Frigidaire LRA12HZT20 Filter
The filter in the wall unit is the best line of defense when removing small dust molecules and other tiny bits as it passes through. This helps protect the unit and make it run a lot better at doing its job while, at the same time, filtering the dust out of the air you breathe all day. Because of this, this filter should really be simply replaced or perhaps washed periodically in order to keep things clean.
Major signs of a barely functioning filter
- If you were to lift up the filter, the light will not shine through to the other side of the dirt filled filter
- Many pros have recommended to switch out the air filter in your unit four times a year in order to have cleaner breathable air inside
- The air filter looks gross and could be replaced before tomorrow
