Whirlpool CAW21D2A1 Filter
The filter has a main job of filtering tiny dust fragments and other tiny bits as it is being forced through the system. This filtering system will help protect the unit and make it operate much more efficient while, at the same time, filtering the air you breathe in your house. During regular maintenance the air filter must be replaced or cleaned every so often depending on how much you use it.
What are the indications that my main filter is in need of replacing?
- Filter looks filthy and clogged completely
- It is recommended to switch out the air filter in your unit every 90 days to keep the unit running efficiently
- When you face it toward a light, the light is unable to show through a completely clogged filter
