The air filter has the main responsibility for filtering out dust and other particles from the inside air inside the home. This helps help keep the wall unit from building up too much dust and make it operate way more efficiently while also filtering the dust out of the air you breathe all day. Because of the nature of filtering air, the filter should be changed out or perhaps cleaned thoroughly every so often depending on how much you use it.
What are the indications that my dust filter is failing?
- The system air filter looks very bad and must be replaced before tomorrow
- It is suggested to switch out the air filter in your unit about every 90 days to help keep the air fresh and make the unit run more efficient
- When you hold the filter up to the light, it is unable to breach the other side of a very dirty air filter
