Frigidaire FRA123PT1 Filter
A changeable air filter is responsible for removing small dust molecules and other particles as it passes through. This can both help keep the wall unit from building up too much dust and help it be way more efficiently while, at the same time, filtering the air breathe in and out everyday. During regular maintenance the filter should probably be simply replaced or possible scrubbed clean a few times a year depending on how much you use it.
What symptoms are present when the filter is on its last leg?
- Manufacturers have advised to swap out your air filter every three months to help clean the indoor air
- With a light behind the air filter, the light will hardly shine through to the other side of a very dirty air filter
- The unit air filter looks bad and could be replaced right away
