is gone.
Why drying matters:
Moisture trapped in the filter can lead to odors, rust, or mold growth.
Air-dry vs towel-dry:
- Air-dry is safest and prevents lint buildup
- Towel-dry speeds things up but ensure no moisture remains
Reinstall only when the filter is completely dry.
FAQs – Kitchen Hood Filter Cleaning
Can I use vinegar to clean a hood filter?
Yes, vinegar helps cut grease, but it works best after baking soda soaking or for light grease. Avoid mixing vinegar and baking soda at the same time—they neutralize each other.
Does baking soda really remove grease?
Yes. Baking soda is alkaline, which breaks down acidic grease molecules, making them easier to remove.
Why does my hood still smell after cleaning?
Possible reasons include:
- Grease inside the hood fan or motor
- Charcoal filters that need replacement
- Ducting buildup
Filter cleaning alone may not fix deep internal odors.
How long does it take to clean a hood filter?
On average:
- Soaking: 15–30 minutes
- Scrubbing and rinsing: 10–15 minutes
Total time: about 30–45 minutes
