Carrier 58STA135 Air Filter
It is recommended that the air filter gets replaced four times a year for optimal air quality in the home. All air filters are made in lots of styles and sizings, which depends on your particular desire for cleaner air and whether anyone suffers from allergies in the home. The height, length and width of the air filter can not be a choice of options but rather a requirement of your HVAC blower system.
What are the signs that the air filter really needs to be replaced?
- Sunlight will not infiltrate to the opposite side of the dirt filled filter
- The main filter looks like it is filled with dust and probably should be replaced right away
- Professionals have advised to swap out your air filter every 90 days to keep the air inside clean and free of harmful dust
