For those solo trail excursion or time out on the road, you don't always want to bring a full blown water filter with you. Enter the filter in a bottle category. With no batteries, no pumping, no waiting required, the in-bottle filter is a simple and easy way to ensure safe drinking water whether recreating in the backcountry or drinking suspect tap water. Vapur recently added the MicroFilter to their new Explorer Series, giving you the option of filtration in foldable water bottle form.
The Vapur MicroFilter is a portable, lightweight, and chemical-free water filtration system that uses hollow fiber membrane technology to safely remove 99.9999% of water borne bacteria (such as Salmonella, Cholera, and E. Coli) and 99.9% of protozoan cysts (including Giardia and Cryptosporidium). Weighing just 2.7 ounces and folding up small when not in use, the MicroFilter is capable of purifying more than 500 liters of safe drinking water from lakes, rivers, streams, or straight out of the tap.
The MicroFilter itself is made out of 60 meters of multiple hollow fiber membranes packed into a compact casing with an absolute pore size of 0.2 micron. These membranes are produced by a melt spun and drawn processes from 100% polyethersulfone raw materials. The MicroFilter also uses a mechanical stop feature to prevent you from drinking anymore water when the filter has maxed out its worthwhile usage.
The Vapur MicroFilter is sold as a filter and bottle set together with the 1L Eclipse Anti-Bottle, retailing for $69.99. You can also use the filter like a drinking straw to drink straight from your water source or to squeeze filtered water into another container.
The Vapur MicroFilter joins other available in-bottle water filter products such as the CamelBak Groove, HydroFlask Revolve, and the Katadyn MyBottle.
