Range hoods are responsible for cleaning the air in your kitchen. Keeping those filters nice and clean is essential to keep your range hood working properly, but how do you clean a baffle filter?

In this article, you will learn what baffle filters are, what they are made of, and how to clean them to ensure your hood is running its best.

What are baffle filters? 

Baffle filters are kitchen range hood filters that help remove grease and other contaminants from the air in your kitchen. In addition, they can be washed and reused when they become dirty, saving you the trouble and expense of purchasing and storing replacement filters.

How do baffle filters work?

As grease-saturated air rises through the filter, baffle filters force the air to change direction quickly and repeatedly. Because grease droplets cannot change directions as quickly as the air carries them, they condense on the metal blades and drain into the filter trays. A tray ensures that the grease does not accumulate and obstruct airflow or the filter’s overall function.

What are baffle filters made of?

Baffle filters are usually 430 steel, aluminum, or mild steel. However, you will most often see them made of stainless steel. This is because stainless steel will last longer and filter grease better than filters made of aluminum.

How to clean baffle filters?

Cleaning your range hood filters can be done with ease. Here is a list of the required materials you will need, along with the specific steps you should take to clean your baffle fitter.

  1. Turn off the range hood

    Ensure your range hood is turned off to avoid damaging the fan or any internal parts while removing the filters from the hood.

  2. Remove the filter from the hood

    Remove the range hood filters from the hood; this can easily be done by pressing into the latches of your back filters and tilting the filters at an angle. In most cases, this will remove the filter. But, again, ensure two hands on the filters to avoid them dropping onto your stovetop.

  3. Separate the top and bottom of the baffle filter

    Your filters should be able to be disassembled. You might have to find a screwdriver and unscrew them then. You can easily pull the two pieces apart. This will make cleaning the hood much easier and more effective. Also, take note of where you leave the screws. You will want them later for the reassembly process.

  4. Fill your sink with hot water

    This is probably a good time to put your waterproof gloves on. Clog up your kitchen sink and fill the sink with hot water. Please ensure you fill it with enough water to submerge the filter pieces.

  5. Submerge the filters

    Be sure to place both the top and bottom parts of the baffle filters in the sink. Make sure that they’re both fully submerged. It should go without saying that you should not put the filter screws in the sink; you risk losing them down the drain.

  6. Add your cleaning solution

    You can use many different types of cleaning solutions out there can degrease your filters. In this example, we’re using a homemade solution. Add the following to the hot water: one cup of vinegar, two tablespoons of baking soda, and two tablespoons of salt.

  7. Brush or scrub along the groves

    Use the toothbrush or non-abrasive scrub and swipe along each fin, removing all the access grease you see. Even if you don’t see grease anymore, keep scrubbing, as there may be a thin layer that is hard to see. Also, watch out for sharp edges! The filter fins may be very sharp.

  8. Could you leave it in the water for an hour?

    Use a dry towel to pat it down and remove any water that may be visible. You should also leave it out for about an hour to ensure it’s dry.

  9. Reassemble the baffle filters

    After the filter is fully dry, attach the top and bottom pieces. They should be the same process as when you just assembled the filter but in the reverse order.

  10. Attach them back to your arrangement

    Now all you have to do is reattach the filters to your hood, and that’s it! Presto. You’re done


  • 1 cup of vinegar
  • 2 tablespoons of baking soda
  • 2 tablespoons of salt


  • Pair of waterproof gloves
  • Old toothbrush or nonabrasive scrubber
  • Screwdriver

How to buy new baffle filters

If you need to purchase new baffle filters for whatever reason, you must ensure you get the right ones for your specific range hood.

Consult your range hood user manual to ensure you get the right filters. If you don’t have a user manual for your range hood, try doing a Google search for your model number and see if you can find a PDF digital version of the user manual.

If you don’t know the model number, it’s likely somewhere inside the hood. Most manufacturers will have a sticker inside the hood with the model number. Hopefully, once you look around your range hood, you will be able to identify its model number. Then, when you finally have the number, do a quick Google search for the right filters and shop away.

Are baffle filters better than mesh filters?

Easy to Clean: Because baffle filters do not easily become clogged with cooking grease, they do not require as frequent cleaning as mesh filters.

What best way to clean a vent hood filter with baking soda?

Before adding it to your water bowl, mix a squirt of liquid detergent with about a quarter cup of baking soda. Soak your filter by swishing it around with a brush. The baking soda should have loosened the grime after 10 minutes. With a soft brush, remove the remainder.
