PURETEC ULTRA Z UNDER-SINK FILTRATION
Puretec PureMix Z6 Under-Sink Water Filter
The Puretec PureMix Z6 is a high-flow inline under-sink filtration system designed specifically for mains water. It connects to a compatible existing two-way kitchen mixer so filtered cold water can be supplied without installing a separate drinking-water tap. :contentReference[oaicite:0]{index=0}
The current PUREMIX-Z6-LF uses Puretec's Z6-R quick-twist cartridge with Ultra Z filtration technology, a nominal 0.1 micron rating, a manufacturer-listed flow rate of 9.5 L/min and capacity of 60,000 litres. :contentReference[oaicite:1]{index=1}
Puretec lists the system for reduction of sediment, chlorine, unwanted taste and odour, filterable cysts and bacteria including E. coli, while the current user guide still requires appropriate source-water quality and warns against use on microbiologically unsafe or unknown water without adequate disinfection. :contentReference[oaicite:2]{index=2}
Quick answer:
the PureMix Z6 is a 0.1 micron mains-water under-sink filter designed to connect to an existing compatible kitchen mixer. It provides up to 9.5 L/min, uses one Z6-R quick-twist cartridge and does not require a separate filter tap, electrical supply or filtration waste-water drain. :contentReference[oaicite:3]{index=3}

HOW IT WORKS
Three Levels of Ultra Z Filtration
The PureMix Z6 uses one replaceable cartridge containing three filtration functions rather than three separate filter housings.
Fine Particle Filtration
Filters sediment, dirt and other suspended particles down to a nominal 0.1 micron.
```
Carbon Treatment
Reduces chlorine together with unwanted taste and odour from compatible mains-water supplies.
Cyst & Bacteria Protection
Puretec lists protection against filterable cysts and bacteria such as E. coli through its Ultra Z filtration technology.
```
([Puretec Pty Ltd][1])
NO SEPARATE FILTER TAP REQUIRED
Connect Filtered Cold Water to Your Existing Mixer
The PureMix Z6 is designed to connect to an existing compatible two-way mixer tap on the cold-water supply.
This means a separate filtered-water faucet is not required in the standard PureMix installation, which can be useful where an additional tap hole is not wanted.
Puretec allows the filter assembly to be mounted vertically or horizontally beneath the sink, helping it fit around existing cabinet storage and pipework. :contentReference[oaicite:6]{index=6}
0.1 MICRON FILTRATION
Fine Filtration for Mains Water
Puretec lists the Z6-R with a nominal filtration rating of 0.1 micron.
The manufacturer currently lists treatment including:
- Sediment
- Dirt and suspended particles
- Chlorine
- Unwanted taste
- Unwanted odour
- Giardia cysts
- Cryptosporidium cysts
- Bacteria including E. coli
- Trihalomethanes as listed by Puretec

MICROBIOLOGICAL CLAIMS
Understand What Puretec's Current Guidance Says
Puretec markets the Z6 as providing protection against bacteria such as E. coli and filterable cysts through its Ultra Z filtration technology. :contentReference[oaicite:8]{index=8}
The Z6 should not be treated as universal source-water disinfection.
Puretec's current user guide states that the Z6 is designed for mains water and warns not to use the system on microbiologically unsafe water or water of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that can contain filterable cysts. :contentReference[oaicite:9]{index=9}
MAINS WATER ONLY
Puretec Distinguishes the Z6 From the Z7
The current Puretec user guide states that the PureMix Z6 is designed to operate with mains water.
Puretec separately identifies the Z7 for mains, rain, harsh and rural supplies. The Z6 should therefore not automatically be marketed as a rainwater or rural-water filter simply because another PureMix model supports those applications. :contentReference[oaicite:10]{index=10}
FLOW RATE
9.5 Litres Per Minute
Puretec currently lists the PureMix Z6 at 9.5 L/min.
Actual flow at the mixer can still vary according to incoming pressure, tap design, plumbing, fittings and cartridge condition.
A listed flow rate is not a guarantee of zero pressure change.
Any inline filter adds some hydraulic resistance, and available flow depends on the complete installation rather than the cartridge specification alone.
([Puretec Pty Ltd][1])
CAPACITY
60,000 Litre Manufacturer-Listed Capacity
Puretec currently lists the PureMix Z6 with a capacity of 60,000 litres. :contentReference[oaicite:12]{index=12}
The current Z6/Z7 user guide states that this capacity is based on inlet chlorine of approximately 2 ppm ±10%. Water quality and treatment demand can shorten practical cartridge life. :contentReference[oaicite:13]{index=13}
Do not use 60,000 litres as the only replacement trigger.
Puretec's current model-specific guide instructs users to replace the Z6-R at least every 60,000 litres or 6 months, whichever occurs first, or sooner if taste, odour or flow changes are detected. :contentReference[oaicite:14]{index=14}

CONNECTION
15 mm Cold-Water Mixer Connection
The PureMix Z6 uses a 1/2" BSP / 15 mm connection and is installed on the cold-water line supplying the kitchen mixer.
Puretec's current user guide states that the installation kit is designed to connect to a 15 mm male-thread arrangement and includes an extension kit where extra hose length is required. :contentReference[oaicite:16]{index=16}
MOUNTING
Horizontal or Vertical Installation
Puretec allows the Z Series filter to be mounted either vertically or horizontally.
The current user guide specifies a minimum of approximately 70 mm cartridge-change clearance and advises leaving additional free space around the system so stored items cannot accidentally knock the cartridge out of its locked position. :contentReference[oaicite:17]{index=17}
- Vertical installation permitted
- Horizontal installation permitted
- Allow cartridge-removal clearance
- Keep fittings and tubing free from kinks
- Avoid direct sunlight
- Keep stored items away from the cartridge

VALVE-IN-HEAD DESIGN
Quick-Twist Z6-R Cartridge Replacement
The Z6-R uses Puretec's valve-in-head quick-twist format. The cartridge is removed with approximately a quarter-turn and the replacement cartridge locks into the head by rotating it back into position.
The head and cartridge alignment arrows should line up when the cartridge is correctly seated. :contentReference[oaicite:20]{index=20}
Follow the current user guide during servicing.
Although Puretec markets the valve-in-head design as simplifying cartridge changes, the current 2026 user guide specifically instructs users to shut off the water supply and release pressure before replacing the cartridge. :contentReference[oaicite:21]{index=21}
REPLACEMENT INTERVAL
60,000 Litres or 6 Months, Whichever Comes First
Puretec's current model-specific Z6/Z7 user guide instructs users to replace the Z6-R at least every 60,000 litres or 6 months, whichever occurs first.
Replacement should also occur sooner if there is a noticeable change in taste, odour or flow. Varying chlorine, sediment and organic-substance levels can affect service life. :contentReference[oaicite:22]{index=22}
General Puretec cartridge pages sometimes refer to 6–12 month replacement periods, but the current Z6-specific user guide provides the more specific 6-month / 60,000-litre instruction for this model. :contentReference[oaicite:23]{index=23}
