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: Cuts Drafts from Small A/C - This is a great cover for a small air conditioner. Packing it underneath with foam and weatherstrip tape, it already has an aluminum lining that probably helps with cutting down any draft. Has velcro, so while it is not a custom fit, it fits neatly around the a/c and keeps the room warmer. Takes some work, but worth it! ## 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). Note: Please measure your unit before purchasing. - 【Velcro Make the Cover Stick Better】Our air conditioner cover for inside comes with pre-sewn velcro and adhesive-backed velcro for quick and secure attachment to your window air conditioner, ensuring a tight seal with no cold air leakage. - 【Reduce Heating Costs】The AC covers for inside wall unit will effectively block any wind and cold air from entering into the room to ensure that there is no heat loss, which can prevent heat loss in the winter to reducing heating costs. - 【Two Closable Cord Holes】Unlike many air conditioner covers that only have one wire hole, we have wire holes on both sides, and our wire holes can be closed to avoid drafts through the wire holes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D9MDPBBB | | Brand | TOHONFOO | | Colour | Grey | | Customer Reviews | 4.4 out of 5 stars 425 Reviews | | Included Components | Adjustable straps | | Item Type Name | Air Conditioner Cover Indoor | | Manufacturer | TOHONFOO | | Model Number | HF-ACCI-28-20-3.5-GY | | Number of items | 1 | | Part Number | HF-ACCI-28-20-3.5-GY | ## Product Details - **Colour:** Grey - **Brand:** TOHONFOO - **Item weight:** 381 g ## Images ![28"Lx20"Hx3.5"D Indoor Air Conditioner Cover for Window Units, 3 Layers Insulation AC Cover for Inside Wall Unit with Aluminum Foil and 2mm Foam, Windproof Window Air Conditioner Cover Inside, Grey - Image 1](https://m.media-amazon.com/images/I/81axLDS14hL.jpg) ![28"Lx20"Hx3.5"D Indoor Air Conditioner Cover for Window Units, 3 Layers Insulation AC Cover for Inside Wall Unit with Aluminum Foil and 2mm Foam, Windproof Window Air Conditioner Cover Inside, Grey - Image 2](https://m.media-amazon.com/images/I/7147RWq9G1L.jpg) ![28"Lx20"Hx3.5"D Indoor Air Conditioner Cover for Window Units, 3 Layers Insulation AC Cover for Inside Wall Unit with Aluminum Foil and 2mm Foam, Windproof Window Air Conditioner Cover Inside, Grey - Image 3](https://m.media-amazon.com/images/I/71n-XtWMh1L.jpg) ![28"Lx20"Hx3.5"D Indoor Air Conditioner Cover for Window Units, 3 Layers Insulation AC Cover for Inside Wall Unit with Aluminum Foil and 2mm Foam, Windproof Window Air Conditioner Cover Inside, Grey - Image 4](https://m.media-amazon.com/images/I/7141qz9ZPOL.jpg) ![28"Lx20"Hx3.5"D Indoor Air Conditioner Cover for Window Units, 3 Layers Insulation AC Cover for Inside Wall Unit with Aluminum Foil and 2mm Foam, Windproof Window Air Conditioner Cover Inside, Grey - Image 5](https://m.media-amazon.com/images/I/71xgjSvniOL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ No More DIY *by J***. on 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. ### ⭐⭐⭐⭐⭐ Cuts Drafts from Small A/C *by M***R on 30 December 2025* This is a great cover for a small air conditioner. Packing it underneath with foam and weatherstrip tape, it already has an aluminum lining that probably helps with cutting down any draft. Has velcro, so while it is not a custom fit, it fits neatly around the a/c and keeps the room warmer. Takes some work, but worth it! ### ⭐⭐ needs better designing *by X***O on 12 October 2024* This cover will not fit my a/c unit. 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.hr/products/740332397-28lx20hx3-5d-indoor-air-conditioner-cover-for-window-units-3](https://www.desertcart.hr/products/740332397-28lx20hx3-5d-indoor-air-conditioner-cover-for-window-units-3) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
