The Trane FLRQB5AH21M11 MERV 11 QuikBox Filter 20.7" x20" x4.70" is the correct replacement media filter for the Trane TFM and Trane QuikBox filter cabinets. This is a synthetic fiber filter in a chipboard frame that ships flat and pops up to a finished assembly in less than one minute. This filter will replace current Trane expandable type media and BAYFRAME kits that have been standard in the TFM filter cabinet. The QuikBox media is backward compatible to fit all TFM cabinets in the field, as well as new QuikBox cabinets. This Trane QuikBox Media Filter reduces household dust and allergens as an integral part of a whole home comfort system.

NOTE: Furnace filter cabinets are not included.
