Haier ESA418J-L Filter
A changeable air filter is designed to be good at filtering minute dust particles and other miniscule particles as it is being forced through the system. This filtering system will help keep the wall unit from building up too much dust and make it run way more efficiently while, at the same time, filtering the air you breathe. Because it is really easy to do, the air filter must be swapped out for a new one or possible scrubbed clean a few times a year in order to keep things clean.
Red flags of a failing air filter
- Manufacturers have suggested to replace your air filter every 90 days so as to have cleaner breathable air
- As you face it toward a light source, it will almost not show on the other side the air filter
- The system air filter looks very bad and should be replaced without delay
