Friedrich SL36 Filter
The filter is designed to be good at filtering minute dust particles and other tiny bits as it is being forced through the system. This simple filter can make the unit cleaner and make it operate much more efficient while also cleaning the air you breathe in your house. Due to the fact that this is an important part of the system, the unit filter must be replaced or simply cleaned periodically depending on how much you use it.
What happens when my dust filter really needs to be replaced?
- If you were to lift up the filter, the light will almost not break through to the other side of a very dirty air filter
- It is greatly suggested to replace the filter every 90 days in order to have clean air running through the unit
- The air filter looks dusty and should be replaced now
