Frigidaire CRA073PT11 Filter
The filter in the wall unit has the basic duty of filtering out dust and other tiny particles from the inside air inside the home. This simple filter can make the unit cleaner and make it run much more efficient while also cleaning the air breathe in and out everyday. Because of the nature of filtering air, the filter should be swapped out for a new one or perhaps cleaned thoroughly a few times a year depending on how much you use it.
Indications the dust filter should be replaced
- The system air filter looks bad and the best thing to do would be to replace it soon
- Professionals have advised to replace the filter about every 90 days for clean air inside the house
- If you place a light source behind it, the light will not shine through to the other side of the filter
