Abstract: Disclosed is a water purifier including a first storage cistern in which an inlet for flowing in water is formed, a second storage cistern for storing the purified water and having a nozzle at the outside thereof, and a filter constituted by a ceramic filter, a cartridge filter, and a mineral filter and installed to the inside of the first storage cistern and the second storage cistern to filter the water flown in the first storage cistern and make the purified water flow in the second storage cistern, the water purifier comprises a ceramic filter formed as a mixture by mixing the conventional used silicon dioxide with its particle size of 1˜100 micrometer with additionally one or two or more selected among silicon dioxide, tungsten, alumina (Al2O3), silver, zinc (Zn), white gold (PT), gold (Au), and titanium dioxide (TiO2) with nano particle size.

Abstract: A functional soap includes nanoscale platinum, gold, silver, organic germanium and organic selenium to prepare soap, wherein anti-bacterial, sterilizing, skin irritation relieving and skin moisturizing functions provided in platinum, gold, silver, organic germanium, and organic selenium are added to the washing effect of the conventional soap.

Abstract: The present invention relates to a method and an apparatus for manufacturing a heat exchanging fin unit and a housing unit in an air handling system with antimicrobial function, the aluminum coil fin unit and the housing unit being coated with metal nano particles including nano silver particles to have antibiosis, sterilization and antimicrobial functions. According to a preferred embodiment, the metal nano particles are mixed with a hydrophilic paint and a preventing paint to be coated on the surface of the heat exchanging aluminum coil fin unit. The nano particle is one or its mixture selected from the group consisting of Pt, Au, Ag, Cu and TiO2 and has a density of 1,000 ppm to 10,000 ppm and a size of 20 nm or less. Preferably, the nano particle has a size of 1 to 2 nm and a density of 100 ppm to 200 ppm to provide a high sterilization effect.

Abstract: This invention is on manufacturing method of antimicrobial and anti-fungus wet tissues with antimicrobial and anti-fungus whole cloth for wet tissue(i.e. non-woven fabrics, cottons and papers) manufactured with nano metal particles soak in tissue manufacturing water with nano sized metal particles which have antimicrobial and anti-fungus function to have multiple effects. According to this invention, woven fabrics, cottons and papers soak in the tissue manufacturing water that one or more than one of selected nano metal particles from gold, platinum, silver, germanium, selenium, zinc, copper and tungsten are mixed in the tissue manufacturing water and then they have antimicrobial and anti-fungus function.
