Lab test results demonstrated the ActivePure® Medical Guardian, model F170A device using ActivePure® to expose Staphylococcus epidermis and MS2
bacteriophage to hydroxyl radicals and super ions formed as the result of UV exposure on the photo catalyst, has the ability to destroy the tested bio
organisms on the filter as shown in Table 1 below.
