Rated 5 out of 5 by from Most bombproof Pump On the Market This pump may not be the lightest, but it is reliable and can filter more water than you will ever need on one trip. The entire assembly can easily be taken apart and checked out in the field and cleaned. It also stows well with the hose wrapped around the pump and secured to the end of the handle. In about 5 minutes of easy pumping you can have yourself clean crisp drinking water. The best part is that it can be filtered directly into a nalgene or a dromedary bag to make the process even easier. Use a coffee filter rubber banded to the end to filter out the first layer of dirty water to further extend the life of this filter.

Rated 4 out of 5 by from Long lasting, Easy to service. I have had this filter for 4 years now and it is still my go-to filter. I also have a katadyn hiker pro but prefer the MSR hands down. From day one this filter was easy to setup, easy to use, and easy to clean. After every trip I tear it down, clean it up, let it dry, then put it back in a box till the next time I need it. It attaches securely to all my water bottles as well. The long handle gives great leveraged to get water fast. Overall, I am very happy with my purchase.

Rated 4 out of 5 by from Survived on water pumped through this for a week. In combination with tablets, this filter did exactly as advertised and provided myself and a companion with clean drinking water from a scuzzy, boggy lake. We pumped 2 liters at a time and then treated the whole bladder with the MSR tablets to add another layer of protection and it seemed to work like a charm. No trip-ending diarrhea or other illnesses and we went through many, many liters of lake water from different spots. It goes a little slow, but with two people (one to submerge the end so it doesn't drag on the bottom and one to pump into the bladder) it was over in about 5 minutes per round. Easy to clean and better than a sock.

Rated 4 out of 5 by from Miniworks mighty awesome! This year makes the third year that the mini works has been in my backpack. I have tried other filters before and during use of the miniworks and I always go back to it. My two favorite things about this filter: 1.I never worry about the taste of my water, the charcoal filter makes it taste clean every time. 2. I never worry about the quality of the water i am drinking after filtering. I know the water i am drinking not only is safe but tastes amazing. My only complaints if i had to pick any are: 1. The unit can be a little big in the backpack but its worth giving up the room for safe water. 2. It can be slow to pump sometimes, but thats a trade off im willing to take for safe water going through a ceramic filter. If you are thinking about getting this filter i highly recommend it.

Rated 5 out of 5 by from Awesome Filter Had this filter for a couple years and have taken it on several outings with no issues. It is very robust and easy to use/clean. My only complaint is the amount of pumps/time it takes to fill up your container though it is not a huge deal. I never write reviews but was motivated after getting off the phone with customer service. I called after I dropped a small part down the sink while cleaning my filter. They took my info and told me they would send the part free of charge. Would highly recommend.

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from It has its ups and downs The pump is easy to clean and maintain which is a plus. Its also nice for times when there is very little water to get at and beats out the gravity bags in those cases.,,,,I have had some issues recently with this pump where the chamber doesn't fill all the way or fast enough to keep up with the recommended pumping rate, which is kind of a pain. Attaching a nalgene to the bottom for filling up is recommended, as it will make life much easier for you, other wise you might need your buddy to hold your bladder while you pump. I wouldn't mind having an accessory for connecting to bladders with a larger opening to eliminate the need of carrying a nalgene.

Rated 5 out of 5 by from a tough field dependable water filter we had the chance to canoe algonquin park , not to long ago. for water purifications. you have 3 choices. boil it to death/chemical treatment or filtering. we were under a fire ban ,so that left us with 2 choices and we went with the msr miniworks. these are very large wind churning lakes, where there is constant silt and sediment. that will clog up any water filter very quickly. with the supplied scrubber we quickly remedied any slow to pump water. then would rinse the ceramic with the last of the remaining clean drinking water. over several days it came back to life, with in minutes. we are very pleased customers.

Reviews show ups and downs. Has there been any type of redesign on this product lately ? Or is it operator era ? I would like to purchase one, but reviews leave me wondering. Thanks

Asked by: Brad
Brad, There has not been a redesign on the MSR Miniworks EX Microfilter. I took a moment to read through the reviews and, Im not seeing a consistent issue. The thing in the reviews that is consistent is praise. I have seen the MSR Miniworks EX Microfilter filter water, and it worked wonderfully. I hope that this helps. Happy Trails.

what is the purpose of the red crescent shaped piece from the picture?

Asked by: curious george
Hey there, The red crescent pictured for this item is a gauge that is used to measure the erosion of the ceramic element of the filter during routine cleaning and maintenance.
