BreakdownThe MSR MiniWorks EX microfilter delivers long-lasting, field-maintainable water filtration in demanding hunting environments. Engineered for frequent and heavy use, it utilizes the Marathon EX carbon/ceramic element to ensure clean, reliable and taste-free water. The lightweight and compact microfilter is capable of pumping one liter of water per minute.
don't be steered astray by one review from someone who clearly doesn't know how to use this filtration system. i have had this filter for 4 years now and it's NEVER given me trouble and to mention i have never gotten sick. the water is clear, clean and smell free. i honestly trust this filter system. i will say the filter is a little bulky compared to others on the market but for me that isn't a factor. the filter screws directly to my nalgene bottle which is very convenient. muddy water can slow down clean water production but that can be said about any water filter on the market.
This was an upgrade from my original miniworks. And just like the miniworks the ex doesn’t disappoint. It’s a bit lighter and pumps a little faster.
I have one of these, though I didn't buy it here. This is a really good filter, in my opinion. But it doesn't perform all that well in very silty/muddy water. The pores in the ceramic filter get clogged and it must be cleaned with the included piece of scotchbrite. It can handle some dirt in the water, but not a whole lot. Having said that, I've found this to be a great little filter. Four stars
I’m not entirely sure what was going on in the previous review. I spent a week with mine in the Frank Church with no issues. My water was crystal clear, no smells, no off taste...honestly it was perfect. It’s not the fastest filtration system...but it ain’t the slowest either...and my water was perfect. Clean the ceramic filter every other use and it’s just as fast as any other filter. It takes 60 seconds to clean it.
Do not buy this. goHUNT should remove this product. If your lucky you can filter 1 liter per hour. I took this on a DIY backpack hunt in Alaska. Good thing my buddies had good filtration systems. Had this been my only water filtration source...I would have been in BIG trouble. WARNING DO NOT BUY!!!
