Gelt International<\/a>, scientific consulting company, has checked, as external auditor, the performance of one copy of MA-FER Impianti srl\u2019s air-purifier device, performing microbiological and chemical analysis.<\/h4>\n

Hurricane <\/strong>system is composed by several air-treatment modules: a pre-filter<\/strong>, a UV-C chamber<\/strong>, a photocatalitic filter<\/strong> and a HEPA filter<\/strong>.
\n<\/span><\/p>\n

The scope of the test is to verify the efficacy of the entire system in reducting the airborne microbial populations. The test involves to nebulize three microrganism (rapresenting Gram + bacteria, Gram -bacteria and fungi) in the air entering the copy of the device and verifying their reduction in the outgoing air.<\/span><\/span>
\n<\/span><\/p>\n

In addition, to check the germicidal activity of the UV-C chamber alone, a test was performed by removing the other air-treatment modules and letting the air flow through the copy of the device with only the UV-C light running.<\/span><\/span><\/p>\n

Results<\/h4>\n

The copy of Hurricane<\/strong> device by MA-FER Impianti was tested with 3 different microorganisms:<\/span><\/p>\n

    \n
  • Serratia marcescens<\/span><\/strong> as per Gram-positive bacteria. Tested also with the UV-C chamber alone<\/span><\/span>;<\/li>\n
  • Bacillus subtilis <\/span><\/strong>as per Gram-negative bacteria;<\/li>\n
  • Cladosporium sphaerospermum <\/span><\/strong>as per fungus.<\/span><\/li>\n<\/ul>\n

    From the results obtained by testing the entire Hurricane system, it has been verified that the copy of MA-FER Impianti srl device is able to decrease the microbial airborne populations with reduction higher than 99% for all tested microorganisms.<\/span><\/span><\/p>\n

    The test with the only UV-C chamber working, as per ISO 15714:2019 Method of evaluating the UV dose to airborne microorganisms transiting in-duct ultraviolet germicidal irradiation devices<\/span><\/em><\/span>, show that the ultraviolet dose emitted by the copy of MA-FER device is able to inactivate the test microorganism (<\/span><\/span>Serratia marcescens<\/span><\/em>), representing microrganism with D90 <25 J\/m2. Theoretically it is possible to point out a list of microorganisms<\/span> which, on the basis of literature data, can be inactivated by the same system<\/span>, including coronavirus*.<\/span><\/span><\/p>\n

    The graph below show some of these microorganism (data are taken from ISO 15714:2019 – Annex C).<\/p>\n
