Spectrum Z1 Under Sink Reverse Osmosis System
The Spectrum Z1 is a compact, powered under-sink reverse osmosis system designed for homes and light-commercial applications where cupboard space, straightforward servicing and reliable purified-water production matter.
Fast dispensing without relying on a conventional storage tank.
Thin-film composite RO membrane for reduction of dissolved substances.
Efficient water recovery under suitable operating conditions.
A slim footprint designed to preserve valuable under-sink space.
High-Output RO Filtration in a Slim Cabinet
At only 130 mm wide, the Z1 combines a compact cabinet with an integrated booster pump and a rated product-water flow of 2 litres per minute. The system is designed for municipal water supplies and operates at a feed pressure of 1–4 bar.
- Integrated booster pump supports consistent RO production
- Push-fit connections simplify installation and servicing
- Automatic flushing helps maintain membrane performance
- Filter-life indicators show when cartridges require attention
How the Spectrum Z1 Filters Your Drinking Water
The Z1 uses two replaceable cartridges to provide four treatment stages. The Z1-C combines three functions in one cartridge, while the Z1-M contains the reverse osmosis membrane.
Sediment Filtration
Captures particulate material such as dirt, sand and rust before it reaches the finer filtration stages.
Pre-Carbon
Reduces chlorine before the RO membrane, helping protect the chlorine-sensitive membrane.
Reverse Osmosis
The thin-film composite Z1-M membrane reduces dissolved substances and microscopic impurities.
Post-Carbon
Final activated-carbon treatment adsorbs residual tastes and odours before water reaches the tap.
Designed for Straightforward Under-Sink Installation
The Z1 connects to the cold-water supply, a drain connection and a nearby electrical socket. A separate brushed stainless-steel drinking-water tap is supplied and requires a 12 mm mounting hole.
Important: The system must be connected to cold water only. Where incoming pressure exceeds 4 bar, the manufacturer specifies that a pressure-reducing valve should be fitted.
Twist-and-Lock Cartridges with Filter-Life Monitoring
The front-access cartridge arrangement is designed to make routine servicing straightforward. Indicator lights monitor the Z1-C and Z1-M filter life, while automatic rinse cycles operate at power-up, after extended production and after prolonged standby.
Typical service guide: 6–12 months
Typical service guide: 12–24 months
Actual cartridge life varies with feed-water quality, usage and operating conditions.

Spectrum Z1 FAQs
Does the Spectrum Z1 need a storage tank?
The manufacturer specifies a 2 L/min product-water flow and the system is supplied as a compact powered RO module rather than a conventional RO system with a separate storage tank.
Does the Spectrum Z1 require electricity?
Yes. The Z1 contains an integrated booster pump and requires a nearby electrical supply. The specified electrical input is 100–240 V AC, 50/60 Hz.
How often are the Spectrum Z1 filters replaced?
The manufacturer's service guide recommends approximately 6–12 months for the Z1-C cartridge and 12–24 months for the Z1-M RO membrane. Actual life depends on water quality and usage.
What water pressure does the Z1 require?
The specified operating range is 1–4 bar. The manufacturer states that a pressure-reducing valve should be used where supply pressure exceeds 4 bar.
What comes with the Spectrum Z1?
The system includes the RO module, Z1-C and Z1-M cartridges, power transformer, inlet valve, drain fittings, brushed stainless-steel drinking-water tap, connectors and installation tubing.
