PUR TAP, Florian Post, Lukas Braun, Weiso

PUR TAP is a water purifier made of bio materials for daily use. It removes residues of heavy metals and chemicals from tap water to make the CO2 emissions caused by plastic bottles unnecessary. The slip-casted filter is made out of clay and charcoal. When fired, the charcoal burns out and leaves fine pores that are also able to filter bacteria and viruses. As the water needs to go through the surface in order to get filtered, we increased the surface 75% to accelerate the process. The filter is able to purify up to 700ml per hour.
