Six stage RO plus UV water purification process
Our Process

Six Stages Between the Source and Your Glass

Every drop we bottle passes the same treatment line, and each batch is logged with its own batch number so it can be traced back later.

01
Sediment Filter

Sand, silt and rust are held back at the very first pass.

02
Carbon Filter

Chlorine, odour and organic taste are stripped out.

03
RO Membrane

Dissolved salts and heavy metals are pushed to drain.

04
UV Sterilisation

Bacteria and viruses are neutralised without chemicals.

05
Mineral Dosing

Calcium and magnesium are added back for taste.

06
Ozone & Sealing

Jars are ozonated, filled and sealed tamper-proof.
