Answers to your questions

  • Our filter combines a 0.5-micron membrane with powdered activated carbon. The membrane retains all particles larger than 0.5 microns that may be present in the mains water, such as traces of heavy metals, colorants and drug residues.

    The activated carbon powder, suspended at the bottom of the filter, retains the chlorine present in the mains water by adsorption (the chlorine molecules attach themselves to the activated carbon).
