MSR WaterWorks EX Filter - '07 Closeout

The double-filtering MSR WaterWorks features new EX technology which utilizes back pressure to improve the water flow rate. New venturi/dampening device also offers the added benefit of reducing the force required at each pump stroke. Ceramic element provides reliable, long-lasting performance; activated carbon core adsorbs chemicals and foul tastes. Ceramic/carbon media can be cleaned over and over for maximum field life. Second-stage 0.2-micron PES Membrane Cartridge supplies extra filtering power and unequaled bacteria-removal capability. Threaded pump easily attaches directly to an MSR Dromedary™ bag or a Nalgene® wide-mouth bottle (sold separately). Durable, chemical-free filter is easy to use and field maintainable. For the ultimate in protection, treat water with iodine, then filter—MSR's activated carbon core will remove the iodine and its unpleasant taste. Includes stuff sack and cleaning pad. Closeout.
