The Stratus 2.0 Ozone Generator was designed by Simply O3 with the home-user in mind. Easy to use, economic, and brick sized, the Stratus 2.0 offers a long lifetime of 10,000 hours. The Stratus provides contaminant free ozone so it can be used for any application. Each machine is fitted with a custom chart of concentrations to ensure the accuracy of the concentrations. The machine is the size of a brick, can be picked up with one hand, and weighs under 3 pounds which makes it easy for storage and transport. Simply O3 designed this machine using cold corona discharge.
