This absolutely essential survival preparedness item Miniwell includes everything you need to use their L630 water-filter as a gravity filter/filtering hydration bladder. Its unique and versatile design takes cues from the Sawyer MINI, as well as the LifeStraw Flex. Similar to those filters, the Miniwell can also be screwed directly onto a water bottle. The effective water filter has a lifespan of 500 gallons, which only manages to produce 0.6 liters per minute of filtered water. The straw is ideal for just about any outdoor activity such as hiking, backpacking, camping, travel, and emergency preparation. The straw-style filter design lets you transfer at least 1,000 liters of contaminated water into safe, pure drinking water.
