We used this filter for a few canoe trips. On a long 17 day trip it quit working on day 12. Lucky for us there was another filter in the group so we used theirs for the rest of the trip. Got back and MSR said it told us it was a common problem and how to fix it but the fix was not in the instructions."

the only time i had problems is when the only water i could find was nasty pond water with a lot of slim in it. then it required me to clean it every few liters.
no problems since, actually i just boiled it to sterilize it and it looks brand new."

It removes bacteria and protozoa it but not viruses, so I treat my water with chlorine bleach in a 2 liter bag before filtering to kill the viruses."

Contains many small complex pieces and malfunctions often. Pumps slowly. My Katydan Hiker worked pretty well though."
