I got to review this collapsible 16.2 ounce water filter bag. The bag comes with a built in .1 micron water filter straw which is capable of cleaning and purifying the dirty water you scooped up.
What I like best about this kit is that you can screw the filter directly into any standard (28mm) plastic bottle.
It filters up to 300 gallons of contaminated water with a single unit. At the recommended survival amount of one gallon per person per day, this is almost a year supply of fresh water in a cheap and portable bundle.
I really liked the idea. The package was very light and compact, and the design was well thought out. I left it with my dad to do more testing, as he is living full time out on the land.
This kit is a nice idea, and it is a good price. It is not as robust as a more expensive set-up. I would not use it for day to day use. I would however use it for kits and to use to give away to friends or to barter.
For a low price water and fire is taken care of. Add in a knife and you have the basis of a cheap kit.
