Katadyn Katadyn Pocket Water Filter for Camping - 8013618 in fantastic shape, only used once in reasonably clean water. Includes the original packaging and accessories, including a packet of activated charcoal. There are a few little bits of activated charcoal here and there, but they are just from the post filter which still has some activated charcoal in it. This pump is made in Switzerland and extremely high-quality, definitely the gold standard for durability and functionality when it comes to water filtering.
