The Finerfilters Water Filter Straw is a hollow-fiber microbiological filter you drink through directly from a lake, stream or tap. It has no chemicals, batteries or moving parts, weighs about 90 grams and claims a high flow rate. It suits hikers, campers, backpackers and emergency kits. Against pump filters and gravity systems it is lighter and simpler, but it does not claim to remove salt, viruses or heavy metals, so it is a backcountry and emergency tool rather than a desalinator or a virus barrier.
