Rated4out of5byMarkfromGood little pumpI bought this product for my backpacking trips into wilderness areas. Having used other filtration systems before I was picky when searching for one of my own. Although a little more pricy than other pumps it is worth it. It is easy to use and perform basic maintance. All I really have to say is make use the pressure relief valve is pointed away from you when using. If the water quality is low, you may have to clean it one or two times per gallon or else you may get sprayed.

Rated4out of5bySwampfromThoroughly testedI've used the MSR Sweetwater on two 8-day kayaking trips on the Cumberland river in TN and KY. This is a big, muddy, dirty river. It's brown with silt and clay, fuzzy with growth, and cattle routinely wade into the river, along with whatever washes in during rainstorms.
The filter puts out crystal clear water, and with the recommended 5-drops/liter of chlorine, I can't taste it at all--definitely less chlorine than the tap water at home.
The Silt Stopper pre-filters are mandatory under these conditions, and can plug up after as little as 3 gallons of water if I pump straight out of the river.
I've found it best to carry a collapsible bucket and fill it with river water as soon as I make camp. Then I let it sit undisturbed overnight so as much sediment as possible settles out before pumping it through the filter.
In these conditions, it needs cleaning every 1-1/2 to 2 gallons of water. However, this is simply the nature of filtering something dirty with a small filter. The only way to avoid cleaning this often is to either have a larger filter element, or to not filter it as finely. I don't consider the second choice a viable option!

Rated1out of5byMonsieurBonfromBroke after 150 liters or so. Do not buyAfter about 3 years and 150 liters or so of mostly clear glacial stream water pumped through this filter, the pump shaft separated from the plunger while we were 14 miles up in the Olympics.
Luckily we had a SteriPen and iodine as backup.
The pump failure cannot be repaired. MSR was uninterested in seeing pictures of the pump or even discussing the failure.
Also, the bottle of chlorine that makes this a "system" ate away its own cap within 6 months of purchasing this setup and leaked bleach everywhere.
I will admit that before this pump broke it was a pretty awesome pump. Keeping the clean tube clean was always a challenge, but once you get the hang of draping everything properly it was fine.

Rated5out of5bycortexNPfromMSR SweetWater Purification SystemExtremely simple to use. Compacts well to be stored in backpack. Last purifier I had was a MSR bought about 15 years ago, I like the fact that this one has an adapter to fit your water bottle.

Rated1out of5bybackpacker11fromDo Not BuyI recieved this water filter as a gift a couple of years ago and kept trying to convince myself this was a good filter. For the first weekend trip, it worked well and I was diligent about cleaning it and trying to keep it in good condition. After that trip, it went downhill. During any aggressive pumping, the filter started to release the water through the pressure relief valve, leaving no water coming out of the outlet tube. The only way to get water through was to move the lever really slowly or to filter tap water. Mind you, this wasn't because the filter was dirty. I tried it with tap water and it would do the same thing. After that, the internal housing pump cracked and it began leaking. To top things off, by the fifth weekend backpacking trip, the bottom siphon guard was so gummed up with junk, it wouldn't pump at all and there is not way to clean that or reverse the flow out to flush the dirt shield in the field. All in all, I wouldn't trust this filter for more than a day with anything other than what comes out of the tap.

Rated5out of5byDBestfromBuilt to lastMy Sweetwater filter broke and had to get this newer model. Thing is, I did the math and realized I had my first Sweetwater filter for over 15 years. The newer model seems to perform the same way as the older version. Having 15 years experience with this filter, I can set up and break down without even thinking about it. Once you get the hang of it (suggest practicing at home before taking it into the field) you can't go wrong with it. Pumped gallon after gallon with this thing, water is always good, no sickness - what more do you want? I would highly recommend this product.
