Introducing Purist: As pure as drinking from a glass—with all the advantages of a flexible bottle.
In creating the next generation of water bottles, our team set out to solve a puzzle that has challenged engineers for years: How can we combine the two most desired elements in the ideal water bottle, the flexibility and safety of a sports bottle with the pure taste of drinking from a glass?
To help solve this, we looked to nature for inspiration and found the solution in the lotus flower.
Just as the lotus leaf sheds water and contaminants, so does Purist, through low surface tension shielding the inside of your bottle from odor, staining, and mold build-up. With a simple rinse of the bottle, Purist ensures that water from the bottle does not taste like plastic or the previous liquid.
In re-creating the surface of a lotus leaf, we wanted a safe, natural solution, so we turned our attention to silicon dioxide.
Silicon dioxide is an inert compound made from two of the most abundant elements in the earth’s crust: silicon (not to be confused with the chemical “silicone”) and oxygen. When combined they form silicon dioxide (SIO2).
Occurring naturally in plant-based foods such as apples, oranges, cucumbers, and celery, silicon dioxide is an indispensible part of the food we eat. And along with calcium and vitamins, it is important for the natural development of bones and the maintenance of healthy skin.
Silicon dioxide is also found in nature as sand and quartz and is used in the production of glass beverage bottles and ceramics such as earthenware, stoneware, and porcelain. These properties make it an excellent barrier for a water bottle, providing a natural, safe shield, while delivering the pure taste only glass can offer.
In fact, this barrier is so effective that the medical industry uses silicon dioxide to create an ultra-sterile surface for tests that cannot be compromised with even the slightest impurities.
So, with technology borrowed from nature, we have created a new era in bottle performance.
Each Purist bottle is infused with silicon dioxide, which forms a protective glass-like barrier inside the bottle. This prevents odors, stains, and mold from attaching to the inner surface.
This Purist infusion is added after the bottle has been molded and is chemically bonded to the bottle wall. The barrier is an extremely thin 20 nanometers—over 5,000 times thinner than a human hair.
By infusing the silicon dioxide, no compromise is made to the structure, and the bottle remains totally flexible for easier drinking. It will not delaminate or fall off, even when the bottle is flexed over and over.
Even in extreme conditions – such as tomato sauce left in the bottle overnight-Purist shields the bottle from taste, smell and staining. Nothing sticks, so your bottle stays clean and your water tastes pure.
