I'm wondering where I can find some. You stick one side in water and drink from the other end. It will filter 1 liter of water a day for a year! If I remember correctly, they were relatively cheap. Anyone know?
Lots of companies have come out with these to aid in African I read. There was another besides Lifestraw that seemed to have better filtration properties but the name escapes me at the time.
Keep an eye out for stuff like Coast Guard certification and other certifications, there are a LOT of fakers out there that do little or nothing to treat the water! For several years, Colloidal silver was the big fad for a while but it's virtually worthless as a purification agent, and it IS WORTHLESS sold as a pour through (or draw through) filter since it works so slowly... http://en.wikipedia.org/wiki/Colloidal_silver
OK, rather than start a new post I dug this thread up from a while ago. I hope people don't mind. I've been to the lifestraw site and it doesn't seem you can buy them in the USA. I see them for sale in Australia? There are other straw products on the market, some look even better than this one (but very expensive in some cases), but I think this one has the best pedigree. Does anyone own one and how did you buy it?
Bump Anyone? I was checking out vids on youtube and need one more than ever! Some guy drinks cow poop. If not I guess I go with that aquastraw...
I am interested in the straw filters for emergency situations. However from what I have read on other water posts. These straws still should be used in conjunction with other water purification techniques and should not be relied upon to drink straight from a cow pond. I personally don't have experience with these straws but I would like to get more input from those of you that have. In an emergency you cant't afford to make matters worse by making yourself sick.
