Can You Put Extractor Fan Filters in the Dishwasher

In our daily lives, the kitchen plays a central role as the heart of the home. It’s where we prepare meals, gather with family and friends, and experiment with new recipes. However, with all the cooking that takes place, it’s no surprise that kitchens can get messy. One essential tool for maintaining a clean and healthy kitchen environment is the extractor fan. It helps to remove smoke, grease, and odors, keeping the air in your kitchen fresh. But what about the extractor fan filters? Can you put them in the dishwasher to keep them clean and functional? Let’s dive into this topic and find out.

Understanding Extractor Fan Filters

Before we discuss whether or not you can clean extractor fan filters in the dishwasher, it’s important to understand what these filters are and why they are essential. Extractor fan filters are designed to capture grease, smoke, and other particles generated during cooking. They prevent these contaminants from recirculating into the kitchen air, which helps maintain air quality and reduces the risk of kitchen fires.

Extractor fan filters come in two primary types: metal and charcoal. Metal filters are made of aluminum or stainless steel mesh and are washable, while charcoal filters are disposable and need to be replaced regularly. To keep your kitchen’s air clean and your extractor fan functioning efficiently, it’s crucial to maintain these filters.

Cleaning Metal Extractor Fan Filters

Step 1: Remove the Filters

The first step in cleaning metal extractor fan filters is to remove them from the range hood. Most filters can be easily detached by releasing a latch or unscrewing a few bolts. Make sure to turn off the fan and allow the filters to cool if they’ve been in use.

Step 2: Pre-Wash

Before placing the filters in the dishwasher, it’s a good idea to pre-wash them. Use hot, soapy water and a brush or sponge to scrub away the initial layers of grease and grime. Rinse them thoroughly to remove any soap residue.

Step 3: Dishwasher Safe?

Now comes the crucial question: Can you put extractor fan filters in the dishwasher? The answer is yes, but with a few caveats. Ensure your filters are dishwasher safe. Check the manufacturer’s instructions or label on the filters to confirm.

Step 4: Dishwasher Cycle

If your filters are dishwasher safe, place them securely in the dishwasher’s top rack. Avoid overcrowding the dishwasher to allow for proper cleaning. Use a heavy-duty dishwasher detergent and run a hot-water cycle.

Step 5: Dry and Reinstall

Once the dishwasher cycle is complete, remove the filters and let them air dry completely. Ensure they are thoroughly dry before reinstalling them in the range hood.

Cleaning Charcoal Extractor Fan Filters

For charcoal extractor fan filters, the process is different as these filters are not designed to be washed and reused. Instead, they need to be replaced when they become saturated with contaminants or lose their effectiveness. Replacement intervals vary depending on usage and the manufacturer’s recommendations.


Maintaining a clean and functional extractor fan is essential for a healthy and pleasant kitchen environment. While metal extractor fan filters can be cleaned in the dishwasher, it’s crucial to check their dishwasher-safe status and follow the manufacturer’s guidelines. For charcoal filters, they should be replaced as needed to ensure optimal performance. By keeping your extractor fan filters clean, you’ll not only improve air quality but also extend the life of your appliance.


How often should I clean my metal extractor fan filters?

Cleaning frequency depends on usage, but a good rule of thumb is to clean them every 2-3 months or when you notice a significant buildup of grease.

Can I use regular dishwasher detergent to clean metal filters?

Yes, you can use regular dishwasher detergent, but it’s recommended to use a heavy-duty detergent for better grease removal.

What should I do if my charcoal extractor fan filter is emitting odors?

If your charcoal filter is no longer effective at removing odors, it’s time to replace it. Look for replacement filters designed for your specific extractor fan model.

Is it safe to run the dishwasher with extractor fan filters in it?

Yes, it’s safe to run the dishwasher with metal extractor fan filters as long as they are labeled as dishwasher safe. Be sure to follow the manufacturer’s guidelines.

Can I clean both metal and charcoal extractor fan filters in the dishwasher together?

It’s best to clean them separately. Metal filters can go in the dishwasher, while charcoal filters should be replaced when needed.
