AprilAire air purifier (1410, 2410, 4400…)? Its MERV 13 cartridge is the AprilAire 413, not a generic 16x25x4 — see AprilAire 410 vs 413. Honeywell F100/F200 cabinet? See the FC200E1029 page.

Full answer

A 16x25x4 is a four-inch media filter for a dedicated cabinet. This page is only the MERV 13 slice of that size. Tonight (21 Oct 2026) we read six MERV 13 listings on Amazon and the Honeywell FC200E1029 2-pack on the Air Quality Honeywell Store. For a standard 4-inch rack (filters about 3-5/8 to 3-3/4 inches deep), the cheapest per filter on 28 Oct was the Filterbuy 4-pack at $89.96 ($22.49 each; it was $98.96 on 27 Oct), then the Aerostar 6-pack ($135.94, $22.66 each), the BNX TruFilter 2-pack ($53.86, $26.93 each) and the Nordic Pure 2-pack on Amazon ($62.69, $31.35 each). If your cabinet takes a deeper 4-3/8-inch cartridge (Honeywell F100/F200 style), look at the Honeywell FC200E1029 ($78.01 for one on Amazon; $165.00 for a 2-pack, $82.50 each, at the Honeywell Store) or the 4.31-inch Filtrete MPR 1900 2-pack ($72.07, $36.04 each).

Why MERV 13?

MERV 13 catches more fine particles (smoke, some bacteria, fine dust) than MERV 8 or 11, per the EPA MERV table. A 4-inch filter has much more pleat area than a 1-inch panel, so MERV 13 usually adds less airflow resistance in a media cabinet than it does in a thin slot. Change it on schedule (4-inch media typically lasts several months).

Actual size by brand
  • Aerostar 16x25x4 MERV 13: 15.5 × 24.5 × 3.75 (Amazon B01D94DBZY, “Actual size: 15 1/2"x24 1/2"x3 3/4"”).
  • BNX TruFilter 16x25x4 MERV 13: 15.5 × 24.5 × 3.63 (Amazon B0CCXKXXYF, “Actual Size: 15 1/2 x 24 1/2 x 3 5/8”).
  • Nordic Pure 16x25x4 MERV 13: 15.5 × 24.5 × 3.63 (Amazon B005ESNKRS, “Actual Size: 15 1/2 x 24 1/2 x 3 5/8”).
  • Filterbuy 16x25x4: about 15.5 × 24.5 × 3.63 (as recorded on our parent page).
  • Filtrete 16x25x4 MPR 1900: 15.88 × 24.56 × 4.31 (as recorded on our parent page).
  • Honeywell FC200E1029: about 15.94 × 24.87 × 4.38 (as recorded on our parent page; Amazon lists it as 16X25X4).

A 3-5/8-inch pack will leave a gap in a Honeywell 4-3/8-inch cabinet, and a 4-3/8-inch cartridge will not slide into a 3-5/8-inch rack. Measure the old filter first: how to measure.

FAQ

Is 16x25x4 the same as 25x16x4? Yes — same panel, axes swapped. It is not a 16x25x1 or a 16x25x5; buy the size printed on your current filter, and match the depth.

Which pack is cheapest per filter? On 28 Oct, the Filterbuy 16x25x4 MERV 13 4-pack ($22.49 per filter), just under the Aerostar Pro 6-pack ($22.66 per filter).

Will a Honeywell FC200E1029 fit my 16x25x4 slot? Only if the slot takes a 4-3/8-inch-deep cartridge (Honeywell F100/F200 style). Most generic 16x25x4 racks take 3-5/8 to 3-3/4 inches.
