Good to know
  • Nominal 16x25x4, but the actual size is about 16.52 x 29.38 x 4 in; it is not a standard 16x25x4 furnace filter.
  • Not interchangeable with the 20x25 210/213/216 family.
  • Older AprilAire 2140/2400 and Space-Gard 2400 cabinets need AprilAire Upgrade Kit 1413.
  • AprilAire is moving these cabinets to 3-inch TriPure filters sold as kits with one-time upgrade rails (UK-series). Later TriPure refills (3F-series) need those rails installed; a classic 4-inch media filter does not use them.
