I change out my filter almost monthly, it keeps the dust down and I burn a candle after dinner. They do the job. ### ⭐⭐⭐⭐⭐ JUST AS ADVERTIZED *by D***L on May 9, 2025* JUST AS ADVERTIZED ### ⭐⭐⭐⭐⭐ No Fancy Packaging, But Good Filters *by N***N on January 10, 2017* UPDATE: FYI! Watch your price on these... When I originally bought them in January 2017, they were $37.92 plus tax for a box of 6, but when I went to re-order them in August 2018, the price was jacked up to $50 and change before tax. Sooo... This year, I purchased "Aerostar Pleated Air Filter, MERV 13, 16x25x1, Pack of 6, Made in the USA" @ $37.99 instead, which--as you can see by the description--is an upgraded filter for the same price as I paid for these last year (MERV 13 vs. MERV 11).Before I purchased these, I did a lot of research as to what the different rating systems mean (MERV vs. MPR vs. DPR), who developed them, and how they compare to each other. Google it if you're curious. Very helpful. Armed with this knowledge, I purchased these filters and I'm happy with them. A few notes about the concerns of some of the other reviewers now that I've purchased these myself...1) "No markings on the filter--is this what I paid for?" - The MERV rating is very easy to miss, but it is there, so I've included a picture. (It's on the filter material, not on the frame.) Also, the brand and size can be found on the outside of the shipping box, which also doubles as a storage box for the filters, and features a label on the side where you can record the dates you've changed your filters. I've included pictures of all this, as well.My assumption about the lack of fancy packaging, color print, and copious labeling is that this is part of the reason these filters are offered at such an affordable price. I'll take it, especially since these are made in the USA. (Nobody sees the filter once it goes inside the unit, so I don't really care about the packaging. I just care that it does the job.)2) "I would've liked more folds." - The filters I received have a comparable number of folds to my old, name-brand filters. While I was looking at this, I noticed that the frame of these filters is actually sturdier than my name-brand filters on the non-airflow side, so I've also included pictures of both sides of each filter for comparison.3) "Annoying whistle." - I have not experienced this with the filters I received. I am happy with these filters, and will be purchasing again when needed. ## Frequently Bought Together - AIRx Filters Allergy MERV 11 AC Furnace Pleated Air Filter Replacement Box of 6, 18x20x1 Air Filter / 18x20x1 furnace filter Made in the USA - Simply 18x20x1 Air Filter, MERV 8, MPR 600, 6 Pack, For Home AC Furnace & HVAC (Actual Size: 17.75"x19.75"x0.75") DUST, Pet, & Allergy Control --- ## 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.vn/products/37415060-airx-filters-allergy-merv-11-ac-furnace-pleated-air-filter](https://www.desertcart.vn/products/37415060-airx-filters-allergy-merv-11-ac-furnace-pleated-air-filter) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
