L’Università di Modena e Reggio Emilia (UNIMORE) ha condotto due differenti studi, uno sull’inattivazione delle cariche virali attraverso l’utilizzo del vapore Gioel ed uno sulla capacità di rimozione degli inquinanti da parte di Gioel Air. Puoi consultarli entrambi qui sotto, scegliendo la relativa scheda.

Per la sperimentazione è stato utilizzato:
- il virus influenzale sottotipo A/H1N1, ceppo WSN/33, derivato dal virus responsabile della pandemia di Spagnola del 1918 e filogeneticamente correlato con il virus pandemico del 2009.
- il virus Echovirus 7, appartenente al genere Enterovirus, molto resistente nell’ambiente e trasmesso per via alimentare. Alla stessa famiglia appartengono i Rhinovirus, responsabili di infezioni delle prime vie respiratorie.
Sono state effettuate prove preventive – prima del trattamento con il sistema Gioel – sia su una superficie dura (acciaio), che su una superficie porosa (tessuto naturale di cotone), per verificare la capacità di mantenere inalterata l’infettività virale.

Il trattamento a vapore con il sistema Gioel, ha portato alla completa inattivazione dei virus presenti. Anche l’acqua di scarico del cestello si è dimostrata priva di virus infettante, suggerendo quindi che non sono stati semplicemente aspirati e poi trattenuti nell’acqua, ma inattivati dal calore.
L’inattivazione è avvenuta su due superfici di largo impiego come l’acciaio (superficie dura) e il cotone (superficie porosa). Inoltre le cariche virali sperimentali utilizzate erano ben più elevate rispetto a quelle che si possono naturalmente trovare sulle superfici ambientali.
La possibilità di pulire ed igienizzare con filtro ad acqua rappresenta quindi una pratica igienica alternativa di basso impatto ambientale che elimina i rischi legati all’utilizzo di prodotti chimici.
Gioel risulta essere di particolare utilità sia a livello domestico che in ambienti comunitari quali alberghi, ospedali, case di riposo, senza dimenticare il suo possibile utilizzo per la sanificazione dei mezzi di trasporto pubblici e privati.

La Prof.ssa Paola Borella, Responsabile della Ricerca all’Università degli Studi di Modena e Reggio Emilia, ha condotto uno studio sull’efficacia del sistema vapore-aspirazione con filtro ad acqua Gioel nella riduzione dei contaminati ambientali quali l’inquinamento microbiologico (uomo, animali, polveri, strutture e servizi degli edifici) e chimico (smog esterno, prodotti da suppellettili, vernici, oggetti nelle stanze).
