  1. Open the Filter Cover

    Many filter covers have latches that can be opened to access the filter; however, some are attached with screws that you need to remove with a screwdriver. Be sure to put the screws in a safe place. If you are working on an overhead HVAC vent, use a sturdy stepladder.

  2. Rinse Away the Dust

    Now that the bulk of the dust has been removed, move to a sink and hold the filter under warm water or use the spray attachment to remove smaller dust particles. Start at one side and work your way down the filter so that the dirty water runs off of it and doesn’t redeposit on the filter.

  3. Dry the Filter

    It is very important to completely dry the filter with a soft towel before reinserting it into any appliance. If possible, place the filter outside or in front of a fan to make sure it is completely dry before reinserting. While you are waiting for the filter to dry, clean the appliance or vent opening where you removed the air filter to get rid of any dust or cobwebs.

    How to Clean an HVAC Air Filter

    For best results, plan to clean your home’s air filters about once a month and replace them about every six months. Be sure to check the manufacturer’s instructions to determine the best way to clean your air conditioner or furnace filter, but the steps below will work for most reusable filters.

    step 1: Turn off the power and locate the filter.

    Before you begin, turn off your HVAC unit to prevent unfiltered air from circulating around your home while cleaning. Locate the vent and use a screwdriver to open the unit. Some systems might include multiple vents that each contain a filter, so be sure to clean them all. Remove the filter and inspect it for damage. Replace the filter if necessary; otherwise, continue on to vacuuming.

    Step 2: Vacuum the air filter.

    Take the filter outside if possible to avoid stirring up dust inside your home. Use a vacuum with a soft brush attachment to remove debris from the filter. Run the brush across the filter to gently loosen stuck-on buildup.
