Haier ESA3243 Filter
The filter is designed to be good at trapping really small dust parts and other tiny bits as it passes through. This simple filter can keep the unit clean and help it be much more efficient while also filtering the air breathe in and out everyday. Due to the fact that this is an important part of the system, the filter should probably be replaced or simply cleaned at least twice a year if not more, in order to keep things clean.
Clues to watch for to know your main filter is on its last leg
- Many pros have suggested to replace your air filter every 90 days to help prevent mold and bacteria build-up
- As you face it toward a light source, it will hardly show through the dirt filled filter
- The system air filter looks gross and must be replaced today
