Whirlpool 3PACH21DD0 Filter
The filter in the wall unit has the main responsibility for removing small dust molecules and other particles as it is being forced through the system. This helps keep the unit clean and make it operate much more efficient while also filtering the air breathe in and out everyday. Because of this, the filter should be simply replaced or cleaned periodically in order to keep things clean.
Indications of a faulty primary air filter
- Manufacturers have recommended to replace the filter about every three months in order to keep the air free from too much dust
- If you place a light source behind it, the light will barely breach the other side of the dirt filled filter
- It looks brown and perhaps should be replaced ASAP
