The unit filter was designed for removing microscopic dust and other miniscule particles from the air in the house. The filter can both protect the unit and help it be way more efficiently while, at the same time, filtering the air you breathe in your house. During regular maintenance the unit filter must be swapped out for a new one or cleaned at least twice a year if not more, depending on how much you use it.
Hints the air filter should need replacing
- Many pros have advised to replace the filter about every 90 days in order to have cleaner breathable air inside
- As you face it toward a light source, it will almost not breach the other side of the filter at all
- The unit air filter looks dirty and perhaps should be replaced right away
