Haier ESA3125 Filter
The air filter was designed for trapping really small dust parts and other small elements from the inside air inside the home. This simple filter can keep the unit clean and help it be more efficient while, at the same time, filtering the air in your home. During regular maintenance the filter should probably be swapped out for a new one or simply cleaned every so often depending on how much you use it.
Major indications of a weak filter
- It looks bad and it would be a good idea to replace it right away
- It is highly suggested to switch out the air filter in your unit four times a year to help keep the air fresh and make the unit run more efficient
- With a light behind the air filter, the light will hardly shine on the opposite side of a dirty filter
