Sanyo’s Virus Washer air purifiers are effective against the spread of the swine flu virus, because they use electrolysed water, Japanese researchers have found.
The Gunma Prefectural Institute of Public Health and Environmental Sciences found that electrolysed water reduced the ‘infectivity’ of the H1N1 virus by 99 per cent or more, compared to ordinary tap water.
Sanyo’s technology creates electrolyzed water by passing electricity through tap water, avoiding the need for any additional chemicals.
The Gunma researchers said that the viral protein is broken down by a reaction with the two types of active oxygen present in electrolysed water, destroying its ability to adhere to human cells.
The Virus Washer technology, which cleans the air of airborne microbes and particles also showed an equivalent effeciveness against seasonal flu and bird flu.
The Washers, available in domestic and commercial versions, can use fan speeds of up to 600 m3/h, enabling the air to be circulated over three times per hour in a typical school classroom, the firm said.
