How it works
What is a whole house water filter?
A whole house (point-of-entry) system is installed where the water supply enters the property, so every tap, shower and appliance receives filtered water — not just the kitchen sink.
-
Step 1: Mains water enters
The system is plumbed in where the water supply enters the property, through a 25 mm brass inlet.
-
Step 2: Three stages of filtration
Water passes through three full-size 20 × 4.5 inch cartridges — 5 micron sediment, then 1 micron carbon with scale reduction, then 1 micron carbon — with a pressure gauge on every stage.
-
Step 3: Filtered water at every tap
Up to 50 litres per minute of filtered water flows on to every tap, shower and appliance in the home.
