I searched, but didn't see any active threads on this.
Is it worth $25? It says shelf lifer of 3 years when stored at room temperature. Does it actually expire, or is that just the same type of thing like the expiration date on bottled water? |

We bought a couple at BPS for $20 each. We couldn't find anything here, either. But they got great reviews online, FWIW.
As I understand it, s'posedly some bigger humanitarian organizations issue them to their people. Again, FWIW. We were curious if there was any local experience with them ourselves. d:^) |

I use them frr GHBs which is about all they are worth. In otherwords, you collect water in a bottle then drink the water through the straw. They are totally worthless for say making water for cooking etc. They do work.
The expiration is due to its activated charcoal and will eventually coat due to moisture penetrating the plastic. Store it say in a Mason jar with 02 abosrber, there is no reason why it should have a shelf life at all. Just remember plastic is permiable, glass or metal is not. Tj |

Single use, straw filter combo. Stick your face in the murky puddle and drink. Good for 20 gallons iirc. Posted Via AR15.Com Mobile I dunno. Sounds like a great gadget for GHB or some such "short attention span" predicament. Not a permanent solution, but better than lugging water over the countryside. That is, if the statements on the linked page are anywhere near correct. d:^) LifeStraw Specs |

| I can say with 100% confidence, they work. I always carried 1 in my patrol pack while in the sandboxes of the Middle East. Came across a lot of questionable water sources while out on lovely long range walks in the sun. I have one in all my BOB's and hunting packs. Some claim to be good for around 200 gallons. Not to sure about that claim. You can find them under $20 at outdoor shows sometimes. Good investment. |

I have no experience with this particular example, but I just posted this in another water filter thread in reference to the "filter straws:"
I had something very similar to that (a "filter straw") about 15 years or so ago when I was doing a lot of backpacking. The problem with those is that they have an incredibly low flow rate (it's hard to drink with them), and unless you drink right from the source, you end up contaminating your container as well. Better than "nothing" but not a good solution in my experience. |
