The SAO cartridge system is a resin based filter that cleans and removes contaminants found in tap water. It's a necessary item required for the Tersano SAO dispenser to work as effectively as possible. Each cartridge comes complete with indicators to identify when cartridge is no longer effective.
The SAO-24 can dispense up to 3000 litres of water before replacement is required. It also provides up to 24 hours of sanitising and 6 days of cleaning power.
