Since Tersano was founded, we have kept millions of liters of cleaning chemicals out of our lakes, rivers and waterways.
SAO has been certified safe by the top regulatory bodies around the world and is safe for use in the most sensitive environments. From governmental bodies to independent test laboratories and sustainability organizations, stabilized aqueous ozone is a safe, sustainable alternative to traditional chemical cleaners and sanitizers.
