« Item   Item » Sawyer Water Filter Bottle, 30 oz. 34 fl. oz. polycarbonate bottle holds 30 fl. oz. of water with filter inserted. Filter adds no chemicals or chemical taste to water; accepts most drinks made from powdered mixes. Put water from any fresh source in bottle and sip through the food-grade flexible straw; water passes through an internal filter before you drink it. Single filter provides more than 500 gallons of water filtration; backwash to remove precapacity clogging caused by turbid water. Special cap rotates shut when not in use; this hides the straw and keeps it clean until the next time it's needed. Submicron Hollow Fiber Membrane uses a cluster of micro-fibrous tubes. This handy sip bottle uses a Sawyer® filter inside to provide bacteria- and protozoa-free water quickly and easily from any fresh water source! Thus, users find negligible resistance when drawing water through the straw until near the end of the filter's cycle. Using advanced technology found in medical dialysis equipment, the filter removes bacteria, protozoa such as giardia and cryptosporidium, and cysts. When water is drawn through the sidewalls of the tubes, it does so without any noticeable pressure drop. More info + price
