Match & price

Honeywell F100/F200 media cabinet (16×20)? Its MERV 13 cartridge is the 4-3/8-inch FC200E1003 — see the FC200E1003 page (MERV 11 version: FC100A1003). All MERV levels: 16x20x4 size page.

Full answer

A 16x20x4 is a four-inch media filter for a dedicated cabinet. This page is only the MERV 13 slice of that size. On 23 Oct 2026 we read four MERV 13 listings on Amazon and the Honeywell FC200E1003 packs 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 27 Oct was the BNX TruFilter 2-pack ($46.49, $23.25 each), then the Aerostar 6-pack at $149.56 ($24.93 each; it was $150.95 on 26 Oct and $118.99 on 25 Oct), the Filterbuy 6-pack ($156.96, $26.16 each) and the Nordic Pure 2-pack on Amazon ($55.99, $28.00 each). If your cabinet takes a deeper 4-3/8-inch cartridge (Honeywell F100/F200 style), look at the Honeywell FC200E1003 ($360.00 for a 5-pack, $72.00 each, at the Honeywell Store). All MERV levels: the parent 16x20x4 size page.

Listings were found in one Amazon search pass (~9:13pm ET). The Filtrete MPR 1900 16x20x4 (standard depth) showed “Currently unavailable” and the Honeywell Home FC200E-1003 1-pack listing showed no featured price, so neither has a card. Air Quality Honeywell Store FC200E1003 5-pack $360.00, 4-pack $290.00 and 2-pack $165.00, product pages read 23 Oct 2026 (~9:00pm ET, in stock). Nordic Pure’s own site showed a bot check tonight, so its direct MERV 13 packs are on the parent 16x20x4 page (last read 22 Oct) instead of here.

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 16x20x4 MERV 13: 15.5 × 19.5 × 3.75 (Amazon B00R1UFK2K, listing states this actual size).
  • BNX TruFilter 16x20x4 MERV 13: 15.5 × 19.5 × 3.63 (Amazon B0D4WRFFD5, listing states this actual size).
  • Filterbuy 16x20x4 MERV 13: 15.5 × 19.5 × 3.63 (Amazon B00CK05LNY, listing states this actual size).
  • Nordic Pure 16x20x4 MERV 13: 15.5 × 19.5 × 3.63 (Amazon B005ESPBTI, listing states this actual size).
  • Honeywell FC200E1003: 15.875 × 19.875 × 4.375 (as on our FC200E1003 page).

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 16x20x4 the same as 20x16x4? Yes — same panel, axes swapped. It is not a 16x20x1 or a 16x20x5; buy the size printed on your current filter, and match the depth.

Which pack is cheapest per filter? On 27 Oct, the BNX TruFilter 16x20x4 MERV 13 2-pack ($23.25 per filter); the Aerostar 6-pack was $149.56 ($24.93 per filter).

Will a Honeywell FC200E1003 fit my 16x20x4 slot? Only if the slot takes a 4-3/8-inch-deep cartridge (Honeywell F100/F200 style). Most generic 16x20x4 racks take 3-5/8 to 3-3/4 inches.
