Reliable and easy to clean

I just used my Miniworks on a 12 day trip on the Tahoe Rim Trail and it performed with no issues. The flow is good, but not quite 1 liter per minute. I found that cleaning the cartridge about every 2 liters was necessary to keep an easy, consistent flow of water from sources that had a higher concentration of sediment. This filter is not the lightest on the market, but I've found it to be very reliable.

Works great. Used it while

Works great. Used it while backpacking to filter water from a stream and it did the job. The water tasted fresh and clean.

Confused by negative reviews of this product

Just used the MSR MiniWorks EX on the trail for 3 days having purchased it last week at a local outdoors store. I pumped 4 litres the first day with no issue, pumped 11 more litres the 2nd day, cleaned the filter not because it had slowed in performance, simply because I figured I should, pumped an additional 2 litres the following day with no issues. I truly can't understand where people are having problems, especially when they are claiming to be pumping from clear water sources... only thing I could imagine the problems I'm reading in these reviews is glacial streams with high volumes of rock flour... but again the complaints claim clear water...

MiniWorks® EX Purifier System Repair

I recently sent off my Miniworks EX Purifier System for repair. It works! My unit came back a few days ago and I gave it a whirl and works like it should have out of the box.. Thanks Cascade Designs for the rebuild.! Good customer service and good turn around time.

Unable to filter anywhere near a liter in a reasonable amount of time

Should be a straight forward filtering system. But no luck. Ran a class this last weekend to show students how to filter water using the MiniWorks. And no luck! I believe I read where the literature says it can fill a liter bottle in one minute. Wonder what's going on. Idea's anyone? Thanks!

High quality, reliable filter

Components are high quality, output is good. The scrub pad is weak, I prefer to gently scrape the ceramic with a knife.

yes

I have not yet had an opportunity to use it but seems to be very well constructed and easy to use.

I would buy again.

Found the sludgiest, slowest, frog filled water here in Northern Virginia to break it in and it delivered. I added an iodine tablet for good measure but beyond the slight iodine taste I had a liter of fine water and no ill-effects. I rest easy knowing that I'll be fine with just the purifier on any of the pacific northwestern slopes I regularly find myself on. It would be extremely helpful if platypus and MSR came together on an attachment for the platypus 1L & 2L collapsible bottles; filling mine while holding the purifier over the small opening definitely proved to be a trick.

Keep it clean

I use the mini works once or twice a year. Each time filtering no more than 10 to 12 liters. I like the fact that it adapts to most any water bottle. I use Nalgene products. It works great. The one thing I would emphasize is that you need to keep the filter clean. Take your scrub pad with you. If it starts to slow down, or gets difficult to pump, take a minute to clean it. It makes a world of difference. Also clean and dry it after each use and before storing regardless of how much it was used.
