MSR WaterWorks EX

Have used many filters and like the ability to see the filter surface (unlike my old Sweetwater), agreed it is fairly heavy but in the African bush the ability to boil the ceramic filter provides additional peace of mind.

During boil water advisory in Vancouver, Canada, the water was so poor I only got about 3L before the filter clogged and needed cleaning. Filtered for 10 days at about 15L / day and lost about 50% of the filters thickness giving an estimated 300L / filter with turbid water, not close to the claimed 1000L.

My old Sweetwater's pump handle kept breaking, so far so good with this one.

Filter replacements are MUCH MUCH too expensive, almost makes sense to buy new unit since cost of both filters is almost the same as unit new!

Four guys made the mistake of relying on one water filter for 8 days. The darn thing started clogging up after the second day. After repeated cleaning with the brush provided, the filter disintegrated by the 4th day and we had to resort to boiling water. Of course the MSR burner would also stop working by the 6th day. Luckily we had another burner from a different manufacturer to see us thru the hike. Not sure if I would ever buy another MSR product again. Anybody want a free MSR filter and burner? Slightly used and very dysfunctional.

The filter did a good job of handling lake water for 5 days. It was easy to operate since a Nalgene bottle can be screwed on the pump.

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.

The small design is great for packing in an outer pocket for ease of availability.

Excellent. It is a bit bigger and heavier than the MiniWorks, but has an extra filter for viruses. Having used both, I can say both filters are great, but for the added piece of mind I use the WaterWorks, just be sure to clean the filter out often because it really does work.

I have had this filter for 14 years. It never lets me down. Very rugged, reliable, and easy to maintain. It is relatively heavy, but I can carry 6 oz. more for a filter that is not going to break.
