Friedrich SL24 Filter
The unit filter has the basic duty of removing small dust molecules and other small elements as it passes through. The filter can both make the unit cleaner and make it work way more efficiently while, at the same time, filtering the air you breathe. Due to the fact that this is an important part of the system, it should be changed out or simply cleaned every so often depending on how much you use it.
Cues to watch for in a failing primary air filter
- The system filter looks dusty and it would be best to replace it today
- It is greatly suggested to swap out your air filter about every three months to assist in keeping the indoor air clean and fresh
- With a light behind the air filter, the light will hardly breach the other side of a very dirty air filter
