Full answer

A 16x16x1 is a one-inch-class square furnace or AC filter. Buy the printed size 16x16x1. The panel is smaller than 16 inches on each face — Filtrete closer to 15.81 × 15.81 × 0.81 or 15.81 × 15.81 × 0.78, and Nordic Pure about 15.75 × 15.75 × 0.75. Do not substitute 16x20x1 or 16x25x1 — those are different printed sizes.

We did not find a Honeywell Store 16x16x1 1-inch SKU (MERV 8/11/13 4-pack or 12-pack) that publishes actual dimensions, so that brand is omitted rather than guessed. We did not find an Amazon Basics 16x16x1 listing that publishes an actual-size field, so that brand is omitted rather than guessed. If you currently run Nordic Pure (~15.75 square) and switch to Filtrete (~15.81 square), expect a slightly snugger slide-in. Filtrete’s published actuals also disagree with each other by SKU (0.81 vs 0.78 thickness; one MPR 700 listing also prints 16 × 16 × 1). 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 16x16x1 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

Where these prices came from

Pack prices checked 30 Aug 2026

The Nordic Pure card prices above are one-time purchase prices re-read on nordicpure.com on 17 Oct 2026. Other figures in this section are public shelf/cart prices we recorded on 30 Aug 2026 unless a later date is given. 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 on 30 Aug 2026 for ordinary pleated 16x16x1: about $6.75–$6.97/filter at MERV 8 in Nordic Pure multi-packs, $8.25 at MERV 13 in a Nordic Pure 24-pack, with the 2-pack costing more per filter ($14.62). Honeywell Store product URLs for 16x16x1 MERV 8/11/13 4-packs and 12-packs returned 404, so those rows are omitted rather than guessed. Walmart Filtrete product pages were not used for this check. Amazon Filtrete pages were used for actual-size fields, not for this price table. Amazon Basics had no published 16x16x1 actual-size listing. Factory one-time purchase prices for the listed MERV 8 and MERV 13 2/4/24-packs were re-checked 12 Oct 2026 on nordicpure.com (every card matched; MERV and pack selected) (pick MERV and pack on the factory page). A 16x16x1 is not a 16x20x1 or a 16x25x1.

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 16x16x1 SKU. A 16x20x1 or 16x25x1 is not a substitute.
