LifeStraw Mission Water Purification System
The simplicity and high-volume of the LifeStraw Mission Water Purification System make this gravity filter excellent for the campsite or emergency/disaster situations.
The award-winning filter in the Mission purifier has no shelf life and filters up to 18,000 L (4,750 gal.) of water. By filtering down to an astonishing 0.02 microns in size, it removes 99.9999% of waterborne bacteria (including E. coli), 99.99% of protozoan cysts, and even 99.999% of viruses. It's also designed to handle turbid and muddy water by filtering out suspended particles. Simply using the power of gravity, it forces water through narrow fibers under high pressure, trapping contaminants in the fibers and allowing clean water to exit through tiny pores.
The Mission's roll-top dry bag is lightweight, compact, and easy to fill, while fill-marker windows on the bag display the water level. The durable, BPA-free bag also doesn't require electrical power, batteries, or replacement parts, and since it doesn't use chemicals, there's no after taste. The included shoulder strap makes carrying easy while also enabling the bag to be hung from a tree. All raw materials are US FDA compliant. Flow rate: 9-12 L/hour.
