LIFESTRAW FLEX WITH GRAVITY BAG

Compact, lightweight water filtration system with expanded protection and 1 gallon gravity bag

• • Next level protection against heavy metals including lead as well as bacteria, parasites, microplastics, and organic chemical matter like pesticides, and herbicides
  • Versatile water filter can also be used in 4 ways
  • Ultralight with high throughput, weighs only 6.94 oz (0.43 lbs), and capable of filtering 1 liter every 2 mins

How It Works

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 membrane microfilter 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

Specifications
