VIVOSUN 6 Inch 25 Feet Flex Air Aluminum Duct for Ventilation, 2 Clamps Included, Long Heavy-Duty Multi-Layer Dryer Hose Vent Kit, Duct Fan Systems

I got two of these air ducts for my basement ventilation. My house has no Radon mitigation system, so I want to use a simple way to ventilate the basement. A window fan blows air out at one basement window, and fresh air comes in from another window. But the windows are too close to each other, so I have to use air ducts to let the fresh air to travel about 40ft to the other side of the basement so that the whole space is sufficiently ventilated. I connected two ducts to reach the length. I used hanging straps to hang the duct to the ceiling wood so it's out of way. Now the radon detector shows the level fluctuates between 4 to 9 in the basement. Before ventilation, it reached 20 to 50! The living spaces upstairs has radon levels ranging from 0.2 to 1.0 most times, well below the 4.0 threshold.The side effects of the diy ventilation method is the lower basement temperature in winter (around 50 F) and higher humidity in summer (I run a dehumidifier in basement anyway, only that the electricity use is up).Back to the ducts, they are flexible, easy to expand and shrink in length, easy to install, the aluminum foil is thick. The price is reasonable.

Works perfectly. Price was right. No complaints.

This product is an excellent choice for bathroom fan venting. After remodeling my bathroom, I can confidently say it performed exceptionally well! It's not only easy to use, but also budget-friendly. Highly recommended!

I used this for a vent fan in my shed. It was just the right size (diameter and length) for my intended use. It was just the right thickness and only time will tell if it is durable as it in installed in the attic of my shed.

I used this in conjunction with a sleeve and was able to repair my ducting like it was brand new. I’m very pleased with how easy and clean it was to put the rings on and the connectors. I would recommend this to anyone trying to repair their duct for mishaps and only need up to 5 feet instead of buying a whole new duct.

Great Deal
