Product description

The LifeStraw Flex Water Filter System is a 2-stage water filter that can be configured to be used in a variety of different ways. Similar to the award-winning LifeStraw Personal filter, the LifeStraw Flex can be used by itself as a simple straw filter to drink directly from any source of water. The LifeStraw Flex can also function as an inline filtration system with the included soft touch water bottle, as well as a hydration pack bladder or a gravity water filter system. The Flex water filter even makes it possible to turn nearly any disposable water or soda bottle into a powerful water filtration system. Simply attach the Flex onto the screw-top threads. The first stage of filtration is a hollow fiber membrane microbiological filter that filters to 0.2 microns and removes 99.999999%of waterborne bacteria and 99.999% of waterborne protozoan parasites from up to 500 gallons (2,000 liters) of water. A replaceable, activated carbon capsule serves as the 2nd stage of filtration, which improves taste, removes odor and reduces organic chemical matter (pesticides, herbicides, VOCs). LifeStraw Flex filter exceeds the NSF-42 standard for chlorine reduction and NSF 53 standard for reduction of lead and other heavy metals for up to 25 gallons (100 liters). System includes a 2-stage filter, collapsible soft touch water bottle and backwash syringe. Measures 4.7 x 1 x 1 inches and weighs 1.7 ounces. For each LifeStraw purchased, one child in a developing community receives safe drinking water for an entire school year.
