Goodman GSX130421 Air Filter
It is recommended that the air filter is swapped out every 3 months to maintain the best air quality in the home. The dimensions of the filter is not really a choice you make because of the constraint of your system. Filters are made in lots of styles and sizings, depending on your air quality needs and whether anyone suffers from allergies in the home.
How do you know when your primary air filter is about to stop working?
- Many pros have recommended to swap out your air filter four times a year so as to have cleaner breathable air
- If you lift the air filter up to a source of bright light, the light will barely show on the other side the air filter
- The system air filter looks dusty and perhaps should be replaced right away
