The MSR Sweetwater Purifier System is a water filter with purification system for backpacking and travel. A beautiful stream, lake or pond can look clear and clean, but you'd better filter that water before taking a gulp. This lever-action filter measures at just 2" x 7.5" and weighs only 14 ounces, but this little guy charges, filtering water at a 4-to-1 mechanical advantage. Not only does it pump water fast, but the SweetWater Purifier Solution kicks virus butt, effectively inactivating them so you can drink up without getting sick. Fill up that Nalgene and get ready to cook dinner or head back onto the trail fully hydrated to eat up more miles before finding camp.

70% of what you really want in a filter.Did this filter get the job done? Sure. Did I get sick? No. Great job right? Sort of. My issue with this product is that it required constant cleaning. Meaning after filtering under 10 liters of clear mountain spring water in the Sierra Nevadas this little guy began spitting water out. According to the instructions, this meant it required complete dismantling, a thorough scrubbing and rinsing. Okay, fine done and done. 4 liters later it's sputtering water out again. After about every 4 liters it required dismantling, scrubbing and rinsing.,, Bottom line, it worked. Just not as well as I would expect considering the price tag. I would have hated to see what would have happened if I had to filter silty water. I would have rather spent my time fishing rather than cleaning a fussy filter!

very good product!I just purchased this product to finally have my own. For the last 15+ years, my Dad and I have been using his (the original) and it has continously performed. I have not had the oppurtunity to use my new one, but based on my Dad's original one (and nothing appears to have changed) I can vouch that this is a product to count on in the backcountry. Easily field maintainable and effective product.

Don't have to carry water!I purchased this product as a gift for my husband (what's his is mine). Was getting tired from carrying so much water to the mountains. Bought this version bc I used this from a friend before. It works great and the mountain water tastes so good!

Nice system but for 1 flaw, see review.Bought this filter for multi-day hike for 2 people. It worked well for filtering 1-2 gals of water quickly. Only problem was if the seals were dry then unit wouldn't pump. You need to always have some filtered water to prime the seals.
