Full answer

“16x20x5” is a media-cabinet cartridge, not a 1-inch slot filter. Most are Honeywell/Lennox replacements about 4⅜ inches deep: Air Quality Honeywell Store prints 15⅞ × 19⅞ × 4⅜ for FC200E1003, and Nordic Pure prints about 15.88 × 19.63 × 4.38 for its Honeywell/Lennox replacement. On 1 Nov 2026 the cheapest MERV 13 per filter was the Nordic Pure Honeywell/Lennox 4-pack at $39.56 each. Next: Nordic Pure Honeywell/Lennox 2-pack $82.99 ($41.50 each); Nordic Pure Honeywell/Lennox 1-pack $44.99 ($44.99 each); Honeywell FC200E1003 OEM 5-pack $360.00 ($72.00 each); Honeywell FC200E1003 OEM 4-pack $290.00 ($72.50 each); Honeywell FC200E1003 OEM 2-pack $165.00 ($82.50 each); Honeywell FC200E1003 OEM 1-pack $94.50 ($94.50 each). Match the depth of the cartridge you pull out.

Which cabinet do I have?
  • Honeywell F100 / F150 / F200 16×20 media air cleaner: the old cartridge is about 4⅜ inches deep (Honeywell FC100A1003 MERV 11 or FC200E1003 MERV 13). Any card on this page fits that cabinet.
  • Lennox Healthy Climate or other 16×20 media cabinet: check the old cartridge’s depth and face; if it is about 15⅞ × 19⅞ × 4⅜, a Honeywell/Lennox 16x20x5 replacement is the match.
  • Old filter about 3⅝ inches thick: that is a pleated 16x20x4, not this cartridge. Use the 16x20x4 page.

Measure the old cartridge depth before you order: how to measure.

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 4–5-inch media cartridge has far more pleat area than a 1-inch panel, so MERV 13 adds little airflow resistance in these cabinets (Honeywell publishes 0.28 in. w.c. at 500 FPM for FC200E1003), and the cartridge usually lasts 6–12 months. Check it when the season changes and replace it when it looks gray.

FAQ

Is 16x20x5 the same as 16x20x4? Sometimes. Honeywell labels its 4⅜-inch FC100A1003 / FC200E1003 cartridges 16x20x4, and most other stores sell that cartridge as 16x20x5. But a pleated 16x20x4 about 3⅝ inches deep is a different filter and will sit short in a 4⅜ cabinet. Match the depth of your old cartridge.

Which pack is cheapest per filter? On 1 Nov, the Nordic Pure Honeywell/Lennox 4-pack ($39.56 per filter).

Is the Honeywell FC200E1003 worth the extra cost? It is the genuine OEM MERV 13 cartridge; the Nordic Pure Honeywell/Lennox replacement is also MERV 13 and costs less per filter on 1 Nov. Both are about 4⅜ inches deep.

How often do I change a 5-inch MERV 13? Many 4–5-inch media cartridges are rated for about 6–12 months; sooner with pets, smoke or renovation dust. See how often to change.
