EnvironClean's Activated Oxygen Treatment eliminates allergens, odors, mold, pests, bacteria and viruses from air and surfaces. It is 3,000 times faster and 10 times stronger than chlorine, and scientists at the Los Alamos National Laboratory found that Activated Oxygen Shock Treatment is the only way to sterilize inaccessible areas in a space. Activated Oxygen has also been approved by the E.P.A. for food and drink purification. Activated Oxygen is a chemical free treatment, which is safe and will not damage the surfaces or contents of your space. Within minutes of completion, fresh air returns to a purified environment.
