Frigidaire CRA053PU11 Filter
The filter in the wall unit was created for filtering out dust and other miniscule particles from the air in the house. The filter can both keep the unit dust-free and make it run much more efficient while cleaning the air breathe in and out everyday. Because of the nature of filtering air, this filter should really be replaced or perhaps washed periodically in order to keep things clean.
Signs the primary air filter probably needs to be replaced
- The filter looks dusty and the best thing to do would be to replace it ASAP
- Many pros have suggested to swap out your air filter about every 90 days to help clean the indoor air
- When you hold it up, the light does not infiltrate to the opposite side of the filter
