New water filter!

Expensive but looks very promising . Good catch.

Neat idea, but it's very expensive and heavy though. At $350 and 17 ounces, there are definitely cheaper and lighter options out there, and way less expensive on your immediate pocket spending. Any number of other filters along with tabs would be fine by me such as: Sawyer Mini along with Katadyn Micropur Tablets for a 30 day trip would only be $25 + $41.85 = $66.85. The Sawyer filters out: 99.99999% of all bacteria, such as salmonella, cholera and E.coli; and 99.9999% of all protozoa, such as giardia and cryptosporidium If I was still worried about bacteria and viruses, I would just add Katadyn Micropur Tabs to the system. A little more to fiddle with, but at a great weight / $$$ savings. They purify 1 liter each. Purification Time: (virus and bacteria) 15 min, (Crypto and Giardia) 30 min, (Crypto in worst-case water) 4 hour For a 30 day trip, that comes out to $66.85 total for the filter and 3 tablets a day, and a combined weight of 4.14 ounces or less (with the tabs still individually wrapped until use). I understand the hype about the cartridge not freezing, but with my internal frame packs, I've never had a problem. I just keep any filter inside a reflectix sleeve inside the pack, in the center, and near my back… No freezing problem. The heated cartridge will filter the water before it freezes. Then I put it away. When around camp, I carry it in a pocket. Your body heat will keep it from freezing. At night, I keep it in the bottom of my sleeping bag… Again, no freezing problem. I'm not even an ultra-lighter per say. At this point, I've just managed to break the ultra-light barrier. I've learned along my journey to lighten my load that there is more fiddling to be done as a result, but I personally feel that the weight savings is worth it every time.

I'm intrigued. I have been looking for a new water filter for canoeing trips. My short list so far are the First Need XLE and this, the MSR Guardian. I like in the video how they show it self cleaning in the dirty puddle water.

http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=105693 I posted about this a while back, but I'm still interested despite the $350 price and weight premium over my Sawyer Mini. During my last trip, filtering water wasn't hard to do, but it was such a slow process that it became cumbersome and tedious. Every time we stopped, I had to think about water and how long it'd take me to filter. The fact that the Guardian filters at 2.5L per minute with no back-flushing is a real deal-maker for me.
