The materials we use for the filter reinforce our commitment to sustainability, quality and durability.A + B. The filter housing + the lever (filtered / unfiltered) are made of ABS and PC plastic, free of toxic such as BPA and phthalates, made of natural raw materials.
C. The casing is the part that covers the spare part (carbon block) and which has to be saved and reused every time we put in a new spare part. This part is also made of ABS and PC plastic, free of toxins like BPA and phthalates.
D. The refill (carbon block), the part that filters the water, is made of coconut shells (70%) that biodegrade into CO2 and water, and UHMW (30%) that is inert and stable and does not accumulate in marine life . We also use two small pieces of silicone to ensure that the carbon block remains in place thus ensuring maximum filtration efficiency. These decompose into amorphous silica, carbon dioxide, and water.
