Frigidaire FRP77ETT3R0 Air Filter
Professionals in the industry advise that the air filter gets replaced four times a year due to the filter clogging up and restricting the flow of air through the ducts. Filters come in many filtering levels, depending on your desire for cleaner air and air handler size requirements. The measurement proportions of the filter is not really a choice that needs to be made because it is based on the declared size of your air handler.
