Full answer

A 20x25x2 is a two-inch-class rectangle furnace or AC filter — typically about 1.75 inches thick in the slot. Do not substitute a 20x25x1. Do not mix it up with a 20x25x4. Buy the printed size 20x25x2. The panel is smaller than 20 by 25 by 2 inches. Filtrete, Nordic Pure, and Filterbuy commonly print 19.5 × 24.5 × 1.75.

Full answer

Same panel, swapped axes: 25x20x2. We treat 20x25x2 as the canonical label. Order 20x25x2.

These numbers are copied from manufacturer or merchant product copy, not from a competitor size chart. Thickness is part of the fit: 2-inch racks take ~1¾ inch media, not a ¾ inch 1-inch panel and not a 4-inch cabinet cartridge.

Nordic Pure 20x25x2 pleated (MERV 8, 12, and 13) 20x25x2 Approximately 19.5 × 24.5 × 1.75 (19½ × 24½ × 1¾) JB Tools listings for 20x25x2M8-3, 20x25x2M8-12, 20x25x2M12-3, 20x25x2M12-12, 20x25x2M13-3, and 20x25x2M13-12. Amazon Nordic Pure MERV 12 3-pack title prints the same 19½ × 24½ × 1¾

If you currently run the common 19.5 × 24.5 × 1.75 cut (Filtrete, Nordic Pure, Filterbuy) and switch to BestAir’s 19.75 × 24.75 × 1.75, expect a snugger slide-in. A 20x25x1 (~¾ inch thick) will not fill a 2-inch rack. A 20x25x4 is a different cabinet. 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 2-inch MERV 13 is not HEPA. We do not claim health outcomes.

MERV EPA average capture efficiency (particle size) Typical 20x25x2 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 2-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 2-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. Compare MERV to MERV. Nordic Pure also sells a MERV 12 20x25x2; that SKU is in the price table, not in this EPA 8/11/13 grid.

Where these prices came from

Pack prices checked 30 Aug 2026

Amazon rows re-checked 27 Sep 2026 against the live featured-offer buy-box in a headed browser (Buy links now open the exact listing named in each row). Other merchants keep their own stamps.

These are public shelf/cart prices we recorded on 30 Aug 2026. They are not live. Shipping, subscribe-and-save, and store-only deals will move them. Per-filter math is pack price ÷ count, rounded to the cent.

Observed range that day for ordinary pleated 20x25x2: about $9.37–$14.10/filter at MERV 8 in multi-packs, $14.77–$19.99 at MERV 11, $10.12–$14.55 at MERV 12 (Nordic Pure), $13.50–$19.99 at MERV 13, with smaller packs costing more per filter than 12-packs. Honeywell Store had no 20x25x2 SKU (1-inch 20x25x1 pages only). Amazon Basics had no 20x25x2 listing with a printed actual, so that brand is omitted. Walmart Filtrete pages were not used for prices. Filterbuy.com size-chart pages were not used for dimensions; Amazon Filterbuy product listings print 19.50 × 24.50 × 1.75 on the SKU itself. Nordic Pure Buy buttons go through Awin to nordicpure.com. Factory cart pack prices for listed MERV 8, MERV 12, and MERV 13 12-packs and 3-packs were verified 15 Sep 2026 from nordicpure.com.

Where to buy (all stores)

Where to buy

No ranking. Stock and price change. If the slot is an odd fraction that none of these actual sizes match, measure first — that is not a 20x25x2 SKU. A 20x25x1 or 20x25x4 is not a substitute unless the published actual depth matches the old filter.
