Frigidaire CRA226ST20 Filter
A changeable air filter is the best line of defense when trapping really small dust parts and other unwanted bits from the inside air inside the home. This simple filter can help keep the wall unit from building up too much dust and help it be much more efficient while also filtering the dust out of the air you breathe all day. Due to the amount of dust in the house, the filter should probably be swapped out for a new one or perhaps washed at least twice a year if not more, in order to keep things clean.
Clues to watch for to know the primary air filter should need replacing
- Professionals have suggested to switch out the air filter in your unit every 90 days to keep the house clean and less dusty
- The system filter looks gross and should be replaced soon
- As you face it toward a light source, it does not penetrate through a dirt-packed filter
