Comfort Aire RAD-183B Filter
The filter in the wall unit is there for removing microscopic dust and other particles from the air in the house. This filtering system will help protect the unit and make it work much more efficient while, at the same time, filtering the dust out of the air you breathe all day. During regular maintenance the air filter must be changed out or possible scrubbed clean every so often in order to keep things clean.
Easy warnings of a bad main filter
- It looks bad and it would be a good idea to replace it as soon as you can
- Manufacturers have recommended to switch out the air filter in your unit every 90 days to keep the air fresh for the family
- Light will not shine through to the other side of a clogged air filter
