ABSTRACT:
An air filter assembly and more specifically the use and combination of a relatively inexpensive and easily replaced paper filter associated with a conventional polyfoam or fiberglass filter conventionally employed in an intake of an air duct system associated with an air conditioning system or air heating system utilized in homes, offices and the like. Specifically, the air filter assembly includes a rolled filter paper that is drawn across the upstream side of a polyfoam filter or fiberglass filter which acts as a support for the filter paper with the paper filter being replaced periodically by moving a new segment of paper filter from the paper supply roll to a position in alignment with and in engagement with the polyfoam filter and disposing of the used paper filter. An inspection window is provided in the air intake louver door normally provided in air conditioning/heating systems to enable the condition of the paper filter to be observed to determine if the paper filter should be changed. In one embodiment, the paper filter is manually pulled to move a new segment into alignment with the polyfoam filter. In another form, the paper filter is moved from a supply roller into a take-up roller in the canister by a drive assembly which provides automatic movement of the paper filter at predetermined intervals.
