Duux is a Dutch company that has worked on solutions for air treatment for 20 years already. They focus on stylish products that spread clean and comfortable air throughout your home. With a Duux portable air conditioner, you get an A energy label air conditioner. Because the device is only made up of 1 part, you can easily place it in the space you want to cool. Always place your portable air conditioner close to a window or door. That's very useful, as the air conditioner carries warm air outside through a drain hose. Want to do it right completely? Use a window seal kit to keep the warm air out.
