The Purist water bottle is the next generation of plastic water bottles, combining the ease of drinking that plastic provides, with the clean taste of a glass bottle. Utilizing technology developed from the Lotus plant's leaf, this bottle's interior has an extremely low surface tension, due to the infusion of silicon dioxide into the polyethylene shell. This results in a bottle that that offers a much more 'pure' drinking experience, no matter your drink of choice. Recommended cleaning procedure is simply a rinse with warm water and mild detergent, or the top shelf of automatic dishwashers. It is not recommended to use abrasives to clean these bottles. 100% Recyclable.
