Amashubhu e-UVCabe namaza wamaza e-UV amafushane kakhulu (200-280nm) futhi ngaleyo ndlela ayingozi kakhulu.Ngenxa yalokho, kufanele kuthathwe izinyathelo zokuphepha ezengeziwe lapho kusetshenzwa futhi kusetshenziswa lezi zinhlobo zezibani ze-UV.Imisebe ye-UV ekhishwa yila mashubhu okukhanya iqondise ku-DNA yamagciwane, okubangela ukufa kwamangqamuzana noma ukwenza ukuzala kungenzeki.Akulona uhlobo lwamashubhu okukhanya okufanele asetshenziswe ekhaya.Asetshenziswa kakhulu kuzilungiselelo zochwepheshe nezimboni ngezinqubo ezinjengokuhlanza amanzi, ukubulala amagciwane, ukuvala inzalo, nokukhucululwa kwendle kokudla.Ngokungafani nezibani ze-UVA,amashubhu e-germicidalngokuvamile zisobala.Gqoka izingubo zokuzivikela lapho ubambaIzibani ze-UVC ezibulala amagciwanefuthi uwagcine kude nesikhumba sakho namehlo akho.Kungcono ukugwema ukuchayeka isikhathi eside ekukhanyeni lapho kusebenza.
