The Pure Water Filter Straw is a pocket-size personal water filter that removes contaminants down to 0.01 microns, including a claimed 99.99% of them. It has no expiration date, needs no power, and weighs about 2 ounces, so it works in a blackout or on a trail. Each filter is rated for up to 400 gallons. It suits campers, hikers and households building an emergency kit. Against pump filters and gravity systems it is lighter and simpler, but it filters by mouth or through the included water bag, so it is slower for large groups. Buyers value it as backup that works when everything else fails.
