The materials we use for our filters reinforce our commitment to sustainability, quality and durability.
The cartridge housing is made of PLA plastic free of toxins such as BPA and phthalates, made from natural raw materials.
The carbon block inside the cartridge housing that filters your water is made from coconut shells (70%), which biodegrades into CO2 and water, and UHMW (30%), which is inert and stable and it 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 filtering efficiency. These decompose into amorphous silica, carbon dioxide, and water.
