The RapidPure Purifier+ Plastic Bottle is designed to quickly purify water as you drink. It uses a proprietary filtration system combining UltraCeram® and OpenPore technology, which protects against viruses, bacteria, and parasites. The bottle has a flip-top lid, holds a liter of water, and is compatible with most wide-mouthed bottles. This system requires no priming, squeezing, or backflushing—simply fill and drink.
