Sediment Filter | Stage 1

Capture larger source-water debris first so downstream carbon, membrane, and DI stages can operate from a cleaner filtration foundation.

Carbon Block | Stage 2

Protect the membrane by handling chlorine, chloramine, and chemical load before the system moves into deeper purification work.

RO Membrane | Stage 3

Handle the heavy purification step by rejecting dissolved solids and preserving the clean-water path toward reliable 0 TDS output.
