Brand: Sigotan (HK) Industrial Co. Limited
SKU: S04-113 (Alka spring filter)
Price: 139.00 NZD
Availability: InStock

The Alka Spring cartridge transforms soft, acidic, or demineralized water into refreshing, mineral-rich drinking water. Engineered with four specialized stages, its primary purpose is to restore essential electrolytes, infuse beneficial minerals, and raise pH, while gently polishing the water to reduce residual chlorine and odors.

What this cartridge is designed to support

Optimal Hydration & Taste

Restores natural mineral balance and a silky-smooth mouthfeel, making it noticeably more refreshing and easier to drink your daily water.

Mineral Enrichment

Adds bioavailable magnesium, calcium, and essential trace minerals back into your water using natural Maifanite (Wisdom Stone).

Electrolyte & pH Balance

Naturally elevates water pH to an alkaline 8.0 to 9.5, helping counter the acidity common in Reverse Osmosis systems and rainwater plastic tank storage.

Molecular Hydrogen & Antioxidants

High-purity magnesium beads react with water to generate dissolved molecular hydrogen (H2) and negative ORP (-100 to -400 mV), providing natural antioxidant potential.

Everyday Vitality & Flavor

Combines natural mineral stones to eliminate the flat, hollow taste of stripped water, restoring the crisp taste of natural spring water.

Pure Taste & Odor Reduction

High-grade activated carbon captures residual chlorine, chloramines, volatile organic compounds (VOCs), and stale tank odors for clean, polished water at the tap.

These are general wellness associations, not medical claims. Alka Spring is a water mineraliser and conditioner, not a therapeutic or medical device.

How it works

Far-Infra-Red (FIR) Ceramic Beads

Natural mineral ceramic beads provide an engineered media bed that balances water flow and maximizes contact time, gently conditioning the water as it passes through.

Molecular Hydrogen & Alkaline Minerals
High-purity elemental magnesium beads naturally react with water to generate dissolved molecular hydrogen and raise pH to an alkaline 8.0 to 9.5. This process creates a negative ORP of -100 to -400 mV, enriching your water with bioavailable magnesium and natural antioxidant properties.

Essential Minerals & Trace Elements
Infuses water with trace minerals using natural Maifan stone (Wisdom Stone), slowly releasing calcium, potassium, and silica. This restores essential mineral balance and conditions mouthfeel, recreating the crisp taste of natural spring water.

Certification & testing

Minerals sourced and tested before use in drinking water applications, screened for heavy metals, toxins and microbial contaminants, and manufactured to EU RoHS standards

What this cartridge is designed to support

Rainwater (concrete tank)

Generally lacks minerals and is acidic unless stored in a concrete tank. Remineralization is not recommended for long-term rainwater storage without one.

Rainwater (plastic tank)

Plastic tanks remain acidic and lack minerals — this is exactly the scenario the Alka Spring is designed to correct.

Concrete tank storage

Concrete leaches some alkalizing minerals (Ca/Mg) into the water already, but the range and consistency are limited — a remineralizer is still recommended.

Reverse osmosis filtered water

RO strips out contaminants but also minerals, leaving water acidic (~pH 5.9). Remineralizing is strongly recommended before drinking.

Your water is mineralized. Now, amplify it.

The Alka Spring cartridge you're looking at handles the Mineralize phase - restoring bioavailable magnesium, calcium, and trace minerals while balancing pH.

The next step in your hydration journey is Activate: supercharging that mineral-rich water with high-concentration molecular hydrogen (H2), a potent natural antioxidant that supports everyday vitality, cellular hydration, and optimal recovery.

High-potency molecular hydrogen for enhanced antioxidant support
Supports daily energy, focus, and active recovery
Advanced electrolysis-no added chemicals, just pure water and electricity
Works seamlessly with your Alka Spring mineralized water

FAQ

Find the most frequently asked questions below.

The Alka Spring cartridge enhances water quality by naturally remineralizing, raising pH, and infusing dissolved molecular hydrogen. Designed primarily to restore demineralized, acidic, or soft water (such as after Reverse Osmosis or rainwater storage), it uses high-purity magnesium, natural Maifan stone, and ceramic conditioning to deliver crisp, balanced spring-quality drinking water.
The natural ceramic beads form an engineered conditioning bed that optimizes water flow distribution across the cartridge chambers. This ensures balanced contact time across all mineral stages, allowing the water to be gently conditioned and stabilized as it passes through.
The cartridge contains high-purity (99.5%) elemental magnesium beads that naturally react with water to generate dissolved molecular hydrogen (H2). Molecular hydrogen acts as a natural selective antioxidant and creates a negative Oxidation-Reduction Potential (-100 to -400 mV), while gently elevating pH to an alkaline 8.0 to 9.5.
The cartridge enriches water with essential dietary magnesium ions alongside natural trace minerals from Maifan stone (Wisdom Stone), including calcium, potassium, and silica. These minerals restore natural electrolyte balance, eliminate the flat taste of stripped water, and create a silky-smooth mouthfeel.
Cartridge lifespan depends on your household water usage and source water quality, typically lasting between 6 to 12 months. Regular replacement ensures consistent mineral release, optimal alkaline pH, and effective carbon taste polishing.

Particles in alkaline water

We love the alkaline water but this last filter had white mineral particles floating in the water for about 2 weeks. They’ve mostly gone now but most of the family won’t use the alkaline tap now

Happy Customer

Fantastic customer service and prompt delivery!
Have combined with FluorEx Max cartridge for an under sink set up - working well and tasting great.

All is well thank you

Prompt Service

The merchandise arrived in a timely manner. Thank you

Very good

Helped me with the order. Friendly, fast and efficient.

We value the quality

I can only say that I really value the quality of Ionza products, as well as Josef's knowledge and passion

Happily surprised

I don’t tend to drink much water, but since I use this product I am looking forward to drinking just water, as the taste is surprisingly delicious !

Water tastes great

High quality product and lovely helpful people

Great Product

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