The Clair-IU small portable steriliser can be used to create an environment that is free of viruses and dust. The mode of operation is based on two technologies: on the one hand, the device is equipped with UV-C and UV-A LED lights, which enable effective sterilisation. On the other hand, the ambient air can be freed from germs and dust by means of CPI technology (Clair Plasma Ioniser). Both functions can be conveniently controlled via the round switch on the face of the device.
