Case Studies

Ball State University

"Housing and Residence Life introduced the cleaning agent in 2014 and now uses it in all 10 residence halls to wash and sanitize floors, windows, restrooms, computer labs and common spaces. It’s good for the environment, safe and healthy for employees and has cut annual spending on chemical cleaning products by more than $100,000."


University of Wisconsin-Madison

"We'll never go back to harsh chemicals. Everyone here has embraced it. Today, staff and students naturally demand sustainability and alternative ways of doing things. With the Stabilized Aqueous Ozone system, we're saving money, we're greener, and my staff is healthier. Why would I ever use harsh chemicals again?"
