GE AZ22E12D3CM3 Filter
The unit filter has the basic duty of filtering out dust and other unwanted bits as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it operate more efficient while, at the same time, filtering the air in your home. Due to the amount of dust in the house, the air filter must be replaced or cleaned periodically in order to keep things clean.
Major signs of a weak main filter
- The main filter looks like it is filled with dust and replacing it would be best immediately
- Many pros have advised to replace the filter every season of the year to keep the air fresh for the family
- With a light behind the air filter, the light will hardly shine through to the other side of a dirt-packed filter
