    Comments about MSR SweetWater Purifier System:

    I've taken this wonderful filtration pump (I have the older model) to Isle Royale, the Boundary Waters, South Manitou Island and North Manitou Island. It's easy to use AND easy to clean for someone who is very non-technical, and gives me great water every time. I use the anti-virus drops with it. Never had a problem. Highly recommended.

    Bottom Line Yes, I would recommend this to a friend

    Comments about MSR SweetWater Purifier System:

    I have had two of these manufactured under the Guardian label and both have broken in the field. One the stem inside broke and the other had problems with the pump handle. Filtration is great but the design puts a lot of stress on the plastic parts. For the same money a Katadyn is more durable, if not nearly as fast.

      Comments about MSR SweetWater Purifier System:

      This was the first filter I have bought and it did not disappoint. I have used this 3 times in the Red River Gorge Kentucky. Every time this filter has performed well. I was the only one with a pump my first two backpacking trips and was pumping water for 5 other people both times, 3 other people the 3rd trip. Water was clean when it came out, pumping was easy, the only problem was that sometimes I had to stop pumping in between bottles and brush the filter 3-4 times to do some minor cleaning so it would pump easier. But besides that it pumped well and I love the fact that it pumps water with both the up and down stroke! The river where i got the water from those times too wasn't a clean river either. The 3rd time the water that i pumped from was actually down stream of a place where people were bathing i found out later! But all three times everyone who used my filter did not get sick. After I got back I washed the filter thoroughly and stored it back in my pack, when i used it the 2nd time it worked just as great as the 1st, same with the 3rd time I used it. I would recommend using a coffee filter over the prefilter in the water you are pumping to help preserve the filter. The filter works very well and i would highly recommend this product to anyone, great filter for the price!

        [...]. We have taken it on several back country trips and high elevations. It has proven it's worth many times over. We ended up pumping for friends also because thier system was to complicated for them. I would strongly recommend this product!!!

          This pump has been great for me. i have used it many times. During all seasons and in some murky water sources. Just make sure you follow the instructions and this pump wont let you down. It fills a 1 liter bottle in less then a minute. if water starts to come out of your over pressure valve good chance you need to clean the filter. This is a quick and easy processes. Make sure you do this i learned the hard way and broke my pump on the 2 day of a 4 day trip. This was not due to a equipment flaw. i was over taxing my pump and not performing the proper maintenance. luckily i had another one and remembered to clean it and had no problems after that.

          Comments about MSR SweetWater Purifier System:

          I've used this system for the last couple of years, and recently relied on it completely during a weeklong summer trip to Lake Meade, where temperatures were well over 100 degrees daily and our water intake was massive. The system held up well and produced clean, clear water with no bad taste. It's actually useable while I'm still in the cockpit of my kayak, which was convenient. There are a couple of downsides, however. First, the intake tube is constantly making contact with the output tube, which could be a problem in contaminated water. There's no way to keep them seperate. Second, the end of the intake tube, which holds a pre-filter, never sits correctly or stays where you need it to in order to get a good pumping position. There's a float provided that would work great in deep water, but if you're pumping from the edge of a stream or a beach (freshwater, of course) it's constantly moving towards you and into silty water. In order to really get away from heavily silted or muddy water, you need to get knee deep in the water so that the float can be adjusted to keep the pre-filter above the mud or silt. The filter, like any micropore filter, clogs quickly because of this, although with a quick brushing with the provided cleaning tools, you can be up and running even with a filter that is towards the end of the useful life.

          Bottom Line Yes, I would recommend this to a friend

            Comments about MSR SweetWater Purifier System:

            I used this on day hiking and backpacking trips, especially to Colchuck and Yosemite. Very light, easy to use, and simple and easy to pump. I have the original Sweetwater system before it was part of MSR, and it's working like a charm. Never broked on me (as other have mentioned). One thing I like about this filter is that I have those Camelback filter attachments, because I have had too many instances where I needed water, and I didn't want to take out the bladder. I can just change the bite connector, attach it to the end of the filter, and just pump cold, refreshing, filtered water.

            Bottom Line Yes, I would recommend this to a friend

            This unit is easy to use and the water it produces is clean, clear, and odor free. It does take a bit of energy and time to get the water pumped through, but the end result is worth it. The pump is fairly compact when it's stowed, although the tubes tend to get in the way a bit. I use the drops, but they expire rather quickly, especially if you don't keep them refrigerated. Cleaning is easy.

              An old classic, the SweetWater has been around forever. It's not the fastest filter out there, but it filters really well, quickly, and with minimal effort. The design allows it to filter on both the up and down stroke, making things go by a lot more quickly. The pre-filter/silt-filter is great for keeping the SweetWater from getting clogged, too.

              The filter is fast with its double action pump. Thought about sticking with iodine or buying a battery powered purifier, but with the filter, I don't have to worry about time or taste. The only down side is that it gets clogged up at times and needs field cleaning.
