Full answer
A 16x25x1 is a one-inch-class furnace or AC filter. Buy the printed size 16x25x1. The panel you hold is smaller than that label — usually about 15.75 × 24.75 × 0.75 inches, depending on the brand.
Full answer
Same filter, swapped axes: 25x16x1. Order 16x25x1.
MERV 13 SKUs only: 16x25x1 MERV 13.

If you currently run Nordic Pure (15.5 × 24.5) and switch to Filtrete (15.69 × 24.69 × ~0.81), expect a snugger slide-in. Measure the old filter if the slot is tight. Full method: how to measure.
MERV 8 vs 11 vs 13 (EPA facts)
MERV 8 vs 11 vs 13 (facts only)
MERV is ASHRAE 52.2, as summarized by EPA. Higher MERV captures a larger share of smaller particles. It also adds resistance. EPA says 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. A 1-inch MERV 13 is not HEPA. We do not claim health outcomes.
| MERV | EPA average capture efficiency (particle size) | Typical 16x25x1 use |
|---|---|---|
| 8 | ≥20% of 1.0–3.0 µm; ≥70% of 3.0–10.0 µm | Common pleated replacement when the manual does not call for higher |
| 11 | ≥20% of 0.30–1.0 µm; ≥65% of 1.0–3.0 µm; ≥85% of 3.0–10.0 µm | Mid-grade 1-inch pleat (Filtrete MPR 1000 is commonly labeled MERV 11) |
| 13 | ≥50% of 0.30–1.0 µm; ≥85% of 1.0–3.0 µm; ≥90% of 3.0–10.0 µm | Higher-efficiency 1-inch; confirm the furnace/air handler can take the extra pressure drop |
Source: U.S. EPA, “What is a MERV rating?”, last updated 14 Jan 2026. Filtrete also prints an MPR number; MPR is 3M’s scale, not MERV. FPR is a third scale. Compare MERV to MERV.
