Best Filter system out there
I love the fact that you never have to pump. The filter is lighter then 90% of the filter on the market. The filter is 1.5 times faster then most of the filters on the market. It packs down really small. Plus no pumping. To clean all you have to do in reverse the flow to back flush. I have been using this for about 2 years and can rave enough about this product. I have been on backpacking trip with 10 people and we used this one filter only for the trip. After the trip almost everybody asked what that filter was because they wanted one. The filter does not have a carbon filter that comes with it, but this year they introduced a carbon element as an accessory.
