Been gone out of town for a week. Got home and sat down to flip through the newest REI catalog. Flipping through the section on water filters. Whoa.. what's this. A new model of MSR Mini-works filter?? The writeup on it says it now pumps 40% faster. Could it be true? Checked out the MSR website and they claim the new model of mini-works pumps a liter of water in one minute which is the same time the PUR Hiker claims. MSR also says the force needed on the mini-works has been reduced. I loved the design of this filter but hated how slow it was. Hmmm, wonder if I could send my Aqua Mira back to Campmor??
