EcoHero 5-Stage Reverse Osmosis Review: 12 Months Under My Sink in Palm Beach QLD

The EcoHero 5-Stage reverse osmosis system removes fluoride, lead, PFAS, and virtually every dissolved contaminant from your tap water — then adds minerals back via a remineraliser so the result is water that tastes genuinely good, not flat. It is the most comprehensively certified under-sink RO system stocked by an Australian supplier, and after 12 months of daily use at my home in Palm Beach QLD I would buy it again.

My Testing Setup — Palm Beach QLD

I tested the EcoHero 5-Stage over 12 months of daily use at my home in Palm Beach QLD — a suburb on the Gold Coast that receives chloramine-dosed Gold Coast Water supply. As a former Royal Australian Navy Clearance Diver, I have calibrated instruments and a precise approach to measurement. Nothing in this review is a manufacturer claim — every reading was taken by me, with a calibrated TDS/EC meter, from water drawn in my kitchen.

TDS — Total Dissolved Solids — measures dissolved ionic content in milligrams per litre. It does not identify specific contaminants, but it gives a fast, repeatable before/after signal for whether an RO membrane is performing. A properly functioning RO membrane should reduce TDS by 85–95% or more. The EcoHero-50 membrane is NSF 58 certified at 90.8% TDS reduction under controlled conditions. Real-world performance in my testing was 95.7%.

My testing methodology: both samples drawn from the same tap run within 2 minutes of each other. Meter calibrated to manufacturer spec before testing. Glass rinsed between tests. Three readings taken for each sample — the stable hold reading recorded. Water temperature: 30.0 degrees C for both.

The 5 Filtration Stages — What Each One Does

Reverse osmosis at 0.0001 microns removes virtually everything dissolved in water. The reason the EcoHero runs 5 stages rather than 3 is that the extra stages solve real problems: the deionising cartridge at stage 4 polishes out residual TDS that the RO membrane leaves behind, and the remineraliser at stage 5 solves the taste problem that makes pure RO water flat and unappealing. Each stage earns its place.

The EcoHero-50 membrane is Pure Water Systems’ proprietary membrane with a 50% water recovery rate. That means 1 litre of brine produced per 1 litre of filtered output. Older residential RO membranes typically waste 3–4 litres per litre filtered. The efficiency improvement is meaningful in states with water restrictions — South Australia, Western Australia, and parts of Queensland.

Real-World Performance — 69 ppm Down to 3 ppm

Palm Beach mains water from Gold Coast Water tested at 69 ppm TDS on the day of my measurement — well within the ADWG 2022 acceptable limit of 600 ppm, but still carrying fluoride, chloramine, and trace dissolved solids. Post-filter EcoHero output measured 3 ppm. That is a 95.7% TDS reduction — exceeding the NSF 58 certified spec of 90.8%.

Palm Beach supply sits at the low end of Australian mains TDS. Harder supplies — western Sydney, parts of Melbourne, outer Perth — regularly run above 200 ppm. At 69 ppm input and 3 ppm output, the EcoHero-50 membrane is operating well above its certified spec. Systems that perform at this level on easy water will maintain better-than-spec performance on harder Australian supplies.

Installation — What to Expect

The EcoHero 5-Stage requires a licensed plumber for installation. This is not optional under the product warranty or under Australian Standards. Budget $150–400 on top of the $1,009 system price depending on your location and whether your bench already has a pre-drilled hole. Pure Water Systems at 1300 808 966 can refer you to local installers who work with their systems regularly.

The install itself takes 1.5–2 hours. Everything is in the box. The plumber connects the cold water feed line under the sink, mounts the filter column and pressurised storage tank, drills the dedicated faucet hole in the bench (granite and stone benches require a diamond drill bit — confirm with your plumber), and runs the waste line to the drain. The dedicated RO faucet sits alongside your main mixer tap. Once installed, there is nothing to think about — filter change reminders come from the cartridge monitor built into the system.

The stone bench hole is the most common complication. If your kitchen has a granite or engineered stone benchtop, confirm before booking that the plumber has a diamond core drill. It takes 10 minutes with the right tool and risks cracking the bench without it. Budget an extra $50–100 for this if your plumber does not include it. Everything else about the install is standard under-sink plumbing — no unusual complications in 12 months and no leaks since installation.

12 Months of Daily Use

The unit has been in daily use since March 2026. No leaks, no failures, no filter alarms outside expected service intervals. Flow rate fills a standard 250mL glass in about 5 seconds and a full litre in 20–25 seconds. The 12–13 litre pressurised tank handles normal household demand without noticeable draw-down — two people drinking 2–3 litres per day each puts no real load on the tank. Under heavy use (cooking a large meal, filling a water pitcher repeatedly) the tank does require time to refill, but this has never been an issue in day-to-day use.

The remineraliser is the feature that makes this system worth using every day. Pure RO water — post-membrane, pre-remineraliser — is flat, slightly acidic, and genuinely unpleasant. The remineraliser adds calcium, magnesium, and potassium back into the water and raises the pH. The output tastes clean and subtly mineral — noticeably better than unfiltered tap water and noticeably different from plain RO without remineralisation. Coffee and tea made with remineralised RO water taste cleaner than with chloramine-dosed mains — the chloramine interference with aromatic compounds is eliminated.

Cartridge service: Pure Water Systems arranges the technician. You call them, they book a local plumber who arrives with all the cartridges and completes the replacement in under an hour. My first full service — all cartridges including the RO membrane — cost $490 all-in including labour. That is the realistic annual maintenance figure. Broken down, it is $40.83 per month — compared to the average Australian bottled water habit of $60–80 per month at supermarket prices.

How the EcoHero 5-Stage Compares

The under-sink RO category in Australia divides cleanly into three tiers: certified Australian-stocked systems with local support (EcoHero), imported tankless systems with local availability (Waterdrop D6), and countertop RO units for renters or those who cannot modify plumbing (AquaTru). Here is how the key specs compare.

The Waterdrop D6 is the main competition. It is tankless (instant flow, no pressurised tank), DIY-installable, and costs roughly $650–750 all-in — about $500–1,000 less than the EcoHero depending on plumber costs. It does not carry WaterMark certification, which matters for some Australian councils and landlords, and it lacks the Australian local phone support that Pure Water Systems provides. For homeowners who want the most comprehensively certified option with local service, the EcoHero is the call. For those who want to self-install and save on upfront cost, the Waterdrop D6 is a legitimate alternative.

Cartridge Costs and 5-Year Ownership

The system price is the beginning of the cost story, not the end. Every RO system requires ongoing filter and membrane replacements. For the EcoHero 5-Stage, Pure Water Systems’ recommended schedule is: sediment and carbon cartridges every 6 months, RO membrane every 24 months, deionising and remineraliser cartridges every 6–12 months depending on water quality.

The 5-year ownership cost of the EcoHero is approximately equal to the cost of buying 2 litres of bottled water per day at supermarket prices ($1/L). After 5 years, the EcoHero household pays nothing — the bottled water household keeps paying $730 per year forever. According to ABS waste data, the average Australian household using bottled water generates approximately 600 plastic bottles for landfill each year. The EcoHero eliminates that entirely.

The $490 annual service figure from my own service is the key number to budget for. Pure Water Systems arranges the technician — you do not source parts or find a plumber yourself. That managed service is worth factoring into the comparison: the alternative is sourcing cartridges independently and finding a plumber, which may cost less per cartridge but adds your time and coordination overhead.

Final Verdict

Twelve months of daily use, zero failures, water that tastes genuinely good, and every contaminant I care about gone. The EcoHero 5-Stage earns its WaterMark and NSF 58 credentials — real-world performance at 95.7% TDS reduction exceeded the certified spec. The remineraliser is what makes it liveable: pure RO water is flat and unpleasant; remineralised RO water is what good water should taste like.

The honest limitations: you need to own your home, budget $1,200–1,700 all-in, and be willing to commit to $490/year in service. That is not a trivial spend. For renters, the AquaTru Classic countertop RO is the correct answer — no plumbing, five NSF certifications, and a fraction of the install cost. For homeowners who want the most comprehensively certified, locally supported under-sink RO available in Australia, the EcoHero 5-Stage is the benchmark.

Frequently Asked Questions

Does the EcoHero 5-Stage remove fluoride?

Yes — 93.6% fluoride removal via the NSF 58 certified EcoHero-50 membrane. After the deionising cartridge at stage 4, TDS drops to near-zero ppm, which means fluoride concentration is effectively zero at the tap. This is independently verified, not a manufacturer claim.

Do I need a plumber to install the EcoHero 5-Stage?

Yes. Installation requires a licensed plumber — it is a condition of the product warranty and consistent with Australian Standards for under-sink plumbing modifications. Budget $150–400 for labour depending on location. Pure Water Systems at 1300 808 966 can refer you to local installers who are familiar with the system.

Can renters install the EcoHero 5-Stage?

No. The system requires a permanent bench hole for the dedicated faucet and permanent under-sink plumbing connections. Both require property owner consent and are not practical for renters. The AquaTru Classic countertop RO requires no plumbing and is the correct alternative for renters.

Does the EcoHero 5-Stage remove PFAS?

Yes. Reverse osmosis at 0.0001 microns is one of the most effective residential methods for PFAS reduction. The EcoHero-50 membrane is rated for PFAS removal. For independent confirmation, check the NSF 58 certification documentation available from Pure Water Systems.

What is the EcoHero-50 membrane and why does it matter?

The EcoHero-50 is Pure Water Systems’ proprietary RO membrane with a 50% water recovery rate. That means 1 litre of brine produced per 1 litre of filtered output. Standard residential RO membranes waste 3–4 litres per litre filtered. In states with water restrictions — South Australia, Western Australia, parts of Queensland — the efficiency difference is meaningful.

How much does EcoHero 5-Stage servicing cost?

Based on my own first full service in 2026: $490 all-in including all cartridges and labour. Pure Water Systems arranges the technician — you call them, they book a local plumber, the plumber arrives with all parts and completes the service in under an hour. No sourcing cartridges yourself, no finding a plumber independently.

Is the EcoHero 5-Stage WaterMark certified?

Yes — WaterMark certification to AS3497. This is the Australian standard for plumbing products that contact drinking water. It confirms the system materials and construction meet Australian regulatory requirements. Not all imported RO systems sold in Australia carry this certification.
