This item was included as a bonus when I purchased a cado dehumidifier, but I don't need it, so I'm selling it. High-Function Electrolyzed Acidic Ion Water "Purio" Purio is a high-function electrolyzed acidic ion water developed exclusively for cado humidifiers for the purpose of space disinfection. It was created through a collaboration with One-Tens' unique electrolysis technology (patented technology). Capacity: 120mL
