International Comfort Products NTN6075FBG1 Air Filter
HVAC specialists suggest the your furnace filter is changed every 3 months so as to maintain good airflow in the home. Measurements of the air filter can not be a choice that needs to be made but rather a requirement of the manufacturer of your system. All air filters come in many filtering levels, which all depends on your personal demands for clean air and the specific size of filter you need for your system.
How do you know when your dust filter is not working right?
- The system air filter looks dirty and probably should be replaced right now
- It is advised to replace the filter every 90 days in order to have cleaner breathable air inside
- If you lift the air filter up to a source of bright light, the light will barely shine on the opposite side of the dirt filled filter
