Water purification.

[LabRat]

From what I have read, at about 6 months under low temp and light it will slowly begin to breakdown. It will still work as it breaks down but it will require more for purification. Since smell is considered a factor during the purification process, it can still be used.

Anyone have one of the Bubi bottles? I'm ordering one tonight to test out.

Silicone bottle able to be put in a fire and boil water is a good feature. A little pricey but I think it's worth it if it works.

I just ordered a Platypus GravityWorks yesteday....Ill report back when I get a chance to use it.

This has been around a while apparently, but I heard about this the other day and thought it was a sweet idea.

18,000 Liter filtration life, and super cheap. That's 4755 gallons of clean drinking water for 25 USD.

FYI, you can boil water in any plastic soda bottle. Just in case you didn't know.

I saw an ad for the lifestraw too. Anyone have any experience with it?

No but I'd really like to look into that Lifestraw Family. Uses a bladder to pull water from a hopper through the straw/filter. Seems that would be more practical than just a straw in your pocket.

 

[Crippler7815]

you could use it for cooking and such that way, but I imagine it wouldn't be hard to start a syphon through the lifestraw and some tubing to fill up a gallon jug/water bottle/cooking pot.

Yeah, the actual straw would just be good for backpacking/SHTFandgetthe****inthewoods

You're going to have to explain this one to me. Last time I dropped a PET bottle in a camp fire, it melted.

 

[Crippler7815]

Same reason you can boil water in a paper cup, the liquid inside moderates the temp of the surface in contact with the heat. It'll burn or melt if its not a water wetted area, but it'll do. We used to boil eggs in Dixie cups for breakfast on camping trips.

So you're telling me that I can put a 2L bottle of water in a camp fire and it won't melt?

 

[Crippler7815]

If the plastic is capable of holding temps of 212, yup

Yes. I did this on MLK day when we went out in the woods. It is due to the specific heat capacity of water (if I remember correctly from Chemistry). The plastic will not melt until all of the water has turned to steam and left the bottle. My only idea about how this could be a bad idea is parts of the plastic getting absorbed into the boiling water, but that is probably still better for you than protists in the water...not really sure though.

The trick is to get BPA free bottles to limit harmful leeching (i.e. the new nalgene).

I don't actually have a bug out bag, but I have done a lot of long distance backpacking, where you must purify you water everyday, filling up several times a day.

If you want to go with a pump filter, then the Katadyn water filter ($84.95) is one of the most reliable and tested on the market.

Personally, I like to use Aquamira water drops. You simply mix Part A with Part B based on the amount of water you are filtering, add it to the water, shake and drink after 15 minutes. I like this option because it's lighter than a pump (crucial when backpacking), cheaper and quicker/easier.

Have you tried the Aquamira filtration straws?
I bought a couple off the NRA store website for emergency use nad helps the NRA also. They supposedly crry the lifestraws at Basspro also for $20. I think I paid $25 for 2 of the aquamira straws.
