In hospitals, offices, government buildings, airports and health care centers rooms and surfaces are disinfected. This can be done by UV-C light which inactivates bacteria and virus like Covid-19. In more and more locations so-called 'UVC Towers' are used. These devices can be placed in a room, activated and some minutes later the surfaces that are radiated with the UV-C light are disinfected.
ClearSafeProducts has conducted a comparison study on these 'UVC Towers'. We compared professional products, listed the different technical specs and evaluated these products. From our study the EFSEN UV TOWERx8 is the Best Buy.
In addition we provide some practical tools for the end-user of these UVC Towers to calculate the time required to reduce Covid-19 with 99.9% (log3 reduction). A time/distance table is shown in the document and guidelines are provided on calibration of your own situation by using dosimeter cards.
Caution: while these UVC Towers operate, no human beings or animals are allowed in the room. Therefore all units are equipped with motion detectors that switch off the device instantly when movement is detected. Operators who work with UV-C towers are nevertheless advised to wear proper clothing against UV-C, just in case. See the user safety manual for more information.
