Key Features

Advanced 5 Stage Reverse Osmosis Purification with Remineralisation

The EcoHero 5 Stage Reverse Osmosis System with Remineraliser combines advanced multi-stage water purification, certified contaminant reduction and mineral-enriched drinking water.

Its ultra-fine 0.0001-micron reverse osmosis membrane reduces fluoride, heavy metals, dissolved salts and other unwanted contaminants. The additional filtration stage provides further water treatment, while the dedicated remineraliser cartridge reintroduces minerals and helps adjust pH after purification.

For customers selecting the PHN/Deioniser variant, the system includes the selected additional treatment option. The pH Neutraliser (PHN) helps adjust water pH, while deionisation (DI) further reduces residual dissolved ions. These treatments serve different purposes, and the included cartridge depends on the variant selected.

Designed for convenient under-sink installation, EcoHero provides purified drinking water for everyday use, including drinking, cooking, tea, coffee and food preparation.

Notes

Important Product Information

Installation, Pricing & Warranty: Professional installation by a suitably licensed plumber is required for the EcoHero 5 Stage Reverse Osmosis System and any accompanying faucet, in accordance with Australian plumbing regulations and our 12-month warranty conditions. Pure Water Systems can assist with arranging installation in serviceable areas. Online prices are for product supply only unless otherwise stated. Your rights under Australian Consumer Law remain unaffected.

Water Efficiency & Certified Performance: EcoHero reverse osmosis technology can achieve up to 50% water recovery, equivalent to approximately one litre of purified water for every litre of wastewater under optimal conditions. The EcoHero system has been tested and certified under AS/NZS 3497 for the reduction of 11 substances, including fluoride, lead and dissolved solids. Actual performance varies depending on incoming water quality, pressure, usage and filter condition.

Filter Maintenance & Remineralisation: Filter replacement intervals depend on household usage and incoming water quality. The remineraliser cartridge should be replaced approximately every 12 months, or sooner if performance declines. Remineralisation reintroduces minerals and helps adjust pH following purification, which may increase final total dissolved solids (TDS) readings compared with water measured directly after the RO membrane.

Remineraliser Laboratory Testing: Biocera conducted testing in August 2025 using a reverse osmosis system fitted with a remineraliser, assessing pH, oxidation-reduction potential (ORP), total dissolved solids (TDS) and dissolved hydrogen. Results reflect the specified laboratory conditions and may vary in household installations.

Certifications & Product Information: WaterMark certification applies to the specified EcoHero filtration system. Any accompanying faucet must meet applicable certification requirements separately. Specifications, pricing and compliance information may change without notice. Refer to current Pure Water Systems documentation for the latest product information.

WHAT IS REVERSE OSMOSIS?

Reverse osmosis is one of the most advanced methods of water purification, going beyond standard carbon filtration to reduce a wide range of contaminants found in drinking water.

The process forces water through an ultra-fine membrane, reducing dissolved impurities, including total dissolved solids (TDS).

The EcoHero system features the advanced EcoHero-50 Reverse Osmosis Membrane, designed to provide up to 300% improved wastewater efficiency compared with other reverse osmosis membranes.

Its ultra-fine 0.0001 micron membrane reduces total dissolved solids and contaminants such as fluoride, bacteria, viruses, herbicides, pesticides, nitrates and other organic and inorganic compounds.

The result is purified, great-tasting drinking water, conveniently available from your chosen faucet.

WHAT IS THE DIFFERENCE BETWEEN 4 AND 5 STAGE REVERSE OSMOSIS SYSTEMS?

The EcoHero 5 Stage Reverse Osmosis System includes an additional Deionising Cartridge, providing an extra level of purification beyond the 4 Stage system.

This additional cartridge helps remove residual total dissolved solids (TDS) remaining after reverse osmosis, achieving water purity levels similar to distilled water and as low as 0 ppm TDS under specified testing conditions.*

The deionising cartridge contains tiny resin beads that attract and capture electrically charged dissolved substances through a process called ion exchange.

This additional purification stage makes the EcoHero 5 Stage system ideal for customers seeking maximum contaminant reduction before remineralisation.

5 STAGE REVERSE OSMOSIS WITH REMINERALISER

The EcoHero 5 Stage Reverse Osmosis System with Remineraliser incorporates the following filtration components:

  • 1 Micron Pre-Filter

  • 10 Micron Carbon Block

  • EcoHero-50 Reverse Osmosis Membrane

  • Deionising Cartridge

  • Remineraliser Cartridge

  • Post Carbon Cartridge

Each component plays an important role in reducing contaminants, improving taste and restoring minerals to your purified drinking water.

WHAT IS REMINERALISED WATER?

Reverse osmosis is highly effective at reducing contaminants, including heavy metals such as cadmium, arsenic and chromium. However, the purification process can also remove naturally occurring minerals from water.

As part of the EcoHero 5 Stage Reverse Osmosis System, the Remineraliser cartridge is designed to reintroduce beneficial minerals after the purification process.

Why Choose a Remineraliser?

The EcoHero Remineraliser contains patented mineral crystal balls that help restore minerals to purified water, including calcium, magnesium, potassium and sodium.

The cartridge also raises the water's pH towards alkaline levels and is designed to reduce Oxidation Reduction Potential (ORP) while producing hydrogen-rich drinking water.

Installed inline with your reverse osmosis system, the remineraliser treats purified water during the final stage of the process.

What Is Oxidation Reduction Potential (ORP)?

Oxidation Reduction Potential (ORP) measures a substance's tendency to gain or lose electrons.

The EcoHero Remineraliser is designed to reduce ORP and produce hydrogen-rich drinking water as part of its remineralisation process.

Important Performance Information

Water recovery rates of up to 50% are based on optimal operating conditions. Actual water efficiency, filtration performance and flow rates depend on incoming water quality, water pressure, temperature and system maintenance.

Replacement filters should generally be changed every 12 months or 8,000 litres, whichever occurs first, unless individual cartridge instructions specify otherwise. More frequent replacement may be necessary depending on water quality and usage.

The remineralisation cartridge reintroduces minerals and helps adjust pH following reverse osmosis purification. As a result, final drinking water TDS readings may be higher than measurements taken immediately after the RO membrane.
