IVO is made by Toray Industries, Japan. Toray is the largest producer of advanced carbon fiber technology.

IVO Faucet Mounted Water Purifier is a compact water filtration system that uses advanced hollow fiber membrane technology. This is the same technology used in dialyzers in dialysis machines, and artificial kidneys. From the makers of Torayvino, the no. 1 faucet mounted water purifier in Japan, IVO guarantees 99.99% bacteria-free drinking water. Ample water pressure is needed for water filter to work properly. For first time use—as a break-in procedure, please let water SLOWLY pass through the filter cartridge for 30 seconds (max) to prevent air bubbles, which may give you a premature slow water flow.
