Disinfection devices are tools designed to eliminate harmful microorganisms, such as bacteria and viruses, from surfaces and air. Common types include UV-C light devices, chemical sprayers, and ozone generators. These devices are widely used in hospitals, schools, and homes to maintain hygiene and prevent the spread of infections. Many disinfection devices operate using different methods. For example, UV-C light works by damaging the DNA of pathogens, rendering them inactive. Chemical sprayers apply disinfectant solutions, while ozone generators produce ozone gas that can kill germs. Each device has specific applications and effectiveness depending on the environment and type of contamination.
