Introducing the Vapur MicroFilter bottle, the first collapsible filtrated water caring system. We profiled the Vapur bottle before, and we’re very impressed by its functionality. The folks at Vapur have managed to raise the bar once again; they have developed a filtrated system that fits within their bottle, and then can be folded up just as easily. The MicroFilter uses an advanced hollow fiber membrane technology that is free of chemicals, and safely removes 99.9999% of waterborne bacteria (such as Salmonella, Cholera and E. coli); and 99.9% of protozoa (including Cryptosporidium and Giardia). Talk about one great working lite (2.7 ounces) bottle that almost does it all! Get em here.
