After having used this filter on backpacking trip, I wouldn’t include this in the ultralight category. It’s also cumbersome to use, and requires continual cleaning. Having said that, it is great for camping.

Went backpacking a few weeks ago I brought an MSR pump (like this one) and my brother brought a Katadyn BeFree Water Filtration System. The Katadyn was faster, lighter, cheaper and way easier. I suspect my MSR will last longer than the Katadyn, no data on that, but if the Katadyn lasts as long as the pump I would go with a Katadyn. YMMV.

Katadyn BeFree is not a pump, it is a bag of water you squeeze through a filter. I have never used a Katadyn pump.

My son cleaned it after a trip and lost the ball check on the inlet side. I discovered this on the trail. There is a work around but it is very tedious. That is not my complaint though, I reached out to MSR to purchase a replacement ball. I received a response 2 weeks later telling me that they would just send me one for free. I was impressed, except that was 4/15/18. It's now June and after another email I still haven't got it.
I now have a Sawyer 2L system (that I got on Massdrop :) ) .
Bottom line is that if a product has little parts that are easily lost and you can't get the parts from the manufacturer I would skip it.

Only filters to .2 microns. Hold out for the MSR Guardian. It weighs 6 more ounces (22 vs 16 oz.), but filters to .02 microns, which purifies water removing all but chemical contaminants.....

Ah, dang nabbit— got excited when I thought this was some hardcore AeroPress.

I've had one of these for a lot of years, most dependable water filter out there. It's outlasted all of my friends filters and been my source of clean water on hundreds of backpacking trips. Definitely a good purchase if you're looking for one.

Love this but sadly due to shipping it's more expensive than what is found on Amazon with Prime...

Love my MiniWorks EX.
It's been absolutely bombproof for years. Regular, simple maintenance keeps it moving (just a quick scrub of the ceramic every few months or after serious silt). It's my go to for iffy water sources (everything from scum covered desert water holes to milky glacier pools) and has never failed me. It's fast enough and the weight is offset by how well it handles the toughest of water sources.
While I've started carrying the light MSR TrailShot on fast/light day hikes with clear, known water sources, any time I head into longer, questionable land the MiniWorks comes with me. Great filter.

Thanks. I was wondering about the comparison. 85 strokes per liter sounds crazy after using a Katadyn, and given that they have the same filtration rating I'll probably go with a Hiker Pro.
