Familiarity: I've put it through the wringer
I've been using the Hiker Pro for about 6-7 years now, and am so psyched these filters are still around. The filter pumps about 1L/min if you're cranking on it, and really does improve the taste of questionable water. I'd recommend this to any friend looking for a work horse water filter.
