The invention enables a certain amount of water (sufficient for personal use) containing microorganisms harmful to the human body (bacteria, viruses, etc.) to be cleaned from harmful microorganisms with ultraviolet light and make it drinkable.
In the patent application numbered TR202000964, "System Providing Cleaning of Screens of Digital Devices by Ultraviolet Rays" is explained. The invention relates to a system that enables the disinfection of harmful microorganisms on devices such as mobile phones and tablets (rechargeable screen devices) with ultraviolet (ultraviolet) rays in a very short time.
In utility model application numbered TR202005613, "Controlled and Time Adjusted UV-C Irradiation Sterilization Device" is explained. The invention is the device that has autonomous technology providing irradiation emission in UV-C standards has the design of providing the electrical operation of UV-C lamps located within the lamp unit mounted on mechanically extendible and relocatable, mechanically angular locatable plastic and metal stand by means of providing electrical energy to the device through the electric energy unit, and of starting or stopping the device in a controlled manner according to the sound, distance, movement perceived by the sensors of the sterilization device for which the signal communication of the screened, wired and wireless or mobile application controlled, electrically connected with the key set unit, function adjusted, programmable, time adjusted electronic control unit is ensured, and it is an automated robot system that ensures sterilization by emitting irradiation, which has UV-C irradiation technology through integrated system having mechanic and electric connection, to the surface with height and location setting and to the area at the required location with the handle of the robot, destroying the nucleic acids and through the irradiation of the wavelength between 200-280 nanometre range and inactivates the DNA’s of viruses and microorganisms by breaking and killing them, providing sterilization having UV-C irradiation technology of ultraviolet germicidal irradiation (UVGI) technology. In the applications discussed above, disinfection systems using UV-C light technology are mentioned. These applications generally carry out the disinfection of public living areas such as homes, offices, restaurants, halls, banks, airports, travel terminals, vehicles, elevators, public transportation, workplaces and water resources. However, since the UV-C lights used in these systems cannot be applied directly to the human body, they cannot fully provide sterilization.
As a result, there is a need for a new technology that can overcome the disadvantages, that does not cause any harm to human health, that prevents the spread of the epidemic, that is easy to use, can lit at certain intervals, and can be remotely controlled.

Detailed Explanation of Invention
The method subject to the invention offers a solution with the aim of limit the spreading of epidemic diseases. In this method, the direct application (40) of an already existing narrow ultraviolet light spectrum called far-UVC to the human body has been proposed. The light source (1) that is in the wavelength range of 200-222 nm, which has obtained as a result of filtering the far-UVC rays produced by excimer lamps, does not have any side effects due to its being at a level that will not harm the human body.
Far-UVC rays can kill all kinds of microorganisms due to their short wavelength and high energy. The antimicrobial activity of the far-UVC light without harming human beings is in the region in the wavelength range of 200-222 nanometers. This wavelength is the wavelength most effectively absorbed by DNA. UV radiation energy absorbed by cellular DNA forms thymine dimers by forming chemical covalent bonds between adjacent thymine bases. These emerging thymine dimers constitute the main mechanism of cellular UV damage. Thymine dimers formed due to this UV cause folding in DNA strands and the natural helical structure of DNA is disrupted. In this way, the spread of epidemics such as viruses whose DNA structure is disrupted can be prevented. It can kill viruses in the air without damaging human tissue due to the low UV dose of 200-222 nanometer wavelength range as a result of filtering the far-UVC rays.
In an alternative arrangement where the invention can use, the far-UVC light source (1) in the cabin located at the entrances of the communal living areas is provided the person to enter the building without causing any harm to their bodies by disinfecting the persons who enter the building. Here, the light source in the cabin is mounted in such a way that it does not create a shaded area and is applied directly (40) to the body of the person with 360 degrees movement inside the cabin. The far-UVC light source (1) used is integrated into the circuit board (3). Also the light source is becoming activated (20) by detecting sensor (2) due to detecting of people (10) and its lighting time is determined (30) by time module (4). In this way, the Far-UVC light source (1) in the wavelength range of 200-222 nanometers is applied directly (40) to the human body.
