What renowned cold room hygiene experts say:

Diop distributes the DiosolGenerator nebulizer and Diosol disinfectants which have been extensively examined. For this purpose, the substance Diosol, which can be nebulized in various concentrations, was treated in accordance with DGHM guidelines and applicable European standards. Under production conditions, a virucidal and even sporicidal disinfection can be achieved. In in vitro tests a germ reduction between 90% and 99.999% was found."
