Surprised not more hits on this?? Ordered a case shipping next week
Yeah it looks like an osmosis demonstration that my biology teacher showed me in high school.You place it in water and it absorbs it through the plastic?
We looked at these a couple years ago after they got some good press from Haiti. I think they are expensive for what they are. You are paying about $10 a pouch for 12 oz of gatorade water. A bucket of 20 is about $200 and that is about 10 liters of water. About a day or 2 for a family of four. It takes an awful long time to get a little water and they are only good for one use. Some of HTIs other products look pretty good and the technology is very cool but these are too expensive for what they are in my opinion.
This filtration pack is extremely easy and powerful. All you have to do is drop the pack in any fresh water source. Produces approximately 12 fl oz of clean water. The Hydropack produces a safe, hydrating drink using Forward Osmosis. It also provides the highest level of filtration of any personal water treatment system because it uses a system of filter holes each only 5 ten-billionths of a meter! With a filter that fine, protozoa, bacteria and viruses don’t stand a chance.The clog-free filter wall allows for full hydration of 12-16 ounces in 8-12 hours completely hands free. [[[[[[NOTE- not for use in seawater or antifreeze.<<<<<<. Wtf can't purify antifreeze fail lol
They make a reusable 10-day "pouch" that does 54oz per use. Takes 4-12 hours to filter 54oz.

Not a long term solution, but a reasonable portable solution. Also, since it's passive, you can fill it and get back on your way, letting it filter while you're moving or working on other survival tasks.
Or maybe the filtered water has a weird taste that they're trying to cover up.
