Williams 4007331 Filter
The unit filter has the main responsibility for filtering tiny dust fragments and other miniscule particles from the inside air inside the home. This simple filter can make the unit cleaner and make it operate much more efficient while also filtering the air you breathe in your house. Because it is really easy to do, this filter should really be exchanged or possible scrubbed clean a few times a year depending on how much you use it.
Indications of a worsening filter
- Manufacturers have recommended to switch out the air filter in your unit four times a year for clean air inside the house
- Sunlight does not show through a dirty filter
- It looks like it is filled with dust and must be replaced as soon as you can
