The LifeStraw Go Series Stainless Steel 18 oz is a robust, insulated water filter bottle engineered for daily hydration, travel, and adventure. Featuring a slim, ergonomic design that fits most cupholders and backpacks, it combines a two-stage filtration system: a membrane microfilter (lasting up to 1,000 gallons/4,000 liters) that removes bacteria (including E. coli and Salmonella), parasites, and microplastics, and an activated carbon filter (lasting up to 26 gallons/100 liters) that reduces chlorine, odors, and organic chemical matter for improved taste. The bottle is made from BPA-free stainless steel, comes in a variety of colors, and is independently tested to NSF 42 and US EPA/NSF P231 standards.
Every purchase directly supports LifeStraw’s Give Back program, providing a child in need with a year of safe drinking water. Customers consistently praise the bottle’s filtration effectiveness, taste, durability, and positive social impact, while also offering constructive feedback for design enhancements. LifeStraw’s science-backed transparency and embedded impact model distinguish it from other water filtration brands.

"We purchased 8 bottles for our family of eight traveling to Kenya- the bottles are colorful-(we bought 1 of every color) They are sturdy & have kept us from getting sick. The only drawback is that it is harder for they younger children to suck the water up the straw but still Doable- so glad to have this resource availed for this kind of trip."
"We just returned from 2. 5 weeks travel in Ireland, visiting the big cities as well as the countryside. Our water bottles were invaluable everywhere we went, allowing us the opportunity for clean water wherever we filled up. One thing we found that it was tricky to take vitamins while sucking up the water. Also wished we could pour out clean water to make tea from. We relied on the water being boiled in kettle."
"I purchased 2 bottles since there are 2 of us here. They look sturdy. We'll packaged. Of course l have no idea if they will work as advertised since we have not had any emergencies in the weather or environment. I trust they will work well."
"I keep buying LifeStraw stuff. I keep recommending LifeStraw stuff. It works. Gives tremendous peace of mind at home, on the go, whilst traveling, in the car. Yeah. Get it. You will not regret it."
"It’s a really good product that eliminates the need for bottled water. I wish it had more ergonomic features, like being smaller at the base to fit better in cup holders, a locking mechanism to prevent the cap from twisting off over time, and a water bottle sling or a full silicone cover to prevent dents and paint chipping."
"I take this when I'm out with my Grandson for quick worry free water no need for multiple water bottles."
"Very well made! Easy to refill. Clean water everywhere!!! For EDC also very convenient !!!"

"This is for my go-bag. I have not used it and hopefully will never. I’ve heard good things about it."
