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.

WOW! Night and day difference! Idk how I didn't have this for years. I replaced the tube on my portable AC and figured I'd try this. The tube used to heat my room and make the AC work twice as hard. Now after filling on high for the last 4 hours the insulated wrap is room temp and cool to the touch. Anything lis this is a must have for any portable AC

Why did you pick this product vs others?:This had good reviews so I thought I’d try it so far this is working just fine it’s a bit tight to get it around but I got it to fit much cooler in the room instead of the hot pipe omitting heat back into the room

Long enough for one portable AC's hose, not long enough for another portable AC's hose.For the other portable AC's hose, I had to get an additional shorter version (Cestluck Portable Air Conditioner Hose Cover Wrap) to finish covering it.But other than that issue with it not being long enough for some portable AC hoses, it works fine at limiting the heat from the output of the air conditioner that stays inside the room.

Works as should. It is a little rough to get on but don't give up once on it fits great and does what it is supposed to

Larger than I thought they'd be. Its not hot enough to use my ac right now but I think when I do get to use it, these will work great. Nice thick material. Great length. They have velcro plus 3 straps so it should stay on very well. Will try to give an update when I finally get to use them.

It does exactly what it says it does. it covers the tube and blocks the heat from escaping. my tube is very badly designed, looking at your toshiba, and this thing, while tight around the tube, works perfectly.

This works really well! No more light coming in through the exhaust tube. No more heat escaping back into the room from the exhaust tube. Installation took less than 5 minutes. Definitely recommend for darkening the room and keeping the room cooler.
