VIVOSUN Window Duct Kit, Portable AC Window Seal Kit with 5.9" Diameter 59" Length Hose, Fit with 4"/6" Ducting for Sliding Window, Adjustable AC Vent Kit for Duct Fans, Air Conditioner, Dryer

The VIVOSUN Window Duct Kit is perfect for my needs. It's easy to install, well-constructed, and effectively manages airflow. It fits securely in the window and helps maintain proper ventilation. Highly recommended!

I was really skeptical that this window vent kit was going to work. Most portable AC units have horrible window vent kits and the one I had was driving me crazy. It was being held together by foam and tape. It looked horrible. The VIVOSUN window vent kit was easy to set up, and it fit in my window easily. There was only a small gap between the kit and my window, but the adhesive tape that they sent me fixed that issue right away. Now my window is sealed and I don't have to worry about air escaping or coming in. IMO this item deserves 5 stars.

Perfect replacement for the Hisense components. Easy to install and does exactly what I need.

I am a big fan of anything vivosun produces so it was no surprise that I loved this product! We make and works perfectly! I highly recommend this product!!

Works like it should. Good quality.

What can go wrong with manual of such a simple device? everything. the manual is rubbish. and since i am not a home builder, i have no clue what the weird half tape is for. And the manual just shows a weird dash lines. it is full of icons that have nothing to do with the steps. The item itself doesnt fit my window, it is right too big for two panels, and too small for just one and the slider behind. Would not buy again.

"Absolutely impressed with the VIVOSUN Window Duct Kit! Installation was a breeze, thanks to the adjustable design that seamlessly fit my sliding window. The 5.9" diameter, 59" length hose provided a snug and secure connection to my portable AC unit, ensuring efficient cooling throughout the room. I particularly appreciated its compatibility with both 4" and 6" ducting, offering versatility for various setups. This kit is a game-changer for anyone in need of a reliable solution to venting their AC, dryer, or duct fans. Five stars without a doubt!"

This would've been better if it came with a clamp for the hose instead of having to purchase one separately. I would've much rather had that than a third extender piece.Also, while they do include a lot of extenders, they ended up being way too long to fit properly, or just a hair too short without any of them. If the hole had been in the center or on a smaller piece, I could've fit a second extender and made it much more secure but that wasn't the case.Something that bothers me about this set, is that there isn't any way to lock the pieces in place once you have them where you want them. Pretty much anyone could walk up to your window, slide the pieces together, then easily pull it out of the window, and break into your house.I had to add a bunch of extra wood screws to try and stop the pieces from sliding, but that looks bad, wouldn't stop someone if they were determined enough, put unnecessary holes in my window frame, and still leaves me feeling a little paranoid at night.Overall, the quality felt more like something you'd buy from Dollar General or Big Lots and not anywhere close to where it should've been for almost forty bucks after tax. Like, this is barely sturdier than laundry basket plastic. I have ten dollar storage totes that are more rigid. Again, adding in a second extender would've helped, but it's not possible with the hole placement on the main piece.

really useful

ive used those other air conditioner window kits and this one is just better. very happy with this, and would suggest for summer exhaust needs.

merci

the description says it fits a 16.9" window so I figured my 18 inch window would be fine. Unfortunately where the hole is cut, several inches from the bottom, it makes it impossible to slide up an extender enough so that its not covering the hole. Right now one piece leaves a 1 inch gap at the top. I'll have to return this and keep searching.
