## Description

Review: 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.
Review: 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.

- 【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.

### ⭐⭐ Review
*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.
