Features
- Fits Casement, Crank & Skylight Windows:Designed for casement, crank-out, push-out and skylight windows, this portable AC window seal kit fits window perimeters up to 300CM/118". A practical solution for homes and apartments where standard sliding window kits do not fit.
- Works with Single & Dual Hose Portable AC Units:The adjustable zipper opening wraps around one or two exhaust hoses, making it easier to vent different portable air conditioner setups. It offers more flexibility than rigid window panels with fixed hose ports.
- Helps Reduce Hot Air Backflow:By sealing the open window area around the exhaust hose, this AC window vent kit helps reduce warm outdoor air from flowing back inside. It supports more efficient cooling and helps keep your room more comfortable in summer.
- No-Drill Installation for Renters:No tools or drilling needed. Apply the adhesive hook tape to a clean, dry window frame, attach the seal, place the hose through the zipper opening, and tighten around it. Great for renters and seasonal use.
- Water-Resistant Fabric for Summer Use:Made with durable water-resistant fabric for everyday summer use. The flexible design helps create a neater setup than cardboard or tape DIY solutions and is easy to remove and store when the season ends.

Not easy to figure out how to use an ac unit in a window like this! We have an old house so these crank completely out. So both sides need to be sealed. It wasn’t difficult to install, just use the adhesive to apply all around the window frame and then velcro the plastic pieces together. It doesn’t look the most attractive from the outside but it’s better than dying of heat! There’s normally No leakage but if there is a heavy rain, the way it seals together on the top of the window creates a pocket… so it will start to get filled with water and can leak down the sides a bit. How to solve that is to raise it up making a pitch in the plastic so it drains off the sides so it won’t collect there. The zipper opens large enough to attach the hose through. It really is the best solution for this weird type of window. Ok, the only one! Haha

The one I bought was a bit too long. But it’s okay! Still functional. I bought this because the tape and box around my window didn’t look nice and it’s not weather proof. I like the flexibility of this item because if it rains all I have to do is remove it from the stick on Velcro and then re-apply again later if I want. Functionality: I like that it’s somewhat rain proof, and you can remove anytime and reapply if needed Stickiness: Make sure you follow instructions and clean your window seal well. Or else the Velcro adhesive will not stick.

The graphic on the ad implies there is a fixed form to insert two hoses. Actually it's just a series of zippers that lets you place the hoses in a convenient way. It does keep out moisture - as long as you make sure that the seal is tight on the tape side and the velcro side. Using the supplied zip ties helps to secure the zipper around the end of the hose, but self-sealing velcro tape wrapped around the end of the zipper to cover any opening helps to keeps insects out, and is less expensive to replace than zip ties. Reasonably priced, useful instructions and videos, likely to last several seasons.

Works very well, easy setup and great use out of it thus far. Keeps any bugs and birds out of my windows. Very soft fabric , white in color with mesh parts. There is no noise canceling to this but it definitely helped my finally install my AC to my weird apartment windows! I use it to install my Air Conditioner Hose for my apartment crank windows

I don't think you can reuse this thing, so I'll definitely buy this again next year. This thing saved my life this summer, and I installed it right before a heat wave; just in time! It did a great job of keeping the cold air in and the hot air out. It was a little tricky with the instructions that came with it, but I found a video from someone else in the reviews (I think) that really helped me install it. What I would recommend it to pay attention to the way the zipper is facing. I installed mine with the zipper facing out so it was hard to close.

Not thrilled about this purchase but it is serving it's purpose adequately. It is basically a shower curtain, with velcro & magnets. In saying this, it was more cost effective to purchase this product than a shower curtain, velcro & magnets. It is not in a high traffic area so it is holding up; no tears. Installation was easy & has also held up; continues to stay adhered to door frame. BEFORE YOU BUY.....if the product is going to be placed in a doorway where there is any kind of air pressure, DO NOT adhere it to the door to the point the plastic is tight. The plastic will need to have some give for the magnets to connect & stay connected. Even than, I have to leave the bottom magnets disconnected so the plastic doesn't open when the a/c kicks on. **You can see what I'm talking about in the pictures attached.

Over the years I have purchased several of these type screens but this is by far the best material and workmanship I've ever had. I logged on to order another one before the price goes up. I don't have a dog so I'm not trying to use it for something its not intended to be used for, and be disappointed. Its an alternative screen and that's what I'm using it for. I have a metal security door, so I attached the screen directly to the door using the supplied hook and loop tape (velcro), so far its holding up beautifully.
