Here's what other sites are saying:
From US Outdoor Store:
"MSR WaterWorks EXFeatures:This high-quality cartridge exceeds the EPA’s requirements for bacteria and protozoa removal. The newly designed AirSpring Accumulator reduces the effort required to pump water and increase flow. Drop one into any of MSR's pre-20"
From REI:
"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."
From RockCreek:
"The WaterWorks EX by MSR offers greater protection than any other filter in their line. Long-lasting and fully field-maintainable, it features a durable ceramic element that delivers years of protection, as well as a second-stage PES membrane for extra filtering power. The WaterWorks can be cleaned repeatedly for full recovery, with no tools required for complete disassembly. And, thanks to its innovative AirSpring Accumulator , it is capable of pumping one liter of water per minute."
From Altrec Outdoors:
"Pumping water ranks down there with washing dishes on the favorite chore lists of most backcountry enthusiasts. While we can't do anything about the discomfort of stooping over a stream or lake, the WaterWorks EX reduces your time spent on task, especially if you're supplying water to a large group or a well-equipped base camp. The WaterWorks EX features a practical device called an AirSpring Accumulator to improve your water pumping efficiency about a liter per minute--a 45% improvement compared to similarly sized filters. It works by trapping an air bubble inside the redesigned filter housing. This air bubble compresses on the down stroke to store energy then expands on the upstroke to push water further through the ceramic cartridge. Because the inside of the cartridge is under constant pressure, more water flows through in less time. That adds up to more break time during your breaks--which is a good thing at any altitude."

This is a good filter for one or two people, but is too slow for a larger group to use. The single pump action is slower than then duel pump action of other MSR pumps."

During boil water advisory in Vancouver, Canada, the water was so poor I only got about 3L before the filter clogged and needed cleaning."
