Air Filter WP85X10008

The air filter keeps dirt, dust, and other airborne particles from getting into your home. Blocked or restricted air filters are the most common cause for window air conditioners to not blow air. If the air filter becomes dirty or clogged, there will be little or no air flow over the evaporator coils. This causes frost to form due to constant cold air and no circulation, resulting in little or no air being circulated into the room. The air filter is positioned in front of the evaporator which is located behind the front grille. Regular replacement or cleaning of the air filter is essential to maintaining the efficiency of the air conditioner.
