I love my Sweetwater. I recently used it as the sole filter to support a 6 person party through Yosemite Valley, and another 4 person party through Desolation Wilderness. It's extremely light compared to the alternatives, packs relatively compactly, and most importantly, provides fresh tasting, easily pumped water. I have been careful and selective to pump from clear, fast moving water, and haven't even had it clog or need to be field serviced after pumping upwards of 60 liters over this past trip. To me, that's pretty stellar performance. I highly recommend this filter to anyone seeking a light, reliable, sturdy filter.

I'm really pleased with this filter. First, it's MSR so you know it's good quality. Second, it's light so no worries there. Third, no chance of catching the "hyperflow headaches". This really is a great filter. The water bottle adapter is a nice inclusion to the set.

I purchased this filter when it first came out & have never been disappointed. Field cleanable cartridge, fast output, & folds for easy packing. Micro strainer eliminates silt & debris. I prefer the water to sit in a lightweight, folding basin for ten minutes before pumping. This procedure helps insure longer filter life & allows me to pump in a more comfortable position.

I picked up one of these before MSR bought the company out. Pumps faster and more reliably than any other micro filter I've used. What more do you want?

I've had this filter for 9 years, works great. At first it was hard to pump and keep the clean tube in the bottle at the same time. Now I attach the clean tube right into the port of a camelback or platypus bag. The bag lays on the ground and I only have to pump, which is pretty easy with this filter. Used in the South East U.S. and I've never gotten sick.
note: I do use Polar Pure iodine if I have serious doubts about the water. Iodine tastes really bad.

Didn't want to have to deal with the issues surrounding the hyperflow so found this to be a bood compromise. The handle can be a little tricky but no big deal once you figure it out. Easy to pump and good flow volume. Used in the alpine of southeast alaska. Mild level of sediment but not much, didn't slow it down any. I'd recommend, for filtering, did not use the purification feature.

Well, more like muddy spring runoff to cool clear drinking water...in less than five minutes. With much skepticism I watched as my buddy pulled enough water out of the stream to fill three Nalgene bottles and a pot for mac n cheese before the tents were even up. Well done! Since I was the one toting it in my pack for a few days, I also appreciate the near weightlessness of this killer filter. Grabbed one for myself as soon as we got back to the world.
