'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
The $30 water filter LifeStraw is $11 on Prime Day (Update: Expired)
A thousand gallons of clean, safe drinking water in one straw.
The LifeStraw changed the game of water filtration with an intuitive solution: You open the top and bottom of the straw, you put the straw in water, and you drink. It's an affordable, last-ditch option to filter out bacteria, parasites, or microplastics from water. You don't need electricity or a battery to power this straw -- an advanced built-in membrane blocks out waterborne parasites, including giardia and cryptosporidium, and harmful bacteria, including E. coli and salmonella -- all you have to do is suck up water.
The LifeStraw is remarkable in that it doesn't get out some or most of water's unwanted carry-ons -- it removes 99.999% of them. It also reduces silt, sand, and cloudiness in water. This could be a lifesaving tool when you're out in nature or when disaster strikes.
The filter provides 1,000 gallons (4,000 liters) of clean and safe drinking water. It's BPA free and has been tested according to protocols for water purifiers determined by national agencies like the United States Environmental Protection Agency.
One straw usually sells for $29.95, but Amazon Prime members get it for $11.12 today -- a savings of 63%.
With every purchase of a LifeStraw product, the company donates safe drinking water for an entire school year to a child in need.
