PURPOSE: To provide a photocatalyst system into which a cleaning device of air cleaner and a purification device of water purifier are integrated to perform two functions, air cleaning and water purification, at the same time and clean a large volume of air in a small sized space. CONSTITUTION: The photocatalyst system for water purification and air cleaning comprises an air cleaning device comprising a first filter(1) for filtering dust having large particles, pollen and so on from air passing through a suction unit(a), a second filter(2) for adsorbing fine dust, bacteria, etc. that are not filtered by the first filter, photocatalyst filters(3,5) for adsorbing harmful organic chemicals, bacteria and so on so that they are decomposed by oxidation-reduction reaction, ultraviolet lamps(4) for activating chemical reaction of photocatalyst and having disinfection function, and a third filter(6) and a fourth filter(7) for repeating air cleaning function and sterilization function again so that air(b) passing through an outlet contains 320 ppm or less of carbon dioxide; and a water purification device comprising a first filter(8), a second filter(9) and a third filter(10) for adsorbing heavy metals, microorganisms and harmful substances from water(c) passing through the water pipe, and a photocatalyst glass tube(11) on which titanium dioxide having sterilization and self-purification function when it receives ultraviolet rays is coated, and of which titanium dioxide carries out oxidation-reduction reaction to decompose other harmful organic compounds by ultraviolet rays irradiated from ultraviolet lamps(4) when water passes through the glass tube, wherein the photocatalyst glass tube is formed in a spring shape to perform air cleaning function at the same time by reducing flow rate of water passing through the photocatalyst glass tube and sufficiently irradiating ultraviolet rays of the ultraviolet lamps onto the photocatalyst filters.
