LifeStraw Flex with Gravity Bag Filter

A versatile option for camping, backpacking, or emergency use, the LifeStraw Flex with Gravity Bag utilizes a hollow-fiber microfilter and a modular design to effectively produce a gallon of safe drinking water at a time or work as a lightweight, portable filter to be used with other water bottles (bottles not included).

Filtration occurs in two stages. A 0.2 micron microfilter is 99.9999% effective against waterborne bacteria, protozoa, giardia, and cryptosporidium. A Carbon + Ion exchange filter protects against heavy metals and chlorine while also reducing odor and improving taste. No pumping is necessary, and no iodine or chemicals are utilized. Simply fill the included BPA-free 1 gallon roll-top reservoir, hang it up, and allow gravity to run water through the 27" hose and 2-stage filter. The hose and filter can be detached from the bag for cleaning or backflushing and the filter can be used on its own or with another bottle when you don't need to filter a full gallon. Back flushing is simple, and a small syringe and user manual are included.

Reflecting a dedication to providing the world with safe drinking water, for every purchase made, LifeStraw gives back to water purification efforts in developing countries.
