The LifeStraw Go Water Bottle has been up to date with 2-stage filtration to fortify the taste of your water and provide even better protection. Along with the award-winning LifeStraw hollow fiber membrane filter that eliminates bacteria and protozoa, the next-generation Go Bottle incorporates a carbon capsule that reduces bad taste, odor, chlorine and organic chemical matter. The LifeStraw Go Bottle combines these technologies into a convenient, reusable sports bottle. Take the LifeStraw Go when you go hiking, camping, or traveling to areas with poor water quality. Simply scoop water from any pond, stream or river and filter as you drink. The LifeStraw Go filters water down to 0.2 microns and has been rigorously tested to surpass EPA standards for removing E. Coli, Giardia and Cryptosporidium oocysts, and plenty of other waterborne contaminants. When the filter has reached capacity (1,000 liters / 264 gallons) it’s going to stop taking in water. The activated carbon capsule will be effective for up to 100 liters (26 gallons), or the equivalent of 3 months of continuous use. Replacement filters are to be had for sale one at a time. Made of BPA-free Tritan, the LifeStraw Go bottle is extremely durable. The food-grade silicone mouthpiece is flexible which prevents it from chipping or cracking, and is removable for simple cleaning. Use the carabiner to attach to your backpack, or store in your preparedness kit to make sure access to secure, clean drinking water in an emergency. Capacity 23 ounces.
