International Comfort Products NTG3075FBA3 Air Filter
Filters are available in many types and sizes, which depends on your particular choice for how clean you want the air and air handler requirements. It is highly recommended the your furnace filter is replaced for a clean one every 90 days or so due to the filter clogging up and restricting the flow of air in the home. The size of the filter is not a optional choice due to the requirement of whoever designed your heating and cooling system.
