Abstract: A disinfection tower adapted to receive current when in operation including (a) a support house having a space inside the house adapted to include an exchangeable current supply unit, wherein the house has an elongated shape having a circumference, a top part and a bottom part opposite each other, (b) multiple elongated UVC light sources adapted for radiating microorganisms, wherein each UCV light source is fixed and disposed outside the house at a desired distance from the circumference of the house and in a longitudinal direction relative to the house, and wherein each UVC light source is disposed with a suitable distance configured to eliminate overheating of each UVC light source.

Abstract: A self-disinfecting water trap for use in a washbasin having a drain including a housing having a top part and a bottom part defining an interior space adapted for maintaining trapped water. The top part has a first opening configured to engage in a liquid tight manner with the drain of the washbasin, optionally via a hollow inlet pipe, and a second opening configured to engage in a liquid tight manner with a hollow outlet pipe for discharging waste water. The bottom part is adapted to receive and maintain an UVC light source in a liquid tight manner, wherein the UVC light source when in operation radiate the trapped water and the total interior space.

Abstract: The present invention relates to air sterilizer unit having at least one inlet and at least one outlet comprising (a) a filter housing having an interior space wherein at least one UCV light source adapted for radiating microorganisms, is located, and at least one filter with a capacity to reduce or remove microorganisms from ambient air, wherein the filter is UVC resistant and is located between the UVC light source and the at least one outlet, (b) an air transportation unit, wherein the air transportation unit is adapted to move ambient air from the at least one inlet into the filter housing, and being exposed to the UVC light and through the at least one filter, and through the at least one outlet.
