With more than 120,000 reviews and a 4.8-star rating, the LifeStraw ranks among Amazon's most popular outdoor products. Also, according to price tracking data, its latest $10 deal price is the lowest ever recorded.

10,000 sold on Amazon in May alone, proving that its popularity matches its quality. To use it, simply dip the straw in a stream or other freshwater source and drink — that's it.

Reviewers said the LifeStraw is especially useful when traveling to areas where tap water may not be safe to drink. One shopper who used it overseas said it was particularly useful when they had no access to water during a trip. "It really came in handy for me when I arrived late at night and couldn't purchase water, but I was dying of thirst," the reviewer wrote.

A single LifeStraw filters 1,000 gallons of water, giving you an affordable, long-lasting device. You can also grab two-, three- and four-packs to share with friends or stock up for yourself.

Also, since it was originally designed to help those in less developed countries, every purchase gives a schoolchild in need safe drinking water for a year. So, you get to make a difference for just $10.

One reviewer, who generally had a positive experience with the LifeStraw, noted one minor setback: "If you need to filter large quantities (for your family campsite, for cooking, etc.), this is not what you need." Instead, the shopper recommends investing in a gravity filter or iodine tablets.

With Prime Day ending in just a few hours, now is the best time to get the LifeStraw at its cheapest.
