Lifestraw Flex with Gravity Bag

Maximize protection and water throughput with this ultralight, compact gravity filtration system. LifeStraw Flex is built to provide safe drinking water in almost any environment. The 2-stage filter offers next level protection against bacteria, parasites, and microplastics while also expanding protection against lead and some chemicals. It can be used with the included gravity bag, as a straw, attached to a hydration pack, or with a plastic water bottle.

Stage 1: The hollow fiber membrane removes

• 99.999999% of bacteria (E. coli)

• 99.999% of parasites (Giardia, Cryptosporidium, etc.)

• 99.999% of microplastics

Stage 2: The activated carbon capsule reduces

• Lead and other heavy metals

• Chlorine

• Bad odor and taste

• Organic chemical matter

We believe that responsible manufacturing includes creating and maintaining a strong evidence base for our product claims and their intended impacts. All products undergo rigorous independent testing to meet or exceed protocols established by the US Environmental Protection Agency (EPA) and National Sanitation Foundation (NSF) We also built and run an ISO accredited water laboratory based in Vietnam that does quality validation and testing of all of our new and existing products.

• Hollow fiber membrane filter: 0.2 micron pore size. Removes 99.999999% of bacteria, 99.999% of parasites, and 99.999% of microplastics.

• Also removes turbidity (silt, sand, and cloudiness).

• Carbon fiber filter: Improves taste while reducing lead and other heavy metals, chlorine, and organic chemical matter such as pesticides, herbicides, and VOCs.

• Meets US EPA drinking water standards for bacteria and protozoa reduction.

• Meets NSF/ANSI Standard 42 for chlorine reduction, bad taste, odor.

• Meets NSF/ANSI Standard 53 for lead reduction

• Hollow fiber filter lifetime: 500 gallons (2,000 liters)

• Carbon filter lifetime: 25 gallons (100 liters)

• Filtration powered by: suction (as a straw or in-line), gravity (when paired with a gravity bag) and pressure (when used with a plastic bottle).

• Flow rate: 0.5 liters/min

• EPA Est. No. 95395-KOR-1
