01–02 / HANDLE CARTRIDGE
PP Cotton → ACF Carbon Fibre
The first two stages sit in the handle cartridge. They are planned to address everyday particulate, odour and organic-compound considerations before water reaches the head cartridge.

THE PLANNED WATER PATH
03–05 / HEAD CARTRIDGE
KDF-55 → Chelating Resin IDA → Vitamin C
The final three stages sit in the head cartridge, completing the intended system sequence before water leaves the showerhead.
01
PP Cotton
Physical pre-filtration
The first layer is designed as a physical pre-filter for visible sediment and suspended particles encountered along the final water path.
02
ACF Carbon Fibre
Adsorptive material layer
A carbon-fibre layer selected around odour and organic-compound considerations within the planned filtration architecture.
03
KDF-55
Redox media layer
A copper-zinc redox medium located after carbon fibre as part of the system’s chlorine and selected-metal water-path considerations.
04
Chelating Resin IDA
Fine treatment layer
A chelating-resin layer positioned after KDF-55 for fine-treatment and ion-binding considerations within the engineered sequence.
05
Vitamin C (Sodium Ascorbate)
Finishing stage
The final Vitamin C stage is selected around residual-chlorine water-path considerations before water leaves the showerhead.
COMPLETE FILTER SET
Two cartridges. Replaced as one system.
Phase 1 is planned as an integrated handheld showerhead with two internal cartridges. The Handle Cartridge and Head Cartridge are supplied and replaced together as one Complete Filter Set on a planned 90-day rhythm.
EVIDENCE BEFORE CLAIMS
Material notes are not performance promises.
The material roles on this page describe product architecture and intended engineering considerations. Pureis will not publish quantified chlorine or metal-reduction claims until relevant independent finished-product testing has been completed.

CARE & REPLACEMENT
A simple routine for the system.
The planned Phase 1 rhythm is one Complete Filter Set every 90 days. The Handle Cartridge and Head Cartridge are intended to be replaced together.
