Haier ESA424J-L Filter
The filter in the wall unit was designed for filtering out dust and other tiny particles as it is being forced through the system. The filter can both keep the unit dust-free and make it work more efficient while also filtering the air in your home. Due to the fact that this is an important part of the system, the air filter must be swapped out for a new one or possible scrubbed clean every so often depending on how much you use it.
Major signs your filter needs replacing
- Many pros have recommended to swap out your air filter every season of the year in order to have clean air in the home
- The filter looks dirty and it would be best to replace it today
- If you place a light source behind it, the light cannot infiltrate to the opposite side of a dirty filter
