We manufacture compatible replacement whole house air filters that will maintain your Armstrong system and clean your air from particulates, dust, and allergens. The correct air cleaner for these Armstrong Air units is a 20x25x5.  Model numbers include AE20A-1, AMC20A-1, and ABS20-1.  Apply foam gaskets lengthwise to help prevent airflow bypass.
