What it removes

Sediment, dirt and rust
Larger sediment, dirt, rust and suspended particles.
-
Fine silt
Fine sediment and silt down to 1 micron.
-
Bacteria and viruses
The UV stage treats bacteria, viruses and other micro-organisms, with no chemicals added.
Taste or odour a concern? The Ultra III Shield adds a carbon block stage.
How it works
Two stages, then UV
Water passes through each filter stage in order, then the UV chamber, before it reaches every tap in the house.
- Water in
Stage 1
Coarse sediment
Pleated sediment cartridge
20" Jumbo20 micronWaimana 20PL20
Captures larger sediment, dirt, rust and suspended particles to protect the finer stages.
Stage 2
Fine sediment
Polyspun sediment cartridge
20" Jumbo1 micronWaimana 20PP01
Captures the fine silt and particles that get past Stage 1, so the water is clear before it reaches the UV.
Stage 3
UV treatment
48W UV chamber
30 mJ/cm²Flow-activated
The filtered water passes through the UV chamber, which treats it for bacteria, viruses and other micro-organisms with no chemicals added. The lamp only runs while water is flowing.
- Filtered, UV-treated water to every tap
UV treatment

- UV needs clear water. The filter stages before it remove the sediment that would block the UV light.

Common questions
What does the Shield add?
The Ultra II Shield has the same filtration, UV treatment and flow rate as the Ultra II. It adds a protective cover and a pressure gauge, so it suits indoor and outdoor installation.
What does the pressure gauge show?
It shows the water pressure in the system.
What does flow-activated UV do?
The lamp only switches on when water is flowing. That lowers power use, extends lamp life and stops water warming in the chamber.
Does UV change the taste of the water?
No. UV treats the water without adding chemicals or changing its taste.
How often do I change the cartridges and the lamp?
Every 12 months. The service kit has the cartridges and the UV lamp, so you change them together. Clean the quartz sleeve at each lamp change.
Still not sure?
