The Santevia Alkaline Gravity Water System restores your tap water to a clean, great-tasting, mineralized and alkalized state, using the power of gravity alone – no chemicals, artificial materials, water pressure or electricity!
Every drop drips through a system of natural filters which clean and infuse your water with earth-derived minerals. The result is great-tasting water which helps you to keeps you stay healthy and hydrated.
 
Gravity System Filtration
The Gravity Water System employs a unique 8-Stage Filtration System which simulates the earth's own natural water purification systems. 
Stage 1: Ceramic Pre-Filter
Constructed from highly compressed and fired diatomaceous earth with a pore size of 0.3 of a micron, this pre-filter removes rust, sediments, bacteria, germs and parasites.
Stage 2: Granular Activated Coconut Carbon
This filter utilizes porous coconut carbon charcoal for an astounding 65 acres of purifying surface area. It filters chlorine, herbicides, pesticides, pharmaceuticals, industrial chemicals, trihalomethanes (THMs), heavy metals, organic chemicals, odour, taste, colour and particulates. This stage also contains a KDF filter medium that inhibits the growth of bacteria in the filter and neutralizes heavy metals. Magnesium granules reduce harmful Oxidation Reduction Potential (ORP).
Stage 3: Silica Sand
This stage inhibits bacteria and neutralizes heavy metals such as lead, nickel, cadmium and mercury through an ion exchange process. It filters detergents, ammonium, agricultural chemicals as well as some types of radioactive ions and toxins.
Stage 4: Mineral Stone Infusion
In this stage, porous Maifan mineral stones infuse ionized minerals into the water, promoting oxygenation and alkalization.
Stage 5: pH Mineral Balls
Mineral ions encased in diatomaceous earth add calcium, magnesium and other trace minerals to fortify the water and increase the pH.
Stage 6: Energy Balls
Energy Balls, constructed by mixing earth and mineral oxides before comprising and firing them, assist with pH balancing and emit beneficial infrared energy into the water.
Stage 7: Mineral Stone Immersion
During this stage, mineral stones continuously release easily absorbed, ionized minerals into the water, including calcium, iron, magnesium, potassium, zinc and other trace minerals.
Stage 8: Magnetic Energy Tap (Countertop Model Only)
Embedded in the Santevia water spout, aligned magnets are suspended
