The ALKA SPRING is an incredible antioxidant composite cartridge that will revolutionize your water experience:

  • It harnesses the power of Far-Infra-Red (FIR) Energy Beads and Mineral balls to ionize and enhance your tap water.
  • Improving energy levels; Prepare to be amazed as it introduces antioxidants with a negative Oxidation-Reduction Potential (ORP) into your tap water, promoting health and vitality.
  • Get ready for a pH boost! The ALKA SPRING raises the pH of your tap water to approximately pH 8.5-9.5, creating a refreshing and alkaline drinking experience.
  • Say goodbye to ordinary water molecules. This filter transforms tap water into smaller clustered molecules, enhancing hydration and absorption by your body.
  • Restoring alkaline buffers, eliminating body acidity and reducing free radicals
  • Increasing antioxidants
  • Increasing oxygen-uptake
Key Features

Far-Infra-Red Energy Beads: These beads are made from natural infrared raw materials with maifanshi stone and seabed minerals that contain useful trace elements. Using advanced ceramic technology, In the Far-Infra-Red process, the organisms absorb frequencies of 8-14um, which has 90%+ infrared emissivity. The released infrared energy can be easily absorbed, producing smaller water molecule clusters.

Negative Ion Minerals: The ALKA SPRING is a powerhouse of negative ions. By infusing ionic minerals into the source water, it adds negatively charged ions, further enhancing the water's beneficial properties.

Essential Minerals and Trace Elements: Prepare to be nourished! The ALKA SPRING enriches your water with a variety of essential minerals and trace elements. Up to 90 rare trace minerals including Strontium, lithium, silicon, zinc, selenium, calcium, potassium, work together to support the healthy functioning of your body. This Cartridge contains Maifenite (Wisdom stone) renowned for its health benefits in China, Japan and other parts of Asia and known as the Health Stone. Maifenite is a compound mineral with a wide range of minerals and trace elements. It is produced in the valley streams of porphyritic pea gravel, called Maifanshi in Ancient China. Maifanite is weathered granite, diorite comprised of plagioclase, black mica, quartz, hornblende, chlorite and more. Its packed with minerals. Japanese call it "longevity stone" while Koreans called it "medicine stone." Chinese have used it for many centuries to maintain good health. In China it is called ‘wisdom stone’. It has been used to mineralise drinking water, and also for bathing. Maifanite contains a wide range of minerals. Its chemical composition shows that it also contains rare earth elements. Maifenite or Maifanshi is non-toxic, harmless and has a certain biological activity of compound mineral or medicinal rocks.  Its main chemical components are inorganic aluminosilicate. These include Sl2O3, Fe2O3, FeO, MgO, CaO, k2O, Na2O, TiO2, p2O5, MnO, etc., but also contains all the necessary constant elements which are  needed by humans and animals, such as: K, Na, Ca, Mg, Cu, Mo and many other trace elements.

Product Specifications

Water Sources:

Rainwater Source: Generally lacks minerals and is acidic unless stored in a concrete tank. Rainwater as a regular drinking source leaches the body of minerals. As a result, drinking rainwater long term without remineralization is not recommended.

Plastic tank Storage: Rainwater stored in plastic tanks remains acidic and lacks minerals.

Concrete tank Storage: In a lot of cases the concrete walls of the tank offer the rainwater alkalizing minerals, lifting the ph into alkaline, and providing Ca and Mg minerals for the ionization. A remineraliser would not be needed for most of the time, however the range of minerals is very limited to a few minerals: Calcium and Magnesium. It is recommended to install a remineralizer also for a concrete tank

Reverse Osmosis Filtered water: is stripped of contaminants, which is a good thing, however it is also stripped of minerals, which is an unfortunate outcome. Further the reverse osmosis water is acidic at a pH of approx 5.9. To ionise reverse osmosis water, we need to demineralize it first. 

Electrolytic Ionisers: Introduction of minerals is necessary for ionization to work effectively. It is particularly relevant for being able to create higher pH 9.5 - 10. In that process ionisation is also offering a better presence of antioxidants.

Capacity: 3000 liters, depending on usage and water source: 10-15 months for a 2-3 person household.

Hygienic Life: Maximum 2 years.

Working Pressure: 15 - 65 PSI (Please note: a pressure reducing valve is required for water pressures higher than 70 PSI).

Working Temperature: 5-40˚C


H: 35cm x 7cm diameter.


If this is the first time installing this you may require a FILTER ATTACHEMENT KIT and/or a FILTER TAP. (Note: We have a range of Filter taps to choose from)

The Alka Spring cartridge is placed after an existing filter and before the filter tap.

Great Product

I had this system fitted and have never looked back. The system I have is really simple but makes a big difference.
