A.R.I.A. UVC LEDs are air treatment systems with UV-C LEDs. Each model has been tested in accredited laboratories to evaluate the microbiological abatement, the photobiological aspects and the effectiveness of the device. To evaluate the reduction of the microbiological load of the air, the percentage abatement at the exit of the product was monitored, after exposure to internal UV-C LEDs, according to ISO 15714: 2019. Tests conducted on Fuocofreddo Led UV-C products included different types of microorganisms (indicated in blue in the graph). The results obtained in the laboratory guarantee efficacy for other microorganisms which, according to scientific literature, require lower doses (indicated in gray), including Coronavirus
