Air exchangers are devices used in homes and other structures to pull in fresh air and recover used air so it can be expelled from the building. Air exchangers not only help filter allergens from the air, but they also save energy. They use filters to capture dust, pollen and other pollutants in the air. Many types of filters are available, but the most common are filters that can be cleaned and reused several times.


Step 1

Disconnect the air exchanger from its electrical source. Remove the unit's front panel with a screwdriver. Lift the air filter carefully from its fitting.

Step 2

Vacuum both sides of the filter with the vacuum cleaner's hose attachment. Use the vacuum to remove dust and debris from inside the air exchanger unit.


Step 3

Rinse the filter with warm water until the water flowing through it runs clear. Dry the outside of the filter with a clean rag. Allow the filter to dry completely. Place it back inside the air exchanger.


Disconnect the air exchanger unit from the electrical power before opening the unit, to avoid electric shock.
