The sensation that is the LifeStraw Go Water Filter Bottle is like something out of science fiction. In case you haven’t met this modern wonder, the bottle enables you to make just about any type of water drinkable. Yes, we’re talking pond water, river water, lake water and more. The activated-carbon filter in this clever gadget removes bacteria and protozoa — and turns iffy water safe and clean.
Right now, the LifeStraw Go Two-Stage Water Filter Bottle is on sale for just $30, or $20 at Amazon. This is a nearly 40 percent savings and the lowest price on the internet for this super popular water bottle! In fact, it's so popular that it has earned a perfect five-star rating from more than 8,300 reviewers.
And if you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more.)
How it works
Normally priced at $50, the straw inside of the 22-ounce BPA-free LifeStraw Go Water Filter Bottle contains a microfiltration membrane that removes 99.999999 percent of waterborne bacteria (including E. coli and salmonella), and 99.999 percent of waterborne parasites. The double-layered filters also remove the smallest microplastics found in our water sources. It also weighs less than eight ounces, so it won’t weigh down your pack. And shoppers love it for making their water cleaner.
"I really like the fact that you can filter any water on the go, theres no real set up, just pour the water in and drink through the built in straw," noted a savvy shopper. "Simple, you can take that nasty tap water from the sink if you have bad pipes or the city water is subpar and then have clean and good tasting water..."
Easy to use in the wild
How do you use it? You just remove the cap, dunk the water bottle in a stream, pond or waterfall, place the straw end back into the bottle and sip. The hollow fibers inside the straw trap pathogens, so the only thing that touches your lips is clean, safe, drinkable water. Amazing.
“....My daughter and I challenged ourselves the first year of owning a LifeStraw to drink from every natural body of water we came across,” shared a satisfied Amazon shopper. “We have drank from springs, rivers, creeks, ponds, lakes, reservoirs. I was even brave enough to test it on creek water that ran through a cow pasture (don't judge, it was the only water for five miles). I never got sick from any of the water I drank through this straw. Now, either I have a killer immune system or this thing really works....”
The microbiological filter has staying power. As long as the LifeStraw Go Water Filter Bottle is used and maintained according to instructions, it will provide 1,000 gallons of clean, safe drinking water. And the company is big on giving back; for every LifeStraw Go Water Filter Bottle you buy too, LifeStraw provides a year of safe drinking water for a child in need.
At $30 (was $50), the LifeStraw Go Two-Stage Water Filter Bottle is ideal for hiking, camping and even road-tripping — just about any outdoor activity that gets you out of the house.
Even trips abroad, "This water bottle is amazing — a must have for travel! I purchased it before a trip to Havana and could not have been happier with it," raved a delighted five-star reviewer. "I filled it from all kinds of taps in Cuba (public restrooms, hoses, kitchen sinks) and didn't have any health issues — it definitely makes the water safe to drink! It was so much easier and way less wasteful than having to find bottled water everywhere. The filter won't improve taste at all, so don't expect pure-tasting spring water, but it will keep you from getting sick."
