It inspires adventure in all who behold it (and who couldn’t use a little inspiration?). And it’s an amazing tool of survival: the Swiss Army Knife of potable water.

Why is it a good deal?

The LifeStraw Personal Water Filter rarely goes on sale. In fact, this is the price we've seen for it all year! That means that if you like to travel or camp, now is the time to add this handy gadget to your cart.

Why do I need this?

The straw contains a microfiltration membrane that removes 99.999999 percent of waterborne bacteria (including E. coli and salmonella), and 99.999 percent 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 the 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. It's a must-have for your next long hike or camping trip; at just two ounces, it won’t weigh down your pack. And you'll enjoy its benefits for a good long time. The microbiological filter will provide 1,000 gallons of clean and safe drinking water.

What reviewers say

Shoppers absolutely rave about the straw — it's amassed over 91,000 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. Said this shopper: “Happy with this product already as I've used them in Afghanistan when I was last deployed there”

"I am going to keep this one simple," one adventurer shared. "Recently I got stranded in the backwoods of the Adirondack mountains. I had run 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."

"It filters up to 1k liters of water which blows my mind," wrote a happy camper. "The others I was looking at could filter like up to 20gal and the price was about the same. The ONLY con about this item is it's pretty long, it's a little taller than a soda can but I'm way over this. Such a big filtration percentage, can filter a ton of water and is a reasonable size. A must-have 5/5."

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

This baby can filter up to a liter of water at a time to give you clean drinking water anywhere you go.
