How to clean an electronic air filter

Electronic air filters are a nice convenience to have because they are reusable and more efficient. It is still important to make sure you are cleaning them every few months. Still, it’s super easy and this process only takes about an hour including the drying time.

If you have a normal furnace filter, here’s a guide to changing it.


Here are two ways to clean your electronic air filter:

First, turn off the electronic air filter by the switch on the top of it. Let it sit for 15-20 minutes to let any residual energy discharge from it. Be very careful with the filter to avoid cutting yourself or damaging the ionizing wires.

It is also important to check the owner’s manual on how to care for it.

1. Using your Tub:

  1. Fill your bath tub with hot water.

  2. Pour 1/2 cup of mild dish soap into the tub.

  3. Fully submerge the electronic air filter in the water.

  4. Let sit for 15-20 minutes.

  5. Remove from water and gently wipe grime off of the cells.

  6. Let it air dry for 45 minutes to an hour.

  7. Re-insert the electronic air filter back into your furnace.

2. Using a garden hose:

You can use a cleaner like Simple Green or mild dish soap.

Simple Green (or similar cleaner):

  1. Spray the cleaner on the filter.

  2. Let sit for 15 minutes to raise the dust/grime.

  3. Spray the filter with low pressure water (high pressure can damage the cells).

  4. Let it air dry for 45 minutes to an hour.

  5. Re-insert the electronic air filter back into your furnace.

Dish soap:

  1. It is important to use mild dish soap to avoid damaging the cells.

  2. Spray the filter with low pressure water.

  3. Apply the dish soap to the filter using a soft wet rag.

  4. Spray the filter again with low pressure water, rinsing all of the dish soap off of the filter.

  5. Let it air dry for 45 minutes to an hour.

  6. Re-insert the electronic air filter back into your furnace.
