Dust Free Max-Aire Gold filter - 20x25x1

Today's high efficiency heat pumps and air conditioners require proper air flow. Without proper air flow, systems become inefficient, or in some cases may require major repairs. Consequently, electrostatic air filters must have arrestance to keep dust and other pollutants from accumulating on the coils and in the air. The MAX-Aire Gold electrostatic air filters has this special combination. It provides high arrestance at an industry leading 0.08" initial resistance.
