The Tensui Water Perfection System is the only system to use a unique combination of essential elements to filter water the way nature does. Purely. Thoroughly. Perfectly.


Because Tensui will be installed at the point where water enters your home, every single drop of water will be treated.

Tensuiseki adjusts the water to a stable alkaline pH, increases dissolved oxygen content, and imparts trace minerals (such as calcium, potassium, magnesium, dissolved silica, among others) thereby raising Tensui Water’s electrolytic content.


Infra Red Pile_RGB_sm.jpg

Far Infrared
This proprietary ceramic medium, made from far infrared emitting stone, increases the far Infrared negative ions in the water. These ions enhance the antioxidant effect which helps the body in fighting immune disorders.


Pi Ceramic
Pi Ceramic is another material that releases far Infrared negative ions, which helps to further enhance the antioxidant effect of Tensui Water.

Gaia Pile_RGB_sm.jpg

Gaia Stone
This ancient Oriental stone has been used throughout the centuries in Japan to purify water. Gaia Stone detoxifies Tensui Water and reduces heavy metals by producing short-lived negative ions that create a bacterial-static and fungi-static quality to the water.


SPG Sand-Pile_RGB_sm.jpg

SPG Sand
Mined in the Orient, this rich volcanic sand has a surface area of 6.16 meters per gram and virtually no water flow restrictions. These qualities make it uniquely effective at removing suspended solids, particulates and heavy metals.


This semi-precious stone is rich in negative ions, which helps to structure the water and promote an alkaline content.


Tourmaline Ceramic
A piezo-electric quartz rich in negative ions, Tourmaline Ceramic increases the pH of the water. Tourmaline Ceramic also releases potassium, calcium, magnesium, iron and zinc into the water.


Magnetic Pile_RGB_sm.jpg

Magnetic Energy Ceramic
This patented arrangement of high gauss magnets changes the very structure of the water molecule, creating a micro cluster which conditions Tensui Water, giving it a soft, luxurious feel. It also helps to prevent minerals and metals from depositing on fixtures and pipes, while increasing water solubility.

Hydrogen pile_RGB_sm.jpg

Hydrogen Ceramic
Hydrogen Ceramic not only adds hydrogen but also calcium, potassium, magnesium and zinc to the water. This increases the ORP responsible for the antioxidant value and the micro clusters that make alkaline water more hydrating. Additionally, it helps neutralize the harmful effects of free radicals on the body.

Magnesium Pile_RGB_sm.jpg

Magnesium Crystals
These crystals add trace amounts of magnesium for pH adjustment and taste, while increasing ORP — oxidation reduction potential — which neutralizes free radicals.

Vitamin C Pile_RGB_sm.jpg

Calcium Ceramic
This mineral adds trace amounts of calcium to Tensui Water for pH adjustment and taste enhancement.

Quartz pile_RGB_sm.jpg

Quartz increases the piezo-electric quality of Tensui Water, while amplifying the water’s taste and its energy. 

Carbon Pile_RGB_sm.jpg

Tensui uses only the finest coconut shell carbon, Centaur carbon, bamboo carbon, bone char carbon and highly activated carbon. Together, they remove chlorine, chloramines, herbicides, pesticides, fluoride, VOC’s and MTBE’s from Tensui Water.

Coral Pile_RGB_sm.jpg

Coral Calcium
This mineral is rich in both calcium and magnesium, which enhances Tensui Water’s taste and while elevating its pH.


This copper zinc alloy is a bacterial-static medium that reduces chlorine and heavy metals, while also extending the life of Tensui carbon.
