The idea behind the development of the WAATR PureMax 4D drinking bottle, with its technologically smart and high-quality design, was to purify water in an intelligent way. With the help of powerful dual UVC LEDs, microorganisms in the water are destroyed, even before they enter the filter. Subsequently, the special filter system – consisting of coconut charcoal and ion exchange resin – reduces particulate, chemical and metal contaminants in the sterilised water. The combined technologies for water purification, as well as the practical and stylish design of the triple-insulated aluminium bottle, impressed the jury.
