The Membrane Solutions filter straw is a hollow-fiber personal water filter you drink through directly, no pump or battery needed. It weighs about 2 ounces and is rated for up to 5,000 liters, with a flow rate around 500 ml per minute. It sits in the same class as the Sawyer Mini and LifeStraw: lighter and simpler than a pump filter, but it removes microbes only, not chemicals, salt or viruses at the smallest scale. It suits hikers, campers and emergency kits who want a backup filter that takes no space.

Owners treat it as a cheap, light backup filter that works for stream and lake water on day hikes and in emergency kits. Most praise the weight and simplicity; complaints center on slow flow as the filter loads up and the limits of what it removes.
