Full answer

Printed size is 12x12x1 — a small square 1-inch-class furnace, AC or return-grille filter. This page is only the MERV 13 slice of that size. Tonight (17 Oct 2026) we read Nordic Pure MERV 13 2-, 3-, 4-, 6-, 12- and 24-packs on nordicpure.com (via Awin), Honeywell Ultra Efficiency (MERV 13) 4- and 12-packs on the Honeywell Store, and Filtrete MPR 1900 (MERV 13) 2- and 6-packs on Amazon. The cut panel is smaller than the nominal size: Honeywell and Nordic Pure publish 11.75 × 11.75 × 0.75, and the Filtrete MPR 1900 (MERV 13) Amazon title prints 11.81 × 11.81 × 0.78. Lowest per filter: the Nordic Pure 24-pack, $169.99 ($7.08 each). This is not a 12x20x1 or 12x24x1. Compare all MERV levels on the parent 12x12x1 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
  • Nordic Pure 12x12x1 pleated: 11.75 × 11.75 × 0.75 (Nordic Pure factory page and JB Tools listing for 12x12x1M13-12).
  • Honeywell 12x12x1 Ultra Efficiency (MERV 13): 11.75 × 11.75 × 0.75 (Honeywell Store product specs).
  • Filtrete 12x12x1 MPR 1900 (MERV 13): 11.81 × 11.81 × 0.78 (Amazon B07FNW9VXG title “Act Size 11.81×11.81×0.78 in”).

If you switch brands in a tight slot, measure the old filter first: how to measure.

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 12x12x1 page and ask an HVAC tech. More on ratings: MERV explained.
