The Purewell is a personal water filter straw with a three-stage filter that the brand says removes almost all bacteria, parasites and microplastics from backcountry water. It screws onto any 28mm-threaded bottle, cup or glass, and the ends come off for cleaning. The brand rates it for up to 792 gallons (3,000 liters) before replacement. It suits hikers, campers and emergency kits that want a light, bottle-compatible filter; rivals like the Sawyer Squeeze and LifeStraw focus on squeeze bags or direct sipping, so the threaded mount is the main difference. Buyers rate it well, though the sample of ratings is small.
