In 2001, tersano was established on the mission of Changing The Way The World Cleans by providing environmentally safe and sustainable alternatives to traditional chemicals.

We are committed to making schools healthier, cleaner, and safer by replacing harmful chemicals with sustainable cleaning technologies.

Simple • Safe • Sustainable

Our technologies transform tap water into Stabilized Aqueous Ozone (SAO®), nature’s most powerful cleaner, sanitizer, and deodorizer.

As an all-in-one solution, SAO replaces up to 90% of traditional cleaning products, providing carbon reductions, cost savings, and a safer campus for students and staff.
