Abstract
A filter support base for use with an upflow forced air furnace is disclosed. A rectangular base defining a return air plenum is adapted for floor mounting support of the furnace and includes a pass-through opening in communication with the intake opening of the furnace plenum. A filter base provides a rectangular enclosure that is secured intervening between the base and the supported furnace. Within the filter box there are elongated channel members extending about the internal perimeter in planar alignment with a filter access opening for support of a received filter element in the return air stream. A cover, hinge supported above the opening, is displaceable for covering the opening during normal furnace operation and for exposing the opening when filter access is desired.
