Frigidaire CRA226ST214 Filter
The filter in the wall unit is good at filtering tiny dust fragments and other tiny bits as it is being forced through the system. This can both make the unit cleaner and help it be way more efficiently while cleaning the air you breathe. Due to the fact that this is an important part of the system, it should be simply replaced or perhaps washed at least twice a year if not more, depending on how much you use it.
Simple indications of an inadequate filter
- It is highly advised to replace the filter about every 90 days in order to have clean air in the home
- Sunlight will almost not shine through to the other side of a very dirty air filter
- The filter looks gross and maybe should be replaced as soon as you can
