The air filter is the best line of defense when removing small dust molecules and other unwanted bits from the inside air inside the home. This filtering system will help keep the unit clean and make it run more efficient while, at the same time, filtering the air you breathe. During regular maintenance the unit filter must be simply replaced or possible scrubbed clean periodically in order to keep things clean.
What are some indications that my air filter has a need to be replaced?
- The unit air filter looks gray or brown and probably should be replaced right away
- Light does not permeate to the other side of a dirt-packed filter
- Professionals have suggested to switch out the air filter in your unit every three months in order to keep the air free from too much dust
