Frigidaire FAH125N2T2 Filter
The filter is there for removing microscopic dust and other small elements from the inside air inside the home. This can both help keep the wall unit from building up too much dust and make it operate a lot better at doing its job while also filtering the air breathe in and out everyday. Due to the amount of dust in the house, the unit filter must be replaced or simply cleaned periodically depending on how much you use it.
Key signs of a weak primary air filter
- Manufacturers have recommended to replace the filter every 90 days to help prevent mold and bacteria build-up
- The unit air filter looks gross and could be replaced right now
- When you hold it up, the light will barely permeate to the other side of the air filter
