What to do if Friedrich Air Cleaner air quality doesn't improve?
- SSherri WiseJul 26, 2025
If the air quality doesn't improve even after running your Friedrich Air Cleaner for a while, consider these possibilities: Ensure all filters are correctly installed in the proper order. Check if the pre-filter is dirty and needs cleaning. Verify that the air quality sensor is dry and clean. Also, the room size might exceed the unit's effective range.
