The A.R.I.A. are air treatment systems with UV-C LEDs that act on the inhibition of cell replication of microorganisms in order to interrupt reproduction.

Tests conducted on A.R.I.A. 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 *.

The products have been subjected to microbiological and safety tests at certified control bodies. The checks were carried out to ensure the tranquility of use for buyers and to be able to give examples of references to guarantee the effectiveness of use.


The verification of the germicidal activity was conducted following the method of the technical standard ISO 15714: 2019.

The results obtained on the gram negative bacterium Haemophilus Influenzae and on the H1N1 virus appear to have identical abatement curves, both on instant sampling (98%) and on one-hour recirculation (99%).


This functional efficacy test was conducted on the microbial load, present in any common environment, and is used to evaluate the abatement that is recorded in each aliquot of air that passes through the A.R.I.A. sanitizer duct.

The air, contaminated with mixed colonies of pathogens, is sanitized by 72% at each passage, therefore if the same amount of air passes a second time inside the sanitizer it will be sanitized to 92%, at the third passage of 97.7 %, and so on. This guarantees greater and greater disinfection over time.


The product was tested in the accredited laboratories to assess whether there were photobiological hazards for people who use this device both daily and occasionally.

In relation to the safety of UV-C emission, the A.R.I.A. meets the requirements of EN 62471:2008.


The EMC tests consist in verifying the functionality and safety of household and similar electrical appliances. The CEI EN 60335 standard confirms the requirements for the safety levels of electrical appliances at an international level against electrical, mechanical, thermal and fire hazards of the appliances and against the interference of electromagnetic phenomena that can interfere with correct operation and safety.

The OCE company performed these tests on A.R.I.A.


The difficulty of being able to directly test the Sars-Cov2 virus (better known as Covid19), forces us to use all the information found through the scientific documentation produced in the last year, in order to have references about the susceptibility of this pathogen to UV rays -C.

In support of these considerations, some important documents help us in determining how to be effective against this virus while maintaining values within the ranges established by the competent authorities:

  • UV-C irradiation is highly effective in inactivating and inhibiting SARS-CoV-2 replication – AA.
  • CIE Position Statement on Ultraviolet (UV) Radiation to Manage the Risk of COVID-19 Transmission.
  • Rapporto ISS COVID-19 n. 25/2020 del 15/05/2020.
  • ISO 15714:2019 Method of evaluating the UV dose to airborne microorganisms transiting in-duct ultraviolet germicidal irradiation devices.


UV-C LEDs emit at 275 nm, at this wavelength the radiation does not generate Ozone. Indeed, the tests in the literature show that this wavelength has the ability to destroy the ozone molecules by converting them back into oxygen.
