A nanoe™X is a fine (5 to 20nm) and weak acidic water particle with a reactive substance and an electric charge. A nanoe™X device releases radicals in water molecules which effectively removes viruses, bacteria, odors and allergens. The effectiveness of virus and bacteria removal depends on the number of OH radical. The more OH radical, the higher effectiveness of the anti-virus power. A nanoe™X device generates at a high rate of 4.8 trillion per second.
