What it does
Two treatment goals, one tank
- 01
Filtration plus softening
KDF55, catalytic carbon and softening resin sit in separated layers inside a single tank, so each layer can focus on its own treatment goal.
- 02
Designed to reduce a lot
It is designed to reduce hardness minerals, chlorine, chloramines, volatile organic compounds, trihalomethanes, selected dissolved metals, tastes and odors.
- 03
Metered regeneration
Regeneration responds to water use, and the brine tank recharges the resin so it can keep softening.
- 04
Needs salt, power and a drain
All three are part of the install, so the spot it goes in has to offer them.

Questions about this system
What does 2-in-1 mean here?
Filtration and softening share a single tank. KDF55, catalytic carbon and softening resin work in separated layers, so each one can focus on a different concern.
What does Flow X4 need to run?
Salt for the brine tank, electric power and a drain.
How does it know when to regenerate?
The control is metered, so regeneration responds to your water use rather than a fixed timetable.
How do I choose between Purest Flow X4 and Purest Hyper Flow?
Both are 2-in-1 systems with one tank and a brine tank. Your own water decides which one fits, and the free water test is how that gets decided.
