Haier ESA408M Filter
The filter is the best line of defense when filtering tiny dust fragments and other tiny particles from the inside air inside the home. This filtering system will help keep the unit clean and make it operate way more efficiently while, at the same time, filtering the air breathe in and out everyday. Because of the nature of filtering air, it should be swapped out for a new one or perhaps cleaned thoroughly every so often depending on how much you use it.
Hints of a defective main filter
- The filter looks like it is filled with dust and maybe should be replaced immediately
- When you face it toward a light, the light does not show through a dirt-packed filter
- Manufacturers have suggested to replace the filter about every 90 days in order to have cleaner breathable air inside
