A changeable air filter is good at filtering out dust and other tiny particles as it is being forced through the system. This helps help keep the wall unit from building up too much dust and make it operate a lot better at doing its job while cleaning the air breathe in and out everyday. During regular maintenance the filter should be changed out or perhaps washed periodically in order to keep things clean.
Subtle hints your filter needs replacing
- The unit air filter looks dirty and probably should be replaced immediately
- If you place a light source behind it, the light is unable to shine on the opposite side of a dirty filter
- Professionals have suggested to swap out your air filter about every three months for clean air inside the house
