Cleaning an Air Filter

Air filters do exactly what they say, filter the air and need periodic cleaning. Two type of filters are common: washable and disposable. In this section, we clean the filter. This increases air flow, reduces load on the fan motor and prevents build-up on the ducts. If you are really concerned about air quality you might also explore the use of Indoor Air Purifiers.

Locate return duct

Step 1:

The first step is to locate the return duct. This is the one through which air returns to the heating and air conditioning unit. If you have a large house, there may be two of these.

Loosen cover screws

Step 2:

Using a screw driver, loosen the catch to open the cover. Be careful if this is a ceiling mount as the filter may drop right out.

Dirty, Dirty!

Step 3:

It's amazing how effective these filters are. Just look at the particulates that are trapped!

Spray with clean and rinse

Step 4:

Using a household cleaner, heavily spray the filter and rinse with hot water. The filter should be clean and allow a free flow of air.

Return the screen to the housing, close the cover and tighten the screw catches.
