Patented Technology.
Proven Science.
The lotus PRO creates SAO on demand by safely infusing tap water with ozone that has been stabilized to extend usability. SAO acts as a powerful oxidizer that breaks down soils and inactivates microorganisms*, then reverts to water and oxygen without leaving chemical residues.
The system connects to cold tap water.
The cold tap water enters the cartridge, removing select minerals to maximize ozone's longevity.
The lotus PRO V9 dispenser safely infuses the water with ozone.
A simple on/off switch controls the flow of SAO.
A series of indicator lights communicate the system's status in real time.
The desiccant filter removes moisture from the air and tracks the cartridge's cycles.
The lotus PRO V9 plugs into a standard electrical outlet.
The ready-to-use SAO solution dispenses into spray bottles, mop buckets, and floor scrubbers from the yellow nozzle.

Your Impact Potential

From Stanford University to McDonald's, our community of changemakers are sharing their stories on how SAO revolutionized how they clean, work, and operate business.
HSBC
"SAO reaffirms we have used a product that performs better than chemicals in every aspect of the value chain. EFS will deploy tersano SAO for the whole tower."
McDonald's
"We have made the installation and use of tersano SAO mandatory in our new McDonald’s restaurant openings and are very happy to encourage its use."
Stanford University
"It’s almost not even worth calling it green cleaning because it’s so much better. It is just as effective at killing viruses and bacteria as traditional chemical-based cleaners."
AdventHealth
"We simply have fewer chemicals to manage. We even use it on our floors. In the past, we would just be able to clean them. Now we can clean and sanitize them simultaneously."
Accor Hotels
"The benefits of SAO are many, but if I had to sum it up I would say it’s environmentally-friendly, safer for my staff, and very easy to use."
Toronto Pearson Airport
"We were receiving complaints regularly of strong odors in restrooms. Since our introduction of SAO, complaints about odors at the airport have been extremely reduced.”
F45 Fitness
"SAO is such an easy and affordable way to keep our gym clean. We would never go back to using cleaning chemicals. In fact, whenever I see Lysol wipes, my first response is YUCK!"
Shell Tower
“Using tersano to clean without chemicals is a dream come true. We’re saving over £25,000 a year in reduced chemical usage and labor hours.”
Woodley Acres Pet Resort
"We believe in providing a happy, healthy, and safe place for all our pets. With SAO, we fulfill that mission by removing toxic cleaning chemicals from our facility."
Domino's
"We make hundreds of pizzas a day. Bringing SAO in means we are keeping the cleaning chemicals out: out of our restaurant, out of our ingredients, and out of my staff’s hands."
