Williams 4007332 Filter
The filter in the wall unit is there for removing small dust molecules and other particles as it passes through. This simple filter can make the unit cleaner and make it work way more efficiently while also cleaning the air breathe in and out everyday. During regular maintenance the unit filter must be simply replaced or perhaps cleaned thoroughly a few times a year depending on how much you use it.
Some warnings your filter is not going to last much longer
- Many pros have suggested to replace the filter about every three months to help prevent mold and bacteria build-up
- Sunlight will hardly show through the filter
- The filter looks dusty and replacing it would be best before tomorrow
