I have tried several DIY options to keep the draft and moisture out due to having my air conditioners. This is great. We've had some chilly nights recently and I'm just getting prepared for the fall/winter. So far So Good. Snug fit, no moisture, keeps heat in. Review: Still too early to comment on function but... - Fits great and was easy to get ready. Looks nice and seems durable for its purpose. We haven't had super cold or windy weather yet but it appears to block the bit of draft there is at this point but we're just finishing an Indian Summer before fall really starts to set in and then winter, which will be the real test, so if there's any problems with this not keeping the cold out this winter, I will update further. I'm in Wisconsin and we can get some brutally cold and ultra windy weather so we'll see what this cover can do... ## Features - 【Three Layers Of Insulation To Block Drafts】Unlike other single-layer covers, Tohonfoo window air conditioner cover use a three-layer structure: 600D waterproof heavy duty oxford material, 2mm thickened pearl cotton, insulated aluminum foil. - 【Perfect Fit】The inner size of the indoor air conditioner cover is 28"Lx20"Hx3.5"D, fitting most of 14000-24000BTU window air conditioners or indoor AC unit size of 26"-28"x 18"-20" x 3"(L x H x D).

It's a wall unit. The cord has no place to go with where it is positioned. It is a good idea overall, but it needs some design work. --- ## 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/740332397-28lx20hx3-5d-indoor-air-conditioner-cover-for-window-units-3](https://www.desertcart.tn/products/740332397-28lx20hx3-5d-indoor-air-conditioner-cover-for-window-units-3) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-13*
