Our plume spray ensures optimum coverage so you have protection plus peace of mind . The Science The patented formula contains the 'silver bullet' ingredient, ELAH, which not only creates an invisible barrier that blocks viruses, it also disrupts the membrane around the virus so it cannot survive. It basically works in a similar way to hand soap. If your hands are dirty, you use soap to disintegrate the dirt so it can be washed away. If the virus cannot enter the cell, it therefore cannot infect.
