ABSTRACT:
A panel air filter assembly, for use in heating, ventilating and air conditioning (HVAC) systems, which has a single filter element with multiple portions. The single filter element is sectioned into substantially equally-dimensioned and separate filter portions. Each of the filter portions includes a specific type of medium and is distinct from one another, so as to remove different types of contaminants from the outdoor supply air before entering heating, ventilating and air conditioning systems. A waterproof paperboard frame securely supports the filter element at the filter element's marginal edges.
