The sensation that is the LifeStraw is like something out of science fiction. This deal brings the price down so low, you should scoop one up for all the outdoorsy folks you know and love—and even the dedicated homebodies. It’s that good.

In case you haven’t met this modern wonder, the LifeStraw Personal Water Filter enables you to make just about any type of water drinkable. Currently just $15 (down from $30), the LifeStraw is a great gadget to have around. It inspires adventure in all who behold it (and who couldn’t use a little inspiration right about now?). And it’s an amazing tool of survival: the Swiss Army Knife of potable water.

The straw contains a microfiltration membrane that removes 99.999999% of waterborne bacteria (including E. coli and salmonella), and 99.999% of waterborne parasites (including giardia and cryptosporidium). The filter also removes the smallest microplastics found in the environment, and reduces turbidity down to 0.2 microns.

You use this like any other straw. Simply remove the cap, place one end of the straw into water you come across in nature, and suck. The hollow fibers inside the straw trap pathogens, so the only thing that touches your lips is clean, safe, drinkable water.

This straw also lasts. The microbiological filter will provide 1,000 gallons of clean and safe drinking water, as long as you use the straw the way it was designed and maintain it. And, if you’re taking it camping, it won’t weigh down your pack: It weighs just two ounces.

Shoppers absolutely rave about the straw — it's amassed over 50,000 five-star ratings!

“I drank from the most disgusting looking crevice filled with brown scum. I thought, this is going to be safe, but taste horrid. WRONG. TASTED LIKE THE FRESHEST SPRING WATER. Better than any tap,” one person wrote. “I've used these both in Iraq and Afghanistan. Works as advertised. Extremely reliable and genuinely safe to use filtration system,” another said.

"I am going to keep this one simple," one adventurer shared. "Recently I got stranded in the back woods of the Adirondack mountains. I had ran out of water earlier on the first day and used this until I was rescued on the morning of day three. THIS WORKS. This helped save my life. If you hike YOU NEED THIS PRODUCT."

LifeStraw is also big on giving back. For every straw you purchase, a school child in need receives safe drinking water for an entire school year.
