I was suggested this filter from a friend who had his for more then 10 years without issue. My first experience with mine was a true test of its dependability and ability to field clean. Backpacking with a friend who has a paper based filter by the competition, we quickly learned the value of being able to field clean a ceramic filter versus a useless clogged paper filter. We successfully filtered some NASTY, muddy water with my MSR and packed his away. Although filtering was slower and cleaning was required, we were able to cook with and drink clean water. My wife even took it to Cambodia on a mission trip as a backup, and it worked flawlessly! My only complaint is the speed at which it filters. Just remember, slow and steady wins the race. I would definitely recommend to a friend!
"My Favorite Water Filter for the Backcountry"
I have used this filter all over the west and east alike. I love the fact that it hooks right up to a nalgene bottle or a dromedary bag, which makes not spilling while pumping very nice. The ability to clean the filter every so often is also a bonus, and you will always notice an improvement in filtration speed when you do clean it. It is also entire ably field serviceable, and doesn't take an engineer to see how everything works. I have planned on purchasing a second for use when traveling with multiple people, but so far we have managed to get by with the one I already have.
I've used my miniworks for many years. I haven't had to change the filter yet.Try to use the cleanest water source possible.If the water is cloudy, I use an after-market pre-filter made just for this type of filter.If you don't have one of those, you can rubber-band a coffee filter or even a bandana around the intake, making your ceramic filter element last much longer between cleanings.I take my time pumping water (I am not going for world-record water flow/output).I easily get 1L of water every 2 minutes.To clean the ceramic filter, unscrew the top, take the filter out & scrub it lightly with a brillo pad or even gently with the backside of a knife blade, etc. (basically, you just want to scrape the top later of clogged ceramic off).Put it back in and you are good to go.It won't filter tiny viruses (rare), so use Steripen/chlorine/Iodine/boil after you filter if you are scared:). It will filter crypto, giardia, remove bad tastes & some chemicals from the water.I trust this filter!
Snagged this guy with some MJ Reward points and I have been using this guy for six months now and what can I say . . . this little pump really sucks . . . the water! Quick setup and super easy to use and it screws onto a standard Nalgene bottle opening for easier handling. If your water is clear, you can expect to pump at the suggested 1L per minuet, but the dirtier your filter gets, the slower the process takes. Easy to take apart, clean, and maintenance, this is my new go to filter for all of my adventures! Thanks MJ!
I did a hefty amount of research before purchasing a water filtration system. This filter has proven to be reliable and well-made. I was somewhat skeptical about the plastic handle (as pumping the water through the filter does put a fair amount of force on the handle joint) but it has been reliable without a doubt. If you're looking for a...for lack of a better term...lazy (perhaps "minimal effort?") way to filter your water, this is not the way to go. I like physical exercise and if I can throw in some more upper body exertion on my backpacking trip, then why not!?Be sure to read all of the user info there is on it, even watch some youtube videos - they're all very helpful. I recommend getting the little maintenance kit as well. Reliable, easy to clean, field-maintainable, and you get an extra work-out thrown in. Also, be sure to handle with care (i.e. don't drop it) - a broken ceramic filter is a...well...a broken ceramic filter.
"Awesome product! ...but make sure to read directions first"
I've been using the MSR Miniworks EX Microfilter for over a year now. I have to admit, the first few times I used this I ran into several problems, but that was before I read the (very useful) directions that came with it. Once I figured this thing out, it is a very simple and reliable product.Water tastes absolutely fantastic with this filter. I have never had any residue or any weird taste in the water. It also conveniently attaches to my CamelBak water bottle and MSR hydration system.Please read the directions first and clean the ceramic filter often. Water will pump MUCH faster and easier when it is used properly. From my experience, it takes 1-2 minutes per liter of water.
"Very good filter, as long as water is clear"
Very packable, small, and filters quickly. It's seamless connection to Nalgene water bottles is super-handy and prevents spills. However, when they say that cloudy/tannic water will clog it, they aren't lying! And it doesn't happen gradually; it stops this filter dead. We were doing a multi-day backpack and had 25 miles of wilderness where ALL the water was tannic (from pine bogs), which we didn't realize. Tried to let it settle as much as we could in a Nalgene (as suggested), but really, if water is that tannic, it doesn't settle out. At first, the filter worked fine, 1 liter per minute as it's supposed to, but after about five liters, it slowed to a trickle. By the time we finished the hike, it took almost an hour to do a liter -- no exaggeration. But tannic water was all we could find. What's worse, we didn't have iodine tablets as a back up. Not good. Really slowed us.If you're in an area where only tannic/cloudy water is available, this filter won't be of use.
got this for my backpacking trips. i have used it twice so far in clear rivers/creeks. it needs some pumps to fill a 32 oz bottle. but it is easy to use and the water it flitered doesnot have any bad taste. the first use though, follow instructions to fill two bottle jus to purge the filter clean. i always have it with me on my overnight hikes.
