Add-on

How it goes
From the test to Purest UV

- 01
Free water test
We test your water for hardness, chlorine, TDS, pH, iron and manganese. It costs nothing and it carries no obligation.
- 02
A recommendation
Your results decide the system. You see a fixed price after the test, never before it.
- 03
Installation
Purest UV is fitted on the main line, after your filtration system.
- 04
Treated water, every day
Water that has been filtered and then treated with ultraviolet light reaches every tap.
Where it fits
Chosen from your water, not from a catalogue.
UV is an add-on, not a replacement for filtration. It goes on the main line after a filtration system, so the water it treats has already been filtered.
Every recommendation starts with the free water test, and the price is fixed after the test, never before it.

Questions about this system
Is UV a filter?
No. UV treats bacteria and viruses. It does not remove sediment, chlorine or hardness, which is why it goes after filtration.
Why does it go after filtration?
It installs on the main line after filtration, so the water passing the lamp has already been filtered and the treated water is the water that reaches your taps.
