Without revealing our manufacturing secrets, and unlike most carbon filters sold under different brand names and composed solely of activated carbon, our filter is a complex assembly of several elements. Our composite filter provides effective filtration of most of the potentially dangerous pollutants present in water.

The filter is moulded from very high quality activated carbons, all NSF certified®, it contains silver ions for their bacteriostatic properties, as well as a specific material that improves the adsorption of heavy metals, also NSF certified. Finally, it incorporates a special nanofiltration membrane that works in conjunction with the other processes to treat a wide range of pollutants, including bacteria and viruses. This material was originally developed by NASA to solve the problem of water filtration in spacecraft. It tracks down the smallest molecules, right down to viruses, and its characteristics enable it to filter particles down to 0.001 micrometers (nanofiltration). This component is also NSF® certified.

Other parts of the filter

• The plastic parts of the filter are made from food-grade polypropylene, free from BPA and phtalates. This plastic has been assessed by an independent laboratory and has passed the REACH and ROHS (Restriction of Hazardous Substances) assessment aimed at limiting the use of ten hazardous substances: Lead, Mercury, Cadmium, Hexavalent Chromium, Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE), Bis(2-ethylhexyl) phtalate (DEHP), Butylbenzyl phthalate (BBP), Dibutyl phtalate (DBP) and Diisobutyl phthalate (DIBP).
• The silicone used in the joints is food-grade, and has passed REACH and ROHS assessments.
• The glue used to assemble the different parts of the filter is food-grade, and has also passed REACH and ROHS assessments.

Our Ultimate Star Filter® has successfully passed the REACH assessment and is NSF® certified. We can therefore guarantee flawless efficiency and safety of use.
