Comfort Aire RAD-81C Filter
A changeable air filter is responsible for filtering tiny dust fragments and other small elements as it passes through. The filter can both keep the unit clean and help it be much more efficient while cleaning the air you breathe in your house. Because it is really easy to do, the filter should be replaced or cleaned every so often depending on how much you use it.
Simple indications of a weak primary air filter
- The main filter looks gross and must be replaced before tomorrow
- With a light behind the air filter, the light does not show on the other side the dirt filled filter
- Manufacturers have advised to swap out your air filter about every 90 days in order to have clean air running through the unit
