DrinkPure is a product of Jeremy Nussbaumer student at the ETH Zurich Research Institute. The DrinkPure model only weighs 100 grams, one meter per liter of clean water, capable of supplying one person of fresh water in a year to be replaced.

Users only need to put water in a regular plastic bottle, attach the DrinkPure to the bottle mouth, tighten the screw so that the water does not flow out, slope the bottle back and gently squeeze the product will be clean water. Gizmag reports that the filtration process consists of three steps. First, large objects such as sand and plants will be trapped; Next, water passes through activated charcoal to deodorize and pollute the chemicals, and eventually the polymer membrane removes potentially pathogenic bacteria. Once filtered, DrinkPure will be removed, washed and reused.
