International Comfort Products H9MPX060F12A2 Air Filter
It is suggested that the filter is exchanged for a new one four times a year due to the filter clogging up and restricting the flow of air inside the house. The furnace filter can filter out contaminants and other particles from the air inside the house. The actual size of the filter is not really a choice you make because of the constraint of your HVAC blower system.
Important signs your main filter will eventually need to be replaced
- When you hold the filter up to the light, it will barely shine on the opposite side of a very dirty air filter
- The system air filter looks dusty and probably should be replaced as soon as humanly possible
- It is greatly recommended to replace your air filter about every 90 days in order to have clean air in the home
