It does a great job of capturing allergens like mold spores, pollutants from construction materials, lung damaging dust, pollen, dust mite allergens, most bacteria, Insecticide dust, smoke particles, auto emission particles, hair spray particles, plant spores, pet dander, carpet fibers, dog hair, cat hair, human hair, and more. A sample of these merv 13 filters when tested trapped 96% of large particles like pollen, 92% of particles like mold spores, and 46% of super fine allergens like cat dander in one pass. In addition to supreme filtration, the AirShield ultra-allergen filter has a longer service life than typical air filters lasting up to 90 days. High capacity in pleated air filters relates to the number of pleats in like filters. Simply stated, the more pleats in a filter, the better air flow and higher dust holding capacity; it works better and lasts longer than typical store bought pleated air filters. This air filter averages 18 pleats per ft vs. 12 - 16 pleats per ft in most store bought filters. Merv 13 air filters are used when seeking leed certification. After construction, before move-in, they are used along with outside air ventilation for about two weeks to flush the air of allergens generated from the build. Then, prior to occupancy, a new merv 13 air filter is installed. You may have noticed when selecting air filters at your favorite store that they are flimsy and can bow easily. Our filters are not like that. Every filter is manufactured with commercial quality. A bottom beverage board, tray-like frame is laid down, the wire-back pleated media is placed inside, then a the sturdy, moisture-resistant beverage board top frame is laid on top and glued to the bottom frame. The result is a sturdy, very effective air filter which is, by the way, made by hand in the USA. AirShield filters are manufactured by quality filters, inc. ## Features - Offers some of the highest residential filtration available - Traps 96% of large allergens; pollen, dust mites, pet dander, bacteria, mold spores, burning wood, cooking smoke, tobacco smoke, smog, etc - Lofted media fabric provides good airflow and ultimate allergen capture - Built strong like commercial filters to reduce air and dust bypass - Made in USA - ›See more product details ## Images ![AirShield 20001-202-0042 Ultra 20x30x1 MERV 13 Superfine Allergen Furnace Filters, 2 Pack, 20 x 30 x 1", 2 Piece - Image 1](https://m.media-amazon.com/images/I/51gdi0lEfyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must Buy *by B***C on Reviewed in the United States on May 6, 2017* Purchased 12 (12"x20"x1") at $6.55 each, local cost is 18.00 each. MERV 13 rate is accurate. I have been in the a/c field for 35+ years and these are Top Quality for the cost. They are made of heavy duty cardboard with exterior grade glue at all connections, no leakage around filter element and cardboard frame, expanded metal support structure to prevent element failure. I have them installed in my home in 2 return air filter housing grills (one per floor) for the past 2 weeks. The fitting size was snug for the existing frame. The only issue is they are not individually packaged, loose in box. Will purchase again. ### ⭐ The Filters Were Not Cut to the Right Size *by I***N on Reviewed in the United States on July 1, 2017* They did not cut these right regarding the size, so they were too big, and thus unusable. And by the time it was time for me to use them, it was past the return-period window.The listed size in the title 10 x 16 x 1 is the rounded-up size that these filter companies use. The actual cut size is supposed to be 9.5 x 15.5 x .8. If you read all the text on the page you'll see that these numbers are listed. But sadly, this company did not send the two filters I ordered in that correct size.I would never order from this company again. ### ⭐⭐ Long time to wait for a shady product *by S***S on Reviewed in the United States on July 3, 2017* The item was received irreparably damaged. I understand that accidents happen en route, but there are mailing precautions any seller takes for an item that can be easily crushed or bent (such as a stiffer box). Moreover, the item is advertised as a MERV 13 filter - a very good rating. However it seems this is actually a cheaper item with the MERV 13 sticker just added on. There are no other identifying marks other than air flow directions and size descriptions. The item I received was loose in the box and does not appear to be the one pictured. Maybe they are the same product, maybe they really are the listed rating, but what I received and how I received it doesn't make me terribly confident. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/51506824-airshield-20001-202-0042-ultra-20x30x1-merv-13-superfine-allergen](https://www.desertcart.jp/products/51506824-airshield-20001-202-0042-ultra-20x30x1-merv-13-superfine-allergen) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-09*
