Lukas Jager's 'Puur Zuiveren' is a natural and inexpensive filtration system requiring no specialized equipment.
The process of water purification usually requires a large amount of equipment and labour, as well as time and resources. Dutch designer Lukas Jager has developed a purification system that bypasses traditional means of filtering water, called ‘puur zuiveren’ which means ‘pure purifying.’
The system consists of a series of ceramic bowls sitting on plywood stands. The bowl is made of a clay and sawdust mix that is fired at 850 degrees Celsius. The sawdust burns away during firing leaving behind pores in the clay that make it ideal for purifying liquids at a fast rate. By adding colloidal silver, remaining traces of bacteria are killed, extending the shelf life of the final product.
