How Natural Pure makes water clean, crisp, and refreshing.
Explore the purification journey from incoming water through pre-filtration, reverse osmosis, UV treatment, final filtration, and fresh dispensing.
The Purification Journey
A visual look at how water moves through each stage before it reaches your bottle.
Follow the water from start to finish.
Select a stage below to see what happens as the water is prepared for refill.
Stage 1: Pre-Filtration
The process starts with sediment and activated carbon filtration. This helps remove particles and helps reduce chemicals such as chlorine before the water reaches the membrane stage.
Stage 2: Pressure
The water is pressurized and directed into the vessel that holds the thin-film reverse osmosis membrane. Pressure is what allows the system to separate purified water from dissolved material.
Stage 3: The Membrane
The RO membrane is the heart of the process. It helps remove dissolved solids and many impurities, producing the clean, crisp water customers expect from Natural Pure.
Stage 4: UV Sterilization
After reverse osmosis, the water passes through an ultraviolet light unit. This stage helps address bacteria and viruses as part of the complete purification process.
Stage 5: Final Filtration and Fresh Dispensing
Once treated, the water is filtered again and held until it is dispensed fresh into your bottle at the refill station.
