Aprilaire 201 vs 213 vs 413: Which Filter Fits Your 2200, 2210, 2400 or 2410?

Last checked 2026-10-24 9 sources

Quick answer

Go by your cabinet's model number. Aprilaire says the 213 fits 20 x 25 cabinets such as the 2210, the 413 fits 16 x 25 cabinets such as the 2410, the 2200 and 2250 take the 201, and the 2400 takes the 401. [S1] [S2] [S3] [S4]

  • The 213 and 413 are not interchangeable. Aprilaire lists the 213 at nominal 20 x 25 x 4 and the 413 at nominal 16 x 25 x 4. [S2] [S3]
  • Aprilaire says a 2200 can take the 213, and a 2400 the 413, once the upgrade kit (1213 or 1413) is installed. [S2] [S3]
  • Aprilaire says to change the 213 and 413 every 12 months, and the 201 and 401 every 12 to 24 months. [S1] [S2] [S3] [S4]

Aprilaire's 213 page lists the 2200 (Aprilaire and Space-Gard) with upgrade kit 1213 but doesn't list the 2250, so we only show the upgrade path for the 2200.

Aprilaire gives sizes as height × width × depth.

Find your model number first

The model number is on the cabinet, the boxed housing on the return duct beside your furnace. Once you have it, find it in the first table above. The filter you take out should carry the same number Aprilaire lists for that cabinet. [S1] [S2] [S3] [S4]

Don't go by "20x25x4" alone

The 210 and 213 are sold as 20 x 25 x 4, but Aprilaire lists their actual size as 20.6 × 26.63 × 4 inches. [S2] [S5] A standard pleated 20x25x4 is much smaller: Filterbuy's is 19.5 × 24.5 × 3.63. [S9] See 20x25x4 actual size by brand for the full comparison.

FAQ

Can I use a 213 in my Aprilaire 2200?

Only with Aprilaire's 1213 upgrade kit installed, according to Aprilaire. Without it, the 2200 takes the 201. [S1] [S2]

What filter does an Aprilaire 2400 take?

The 401. With Aprilaire's 1413 upgrade kit installed, Aprilaire says the 2400 can take the 413 or 410 instead. [S3] [S4] [S6]

Is a 213 the same as a 413?

No. Aprilaire lists the 213 at nominal 20 x 25 x 4 and the 413 at nominal 16 x 25 x 4, for different cabinets. [S2] [S3]

How often do I change an Aprilaire 213 or 413?

Aprilaire says every 12 months. [S2] [S3]

What we could not verify

  • The upgrade kit name. Aprilaire's 213 and 413 pages call it the 1213 and 1413 upgrade kit, and its 201 and 401 pages call it the U1213 and U1413 upgrade kit. We show the 1213 and 1413 names and haven't checked whether they are the same product.
  • Why Aprilaire's listed actual sizes are larger than the nominal size. Aprilaire's product pages don't say, so we haven't guessed.
  • Whether a non-Aprilaire filter fits these cabinets. We found no Aprilaire document that approves one.
  • The 216, 213CBN, 416 and 413CBN filters' sizes. We only list the filters whose pages we checked.
