AGPTEK300cm Window Seal for Portable Air Conditioner 118 inch Mobile AC Unit Soft Cloth Sealing Stop Hot Air with Zip and Adhesive Fastener-no Need for Drilling Holes for Tilt Window

Good

For portable AC that don’t come with a solution for tilting windows these are great and allow your unit to pump out hot air. This is exactly 300 cm standard size. If you have all white windows like mine they are practically invisible. The best part is when you are ready to close the window they do not get in the way or you can rip them off the velcro. This is a super well executed product. The only weakness is that they are not sound isolating at all but they can’t do everything.

This seal was extremely confusing to install and the instructions were not helpful. I had it up for about a month and its been okay (the zipper does not seal all the way to the vent so there's a small gap). However, it rained for the first time yesterday and the window seal let in so much water, there was a puddle on the bottom piece about to spill into my room. This was not due to consistent rain or wear and tear. My seal is basically new and absolutely not waterproof. Now I have an AC machine I cannot use because this seal lets rain into my room

This works awesome, easy to install. And seals tight around the window. Wish it was a dark color to keep out the sun but it keeps the room cold and that's what matters!

Item came fast, Installed in storage window so there's a lot of extra that I had to roll up and tuck away, other than that it does the job. Zipper fits very snug around ac hose so, so far happy with the product. Only have been using one week so stay tuned, will update if needed

Not horrible but not necessarily the best. Installation isn’t the best. The paper instructions were horrible. Had to watch the video on exactly where to place the Velcro on window. But still even with the proper size it did not fit my window correctly. The side attaching to the window was longer and the side attaching to window sill was to short (yes I tried both ways and yes I tried different sized products as well). Probably will buy some plexiglass instead or just tape up the gaps to get buy.
