What are baffle filters? 

Baffle filters are kitchen range hood filters that help remove grease and other contaminants from the air in your kitchen. 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 carrying 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 made of either 430 steel, aluminum, or mild steel. However, you will most often see them made of stainless steel. Stainless steel will last longer and filter grease better than filters made of aluminum.

How to clean baffel 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.

What you will need

  • Pair of waterproof gloves
  • Old tootthbrush or non abrasieve scrubber
  • Screwdriver
  • 1 cup of vinegar
  • 2 tablespoons of baking soda
  • 2 tablespoons of salt 

1. Turn off the range hood

Make sure 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 of filters and tilting the filters at an angle. In most cases, this will remove the filter. Make sure to have two hands on the filters to avoid them dropping onto your stovetop.

3. Seperste the top and bottom of the baffel 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 make your cleaning more effective. Also, take note of where you leave the screws. You will want them later for the reassembly process.

4. Fill yor 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. Make sure you fill it with enough water to fully 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, but you should not put the filter screws in the sink, you risk losing them down the drain.

6. Add your cleaning solution

There are many different types of cleaning solutions out there that can decrease your arranged filters. In this example, we’re using a homemade solution. Add the following to the hot water:

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

7. Brush or scrub along the groves

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

8. Leave it in the water for an hour

Use a dry towel to pat it down and removing any water that may be visible. You should also leave it out for about an hour or two just to make sure that it’s totally dry.

9. Reassemble the baffle filters

After the filter is fully dry, go ahead and 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 onto your arrangement

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

How to buy new baffle filters

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

Consult your range hoods user manual to make sure you get the right filters. If you don’t have a user manual for your range hood, try doing a Google search of 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 manufactures will have a sticker inside of the hood with the model number for just this reason. Hopefully, once you give a good look around your range hood, you will be able to identify its model number. When you finally have the number, do a quick Google search for the right filters and shop away.
