High-touch surfaces are surfaces that are touched multiple times by different users during the day. Regular disinfection of these surfaces with UV-C light prevents the spread of harmful micro organisms by contact.
Examples of high-touch surfaces:
Desks, telephones, computer screens, keyboards, laptops, doorbells, door handles, light switches, control panels, buttons in elevators, handrails on stairs, walls, tables, beds, bathroom fittings, toilets, sinks, medical equipment and, instruments, training tools like mats and training equipment, ATMs, payment terminals, seating areas in cars, buses, trains, passenger planes and seats in movies theatres.
Touching surfaces contaminated with pathogenic bacteria and viruses is a source of numerous infectious diseases. Since every surface that has been touched or sneezed on by an infected person is in principle capable of transmitting the viruses.
Minimizing this risk is crucial, because research suggests that such as COVID-19 virus may live on surfaces for a few hours or up to several days depending on temperature, type of surface and humidity of the environment.
Our UVC handheld device is an excellent tool for UVC disinfection of all kinds of surfaces. When bacteria and viruses are exposed to a germicidal high-energy UV radiation with a wavelength of 254 nm, their DNA and RNA will be damaged and they lose their ability to reproduce and become virulent.
UVC-Dose (mWsec/cm²) = Irradiance (mW/cm²) x Exposure Time (sec)
The UVC-Dose (irradiance multiplied by the exposure time in seconds) should be at least 40 mJ/cm² in order to inactivate viruses, recommends the IUVA (International Ultraviolet Association) for a handheld UVC device for surface disinfection. So if the irradiance at the target surface is 10 mW/cm², the exposure time would have to be 4 seconds.
The UVC irradiance for certain distances from the bottom of our device UVC 150:

Usage: The unit via power cable may only be connected to a grounded 230 V (50 Hz) protective contact socket. While wearing the supplied safety glasses, switch the device on. Move the device slowly and firmly over the surface to be disinfected at a height so that the irradiance, multiplied by the exposure time in seconds results in the UV dose you want. When the disinfection is complete, switch off the device and keep it in a safe place.
Safety: CAUTION! UVC radiation is harmful to eyes and skin! The operator must wear the protective safety glasses provided with each R-FILTER device whenever the device is in use. The operator of the device must ensure that all his skin surfaces are covered while using the device.
The best kill rate of microorganisms is at 40-60% relative humidity and at an ambient temperature range of 21-24 °C.
