Eco-friendly solutions are the future and a water purify device is starting to be a must in a lot of places around the world. I like this particular one because of the cool design and the fact that can store up to 10 liters. I took a look at the link provided in the hunt and another big plus is the weight, with only 9.5kg so it's easy to be carry around without to much effort. Simple concept behind the project of the product but so important and esential. A product like this would have a huge impact in a lot of places around the world where water supply starts to be a major problem... Overall a great hunt that shows a great product!
