Not AprilAire — and not every “16x25x4”
- Honeywell FC100A1029 — 15⅞ × 24⅞ × 4⅜ for Honeywell F100/F200-class 16×25 cabinets.
- Honeywell FC100A1037 — ~19.88 × 24.88 × 4.38 for 20×25 cabinets. Hub: FC100A1037.
- Honeywell FC40R / FC313R return-grille media — 3″ top-hat for wall/ceiling grilles, not F100/F200 cabinet media. Hubs: FC40R, FC313R.
- AprilAire 210 / 213 / 216 — official actual 20.6 × 26.63 × 4. Different face. Compare: AprilAire 210 vs 213, AprilAire 216.
- Nordic Pure / Filterbuy “16x25x4” — often ~15.5 × 24.5 × 3.63. Shallower than 4⅜. Nordic Pure often points Honeywell 4⅜ owners at a 16x25x5 Honeywell-replacement SKU instead — measure before you order.
Some merchants also file the same ~4.38 Honeywell cartridge under a 16x25x5 label. Match the old cartridge’s printed model or tape-measure depth. Size hubs: 16x25x4 · 16x25x5.
Honeywell humidifier pads (HC-series water panels) are not FC100A1029 media cartridges. Pad guide: humidifier pads.

MERV 11 in context
MERV is ASHRAE 52.2, as summarized by EPA. FC100A1029 is labeled MERV 11. Higher MERV captures more of the smaller particle bands and adds resistance. A media MERV 11 is not HEPA. We do not claim health outcomes. Full 8 vs 11 vs 13 guide: MERV. Change interval by thickness: how often.
