Tersano's cartridge is a patent protected filtration system. Cold water enters the cartridge, where resins remove select contaminants. Once stabilized, this water is ready to be infused with ozone and creates SAO™. The SAO-24 cartridge will dispense 3,000 liters of SAO™ which last up to 24 hours as a sanitizer and 6 days cleaner.
