This water bottle lets you safely drink water — even when it comes from a dirty river.
“Purisoo” purifies water from natural sources to make sure you’ve always got clean water on you. But unlike bottles that only rely on a purifying straw, which can subject you to outlying bacteria, Purisoo filters the water you draw into it. It uses a triple-layer filtration system, so it keeps the water safe from contaminants in its reservoir on the other end, which detaches so you can drink without worrying. The bottle also features an extending tube that can get into hard-to-reach sources of water.
In terms of the longevity of the products filter, the Purisoo crowdfunding page states, “When you find that the amount of water being pulled through the filter has decreased per pump, it's time to change the filter. Wash the bottom of the filter occasionally - large particles are filtered by the fabric filter. The filter purifies up to 1,000 liters.”
Despite the power and efficiency of the device, it has a limited carrying capacity of 13.8 ounces. The product is currently crowdfunding on Kickstarter and are aiming to make drinking water much safer when you’re out in the wilderness.
