PuriPal is a human-powered portable water filter and container designed for outdoor use by hikers, campers, and survivalists. PuriPal’s reusable filter component removes contaminants, bacteria, and parasites through a multi-stage water filtration system including a micro-membrane pass, anti-bacterial ceramic plate, sustainably sourced activated carbon, and mineralising beads. Puripal’s unique design allows for human powered water filtration through a pumping and syphoning action.The bottle body is compressed and released to syphon unfiltered water through the intake at the base of the bottle, allowing water to pass through the multi-stage filter, leaving clean, drinkable water inside the bottle.
