With a temperature of above 90 Crystal Bio is a special, environmentally friendly filter-media that produces a hyperconnecting glass cell structure. This results in media that have a surface area that is at least ten times larger than typical plastic substitutes. Furthermore, compared to other porous filter media, the weight is incredibly light: The weight of 100 litres of Crystal Bio is 15 kilogrammes. Above the filter media, the Shower Filter can alternatively be ordered with a built-in 300 micron stainless steel sieve. The 50-litre Crystal Bio media is included with this version of the Shower Filter.
A 90mm sieve waste outlet is also included in the PE housing.
