非常用。まだ使っていませんが、安心感あり。

Painfully slow but works well. Really good exercise in patience and enjoying the moment. I’ll keep taking it out for that reason.

I've had this thing for almost 10 years. Used it at least 100+ times on multiple occasions, and it's only needed to be rebuilt once. $27 worth of o-rings basically, but it's worth it. Not even a single fault, along with 2 different dromedary bags which neither shows any signs of use. They've been packed through hills during hunting season, camped with for a week at a time, hauled on a motorcycle and literally haven't even began to have an odor/taste and no damage/use whatsoever. Highly recommend!

Lo compre despues de usar el de una amiga.Fuimos a la Selva en Centroamerica, el agua era literalmente marron y usamos este filtro para cocinar incluso en alguna ocasion para beber.Creo que para viajes "extremos" es una buena inversion en tu salud.Es muy ligero, No pesa mucho. Asi que en montañismo quizá es mejor que llevar agua embotellada si sabes que vas a encontrar rios.La bomba es delicada hay que usarlo con cuidado.Aun no he tenido tiempo de usar el que he comprado pero es el mismo modelo que usé por lo que me atrevo a opinar.

I pumped many liters of water through this and had to replace the filter. The second was going strong before it was washed away in a flood! Even after daily use for the best part of two years the filter showed no signs of age. They are an absolute workhorse of a filter. The only problem really is that if you are filtering water which has a lot of sediment the filter gets blocked quickly and needs cleaning. However, this isn't too difficult and can be done in the field. You just need to take care not to cross-contaminate the filtered section with the dirty one. Note that you really need to scrub the filter so you actually remove a layer of the filter because this also removes the blocked pours. I highly recommend this filter. It removes everything from the water accept for viruses and even bad tastes from treated or unpleasant water sources. I used it in the wild but also in cheap hotel rooms and from tap water from gas stations etc, it never let me down and I never got sick in over three years of travel in Latin America.

This worked great and used it for my first back country hunt this year. This is also my first experience using a filtration system. I was able to fill a 5gal collapsable jug it just took awhile (30+ minutes) to fill one (we had 4-5gal jugs non-MSR brands). It screwed on to my backpack bladder (non-MSR bladder) with no problems and stayed secured while filling the bladder. We got our water form a very small creek near our camp. Someone had watered their horses near the mouth of the creek where it came out of the hill. You could see where the horses crossed creek and milled around the creek for a bit. I was concerned about contamination of water but none of us got sick, so winner winner Elk for dinner.The pump was easy to operate. The hose was long enough for me to sit on a log without being bent over to keep the hose in the water.Breaking it down to clean was easy and instruction on how to break it down were clear. I wish I would have taken pictures of the filter before I cleaned it so you all could see what it looked like, nasty.My buddy used some sort of straw filtration system that attached to small bag (can also be screwed to water bottle). He was able to fill the a 5gal jug a little faster than I filled mine. He would fill the bag, put the straw on and squeeze the water out of the bag. I do not remember what brand he had or how often he would have to replace or clean the filter.We were only out in the woods for ten days and filled 2 of the jugs one more time.

Utilizzato per un trekking in Mustang di sedici gg. Ha fatto il suo dovere ottimamente. nb: per mantenere inalterato nel tempo il flusso di 1lt al minuto, occorre periodicamente pulire il filtro

J'ai longtemps attendu et hésité avant d'acheter ce filtre et je dois dire qu'il est très bien, j'avais peur que l'élément en céramique soit très fragile, mais il a quand même survécu à un voyage en avion (bagage à main). Le produit est très simple d'utilisation et le fait que toutes les pièces soient remplaçable en cas de problème vous donne vraiment une autonomie complète. Par contre je recommande de mettre un filtre à café au bout de la sortie du tuyau car le filtre à tendance à très vite se boucher si vous pompez de l'eau stagnante. J'ai testé dans un étang près de chez moi et même si l'eau était à peut près claire j'ai mis pas mal de temps à pomper pour avoir 500ml. Il faut vraiment pomper assez longtemps pour avoir un gros volume d'eau filtrée. La maintenance est très simple, juste à vider l'eau contenue dans le tuyau en pompant "a vide" et ensuite quand vous êtes de retour chez vous nettoyer le filtre à l'eau claire avec le grattoir fourni, je vous recommande aussi d'utiliser une brosse à dent car les extrémités sont difficiles d'accès. On peut alors par contre se demander comment faire lorsque l'on est dans une situation où l'on a pas accès à de l'eau claire pour nettoyer le filtre (?) c'est un peu le défaut que je trouve à celui ci, il demande pas mal de ressources pour sa maintenance. (combustible pour chauffer l'eau et le décontaminer, + de l'eau claire..).

I researched filtration systems for almost a month before settling on the MSR miniworks. I figured I could just go pick one up at the local Cabela's or REI, but BOTH retail stores were sold out of these, while there was still a good supply of the other MSR and Katadyn filter systems on the shelf. I took this as a sign that this is the filter to have and ordered it from Amazon, and it has been worth every penny. Read on....In Camp: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. lake or stream (think Polio, Hep-A, SARS, and a few others which you have probably had vaccinations for) is far lower than getting sick from bacteria or parasites. If this still bothers you, you can still boil your clear, clean-tasting water just to be sure.Out of Camp:The maintenance on this filter is very simple. The unit breaks down into 4 major parts, and the wrist pins on the pump assembly are quick-release squeeze-and-push types. You can literally have this thing stripped down and cleaned completely in about 5 minutes, and that includes the sterilization of the filter element. A couple dabs of silicone grease or chap stick is all you need to lube it up when you are reassembling the unit.The Hidden Bonus:$80 may seem like a lot for a water filter, but the MSR miniworks pays you back exponentially...Prior to buying a filtration system, everyone in our backpacking party hauled their own water needed for the entire trip. We would calculate what we needed for hydration and cooking each day, plus a bit more just in case, and we strictly stuck to these rations. We would have enough water, but never enough to truly quench one's thirst. Having this filter in our party allowed us to drop about 15 lbs carried, per person! Plus, we didn't have to pack out a bunch of empty water bottles anymore. One filter supports 4 of us and we now drink as much as we want. When you think about how important hydration is to your body's systems (Read Cody Lundin's "98.6 Degrees" book and you will know more about the subject than you ever wanted to), shelling out $80 to have clean, safe water on-demand anywhere you can find a water source is a small price to pay.Tips:-Put a coffee filter over the hose inlet and secure it with a twist-tie, rubber band, or fishing line. This will make your MSR filter pump more efficiently for longer without as-frequent element cleaning. Everytime you clean the element, you are scrubbing away some of the element's overall diameter. When it gets too thin, you have to get a new element. Fewer cleaning cycles = prolonged filter life and more money remains in your pocket. Filter element, $40. Coffee filter, 3 to 4 cents.-Bring a spare filter element if you are going on an extended trip or are going to be absolutely dependent on this filter for your drinking water while you are out! Meaning: hiking back to your vehicle and driving like a madman to the nearest 7-11 for a drink before you go into a coma from dehydration is not going to be an option! The word is, these ceramic elements are fragile. Finding this out at the wrong time and being caught without a spare would be a very bad thing. If you spent the cash for the filter and other people in your party use it, have them pony up the $40 and buy the spare element for you. It's only fair.... right?-USE A NALGENE BOTTLE WITH THIS UNIT (or other similar one that will attach to the adapter). The motion created while you are pumping is far too violent for precision-aiming the output stream into any loose container, except for a bucket. You can also attach another length of rubber hose to the outlet and run that to your container, but we have not tried this yet. The Nalgene bottle seemed like the simple solution to use with the filter and we filled our other containters from this bottle.{Product use update} - Our party of 3 did a 4-day backcountry hike in the Grand Canyon (search: Tanner Trail) this past winter. This is definitely NOT a tourist trail, and the first 2000-3000 ft of elevation is not much a trail at all. The noted only water source along this entire route is at the very bottom of the canyon, the Colorado River. We were able to augment our hike-in water supply by searching for pools of water trapped in depressions of the rocks near the places where we made camp, and pumping water from them using the MSR Miniworks. I don't even want to think of what was in those water pools, but what came through the filter was clean and refreshing. We made notes of the larger water pools, which allowed us to lighten our water load on the hike-out and stop by the pools for a top-off when we needed it.
