The LifeStraw Go Series Stainless Steel 18 oz is a rigorously tested, insulated water filter bottle designed for everyday hydration, travel, and adventure. With a slim, ergonomic build, it fits most cupholders and backpack sleeves. Its two-stage filtration system combines a membrane microfilter (lasting up to 1,000 gallons/4,000 liters) that removes bacteria (including E. coli and Salmonella), parasites, and microplastics, with an activated carbon filter (lasting up to 26 gallons/100 liters) that reduces chlorine, odors, and organic chemical matter for better taste. Constructed from BPA-free stainless steel and available in multiple colors, the bottle is independently lab-tested to meet NSF 42 and US EPA/NSF P231 standards.
Every purchase supports LifeStraw’s Give Back program, providing a child in need with a year of safe drinking water. Customers consistently praise the bottle for its filtration effectiveness, taste, and durability, while also offering constructive feedback for future design improvements. LifeStraw’s transparent, science-backed approach and embedded social impact distinguish it in the water filtration market.

"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 am quite satisfied with this water bottle. It works as expected, feels high quality, and is easy to use and clean. The water tastes great from it as well. Will recommend"
"Kids love the product, its not that hard to get water from the straw!!!! The kids love it!!! Dont believe the hype on how hard it is to get water out from it, like i said the kids love it and tap water never tasted sooo great!!!"
"Love this and the fact it’s filtered! It’s a good size bottle and fits in cup holders well. But three things I’m not the biggest fan of: since the filter is so large, it’s less than 24oz since you can’t drink anything after it’s lower than the bottom of the filter. Second thing is the cap and handle. I love that you can take the nozzle you drink from off for cleaning but if you’re holding the bottle from the handle, it loosens and has actually detached while I was holding it. It would be so much better if the lid was separate from the handle! Third thing is the water pressure. I have the lid closed while it sits overnight and in the morning, most times when I take off the lid water comes spewing out and I have to drink it fast to prevent it from spilling everywhere. Maybe make a lid with a small hole for the pressure to be released while it’s sitting out? But overall I love this and use it at the gym and anytime I travel!"
"Solid water bottle that fits in my car cup holder. Due to the size of the filter displacing the water there is less water in the bottle than I initially thought. I will probably eventually get a bigger lifestraw bottle."
"Love the durability (and have dropped it pretty often, with only a dent and a few scratches as evidence), and the handle made it easy to carry around. I'm trying to reduce my PFA and microplastic consumption, since I saw on the news that "forever chemicals" can be found in our waterways here in Canada, and using a lifestraw product to filter my water gives me a bit of peace of mind in that sense. Unfortunately I lost mine recently at the dog park, and have had no luck getting it back. After 3 months of using glass bottles, I eventually caved and am now repurchasing (yay!). Mostly for convenience sake as being crunchy is both a privilege and a whole lotta work. LOVE MY LIFESTRAW WATERBOTTLE THO!!! 😭💗‼️"
"I bought the Go Series bottles for myself and two of my teenage children to use during a mission trip to the Dominican Republic. I was honestly afraid to trust it at first, but when bottled water ran short, I filled my bottle in a bathroom sink and had to trust it to do its job. I used it 4 more days from various taps without any issues. We drink a lot of water, so it was a lifesaver to be able to have accessible clean water no matter where we were."
"As someone who is a student always I would be remised if I did not offer some opportunity for improvement. That being said, I would like to provide my thought on improving the lid of this product. It could be made out of metal instead of plastic. And the lid for the mouth piece could also be improved to be something like the flip top covers that some other companies use. Other then that. This bottle is amazing. I am currently drinking out of it as I am writing this review. Thank you and I look forward to some type of lid / cap improvement in the future!! DRINK ON!"
"Hi! I bought the LifeStraw Go Series Stainless Steel water bottle for an upcoming trip. After having stomach problems on a previous trip, I decided I did not want to worry about stomach problems again. I love the look and weight of this water bottle. Looking forward to my upcoming vacation with No stomach issues!!"
"Perfect water bottle for me; I take it with me for all day use. Pleased with my purchase."
