The filter is very simple to use and has a good output-per-pump ratio. You never really feel like you are doing more work than you should for the amount of water you are pushing through, especially if you take into account the fact that every pump is worth about one gulp of nasty water that you WON'T have to drink. If you do see a diminished output, simply unscrew the filter housing and give the element a light scrubbing. We were taking water from a brown lake that is loaded with tannins and we would get about 2 litres through (about 2 full-size nalgene bottles worth) before we noticed the filter could use a cleaning. Tannin-loaded water is supposedly some of the worst for clogging these ceramic filters, so if you have cleaner water sources at your site than we do, your element-cleaning cycles should be farther apart. The water came out crystal-clear and almost tasteless. It didn't taste like Dasani bottled water, but it definitely didn't taste like tea-colored lake water either. Pretty much neutral. More importantly, it tasted CLEAN and nobody got sick. Also, the MSR Miniworks requires no chemical additives but still claims to filter everything but viruses. The chance of contracting a waterborne virus from a U.S.Read more ›
1. It is lightweight (I used to have a Katadyn, which is built and weighs like a rock), so it's not going to add too much to your pack. It's heavier than chemicals or some of the UV systems, but it's not bad. It comes in a nice little mesh bag, so you can stuff it into a corner of your pack.
2. It has a 0.45µ filter, which removes 99% of bacteria, and probably 99.999% of parasites (like giardia). It does NOT remove viruses, but unless you're in a crowded city without a good sewage system, I probably wouldn't worry about it. MSR makes a filtration system that adds chlorine, but for a North American or European trip, not worth it.
3. The bottom of the device fits onto standard wide mouth Nalgene bottles and canteens. I have several 3L canteens that I can fill in 2-3 minutes. It makes it easy, reduces spillage, and just is cool.

While it doesn't remove all the bad taste of the funky water, it certainly removes harmful bacterial, cysts, and protozoa. I don't believe it's rated to remove viruses, but boiling certainly will. I've used it in clear and cloudy lakes, rivers, and streams and haven't gotten sick. Definitely worth the money.
In the hot and humid jungles of PNG it was important to stay hydrated, so I was going through 3-4 Nalgenes worth of water each day. I gave this filter a shot thinking it would pack well and be heavy duty enough to keep any contaminant at bay. Well, the filter must be heavy duty because it took about 15 minutes of constant pumping to get 1L of water from the river into my bottle. Now imagine doing that over and over, day after day. I checked the unit over and over hoping to clear up some kind of blockage, but I think that the flow rate is just that slow.
I ended up switching to a particulate filter (http://amzn.com/B002GQZDJE) and a steripen (http://amzn.com/B00BCI3QOQ) to get the job done in a fraction of the time. You'll need the filter to keep any particulates from getting in the water, and then the steripen will kill off anything microbial that remains in your h2o. It kept me healthy for a year when I was regularly drinking water from rivers and streams that were far from sanitary.
I'll take Steripen over MSR anyday!
