No Pumping, Quick and Easy

By Russell Ranked #330 - Water Filters May 19, 2009

I recently used this filter on a backpacking trip with a 6L MSR Dromedary Bag.

PROS: It performed well and I could fill my Dromedary bag all the way without having to pump. While I don't carry 6L around with me, it is nice to be able to filter enough water for 2-3 people without any work. The filtration rate was fast, about 1-1.5L/minute, but the water was of good quality. There is a sediment screen on the big bag to prevent junk from getting in the tube. It can also directly connect to wide mouth Nalgene bottles. Supposedly can filter 1,500 Liters before a filter change.

CONS: Backflushing didn't work well on mine. The filter worked fine in the field, but I tried to backflush at home to clean it out. Doesn't work in freezing temps, but most filters don't work in freezing temps. Regular maintenance is required.
