The MERV 11 rating does a fantastic job of capturing allergens and pet dander, making a noticeable difference in the air quality of my home. I appreciate how well they fit into my HVAC system, ensuring reliable airflow every time I use it.These filters are designed to last three months, which is convenient, and I love that I received a pack of four. This not only offers great value, but I can easily swap them out without worrying about running out any time soon.Overall, I highly recommend these air filters to anyone looking to improve their indoor air quality while ensuring their HVAC system functions efficiently. They deliver on their promises and have made my home feel much fresher. Five stars! ### ⭐⭐⭐⭐⭐ Great Furnace Filters *by on Reviewed in the United States July 21, 2026* I have never purchased these furnace filters through Amazon. Four filters individually wrapped in a resealable box, great for storing. I only use these filters, they keep dust to a minimum, the size 16x25x1, works perfectly, easy to install, and I highly recommend them. The price point was better than expected. ### ⭐⭐⭐⭐⭐ Great Balance Between Air Flow and Filter Quality - At A Good Price! *by on Reviewed in the United States June 8, 2026* This air filter is nice! At a MERV 11 rating, it has a great balance between allowing a sufficient air flow and filtering out particles. The size was accurate and fit in my 18x18x1 air intake slot. It arrived in great condition, and the material that the frame is made of is quite sturdy, which is nice. The 4-pack is a great option as well because it aligns perfectly with the 3-month recommended replacement schedule for air filters, so you're set for a full year once you buy a pack. ## Frequently Bought Together - Filtrete 20x20x1 AC Furnace Air Filter, MERV 11, MPR 1000, Micro Allergen Defense, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 4 Pack (Actual Size 19.69x19.69x0.81 in) - Filtrete 14x14x1 AC Furnace Air Filter, MERV 11, MPR 1000, Micro Allergen Defense, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 2 Pack (Actual Size 13.81 x 13.81 x 0.81 in) --- ## 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.tn/products/2329128-filtrete-20x20x1-air-filter-merv-11-mpr-1000-allergens-pet](https://www.desertcart.tn/products/2329128-filtrete-20x20x1-air-filter-merv-11-mpr-1000-allergens-pet) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-22*
