A changeable air filter is there for removing small dust molecules and other unwanted bits as it passes through. This can both help keep the wall unit from building up too much dust and make it work much more efficient while, at the same time, filtering the air you breathe. Due to the amount of dust in the house, the air filter must be changed out or perhaps washed at least twice a year if not more, in order to keep things clean.
Indications of a bad air filter
- It looks brown and maybe should be replaced as soon as humanly possible
- Light will almost not infiltrate to the opposite side of the filter at all
- Many pros have recommended to replace your air filter about every 90 days to help clean the indoor air
