How to Clean a Hood Filter
Hood filters decreases the amount of smoke and heat from your kitchen. (kitchen image by AGITA LEIMANE from

Hood filters are used in many commercial restaurants. Hood filters gather heat from ovens, grills and fryers to keep kitchen temperatures from getting to hot. Hood filters also collect and filter smoke to prevent it from leaving the kitchen and entering the dining room. Hood filters gather grease, smoke and oil residue from cooking. Degreaser is the best product to remove build-up on your hood filters.

  1. 1

    Remove the hood filters from the range hood slots. Use your hand or a hood remover to lift up the bottom of the hood filter. Pull the bottom of the hood filter toward you and remove the hood filter from the range hood. Repeat this step to remove the remaining hood filters.

  2. 2

    Stand the hood filters up against an outside wall near a drain.

  3. 3

    Pour some degreaser into an empty spray bottle. Spray the hood filters with degreaser. Hood filters have ribs to filter through the air, and grease may get stuck behind the ribs. Spray behind the ribs to make sure you remove all of the grease build-up.

  4. 4

    Soak the hood filters in the degreaser for several minutes. Use a hose to rinse the degreaser off of the hood filters. Spray behind the ribs to remove the grease from inside the filter.

  5. 5

    Use a towel to dry the water off of the hood filter. Wipe clean any leftover grease or build-up. If your hood filters have not been cleaned in a while, use a scrubbing pad to remove any tough build-up.

  6. 6

    Return the hood filter to the range hood. Lift the hood filter with your hand and guide the top into the range hood slot. Once the top of the hood filter is in the range hood slot, guide the bottom of the hood filter into the bottom range hood slot sliding it back into position.
