These units do not use any chemicals, operate unattended and need only occasional cleaning and maintenance. They contain electrical and electronic components to generate ozone, using only small amounts of electricity. Sonozaire units are built of heavy-duty aluminum construction. Industrial ozone generators are designed to be used in uninhabited areas, or used at volumes that are limited by OSHA or EPA regulations. 

All models, except the 5G, allow users to adjust the ozone output according to the level of odor and the desired duration of treatment. The model 5G has an adjustable timer with continuous maximum output.
