LifeStraw Personal Water Filter Straw

The LifeStraw personal water filter lets you drink directly from streams, lakes, and puddles with a hollow fiber membrane that removes 99.9999% of bacteria and 99.9% of protozoa — no pump, no tablets, no batteries, and no expiration date on the technology.

The 0.2-micron hollow fiber membrane filters up to 1,000 gallons before the membrane self-blocks, signaling it's spent before contaminated water can pass through. It weighs just 2 oz and fits in any shirt pocket, vest, or first aid kit — making it a practical emergency backup even when carrying a gravity or pump filter. Certified to EPA and NSF standards for bacteria and protozoa removal, effective against Giardia, Cryptosporidium, E. coli, and similar waterborne pathogens common in backcountry water sources worldwide.
