20x25x1 MERV 13: what to buy
Printed size is 20x25x1. This page is only the MERV 13 slice of that size — Honeywell Ultra, Filtrete packs that print MERV 13, and Nordic Pure MERV 13. Fit still depends on actual cut and thickness. Measure and compare brands on the parent 20x25x1 size page (full actual-size table and pack-price table).
Same filter, swapped axes: 25x20x1. Order 20x25x1.
What MERV 13 means here
MERV is ASHRAE 52.2, as summarized by EPA. MERV 13 is the band EPA cites as ≥50% capture of 0.30–1.0 µm, ≥85% of 1.0–3.0 µm, and ≥90% of 3.0–10.0 µm. A 1-inch MERV 13 is not HEPA. We do not claim health outcomes. Higher MERV adds resistance: a 1-inch MERV 13 typically drops more pressure than MERV 8 or 11 in the same slot. EPA’s upgrade language is to pick at least MERV 13, or as high a rating as your system fan and filter slot can accommodate, and to ask an HVAC technician if you are unsure.

3M prints MERV 13 on both MPR 1900 and MPR 2200 family pages. MPR is 3M’s scale, not MERV; compare MERV to MERV. Nordic Pure’s factory page does not show a price until MERV and pack are selected; the JB Tools figure is a reseller snapshot, not Nordic Pure’s factory cart. Target lists Filtrete 20x25x1 MPR 1900 MERV 13 as a 1-pack (A-14784657) and 2-pack (A-90627813); Buy links kept, but cart prices could not be re-verified 4 Sep 2026 (Target bot check / captcha), so those rows show Not verified instead of a stale dollar. No Target Filtrete MPR 1900/2200 6-pack or MPR 2200 20x25x1 SKU found. Walmart was not used for MPR 1900 because Target has those MERV 13 SKUs.

When not to buy MERV 13 in 1-inch
- The furnace or air-handler manual calls for a lower MERV (or a named brand/grade below 13). Follow the equipment, not a search query.
- An HVAC technician says the fan cannot take the extra pressure drop of a 1-inch MERV 13.
- The slot is a 4-inch (or 5-inch) media cabinet. A 1-inch MERV 13 is not a 4-inch media cartridge. See 20x25x4 if that is the printed size.
If you are unsure, ask an HVAC technician. EPA’s wording is at least MERV 13 or as high as the fan and slot can accommodate — not “always MERV 13 in every 1-inch rack.”
