Frigidaire FRA25ESU212 Filter
The air filter is the best line of defense when filtering minute dust particles and other unwanted bits as it passes through. This can both keep the unit clean and make it run more efficient while, at the same time, filtering the air you breathe. Because of the nature of filtering air, the unit filter must be swapped out for a new one or perhaps cleaned thoroughly periodically in order to keep things clean.
General warnings of a bad filter
- The main filter looks bad and should be replaced right now
- Many pros have advised to switch out the air filter in your unit every three months to help prevent mold and bacteria build-up
- With a light behind the air filter, the light will barely penetrate through a dirty filter
