The product has passed the "Zhong Nanshan Research Institute" virus killing detection test. Under the experimental conditions, the co-creation-Knokke deep-ultraviolet UVC anti-virus product has been in contact with E. coli, Staphylococcus aureus and influenza virus for a specified period of time, and it is more effective against pathogens Good killing effect. Irradiation for 30 seconds and 60 seconds can effectively kill E. coli (Table 1) and Staphylococcus aureus (Table 2), and irradiation for 2 seconds, 10 seconds and 60 seconds can effectively kill influenza virus and new coronavirus (Table 3). The killing effect has been certified by the authority.
