Calling all outdoor enthusiasts! No, this is not a drill — the popular LifeStraw is on sale for just $12 during Amazon Prime Day this year — just in time for your next summer camping trip.

For avid hikers, campers, hunters and travelers, a LifeStraw is a necessity you need in your backpack and emergency preparedness kit. The personal water filter is a small but mighty survival tool that is designed to purify water from streams, lakes, ponds and other contaminated sources.

It features a high flow rate, zero chemicals, weighs less than 2 oz., and the straw design makes it super easy to use. All you need to do is suck on the device and when the water is forced through the hollow fibers (which contain pores less than 0.2 microns across, making it a micro-filtration device).

Then any dirt, bacteria or parasites will get trapped in the fibers, while the clean water passes through. When you’re done drinking, you simply blow air out the straw to clear the filter. You can easily down a quart of water in eight minutes using the LifeStraw.

LifeStraw removes a minimum 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan parasites, filtering to an amazing 0.2 microns and surpassing EPA standards for water filters. The LifeStraw Personal water filtration straw measures 9 x 1 x 1 inches and includes a sealed bag for storage in your backpack or survival kit.

If we haven’t quite convinced you yet, maybe the whopping 87,000+ Amazon reviews and incredible 4.8-star rating will!

“I bought this straw before traveling to Colombia, fearing a change of water might affect my stomach. I was skeptical of its efficiency in the beginning but used it with tap water and water from unreliable sources [and] it perfectly purifies the water,” said one reviewer. “There’s no odor or bad taste to the water [and my] stomach never got upset – in fact, this has been the smoothest transition in all my travels. Highly recommended.”

“I purchased several of these and gave a couple to family members who are very active, hard-core hikers. They said they work very, very well in risky conditions, and they were surprised at how easy they were to use,” said another.

Plus, the brand is helping make the world a better place, one water filter at a time. LifeStraws have been used around the world under extreme conditions for humanitarian relief, providing clean drinking water in developing communities. For each LifeStraw purchased, one child in a developing community receives safe drinking water for an entire school year.
