Frigidaire LRA18HMU212 Filter
The filter is designed to be good at removing microscopic dust and other tiny bits as it is being forced through the system. This simple filter can keep the unit clean and make it run more efficient while cleaning the air you breathe in your house. Due to the fact that this is an important part of the system, it should be swapped out for a new one or cleaned at least twice a year if not more, in order to keep things clean.
Clues of a poorly performing filter
- Manufacturers have advised to replace your air filter about every 90 days to keep the unit running efficiently
- The main filter looks very bad and must be replaced without delay
- Sunlight will not penetrate through a clogged air filter
