LifeStraw Flex

Next level protection: The LifeStraw® Flex is a real multi-talent and finally also available with a 3,7 liter (1 gallon) gravity bag! The compact, lightweight water filtration system provides you with expanded protection on your adventures and even removes heavy metals from water.

How it works

The LifeStraw® Flex is the next generation of the award-winning LifeStraw® personal water filter – with additional versatility and protection while still being extremely lightweight and long-lasting. The cutting-edge filter can handle a wide array of contaminants found in water across the globe. It can be used in many different ways, making it the ultimate accessory for traveling, sports and outdoor expeditions. In combination with the gravity bag, the LifeStraw® Flex is capable of filtering 1 liter every 2 mins.

The LifeStraw® Flex works with a 2-stage filtration technology: The first stage features a replaceable hollow fiber membrane microbiological filter which filters to 0.2 microns, removes 99.999999 percent of waterborne bacteria, and 99.999 percent of waterborne protozoan parasites. At the second stage, the additional activated carbon filter improves taste while reducing chlorine, and organic chemical matter such as pesticides, herbicides, and VOCs. You also enjoy expanded protection against lead and some chemicals.

The LifeStraw® Flex filters up to 2,000 liters of contaminated water without using iodine, chlorine, or other chemicals. LifeStraw® products do not require batteries, have no moving parts and use no chemicals. This displays a great and more innovative alternative to iodine tablets and bulky purifiers. The LifeStraw® technology has been independently tested and certified to meet EU directive 10/2011 and EU directive 1935/2004 regulatory standards.
