This survival water filtration system is AWESOME! You can get it here on Amazon.
When you are an avid outdoorsman, and like to spend time camping or hiking long distances, it is a struggle to lug enough water to properly hydrate yourself, especially in the hot summers. So that is where this little device comes in. It is super easy to use, and very efficient.
The filter in this straw is good for up to 396 gallons of purified water, and can filter 450mL per minute. It uses an activated carbon filtration system.
I love being prepared. Just the knowledge that I am ready to face any emergency, makes me feel more at peace.
