The Aquamira Frontier Water Filter is pretty impressive. It’s a water filter that weighs less than 1oz, can provide 30 gallons of fresh water and removes 99.9% of Giardia, Cryptosporidium and other pathogens. Perhaps the best part is it retails for just under $12.

Most people might think, why do I need an emergency filter? Well, it’s great lightweight insurance against dehydration. Perhaps you went out on a hike and didn’t pack enough water or left a water bottle behind. Dehydration can set in quickly, especially during the summer months. Also long as there is water nearby and you have the Frontier filter you are protected against dehydration.
