Carrier 52SQ Filter
The unit filter is good at filtering out dust and other miniscule particles as it passes through. This can both help keep the wall unit from building up too much dust and make it work much more efficient while also cleaning the air you breathe in your house. Because it is really easy to do, the air filter must be replaced or possible scrubbed clean at least twice a year if not more, depending on how much you use it.
Indications your main filter needs to be replaced
- It is advised to replace the filter every 90 days in order for the machine to run more efficient and to breathe easier inside
- When you hold the filter up to the light, it is unable to infiltrate to the opposite side of a very dirty air filter
- The filter looks brown and it would be a good idea to replace it before tomorrow
