Nearly all of America's lakes, streams and other waterways are dangerously polluted, and even so-called "clean" public water supplies are laden with pharmaceuticals, heavy metals, industrial chemicals and traces of countless other toxins. That's why you don't have to be an outdoorsman, prepper or survivalist to benefit from a personal water purification system, and the compact, easy to use Pocket Water Purifier from 12 Survivors is one of the most effective yet affordable options available. Never walk out your front door without it! It couldn't be more convenient, thanks to the Pocket Water Purifier’s discreet 1 1/5" x 6 1/2" dimensions and straightforward straw design. Just place it in a water source - a glass of tap water, lake, stream or even a muddy rain puddle - and suck, just as you would with an ordinary beverage straw. It also threads onto a standard soda or water bottle, keeping your hands and face from contacting potentially dangerous water. With the Pocket Water Purifier, there's no need to wait for water purification tablets to ruin your water’s taste, and you don't have to lug around multiple space-hogging containers required for traditional pour-through filtration. The Pocket Water Purifier delivers pure, delicious, thirst quenching pure water at 0.4 liters per minute, and it’s made of an advanced BPS-free ABS polymer. It reduces bacteria by 99.9999 percent, confirmed by independent third party tests. With filtration down to just .03 microns for up to 1,500 liters, this lightweight, portable powerhouse prevents serious, often deadly illnesses such as salmonella, giardia, cholera, diarrhea and more. Without the Pocket Water Purifier, it’s just a matter of time before you fall victim to these waterborne pathogens, spread readily and rapidly - especially in calamitous times when water treatment systems are offline and hygiene takes a backseat to survival. But even while the grid is online, it's smart to purify every drop of water you consume. Whether you’re on a morning hike, spending a week in the mountains, clawing your way out of a survival situation or just enjoying a glass of tap water, stay safe with 12 Survivors' Pocket Water Purifier! Includes prefilter and cotton replacements.
