Full answer

Printed size is 12x20x1 — a narrower 1-inch-class furnace or AC filter. This page is only the MERV 13 slice. Tonight (13 Oct 2026) we read Nordic Pure MERV 13 in 2-, 3-, 4-, 6-, 12- and 24-packs (nordicpure.com via Awin) and Honeywell Ultra Efficiency MERV 13 4- and 12-packs (honeywellconsumerstore.com). Actual sizes: Honeywell 11.75 × 19.75 × 0.75; Nordic Pure about 11.5 × 19.5 × 0.75 (JB Tools). This is not a 12x24x1 (four inches longer) or a 16x20x1. Compare all MERV levels on the parent 12x20x1 size page.

Why MERV 13?

MERV 13 catches more fine particles (smoke, some bacteria, fine dust) than MERV 8 or 11, per the EPA MERV table. In a 1-inch filter that comes with more airflow resistance, so it suits systems that run well with a denser filter. Change it on schedule.

Actual size by brand
  • Honeywell 12x20x1 Ultra Efficiency: 11.75 × 19.75 × 0.75 (Honeywell Store product specs).
  • Nordic Pure 12x20x1 pleated: about 11.5 × 19.5 × 0.75 (JB Tools listing for 12x20x1M13-12).
When not to buy MERV 13 in 1-inch

If your system manual limits filter resistance, or you notice weak airflow, a noisy blower or a frozen coil after switching, step down to MERV 8 or 11 on the 12x20x1 page and ask an HVAC tech.
