Friedrich US14C30 Filter
The unit filter is designed to be good at filtering out dust and other tiny particles from the inside air inside the home. This simple filter can make the unit cleaner and make it work way more efficiently while cleaning the dust out of the air you breathe all day. Because of the nature of filtering air, this filter should really be simply replaced or possible scrubbed clean every so often in order to keep things clean.
Warnings of a laboring main filter
- If you hold it up to the light, it will hardly shine through to the other side of a dirt-packed filter
- Manufacturers have recommended to replace your air filter every three months to help keep the air fresh and make the unit run more efficient
- The main filter looks very bad and it would be best to replace it now
