A leakproof travel water bottle that filters bacteria, microplastics, and sediment

Our verdict
The LifeStraw Go Series Filter Water Bottle is great for use in places where water quality is not reliable or is unsafe to drink without filtration. Because of its inbuilt filter system, separate water filtration is not required.
The LifeStraw Go Series Filter Water Bottle filters out bacteria (like E. coli and Salmonella) and protozoa (like Giardia and Cryptosporidium), along with microplastics and sediment, but it does not remove viruses like hepatitis A or norovirus. So, it will work for backcountry water in the U.S., Canada, and similar regions where waterborne viruses are rare. If you're traveling somewhere like South Asia, parts of Latin America, or areas recovering from natural disasters, a filter-only bottle like this one isn't enough on its own.
We tested it for three months across different travel situations like airport refills, water fountains in public places, remote fishing trips, backpacking, and daypack carry. We tested it in a fast-flowing stream and were comfortable drinking the water since the headwaters were in Oregon.
There is no press mechanism or button because the membrane filter is activated when you use the straw to drink water. It is compact enough for a backpack side pocket or can be clipped to a carabiner to hang from the straps of a cross-body bag using the rigid loop on the top of the bottle. The leakproof mouthpiece also handles being tossed around in a bag without worrying about spills.
LifeStraw Go Series Travel Water Bottle
The only real drawback is that the suction straw takes more effort than a standard straw and getting water involves the additional step of unscrewing the entire lid to get to the straw.The membrane needs to be replaced after 1,000 gallons, or ~2 months of regular use, but it is better than most other filters, which last between 30 to 60 gallons.
This is a great bottle to use in places where you are unsure about the water quality or want additional filtration.

Best for
Carry-on travel
Daily use in places with uncertain water quality
Frequent travelers who want safe drinking water
Outdoor adventures with easy access to natural water sources that need filtration
What we liked
Easy fill-up with the wide opening on the bottle
Simple filtration process activated when you drink from the sip mouthpiece
Intuitive and easy to figure out
What could be better
You need to unscrew the bottle top to access the straw, and while this keeps germs away from the straw, it isn't a one-handed mechanism to get water quickly
The bottle handle is not flexible, so it is not easy to clip to a bag with a small carabiner
How we tested
We tested the LifeStraw Go Series Filter over three months at airport terminals, on flights, on full days traveling and exploring cities, and on fishing trips.
We tested how easily it refills from hotel sinks, traditional water fountains, and from natural sources, like mountain streams in Oregon. We also tested the fit in car cup holders and in a drift boat without any issues and in the side pocket of the Eagle Creek Packable Backpack. After each trip, we tested how easy it was to take apart, clean thoroughly, and pack away for the next adventure.
We also tested it alongside other travel water bottles, hiking water bottles, and water filters and purifiers to compare features, like how easily it travels, how intuitive it is to use, and the flow rate.
Performance in the field
Packability
The LifeStraw Go Series Filter bottle fits inside carry-on luggage, a standard cup holder in a Toyota Highlander and Honda Minivan, and the side pocket of the Eagle Creek Packable Backpack and Fjallraven Kajka X-Latt 45 L backpack. We used it in a variety of packing scenarios, like in a backpack,as a handheld while traveling on a plane, and during a fishing trip.
Leakproofness
The bottle is leakproof when placed horizontally in a bag and upside down in the side pocket or a backpack. To test leakproofness, we placed it upside down in a backpack and didn’t have any water mishaps.
Ease of filling and drinking
The LifeStraw Go Series Filter Bottle has a wide-mouth opening so it is easy to fill in water fountains and sinks, which we tested multiple times on a trip. It is not chug-able because the membrane and filter are activated when using the sip mouthpiece to drink water. This bottle does not have a straw.
Portability and carry
At full capacity, the bottle weighs 22 oz and can be comfortably carried all day. We also tested the fit by placing it in the side pocket of multiple backpacks and standard cup holders in a Chevy Malibu rental car without any issues. It was also easy to carry and use in a drift boat on a fishing trip as it fit comfortably in the boat’s cup holder.
Durability
This Lifestraw bottle is made of BPA-free plastic and is sturdy enough for outdoor adventures. We also didn't see any dents, scratches, or lid parts breaking when packed in suitcases and carry-on luggage. The filter lasts up to 2 months of continuous use or 1,000 gallons. We filled and filtered water more than 12 times during our testing and didn’t notice any wear and tear. We also dropped the bottle on a concrete sidewalk and it did not crack or damage the plastic.
Taste and material performance
The bottle is made of BPA-free plastic but does not have any plastic taste, even when outdoors in extremely high heat (105 degrees F), as we encountered during a fishing trip. There was also no odor retention. We also used it with electrolytes and did not have any odor retention or lingering taste after a normal wash.
Filter performance
The LifeStraw Go Series is a filter bottle with a moderate flow rate with suction on the straw mouthpiece, and it is easy to use. It is especially useful where tap water quality is questionable, as it removes waterborne pathogens and viruses. It removes Bacteria (99.999999%, incl. E. coli, Salmonella), protozoa/parasites (99.999%, incl. Giardia, Cryptosporidium), microplastics (99.999%), silt/sand/cloudiness; carbon stage reduces chlorine, organic chemicals, and odors.
A water filter removes contaminants and microplastics, which is ideal for hiking and camping in North America. A water purifier also eliminates viruses and is a safer choice for international travel or anywhere water may be contaminated. This water bottle does not purify water.
Features
The LifeStraw Go Series Filter bottle has a durable body made of BPA-free plastic so it can be used for travel and outdoor adventures.
It has an integrated filter membrane inside the bottle which eliminates the need for a separate filtration device. The membrane microfilter removes 99.999999% of bacteria, 99.999% of parasites, 99.999% of microplastics, silt, sand, and cloudiness. It meets NSFT 42 standard for chlorine reduction, US EPA & NSF P231 drinking water standards for the removal of bacteria and parasites, and the activated carbon microfilter lasts up to 1,000 gallons.
A leakproof screw cap gives a secure seal even when placed horizontally or upside down.
The mouthpiece is covered by a screw-top to keep dirt and dust out, and the wide opening makes it easy to fill from sinks, fountains, and natural water sources.
The sturdy handle makes it comfortable to carry all day, whether tucked into a side pocket or hand-held.
Nine available colorways, as well as stainless steel options

The Ocean Bottle Peak Go serves a very different purpose as compared to the LifeStraw Go Series. It is an insulated everyday hydration bottle rather than a water filter.
The Peak Go holds 24 ounces, has triple-wall insulation, and a flip-lid straw designed for easy sipping on commutes, hikes, workouts, and city exploring. On the other hand, the LifeStraw is built for filtering questionable water sources on the go.

The Grayl UltraPress and the LifeStraw Go Series Filter Water Bottle have filtration technology, so both protect against viruses, bacteria, protozoa, microplastics, and many chemicals. The biggest difference is in the filter mechanism, size, and capacity.
The UltraPress holds 16.9 oz and is lighter and more compact, while the LifeStraw holds 22 oz, making it better for longer outings or if you want to filter more water at once. The UltraPress has a press-down mechanism for filtering water, whereas the LifeStraw filtration is activated when you use the straw to sip and drink water.
If you prioritize portability for travel, day hikes, and everyday carry, choose the UltraPress. Opt for the Lifestraw Go if you're heading on adventures where you'll need larger volumes of filtered water between refills.
