Portable AC Hose Insulation Sleeve, Portable Air Conditioners Insulated Hose Cover Wrap, Fit 5" & 5.9" Diameter Exhaust Hose, Easy Installation with 3*Adjustable Buckle Straps, Light Gray

Excellent Performance & Easy InstallationTL/DR: Easy install and review includes tips for install, significant heat reduction, also block light which is unexpected but great for day sleeping!This cover works exceptionally well and is much easier to install compared to sleeve-style designs. To achieve the correct length, I carefully folded both ends back, ensuring the Velcro remained functional, and secured it with one of the included connector elastics. Those with sewing skills may prefer to trim the length and finish the edges for a cleaner look.Once the covers are in place, the hoses become more rigid and less flexible in terms of bending or extending. For best results, adjust the hose to the correct length before installing the cover. Position bends as needed before connecting it to the air conditioner or window vent.I immediately noticed a significant reduction in the heat radiating from the exhaust hose. Previously, the hose emitted warmth up to three feet away, but after installing the cover, I can no longer feel a difference between the exhaust and intake hoses. Additionally, the cover helps block sunlight, an unexpected but welcome benefit that enhances efficiency and allows for great day napping!IMPORTANT NOTE:There is a slight rubber odor upon opening. However, after hanging the cover fully open on a pants hanger outdoors for 24 hours, exposure to sunlight and fresh air effectively eliminated the smell. In contrast, another similar product has retained its chemical/rubber scent for five days. This cover offers a much better experience in that regard.

Fits on the vent hose as described and the hose stays much cooler. Works very well. Looks nose also.Fit:very good product.

This a/c vent hose cover is such a huge game changer. I didn’t even really know I needed it until I tried it. I have gone years without it and every year is the same thing. The heat going out of the vent makes the area around the a/c hotter. Which is opposite of what I am trying to achieve by using an a/c unit in the first place. Also, I have it next to my bed and I am a day sleeper. The light coming in from the hose made sleeping very difficult. Once I put the cover on and noticed what a huge difference it made, I was thinking about how dumb I have been to go every summer season without it. The room is much cooler and darker and the unit doesn’t seem to have to work as hard to cool the room down either. Which is beneficial to good sleep. So you might think you really don’t need it but I promise you that you do. It’s super affordable and easy to put on too. I won’t use another a/c unit without this hose cover!

nice product, fits well and with the reduction of heat from the exhaust hose it improved the efficiency of the unit to keep my home office a couple of degrees cooler vs without it at the same settings. The Exhaust hose measured about 110-115F before and now the measurement is in the low 90s. It was longer than I needed but I was able to fold the end back and using the straps that were provided this was enough to hold everything in place avoiding the need to cut or trim.

You need this for the vent tube for your portable AC. That big vent tube gets hot! You can feel it giving off heat, this product insulates that tube just like adding pipe insulation around a cold or hot water line. This keeps that heat in the tube and exiting out the wall or window. It’s long but Works PERFECTLY! I folded over part of it onto itself and used the included tie downs to hold it all together. Wish I would have bought it sooner.

The improved performance of my portable air conditioner was impressive. The unit now cycles off and on for the first time. Installation was easy. The cover was barely warm.

I think it makes about a 95% difference in the ac being able to keep the ambient temperature pleasant without the terrible temperature radiating from the ac exhaust hose. Product came in great shape and was delivered quickly. Neighbor was impressed. She bought one from this seller, too.

It works as advertised. Was simple to install and most importantly it keeps the heat from leaking into the room.
