PURETEC PUREMIX UNDER-SINK FILTRATION
Puretec PureMix Z7 Under-Sink Water Filter
The Puretec PureMix Z7 is a high-flow under-sink filtration system designed for mains, rain, harsh and rural water supplies where higher sediment levels or lower available pressure can influence filter selection.
The current PUREMIX-Z7-LF uses the genuine Puretec Z7-R 15-inch quick-twist cartridge with a nominal 1 micron rating, a manufacturer-listed flow rate of 9.5 L/min at 420 kPa and a listed capacity of up to 63,500 litres.
Puretec's Z Plus filtration technology combines sediment, chlorine, taste and odour treatment with cyst reduction, internal bacterial-growth inhibition and Anti-scaling protection in one replaceable cartridge.
Quick answer:
the PureMix Z7 is designed for customers who want filtered cold water through an existing compatible kitchen mixer without necessarily adding a separate drinking-water tap. It is particularly suited to higher-sediment, harsh, rural and rainwater applications where the source water is otherwise appropriate for the system.

WHAT DOES IT DO?
Multi-Function Z Plus Filtration in One Cartridge
The PureMix Z7 uses one quick-twist Z7-R cartridge containing several treatment functions rather than multiple separate filter housings.
Particles
Reduces sediment, dirt, rust, sand, silt, algae and other suspended material down to a nominal 1 micron.
```
Chlorine & THMs
Puretec lists chlorine and trihalomethane reduction among the current Z7 treatment functions.
Cyst Reduction
Puretec lists Giardia and Cryptosporidium cyst reduction for the Z7-R within the cartridge's specified conditions.
```
FOR HARSHER WATER CONDITIONS
Designed for Mains, Rain, Harsh & Rural Water
Puretec specifically positions the Z7 for applications with higher sediment or harsher water conditions, including rural supplies, rainwater and areas with older pipe infrastructure.
Its 1 micron Z7-R cartridge combines particulate and carbon treatment while maintaining a manufacturer-listed filtered-water flow of up to 9.5 L/min at 420 kPa.
Source-water suitability still needs to be considered. The Z7 is not a substitute for required microbiological disinfection where the incoming water is unsafe or of unknown quality.
PARTICLE FILTRATION
Nominal 1 Micron Filtration
Puretec lists the Z7 at a nominal 1 micron filtration rating.
- Sediment reduction
- Dirt reduction
- Rust reduction
- Sand reduction
- Silt reduction
- Algae reduction
- Giardia cyst reduction
- Cryptosporidium cyst reduction
Puretec defines removal terminology as significant reduction rather than necessarily 100% removal.
CARBON TREATMENT
Chlorine, Taste, Odour & THM Reduction
The Z7-R includes carbon treatment for common mains-water concerns.
Chlorine
Puretec lists chlorine filtration as a primary Z7 treatment function.
```
Taste & Odour
The cartridge is designed to reduce unwanted taste and odour associated with compatible water supplies.
Trihalomethanes
Puretec currently lists trihalomethane, or THM, reduction for the PureMix Z7.
```
Z PLUS TECHNOLOGY
Internal Bacterial-Growth Inhibition
Puretec's Z Plus technology is designed to inhibit bacterial growth within the filtration system.
This function helps manage growth within the cartridge itself, but it should not be interpreted as universal bacterial removal or source-water disinfection.
The Z7 is not Puretec's dedicated E. coli filtration solution.
Puretec specifically notes that the Z7 may not be suitable where bacteria such as E. coli are a concern. Microbiologically unsafe or unknown water requires adequate disinfection before or after the system.
ANTISCALE PROTECTION
Helps Manage Mineral Build-Up
Puretec incorporates Anti-scaling protection into the Z7-R cartridge.
This function is intended to help reduce mineral build-up within compatible applications.
Anti-scaling protection is not the same as conventional water softening.
The PureMix Z7 does not use ion-exchange resin, salt regeneration or a brine tank and should not be described as removing all dissolved hardness minerals.
FLOW RATE
9.5 L/min at 420 kPa
Puretec lists the PureMix Z7 at 9.5 litres per minute at 420 kPa.
Actual outlet flow can vary according to incoming pressure, plumbing configuration, mixer design, source-water conditions and cartridge loading.
The system's high-flow format allows the filtered cold-water supply to feed a compatible kitchen mixer rather than requiring a low-flow dedicated drinking tap in every installation.
CAPACITY
Up to 63,500 Litres
Puretec lists the Z7 with a filtration capacity of up to 63,500 litres.
This capacity is based on inlet chlorine at 2 ppm ±10% and should not be treated as a guaranteed service life under every water condition.
Water Quality
Higher sediment or chemical loading can shorten practical service life.
```
Water Use
Higher household consumption moves the cartridge toward its rated capacity more quickly.
Service Interval
Puretec recommends cartridge replacement every 6–12 months depending on water quality and usage.
```
EXISTING MIXER CONNECTION
No Separate Filter Tap Required
Puretec designed the PureMix Z7 to connect to a compatible existing kitchen mixer so the cold-water supply can pass through the filter before reaching the tap.
This can be useful where a separate filtered-water faucet is not wanted or where drilling an additional tap hole into a benchtop is undesirable.
- Connects to compatible mixer arrangements
- 1/2" BSP / 15 mm connection
- No dedicated filter tap required for the standard configuration
- No waste-water connection required
- No electrical power required
MOUNTING
Horizontal or Vertical Installation
Puretec allows the PureMix Z7 to be installed either vertically or horizontally inside the cabinet.
Vertical Mounting
Puretec's current specification indicates approximately 500 mm high × 215 mm wide should be allowed.
```
Horizontal Mounting
Allow approximately 215 mm high × 500 mm wide for horizontal installation.
```
Allow additional clearance for tubing, fittings and quick-twist cartridge replacement rather than designing the cabinet around the cartridge dimensions alone.
SYSTEM SIZE
Compact 15-Inch Cartridge Format
Puretec's current product specification identifies the Z7-R as a 15-inch cartridge.
Published product drawings show the assembled filter at approximately:
- 405 mm overall height in the front-view drawing
- Approximately 93 mm cartridge-width profile
- Approximately 109 mm total side-view depth at the head

Z7-R REPLACEMENT
Quick-Twist Cartridge Servicing
The PureMix Z7 uses Puretec's quick-twist replacement format, allowing the Z7-R cartridge to be removed from the valve-in-head assembly during servicing.
- Shut off the water supply
- Release pressure through the tap
- Unlock the used Z7-R cartridge from the head
- Remove the used cartridge
- Install the genuine replacement Z7-R
- Lock the new cartridge correctly into the head
- Restore water gradually
- Flush according to Puretec's instructions
- Check the filter and fittings for leaks
- Confirm normal filtered-water flow
REPLACEMENT INTERVAL
Replace the Cartridge Every 6–12 Months
Puretec recommends replacing the Z Series cartridge approximately every 6–12 months, depending on water quality and usage.
Replacement can be required earlier where the cartridge reaches its treatment capacity, incoming sediment loading is high or filtered-water flow reduces significantly.
Do not rely only on the 63,500 litre figure.
The manufacturer's time-based service interval and the actual source-water conditions remain important when deciding when the cartridge should be changed.
