As an answer for the millions of people in the world without access to safe drinking water, Kohler has partnered with a selection of humanitarian aid groups to create Clarity. The streamlined filtration system can clean up to 40 liters of water per day. Its vessel is divided into two parts: an 11-liter holding tank for the water before it passes through a ceramic filter into a 12-liter reservoir below, enough space in between to avoid recontamination. The storage tank and dispenser are made from recycled plastic, and the filter has an estimated lifespan of one year.
