Purist technology shields the inside of the bottle from any bad taste, mold, or staining. Nothing sticks, so your bottle stays clean and your water tastes pure. The Purist technology naturally shields the inside of your bottle. Exactly the same way a lotus leaf shields itself to maintain its purity. Technology truly inspired by nature.
