Compatibility answer

Will the AprilAire 213 MERV 13 air filter work with the AprilAire 1210 Whole-House Air Purifier (media air cleaner)?

Yes. Both use AprilAire 20x25 media filter (210 / 213 / 216 family).

Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.

Why

  • ✓ Both use AprilAire 20x25 media filter (210 / 213 / 216 family).

Good to know

  • Nominal 20x25x4, but the actual size is about 20.6 x 26.63 x 4 in, so a generic 20x25x4 furnace filter is not a substitute.
  • Not interchangeable with the 16x25 410/413/416 family or the 20x20 310/313 family.
  • Older AprilAire 2120/2200 and Space-Gard 2200 cabinets need AprilAire Upgrade Kit 1213 before they take these filters.
  • MERV choices: 210 = MERV 11, 213 = MERV 13, 216 = MERV 16 (AprilAire recommends replacing the 216 every 6 months, the others every 12).
  • 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.
