Santevia Mineral Stones – Stage 7 Alkaline Remineralization for the Gravity Water System
After six stages of purification, your Gravity Water System water is clean — but stripped of the beneficial minerals your body needs. Santevia Mineral Stones complete the process: as the final (7th) stage of the Gravity Water System, they continuously infuse your filtered water with calcium, magnesium, phosphorus, potassium, and trace minerals, while maintaining an alkaline pH — recreating the mineral profile of fresh mountain spring water naturally and passively, with no electricity and no maintenance beyond a 2-year replacement cycle.
Made in Vancouver, British Columbia, Canada. HS Code: 842121.
What Mineral Stones Do — and Why It Matters
Standard water filtration removes contaminants. It also removes or reduces the dissolved minerals that give natural spring water its characteristic smooth taste and health benefits. Reverse osmosis, activated carbon, and ceramic filtration all produce cleaner water — but also flatter, less mineral-rich water that lacks the calcium and magnesium your body uses for bone density, muscle function, electrolyte balance, and cardiovascular health.
Santevia Mineral Stones address this directly. Placed in the lower reservoir of your Gravity Water System, they release minerals continuously as water contacts the stone surface — the same process that occurs naturally as water flows over mineral-rich rocks in mountain streams. The result is water that is both clean and actively mineral-rich.
Maifan Stones + Bio-Ceramic Energy Balls: How They Work
Maifan Stones
Maifan stone is a naturally occurring mineral-rich rock used in traditional East Asian water treatment for centuries. It contains a complex matrix of silica, calcium, magnesium, potassium, phosphorus, iron, and trace elements. When water contacts maifan stone, a slow ion-exchange process releases these minerals into solution — gradually and continuously over the stone’s 2-year service life. Maifan stone also has mild adsorptive properties that can help reduce residual organic compounds and improve water taste.
Bio-Ceramic Energy Balls
Bio-ceramic balls are manufactured from a blend of natural minerals fired at high temperature. They emit far-infrared radiation at wavelengths that interact with water molecules, reducing water cluster size and improving mineral absorption. They also contribute additional trace minerals to the water and help maintain alkaline pH by releasing alkaline mineral ions.
What Mineral Stones Add to Your Water
-
Calcium — supports bone density, muscle contraction, and nerve signaling; one of the most commonly deficient minerals in North American diets
-
Magnesium — essential for energy metabolism, electrolyte balance, cardiovascular health, and over 300 enzymatic reactions in the body
-
Phosphorus — supports bone and tooth structure, energy production (ATP), and cell membrane integrity
-
Potassium — regulates fluid balance, heart function, and blood pressure
-
Trace minerals — naturally occurring trace elements that contribute to overall mineral balance and improve water taste
-
Alkaline pH — mineral ion release naturally raises and maintains water pH after filtration, preventing the pH drop that occurs in purified water stored in the lower reservoir
The Mountain Spring Water Effect
Natural mountain spring water acquires its mineral content and alkaline pH by flowing slowly over and through mineral-rich rock formations over extended periods. Santevia Mineral Stones replicate this process in your Gravity Water System’s lower reservoir: filtered water sits in contact with maifan stones and bio-ceramic balls, gradually absorbing minerals and raising pH — producing water with a mineral profile and taste comparable to premium natural spring water, at a fraction of the cost and without the plastic bottle waste.

Replacement Schedule
Replace Santevia Mineral Stones every 2 years — the longest replacement interval of any Gravity Water System component. Unlike the filter cartridges (replaced every 4–6 months), mineral stones have a 2-year service life, making them a low-maintenance, high-value addition to your filtration setup. Over time, the stones’ mineral release rate gradually decreases as the surface becomes depleted — replacement at the 2-year mark ensures consistent mineral output and alkaline pH maintenance.
Perfect For
- Existing Santevia Gravity Water System owners completing or upgrading their filtration setup
- Health-conscious households wanting mineral-rich, alkaline drinking water
- Anyone replacing expired mineral stones after the 2-year service life
- Households reducing bottled mineral water consumption
- Those seeking the full 7-stage Gravity System filtration experience
Frequently Asked Questions
What do Santevia Mineral Stones add to water?
Santevia Mineral Stones release calcium, magnesium, phosphorus, potassium, and trace minerals into your filtered water through a natural ion-exchange process. They also maintain an alkaline pH by releasing alkaline mineral ions — preventing the pH drop that occurs in purified water stored in the lower reservoir.
How long do Santevia Mineral Stones last?
Up to 2 years — the longest replacement interval of any Gravity Water System component. Replace at the 2-year mark to maintain consistent mineral output and alkaline pH.
Are Santevia Mineral Stones compatible with all Gravity Water Systems?
Yes — Santevia Mineral Stones are designed for use with the Santevia Gravity Water System (countertop and dispenser models). They are not compatible with the Santevia MINA Pitcher or other Santevia product lines.
What are maifan stones?
Maifan stone is a naturally occurring mineral-rich rock used in traditional East Asian water treatment. It contains calcium, magnesium, potassium, phosphorus, iron, and trace elements, and releases these minerals slowly into water through ion exchange. It also has mild adsorptive properties that can improve water taste.
What are bio-ceramic energy balls?
Bio-ceramic balls are manufactured from a blend of natural minerals fired at high temperature. They emit far-infrared radiation that interacts with water molecules, contribute additional trace minerals, and help maintain alkaline pH by releasing alkaline mineral ions.
Do Mineral Stones filter contaminants?
No. Mineral Stones are a remineralization stage, not a filtration stage. They are designed to add minerals and maintain alkaline pH after the water has been purified by the Gravity System’s filter cartridge and ceramic pre-filter. For contaminant removal, the filter cartridge (5-Stage or Fluoride Filter) is the relevant component.
Why does purified water need remineralization?
Filtration removes contaminants — but also reduces or eliminates the dissolved minerals that give natural spring water its smooth taste and health benefits. Purified water without remineralization is flat-tasting and lacks the calcium and magnesium your body uses for bone density, muscle function, and electrolyte balance. Mineral Stones restore these minerals naturally, producing water comparable in mineral profile to premium natural spring water.
