The filter module contains two highly efficient components: the patented AQUALEN™ microfiber and activated carbon fiber. Activated carbon has a significantly higher filtration performance than granular forms at the same volume due to its fibrous structure. The selectivity of AQUALEN™ microfiber towards heavy metals is utilized not only for filtration but also to prevent the development of bacteria inside the module. AQUALEN™ keeps silver in its active ionic form. This silver effectively prevents the growth of bacteria in the module, while it is not washed away by water and does not harm the human body. A water bottle with a filter is a step towards responsible use of our planet's resources and daily savings on the purchase of single-use plastic bottles.
