The tap filter is filled with oil-remove bio ceramic ball produced by MUQI.  Oil Remove Ceramic Ball is made of natural mineral materials which can release far infrared and negative ions energy. Such energy can shock Macromolecules of water into small molecules and decrease the surface tension of water. Meanwhile the energy can improve water penetration and solubility so water can cut into the interface of oil and dinnerware quickly. Accordingly water can cut off oil rapidly and have the oil separated from dinnerware surface easily.
