Carrier 52M Filter
The filter in the wall unit has a main job of trapping really small dust parts and other small elements from the inside air inside the home. This filtering system will help keep the unit clean and make it work way more efficiently while cleaning the air in your home. Due to the amount of dust in the house, the filter should probably be simply replaced or perhaps cleaned thoroughly periodically in order to keep things clean.
What happens when my main filter really needs to be replaced?
- Light does not shine through to the other side of the air filter
- The system filter looks gray or brown and it would be best to replace it without delay
- Manufacturers have advised to replace your air filter four times a year to keep the air inside clean and free of harmful dust
