Match & price

Full answer

A 16x20x2 is a two-inch-class rectangle furnace or AC filter — not a 1-inch return slot and not a 4-inch cabinet cartridge. Buy the printed size 16x20x2. Do not substitute a 16x20x1. Do not mix with a 16x20x4. The panel is smaller than 16 by 20 by 2 inches: published actuals cluster around 15.5 × 19.5 × 1.75 (1¾ inch actual thickness, typically).

Full answer

Same panel, swapped axes: 20x16x2. We treat 16x20x2 as the canonical label. Order 16x20x2.

Actual dimensions by brand

Actual size by brand

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. A 16x20x1 (~¾ inch) will not fill that slot. A 16x20x4 (~3⅝–4⅜ inch) will not go in it.

Nordic Pure 16x20x2 pleated 16x20x2 Approximately 15.5 × 19.5 × 1.75 (15½ × 19½ × 1¾) JB Tools listings for 16x20x2M8-3, 16x20x2M8-12, 16x20x2M12-3, 16x20x2M13-3, and 16x20x2M13-12

Honeywell Store does not list a 16x20x2 pack (their 16x20 line on that store is 1-inch and 4-inch). Amazon Basics has no 16x20x2 SKU with a printed actual. Filtrete’s Amazon listing prints 15.5 × 19.5 × 1.75 as exact dimensions and 15.81 × 19.81 × 1.81 in the spec table — 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 16x20x2 use
8 ≥20% of 1.0–3.0 µm; ≥70% of 3.0–10.0 µm Common pleated replacement in a 2-inch rack 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. Not HEPA

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 16x20x2M12-3 is labeled MERV 12 — between the EPA 11 and 13 rows above; we do not invent a MERV 12 EPA line.

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 16x20x2 SKU. A 16x20x1 or a 16x20x4 is not a substitute by name alone.
