The San-O3-Wash System is the only system on the market that's clinically proven by two independent laboratories to eliminate more than 99 percent of super bugs in the wash with use of patented Interfusor. Super bugs are bacteria that are resistant to the antibiotics used to treat them. As a result, the system helps prevent the spread of infections caused by super-bug bacteria and many harmful viruses, including but not limited to Hepatitis, C.diff, aspergillus niger, HIV and MRSA. While chorine bleach can only be utilized in one step of the wash cycle, ozone's oxidation power is utilized whenever water is present. It is a powerful and natural biocide - destroying bacteria, deactivating viruses and controlling odors.
