Less expensive than the one furnace store offered. Highly recommend. ### ⭐⭐⭐⭐⭐ Good product, confusing information on listing *by G***E on November 15, 2021* I have been mostly using the Honeywell 20x20x5 filters for years and have been happy with them overall. All of these thick (4" and 5") are more expensive than they seem like they ought to be. Why is a 5" filter $25 and the same size 1" only $3??? Amazon price on these is the best I could find anywhere---even for generic brands of this size. When the filters arrived, they said 20x20x4 instead of 20x20x5 on the listing and on my order, so I thought, of course, that the wrong filter was sent. However the actual width of the filter is 4 and 3/8" ---exactly the same as the 20x20x5 Honeywell that I am replacing. Confusing to me when the 20x20x5 and 20x20x4 are the same filter. Bottom line is it fits well and seems to filter well. The cardboard cage could be a little sturdier, especially for the price, but other brands are just as flimsy. Also listing says MERV 11 in several places and MERV 10 under "about the item". It is a MERV 11. ### ⭐⭐⭐⭐⭐ up vote *by G***N on April 29, 2025* consistently good filters ## Frequently Bought Together - FC100A1011-5pk 20" x 20" x 4" Replacement Filter (Pack of 5) - Honeywell FC100A1037 20"x4"x25" Merv 11 Filter Media, Pack of 5 - Honeywell Replacement Media FC100A1003 - 16" x 4" x 20" - 5-Pack --- ## 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.sg/products/44772493-fc100a1011-5pk-20-x-20-x-4-replacement-filter-pack](https://www.desertcart.sg/products/44772493-fc100a1011-5pk-20-x-20-x-4-replacement-filter-pack) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-25*
