The Puretec Z6-R is the genuine quick-twist replacement cartridge for the Puretec PureMix Z6 under-sink water filtration system.
The PureMix Z6 is specifically designed for mains water and combines three filtration stages within a compact cartridge, including sediment filtration, carbon treatment and Puretec's Ultra Z filtration membrane.
The system provides a nominal filtration rating of 0.1 micron and is designed to reduce sediment, rust, sand, silt, algae, chlorine, chloramine, unwanted taste and odour while providing protection against specified cysts and bacteria such as E. coli.
The Z6-R is specifically designed as the replacement cartridge for the Puretec PureMix Z6 under-sink filtration system.
It should not automatically be substituted for other Puretec Z Series cartridges because different PureMix systems use different filtration technologies and water-supply applications.
Puretec specifies the PureMix Z6 for mains water supply.
This distinguishes it from models such as the PureMix Z7, which Puretec positions for mains, rain, harsh and rural water applications.
If the property uses rainwater, bore water, rural water or another non-standard supply, the filtration system should be selected for the actual source water rather than assuming the Z6 is suitable.
The PureMix Z6 uses three filtration stages to treat mains water before it reaches the kitchen mixer.
The first stage targets particulate material, the second provides chemical and taste-and-odour treatment, and the third uses Puretec's Ultra Z membrane for nominal filtration down to 0.1 micron.
Puretec states that the final filtration stage provides protection against specified cysts and bacteria such as E. coli. Puretec defines terms such as “removal” and “protection” as indicating significant reduction rather than necessarily 100% removal.
The first filtration stage is designed to remove particulate material and clarify the incoming water.
The system targets suspended sediment before water progresses through the later filtration stages.
Puretec identifies rust, sand and silt among the particulate material reduced by the first stage.
The sediment stage also targets algae and other particulate matter in the incoming mains-water supply.
The second stage provides carbon-based water treatment for substances associated with treated mains water.
Puretec specifies chlorine and chloramine reduction as part of the Z6 filtration process.
The filtration stage is designed to reduce unwanted taste and odour from the water supply.
Puretec also lists reduction of chemical pesticides and sulphur among the treatment functions of this stage.
The third stage uses Puretec's Ultra Z filtration membrane and has a nominal rating of 0.1 micron.
This fine filtration stage is designed to capture very fine particulate material and provide protection against specified cysts and bacteria, including organisms such as E. coli.
| Specification | Puretec PureMix Z6 / Z6-R |
|---|---|
| Replacement Cartridge | Z6-R |
| System Type | High-flow inline under-sink filtration system |
| Water Supply | Mains water |
| Filtration Stages | 3 stages |
| Nominal Micron Rating | 0.1 micron |
| Listed Flow Rate | 9.5 L/min at 420 kPa |
| Operating Pressure | 200–520 kPa |
| Operating Temperature | 0–38°C |
| Connection | 1/2" BSP / 15 mm |
| Cartridge Size | 15" |
| Listed Capacity | Up to 60,000 litres under Puretec's stated test conditions |
Puretec states that the capacity figure is based on specified inlet chlorine conditions. Actual cartridge life can vary with water quality, usage, flow and other operating conditions.
The PureMix Z6 is rated at 9.5 litres per minute at 420 kPa.
Actual flow at the mixer can vary with incoming pressure, plumbing layout, cartridge condition and other restrictions within the complete installation.
A noticeable reduction in filtered-water flow can be one indication that the Z6-R cartridge is approaching its service interval or that another part of the filtration installation requires attention.
Puretec lists the PureMix Z6 operating pressure range at 200–520 kPa.
Where incoming pressure exceeds the system requirement, the installation needs an appropriate pressure-control arrangement in accordance with the applicable Puretec installation requirements.
Replacing the cartridge will not correct plumbing pressure that sits outside the operating range of the complete filtration system.
Puretec lists the PureMix Z6 with a nominal capacity of up to 60,000 litres.
This figure is based on Puretec's stated test conditions and should not be treated as a guaranteed cartridge life in every property.
Actual service life depends on water quality, chlorine loading, sediment, household consumption and other operating conditions. The cartridge may therefore require replacement before the nominal capacity is reached.
Puretec recommends replacing the Z6-R approximately every 6–12 months, depending on water quality and usage.
Cartridge capacity and actual performance should also be considered rather than relying solely on a calendar date.
The Z6-R uses Puretec's quick-twist cartridge connection, allowing the replacement cartridge to be removed from and secured into the existing PureMix Z6 filter head without opening a conventional filter bowl.
The water supply should still be correctly isolated and system pressure released before replacement begins.
Puretec instructs users to flush the PureMix system for approximately 10 minutes after periods of non-use longer than two days.
This is separate from the normal flushing procedure required when a new cartridge is first installed.
The Z6-R is a replacement cartridge for an existing PureMix Z6 system. It does not include a new filter head, installation valve, hoses, bracket or complete filtration-system installation.
Puretec's installation instructions state that installation of the complete PureMix Z6 system must be completed by a licensed plumber.
Professional cartridge replacement may be available in eligible Installed Today service areas.
A cartridge replacement service can include removal of the existing Z6-R, installation of the new cartridge, inspection of accessible connections and a final check for leaks and normal filtered-water flow.
Damaged filter heads, valves, hoses, mixers, pipework or other plumbing components are separate where replacement or repair is required.
