PURETEC ULTRA Z FILTRATION
Puretec Z18 Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs the Puretec Z18 under sink water filter across eligible Brisbane, Gold Coast and surrounding South East Queensland service areas.
The current Puretec Z18-LF is a compact quick-change drinking-water filtration system designed for mains and town water. It combines Puretec's Ultra Z filtration technology with a dedicated DFU180 long-reach high-loop faucet so filtered drinking water is delivered separately from the existing kitchen mixer.
The Z18 uses the Puretec Z1-R cartridge with an advanced three-stage filtration process and a nominal 0.1-micron rating. Puretec positions the system to reduce sediment, chlorine, chemicals, bad taste and odour while providing protection against cysts and bacteria including E. coli.
Puretec Z18 at a glance: Z18-LF quick-twist under sink system, Z1-R replacement cartridge, DFU180 long-reach high-loop faucet, 0.1-micron nominal filtration, three-stage Ultra Z treatment, 0–5 L/min flow, 172–520kPa pressure range, 0–38°C temperature range, 23,000-litre rated capacity, ½" BSP connection, 12.5mm tap-hole requirement and current 10-year Puretec system warranty.
Puretec Z18 Supply & Installation at a Glance
0.1 Micron Filtration
Puretec publishes a nominal 0.1-micron filtration rating using its Ultra Z membrane technology.
3-Stage Filtration
The all-in-one Z1-R cartridge combines multiple treatment stages inside one compact quick-change cartridge.
Dedicated Designer Faucet
The Z18 includes Puretec's DFU180 long-reach high-loop faucet for filtered drinking water.
Quick-Twist Servicing
The valve-in-head design allows hygienic cartridge replacement without opening a traditional filter housing.
What Is the Puretec Z18?
The Puretec Z18 is a premium single-cartridge under sink drinking-water system using Puretec's Ultra Z technology.
Rather than using multiple conventional housings, the Z18 combines its treatment stages inside the Z1-R quick-change cartridge. This allows the system to remain compact while still providing sediment reduction, carbon treatment and fine membrane filtration.
Filtered water is delivered through its own dedicated faucet rather than through the existing kitchen mixer.
The Z18 package includes the filter, designer faucet and normal plumbing installation fittings required for a standard installation, subject to the actual site conditions beneath the sink.
How Does Ultra Z Filtration Work?
The Z18 uses an advanced three-stage treatment process inside the Z1-R cartridge.
Stage 1 – Clarification
The first stage reduces sediment, rust, sand, silt, algae and other particulate material before the water reaches the finer treatment stages.
Stage 2 – Carbon Treatment
Carbon filtration helps reduce chlorine, chloramine, unpleasant taste, odour and selected chemicals.
Stage 3 – Ultra Z Membrane
The final Ultra Z membrane filters down to a nominal 0.1 micron and provides protection against cysts and bacteria such as E. coli.
Why Choose the Puretec Z18?
Fine 0.1-Micron Filtration
The Ultra Z membrane provides substantially finer filtration than conventional sediment-and-carbon drinking-water systems.
Compact Single Cartridge
The Z18 combines three treatment stages in one cartridge rather than requiring several full-size filter housings.
Quick-Twist Cartridge Change
The valve-in-head design isolates the filter during cartridge replacement for cleaner servicing.
23,000-Litre Rated Capacity
Puretec's Z18 specification lists a rated cartridge capacity of approximately 23,000 litres, subject to water quality and usage.
Flexible Mounting
The Z1 filter assembly can be mounted horizontally or vertically, helping it fit around existing under-sink plumbing.
Dedicated Filtered-Water Outlet
The DFU180 faucet keeps filtered drinking water separate from normal hot and cold kitchen-mixer use.
PRODUCT SUITABILITY
Is the Puretec Z18 Right for Your Home?
A Good Choice If...
You want premium drinking-water filtration through a dedicated tap and prefer finer 0.1-micron treatment over a basic sediment-and-carbon system.
Consider the Z12 If...
You want the same Ultra Z filtration platform but prefer the different DFU130 faucet supplied with the Z12 package.
Consider Reverse Osmosis If...
You specifically want treatment targeting dissolved contaminants such as fluoride, selected heavy metals or PFAS beyond the published Z18 treatment scope.

The 0.1-micron rating is nominal. Cartridge life and the published 23,000-litre capacity can vary according to water quality, contaminant loading and actual usage.
Z1-R Replacement Cartridge
The Z18 uses the Puretec Z1-R Ultra Z Platinum replacement cartridge.
The cartridge combines the system's treatment stages inside one quick-change package rather than using separate conventional filter housings.
Puretec's valve-in-head design shuts off the water path during cartridge removal, allowing a cleaner cartridge replacement process with less water spillage.
Puretec specifies genuine Z1-R replacement cartridges for continued operation and warranty compliance.
Horizontal or Vertical Mounting
The Z18 can be installed with the filter assembly mounted horizontally or vertically.
This flexibility can help where kitchen cupboard plumbing, shelves, waste traps or storage restrict the available mounting position.
The Z1 filter itself measures approximately 290mm high × 90mm wide, with a cartridge diameter of approximately 77mm.
The final installation position still needs enough access for the cartridge to be released and replaced during future servicing.
DFU180 Dedicated Filtered-Water Faucet
The Z18 includes Puretec's DFU180 designer high-loop faucet.
This provides filtered drinking water from its own outlet while the existing kitchen mixer continues to supply ordinary hot and cold water.
A separate faucet also means the Z1-R cartridge is primarily used for drinking and food-preparation water rather than every litre used through the kitchen mixer.
Puretec specifies a 12.5mm diameter tap hole, so the sink or benchtop needs a suitable mounting position.
Multifunction Control Valve
Puretec's Z18 installation package includes a multifunction control valve manufactured from chrome-plated brass.
The valve incorporates pressure reduction, anti-water-hammer functionality and dual-check protection.
This helps provide an appropriate controlled supply to the filter and forms part of Puretec's standard installation arrangement.
The complete system still needs to operate within the published 172–520kPa pressure range.
What Does the Puretec Z18 Reduce?
Puretec publishes the Z18 for reduction or protection against a broader range of water-quality issues than a simple carbon drinking-water filter.
Sediment
Rust, sand and silt
Chlorine
Chloramine
Bad taste
Odours
Selected organic chemicals
Selected pesticides
Giardia and Cryptosporidium cysts
Bacteria including E. coli
Puretec's published material states reduction of 99.9% Giardia and Cryptosporidium cysts.
The system should still be used within Puretec's stated water-source conditions and should not be presented as a substitute for a treatment system designed for untreated microbiologically unsafe water.
