Carrier FV4BNF002000 Air Filter
Filters exist in many different types and sizes, which depends on your particular air quality needs and air handler size requirements. It is advised that the air filter is changed four times a year for optimal air quality through the ducts. Exact measurements of the air filter can not be a optional choice because of the constraint of your system.
How do you know when your Carrier air filter is not working right?
- The system air filter looks gross and it would be a good idea to replace it ASAP
- Professionals have suggested to switch out the air filter in your unit every three months in order for the machine to run more efficient and to breathe easier inside
- If you place a light source behind it, the light will barely show through a dirt-packed filter
