The technology used within the filter is called Electroadsorptive technology, the positive charge from the filter media attracts the negative charge in the contaminant cell like a magnet, this means irrespective of the particle size and the pore size of the filter media, the contaminant does not pass through the filter which is why it can remove the smallest of cells such as water borne viruses as well as bacteria etc, that tend to be larger in size.
The filters have a shelf life of 2 years and a in use life of 200 litres or 2 months. The filter can be cleaned and stored after use to prolong the life span.
