International Comfort Products GPSM30K080F Air Filter
Filters come in a wide array of filtering types which all depends on your personal air quality needs and air handler size requirements. Measurements of the air filter can not be a personal choice because of the constraint of the manufacturer of your system. It is advised the your furnace filter is replaced for a clean one every 90 days or so to maintain the best air quality throughout the home.
Symptoms of a poorly working main filter
- It is greatly recommended to replace the filter about every three months in order to have cleaner breathable air inside
- When you hold it up, the light will barely show through the filter at all
- The unit air filter looks gross and it would be best to replace it right now
