Amana-Goodman FIL36-42 Filter 19.5" X 21"

The Amana-Goodman FIL36-42 Filter is a replacement filter that can be used in furnaces, air conditioners, and heat pumps. This type of pleated filter provides gust coverage and realizes the function of filtering dust, ranking, pet dander, mold spores and other airborne particles to improve the indoor air quality and optimize the efficiency of your heating and air-conditioning systems. When the air goes through the filter, these elements get caught within the filter’s pleated layers so they cannot move around your house. It also improves the quality of living in your home, as well as, provides a shield to your HVAC.
