Ionplus Underbench Ionizer

Based on your selected preferences:

  • Under-bench system
  • Built-in water activation
  • Targeted / comprehensive filtration options

We’ve recommended the Ionplus Underbench Ionizer System as the best fit for your home and hydration goals.

Designed for those wanting freshly ionised alkaline water from a clean, built-in under-bench setup, this system combines the IonPlus 7-Plate Ioniser with multi-stage internal filtration and optional targeted filter upgrades to support cleaner, mineral-retaining, ionised water directly from your kitchen tap.

  • Remove — The built-in IonPlus filtration system helps reduce common drinking water concerns such as sediment, particles, rust, chlorine, taste, odour, fine contaminants, bacteria, and heavy metals. Optional targeted filtration can also be selected for specific contaminants such as fluoride, nitrates, microplastics, or enhanced bacterial protection.
  • Restore — The IonPlus retains more of the water’s natural mineral profile than reverse osmosis systems. An optional mineral enhancement cartridge can also be added to further support mineral balance, improve taste, and create a smoother drinking experience.
  • Activate — Through electrolysis, the IonPlus produces freshly ionised alkaline water on demand, with adjustable pH settings for everyday use. Small amounts of dissolved hydrogen are also naturally created as a byproduct of the ionisation process.
What does this system remove?

The Ionza Ionised Underbench System includes advanced internal multi-stage filtration designed to improve water quality before ionisation occurs. The built-in filtration helps reduce many of the common contaminants found in household water supplies while supporting better taste and electrolysis performance.

Built-in filtration helps reduce:

→ Chlorine, taste & odour
→ Sediment, particles & rust
→ Fine contaminants & impurities
→ Heavy metals
→ Some bacteria through anti-bacterial ceramic media

The system is designed to refine your existing water while producing freshly ionized alkaline water directly from the tap.

What this system does not cover

While the built-in IonPlus filtration covers many common water concerns, some water supplies may require additional targeted filtration depending on your location, infrastructure, or water quality goals.

Optional upgrade filters are available for:

→ Fluoride reduction (FluorEx Max)
→ Nitrate reduction for rural/agricultural areas (NIT10)
→ Enhanced bacteria & microplastic protection (Ultra Filter)
→ Extended chlorine, chemical & sediment reduction (Active Pure Xtra)

These upgrades can be added to customise the system around your specific water source and preferences.

→ Consider PureRevive

Where this system fits

This system is ideal if:

  • You have treated town water or relatively clean source water
  • You want ionized water without a complex setup
  • You prefer an all-in-one underbench solution
  • You want adjustable pH and ORP levels
  • Complete system for highest level of filtration (REMOVE + RESTORE + ACTIVATE)

It’s a great option for those wanting to upgrade their water experience without installing multiple systems.

HERE'S THE PROBLEM

Filtered water is clean. Ionized water is alive.

Standard filtration removes contaminants but leaves water chemically unchanged — same pH, no antioxidant activity, no dissolved hydrogen. Ionization goes further: using electrolysis, the IonPlus transforms filtered water into alkaline, hydrogen-rich, antioxidant-active water with a wide pH range for drinking, cooking, cleaning and skincare.

Benchtop ionizers do the job but sit on your counter and clutter your workspace. The Underbench system keeps everything hidden — delivering the same ionized output through a sleek dedicated tap.

Tap Water Has Positive ORP

Most treated tap water carries a positive oxidation-reduction potential — the opposite of what antioxidant-rich water provides.

Benchtop Ionizers Take Space

Countertop ionizers are bulky, use diverter valves, and clutter your bench. Underbench keeps everything hidden away.

One pH Doesn't Do Everything

Drinking, cooking, cleaning, skincare — each works best at a different pH. The IonPlus gives you a full range from 3.0 to 10.5.

Wellness Starts With Water

Alkaline ionized water supports metabolism, hydration, and detoxification in ways ordinary filtered water simply doesn't
HOW IT WORKS

Remove. Restore. Activate.

Three deliberate stages designed to transform your water quality.
1
REMOVE

Multi-Stage Internal Filtration

Water passes through a multi-layer cartridge that captures particles, chemicals, and biological contaminants — producing clean water ready for mineralization and ionization.
  • Sediment filtration — rust, silt, particulates
  • Activated carbon (coconut shell) — chlorine, chemicals, odours
  • Carbon Block — KDF-style heavy metal reduction
  • Advanced ceramic & mineral media — additional support
  • Antibacterial ceramic — inhibits bacterial growth
2
RESTORE

Mineral Balance (Optional)

Before ionization, the internal filter media adds back essential minerals — calcium, magnesium and trace elements — to stabilize the water and ensure the ionizer performs consistently.
  • Adds calcium, magnesium & trace minerals
  • Supports a balanced, natural mineral profile
  • Improves taste and mouthfeel
  • Stabilises water for effective ionisation
3
ACTIVATE

Electrolysis Ionization System

Filtered, mineralized water flows over 7 platinum-coated titanium plates under a precise electrical charge — producing alkaline ionized drinking water with negative ORP and dissolved hydrogen.
  • pH range: 3.0 (acid) to 10.5 (strong alkaline)
  • ORP: down to −800 mV — antioxidant active
  • Dissolved molecular hydrogen: up to 1300 ppb
  • MICOM smart controls — auto-adjusts to source water
  • Automatic self-cleaning system

FAQ

Common questions, honest answers

  • It includes filtration, but is best suited to moderate contamination — not complex water issues. It's ideal for town water or relatively clean source water. For fluoride, nitrates, or unknown water quality, add an upstream pre-filter or pair with a whole house filter system.

  • No — the system does not include fluoride-specific filtration. However, the FluorEx pre-filter add-on can be added upstream. Most NZ town supplies contain fluoride, so this add-on is commonly recommended for town water users.

  • Yes — the built‑in internal filter cartridge includes calcium, which is added before ionization to help stabilize the water and support effective ionization output.

    For those who want a broader mineral profile, you can add the Alka Spring mineral cartridge, which enhances the water with additional essential minerals beyond calcium, creating a more balanced and natural composition.

  • Yes — ionization is an electrolytic process that requires electricity. The unit installs underbench and connects to both a water line and a power outlet. Professional installation is recommended to ensure optimal performance.

  • Yes — and it's one of the most effective configurations. A LifeSpring Whole House Filter installed upstream protects every tap, shower, and appliance in your home, reduces the filtration load on the IonPlus internal cartridge, and significantly extends its service life.



  • The IonPlus is an all-in-one system — filtration, mineralization, and ionization in a single unit — best for those who want ionized water with minimal setup. PureRevive is a modular RO-based system offering maximum contaminant removal including PFAS and nitrates, better suited to unknown or more complex water quality.
