Product description

The LifeStraw Universal Water Filter Bottle Adapter Kit is the first bottle adapter kit with a 2-stage filter. Two different sized caps make it possible to turn almost any water bottle into a powerful water filtration system, for cycling, hiking, fitness, travel, and emergency preparedness. The kit includes a replaceable 2-stage filter, wide cap, standard cap, interchangeable standard and sport mouthpieces, leakproof lid with easy-carry loop, and kit bag. The first stage of filtration features a replaceable hollow fiber membrane microbiological filter which filters to 0.2 microns, and removes 99.999999 percent of waterborne bacteria, and 99.999 percent of waterborne protozoan parasites, from up to 1,000 gallons (4,000 liters) of water. The second stage of filtration puts water through a replaceable activated carbon capsule, which reduces organic chemical matter (pesticides, herbicides, VOCs), exceeds the NSF-42 standard for chlorine reduction, and improves taste for up to 26 gallons (100 liters) of water. All kit materials are FDA approved, and manufactured from food grade silicone. Kit components are compatible with most popular water bottle brands, including several styles of Nalgene, Hydroflask, Camelback, and Klean Kanteen bottles (sold separately); may fit additional bottles with compatible mouth diameter, threading, and a minimum bottle height of 7.3 inches. Filter, one cap, and lid weigh 3.3 ounces, plus the weight of the bottle. The LifeStraw Universal Water Filter Bottle Adapter Kit makes it easy to filter, using almost any bottle to scoop water from a lake, river, or other contaminated outdoor or urban source, so that clean, safe water is accessible anytime, anywhere. For each LifeStraw purchased, one child in a developing community receives safe drinking water for an entire school year.
