Product was not a good fit over air conditioner and required added wrapping materials to close gaps. ### ⭐⭐⭐⭐⭐ No More DIY *by on Reviewed in the United States 19 October 2024* I'm from the Midwest and it gets COLD in the winter. 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. ### ⭐⭐⭐⭐⭐ Still too early to comment on function but... *by on Reviewed in the United States 10 September 2025* 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... --- ## 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/740332397-25lx17hx3-5-indoor-air-conditioner-cover-for-window-units-3](https://www.desertcart.jp/products/740332397-25lx17hx3-5-indoor-air-conditioner-cover-for-window-units-3) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-01*
