REDTRON Window Seal for Portable Air Conditioner（400CM）,Airlock Window Seal for Mobile Air Conditioning Unit and Tumble Dryer, Cloth Sealing Plate with Zip and Adhesive Fastener-No Drilling Holes

I purchased the 400cm size. It was easy to put up and it sticks very well to my old wooden window frame that has peeling paint. If you have windows like mine I suggest you scrape off the excess paint first and then wipe your surface down with a damp cloth or vacuum it before placing the sticky velcro on. My window is a bit smaller than the amount provided so I overlapped it on the top. My window is old fashioned, with a leaver at the bottom that pushes only the bottom outwards. This AC window seal works perfectly. No more bugs coming in and it's catching the ones trying to escape. It doesn't let hot air back in and still feels more fresh than a piece of plastic. Zipper and ties work very well too. They hold the AC hose perfectly in place.

Best cover.

The screen fits almost perfectly it’s quality material especially for the price. The only issue is that the zipper is on the wrong side so I have to reach my hand through to the other side to open and close it and the struggle is real a lot of the time. But my place is nice and cool and bug free so the pros definitely outweigh the cons. This screen has fit my door the best out of all the screens I’ve been through ( which is alot because zippers break and a neighbors cat kept spraying my door)

Once installed (which can take a little bit of time and figuring out), these kits operate great and nice for someone like me who didn't want to get into plastic/wood units for the windows. We replace them each year, as I don't feel they'll last multiple years (at least in our environment), but at the cost they're well worth it.

The correct size fits too tight and easily falls off.
