  • TiO2

    Titanium oxide

    Titanium oxide image

    This material decomposes proteins such as bacteria, viruses and odors into harmless substances.

  • HAp


    Hydroxyapatite image

    This material absorbs the bacteria and viruses, and will not release them.

  • Ag


    Electrode image

    The silver is the electrode that speeds up the titanium oxide during the decomposition process.
