    MSR Sweetwater Microfilter Water Filter - Lightweight and compact, the Sweetwater Microfilter makes water filtration fast and easy. This microfilter pumps water on both up and down strokes for a fast flow rate of 1.25 liters per minute. The unique lever-action pump handle has a 4-1 mechanical advantage, so you don't have to work as hard as you pump. Weighing just 11 oz, it's one of the lightest filters on the market and the handle folds flat when not in use for easy packing and transport. The SweetWater® Microfilter eliminates over 99.9999% of all waterborne bacteria and 99.9% of common protozoan parasites, such as giardia and cryptosporidia. And you won’t believe how easy it is to maintain! A simple brushing will restore a clogged filter, and the pump lets you know when the filter needs replacing (each cartridge filters up to 200 gallons of water). When you feel the need to get away from it all be sure to bring along the SweetWater® Microfilter!

    Please note: this product can only be shipped to U.S. addresses. If you attempt to order this item and have it shipped outside the US, we will contact you and cancel the order.

    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.




    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 pre-filter 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!
