Bottom Line: The MSR MiniWorks EX filter is an exceptional value whether you're on a day hike or an expedition.

Excellent filter!
I've used a buddy's 2002 model Miniworks and my own new 2003 model Miniworks EX on multiple outings in a variety of conditions. I've also used the PUR (now Katadyn) Hiker and bought the Miniworks.Some folks think a filter is a heavy luxury, but consider that it weighs less than half a liter of water and the immediacy of filtering leaves you carrying less weight in the end. No more trying to remember which bottle got the iodine when or finding a water source and having to wait an hour to take a drink.There were a couple of important differences which led me to choose the Miniworks EX over the Hiker. First and most important, there's little point in filtering your water if you're just going to contaminate it by flinging drops of untreated water into the treated water. The Miniworks has a cover over the "clean" side which you only remove when it's time to use it and otherwise prevents cross-contamination from the hose you put into the possibly contaminated water source. Sure beats trying to keep the clean end in a ziplock baggy or somesuch.Secondly, the Miniworks will attach directly to any Nalgene wide-mouth bottle or bag including the MSR Dromedary bags. No more three-handed fumbling trying to keep your water bottle from tipping over and dumping out your hard-won water as you pump. Screw the bottle onto the bottom of the filter and off you go. Or simply pull the bitevalve off your hydration hose and plug the hose into the nipple on the bottom of the Miniworks. Pump fresh clean water into it until its full.Another important consideration is field maintainability. What will you do if the filter quits working and you're three days out? Of course you should always have a backup solution, but I'd rather field strip and fix a filter in ten minutes than spend the rest of the trip drinking iodine-water. With the clear body and easy disassembly on the Miniworks, this is an easy option if you're so inclined.


Great Little Filter
I have used this filter for a little over two months and it filters water perfectly. It even screws on to the top of nalgene bottles which gives you a huge container to store your water in so you dont spill any.


Works Great
I was really impressed with not only the quality of the product but with the quality of the service! My items were shipped fast and direct, no waiting and everything was in good and working order. A good product and a good supplier.


Great water filter
As with all MSR products so far, I am very pleased with the MiniWorks filter. I use it to filter water already treated with iodine tablets and the charcoal filter in the MiniWorks removes the taste and color. Filtering with the MiniWorks is quick and easy.


Sea kayaker's delight
I could not stop admiring this finest piece of equipment on my last sea kayaking trip off the West Coast of Vancouver Island. On the rainy night, we would leave our kayaks lying on the beach with all the hatches open (this is a good idea in a bear country anyway). In the morning, we could pump plenty of the collected fresh water with the MiniWorks out of the kayaks. The filter clogs once in a while even when pumping the clean looking water. For me, this just confirms its efficiency and usefulness.
