About The System
Bottled-Water Purity From Your Kitchen Tap
Sydney's mains water is treated and safe by regulatory standards — but it arrives at your tap containing chloramine, fluoride, trace heavy metals, and in some areas nitrates and PFAS. For households that cook, brew coffee, and drink directly from the tap every day, reverse osmosis is the most comprehensive solution available for residential use.
The Pure Plus+ uses a 75 GPD high-efficiency RO membrane to reject up to 99% of dissolved solids at the molecular level — including fluoride (up to 95%), chloramine, lead, copper, arsenic, nitrates, PFAS and microplastics. What passes through the membrane is near-pure water. Stages 1 and 2 pre-treat the feed water to protect the membrane. Stage 4 post-polishes taste. Stage 5 — the alkaline remineralisation cartridge — adds calcium, magnesium and potassium back, raising the pH to 7.5–8.5 for a clean, naturally balanced flavour.
The 12-litre storage tank ensures water is always available on demand — no waiting for filtration to complete before you can fill a glass. The dedicated chrome filter tap is installed through your benchtop, and a 3-way mixer tap upgrade is available if you'd prefer one fixture over two.
Jean-Paul installs every Pure Plus+ system personally across Sydney. He's a licensed NSW plumber (Lic. 461511C), not a subcontractor — every installation is done by the same person who answers the phone. Fixed price of $840 covers system, tank, chrome filter tap, all fittings, and licensed installation. No hidden extras.
Filter Stage Breakdown
Five stages work in sequence to deliver near-pure, alkaline remineralised water. Each stage has a specific role — from protecting the membrane to polishing the final output.
1
5-Micron Polyspun Sediment Filter
Pre-filter — Sediment, Particles, Silt
The first stage is a 5-micron polyspun sediment cartridge that removes physical particles from the feed water — sand, silt, rust, and suspended solids. Its primary job is to protect the RO membrane from clogging, extending membrane life and maintaining flow performance. This cartridge is replaced every 6 months in Sydney's mains water conditions.

CTO Carbon Block Pre-Filter
Pre-filter — Chlorine, Chloramine, Taste & Odour
The CTO (Chlorine, Taste, Odour) carbon block pre-filter removes free chlorine and chloramine before the water contacts the RO membrane — chlorine is particularly damaging to thin-film composite membranes. This stage also removes VOCs, herbicides, pesticides, and chemical taste and odour compounds. Replaced every 6–12 months.

75 GPD RO Membrane
Primary filter — 0.0001 micron, 99% TDS rejection
The heart of the system. The thin-film composite reverse osmosis membrane operates at 0.0001 microns — fine enough to reject virtually all dissolved contaminants including fluoride (up to 95%), lead, copper, arsenic, nitrates, PFAS, bacteria and cysts. Water molecules pass through; dissolved solids are flushed to drain. The membrane is typically replaced every 2–3 years.

Post Carbon Polish Filter
Post-filter — Final taste polish
After the RO membrane, this inline carbon post-filter removes any residual taste or odour compounds that may have developed in the storage tank. It acts as a final quality gate, ensuring every glass drawn from the tap tastes crisp and fresh. Replaced annually as part of the standard service.

5
Alkaline Remineralisation Filter
Post-filter — pH 7.5–8.5, minerals added
Pure RO water is slightly acidic and stripped of dissolved minerals. This stage passes water through calcium, magnesium and potassium-rich media to raise the pH to 7.5–8.5 and reintroduce beneficial electrolyte minerals. The result is water that tastes smooth and naturally fresh rather than flat — the same treatment used in premium bottled alkaline water. Replaced annually.
