14x30x1 air filter: actual size, MERV, and price
A 14x30x1 is a less common one-inch-class rectangle furnace or AC filter. Buy the printed size 14x30x1. The panel is smaller than 14 by 30 inches — Filtrete titles commonly print 13.81 × 29.81 × 0.78 or 13.81 × 29.81 × 0.81, with MPR 1000 closer to 13.68 × 29.68 × 0.81, and Nordic Pure about 13.94 × 29.94 × 0.75 (1315⁄16 × 2915⁄16 × ¾).
Same panel, swapped axes: 30x14x1. We treat 14x30x1 as the canonical label. Order 14x30x1.
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: 1-inch racks take ~¾ inch media. Honeywell Store does not list a 14x30x1. Amazon Basics search did not return a 14x30x1 SKU. Those brands are omitted rather than guessed.

If you currently run Filtrete MPR 1000 (13.68 × 29.68) and switch to Nordic Pure (~13.94 × 29.94), expect a snugger slide-in. Filtrete 13.81 vs 13.68 can matter in a tight slot. Filtrete’s published actuals also disagree with each other by SKU. Measure the old filter if the slot is tight. Full method: how to measure.
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 14x30x1 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 |

Pack prices checked 30 Aug 2026
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 14x30x1: about $9.75–$13.20/filter at MERV 8 in Nordic Pure packs, $13.79 at MERV 12 in a Filtrete 6-pack, $12.75–$23.00 at MERV 13, with a Filtrete 2-pack costing more per filter than Nordic Pure multi-packs. This size is less common than 14x25x1 or 16x25x1. Honeywell Store returned 404 for 14x30x1 MERV 8/11/13 pack product URLs, so those rows are omitted. Amazon Basics search did not return a 14x30x1 SKU. Target listed Filtrete 14x30x1 MPR 1000 1-pack (A-14393846) and 2-pack (A-51885585) but the product pages loaded without a public cart price, so those packs are omitted rather than guessed. Amazon Filtrete MPR 1000 2-pack returned a bot check; MPR 700 6-pack (B0F9LX1VNY) was out of stock with no featured cart price; MPR 1900 6-pack (B07FNQTB1X) printed $69.98 against a $34.99/count figure that does not match a 6-count, so that pack price is omitted. Nordic Pure 12-packs were not listed on JB Tools for this size.
