So you’re looking for the best water bottle with filter for travel? When it comes to choosing the right one it’s important to focus on the details.
But first off a warning – not all filter water bottles do the same job.
You might even be surprised to know that the vast majority of filter water bottles won’t actually make your water safe to drink.
The fact that you’re looking for a water bottle with built in filter suggests that you want to improve the quality of what you’re drinking.
And if you’re planning to take it on your travels that means it’s gonna have to work pretty hard.
When you’re drinking from unfamiliar water sources, whether at home or abroad, it’s best to take strong precautions.
And while many places have tap water that’s perfectly safe to drink, it may still make you ill.
This is because water quality and content varies widely from place to place. It’s treated differently, contains different minerals, salts, metals, and originates from different sources. There are different chemicals added such as fluoride or chlorine.
All of these things make a huge difference to the flavour profile of tap water. But they could also upset your stomach if it’s not used to that content, however “harmless” it is.
Best Water Bottle With Filter for Travel
We’ve been travelling full time since 2015. In that time we’ve discovered how important clean, safe water is.
We know what makes a good water bottle with filter for travel and what doesn’t.
Unlike a lot of the posts that you might read on the best water bottles with filters for travel, we’re taking a different approach.
After thorough testing and research, there are actually only 2 bottles that we believe are up to the job.
They are also both reasonably priced, particularly when compared to lots of other models that are far inferior.
So rather than list everything on the market, we’re simply narrowing it down to these two. We’re 100% confident that you can’t get a better water bottle with filter for travel.
Travel Water Purifier Bottle or Travel Water Filter Bottle: What’s the Difference?
There are literally hundreds of travel water filter bottles on the market. Because of this it can get confusing trying to figure out which is best for you.
Most travel water filter bottles are designed to simply alter the taste, smell, and reduce the amount of chlorine present.
This works great with tap water that you know is safe to drink. So if you’ve done the research and are certain that’s the case then you should be fine with just a filter water bottle.
Something Like the LifeStraw would probably be sufficient.
However, perhaps you’re going somewhere with questionable water standards.
Or it could be that you plan on filling up from sources other than a tap.
Or maybe you just want the peace of mind that what you’re drinking is absolutely safe wherever you are.
For this you’re going to want to purify your water rather than just filter out any bad tastes or odours. That’s where a travel water purifier bottle comes in.
The best water purifier bottle will do everything that a water bottle with filter for travel does. It will remove any bad smells or tastes and reduce chlorine. But it will also go one step further.
A travel water purifier bottle is able to eliminate a whole host of hidden nasties.
These include bacteria, protozoa, parasites, and the real biggie, viruses.
This means that you are able to drink from virtually any water source with no worries about getting ill.
When you’re out adventuring this is not only a massive money saver but could be a life saver.
Reasons to Use a Travel Water Filter Bottle
1. Safe Drinking Water
The first and most obvious reason for using a water bottle with filter for travel is to ensure you’re drinking safe water. But you need to be sure that the one you choose is going to cut the mustard for your destinations.
For example if you’re out in the wild then rivers or lakes are a fantastic option for providing your water.
But you can’t be certain that the water is safe to drink. Regardless of how clear it may look, it could contain all kinds of stuff that you don’t want to ingest.
This goes for tap water in many countries where standards aren’t as high as what you’re probably used to.
Locals might drink it and be fine, but that doesn’t mean it’s OK for you to guzzle down.
2. Reduce Plastic Waste
The second most important reason to use a water bottle with filter for travel is to help reduce plastic waste.
Single use plastic water bottles are one of the largest contributors to the current global plastic crisis.
When you’re travelling, often bottled water would be your only safe option. However, with a travel water purifier that’s not the case.
By not purchasing bottled water you’re helping to stop the quickly developing environmental crisis caused by discarded plastic bottles.
3. No Dodgy Bottled Water
Another scary fact about bottled water is that often you may not be getting exactly what you bargained for. A third great reason for using a water bottle with filter for travel.
There are loads of stories of unscrupulous people selling bottled water that has essentially come out of the tap.
Not only is this a huge waste of money for you, but it could result in you becoming extremely ill.
Because it’s been bottled illegally, there are zero health and safety standards adhered to.
Best Travel Water Purifier
If you’re looking for a great water bottle with filter for travel then there are plenty of options. However, if you decide to go for a travel water purifier, your options are more limited.
Most have bulky mechanisms that take lots of manual work to function, or require batteries. These are completely impractical for everyday travel when you just want to be able to fill up your bottle and go.
Because of this, there are currently only two models that make the grade to be considered the best water bottle with filter for travel.
That’s not to say you won’t find plenty of other options available that will purify your water.
But these two are by far and away the most convenient and the only ones that we’d use for everyday travel.
GRAYL Geopress Water Purifier
The GRAYL Geopress is our top pick for the best water bottle with filter for travel.
GRAYL began life on Kickstarter where their first funding drive raised over $250,000.
From there they’ve refined the technology and created what we think is the best water bottle with filter for travel on the market.
The GRAYL Geopress Filter
The GRAYL Geopress filter removes 99.9% of contaminants. These include bacteria, viruses, water borne disease, protozoa, heavy metals, and harmful chemicals.
GRAYL filters have 3 mechanisms which remove anything harmful as well as making the water taste great.
Usage and Lifespan
Using the GRAYL is pretty simple and virtually effortless. Firstly you unscrew the lid, pull the filter out and then fill the outer vessel up to the fill line.
Next you put the filter back into the outer vessel and force the filter through the water.
The easiest way to do this is by placing it on the floor and using your body weight.
Make sure it’s on a hard, flat surface that’s stable. Then put the heels of your palms onto the press before leaning onto it with your upper body.
And that’s it. Within 8 seconds you have safe, delicious drinking water from virtually any source.
You can then fill up other vessels, guzzle it down, or screw the cap back on and throw it in your bag.
GRAYL Geopress are designed to last 350 presses, that’s 65 gallons or 250 litres.
You’ll know when it’s time to replace your filter as the time to squeeze the bottle’s filter mechanism down will gradually increase.
While it still works to purify your water, you should switch it out once it starts taking 25+ seconds.
The GRAYL Geopress only currently comes in a single size which purifies around 24 ounces or 710 ml.
The fact that the water free-pours is a distinct benefit as it means that if you want more, you can just pour it into other bottles and purify another lot of water.
The bottle comes in a range of 4 colours which all look pretty cool.
Size-wise it’s perfect to pop in the side pocket of your backpack or day pack.
It’s also got a handy plastic loop on the lid. This can be clipped to a carabiner or used to tie it onto your bag.
The Grayl is made from strong plastic – a mix of polypropylene #5, food-grade silicone and ABS food-grade plastics.
This makes it extremely durable and ready to withstand the rigours of daily travel.
Cleaning the GRAYL is straightforward, you just have to disconnect all of its parts.
Most of it can go in the dishwasher but it’s just as easy to wash it all in some warm soapy water.
The filter itself can be rinsed but shouldn’t require cleaning as such.
The GRAYL is a fantastic piece of kit that has no major drawbacks to speak of. However, there are a few things to be aware of.
Some people might find the capacity a bit on the small side, but the fact that you can fill other bottles from it negates that.
The fact that you have to manually filter the water may also appear to be a negative. However, the bottles have comfortable, ergonomic grips and using your body weight makes it super simple to do.
The GRAYl Geopress is relatively expensive when compared with our other recommendation. Despite this, you can’t put a price on your health so we believe it’s worth every penny.
The GRAYL is suited for every kind of adventure, from hiking and camping to general everyday travel.
If you’re camping or hiking and you need water for cooking then the GRAYL is ideal.
It’s also good in situations where you need to purify larger quantities of water because you can easily fill up other vessels from it.
These Water-to-Go bottles are our runner up for the best water bottle with filter for travel overall.
We used them ourselves for over 2 years, and we love love love them. In fact they still accompany us wherever we go, home or abroad.
What’s so great about them? They have the most complete technology available meaning everything that can and should be filtered, is.
The Water-to-Go Filter
The filters themselves are where the magic in this travel water purifier lies. They’re made using NASA technology and uniquely combine 3 filtering techniques.
The technical bit goes a little over my head, but the important takeaway from it is this.
They remove 99.9% of all microbiological contaminants including bacteria, viruses, water borne disease, protozoa, heavy metals, and harmful chemicals.
Check out the full scary looking list here to see exactly what they will eliminate from your water.
Usage and Lifespan
Water-to-Go bottles are really simple to use, and unlike most water purifiers don’t have a mechanism or require batteries.
All you have to do to use them is activate the filter by soaking it in water for around 15 minutes.
After that you can simply drink from the bottle like a normal sports bottle. The flow rate is a little slower than your average sports cap but we’ve not found that an issue.
The filters last for three months or 200 litres of water filtered. But unlike with other filters, they still carry on working to filter out the dangerous elements after this.
The bit that stops working is the carbon which removes the taste and odours from your water.
So it’s feasible that you could use it longer than three months, though this wouldn’t be recommended.
To replace the filter you simply unscrew it and screw a new one in. The outer casing can then be recycled and the inner filter is biodegradable, perfect for composting.
They come in two sizes – 50CL or 75CL – and various colours for you to choose from.
For travelling, we’d suggest the larger capacity 75CL bottle is more suitable. It allows you to fill up less which can be helpful when there aren’t many water sources around.
It will also fit perfectly in the side pocket of your backpack or daybag making it easy to carry around.
The ergonomic design makes it easy to hold and drink from with its indented handgrip.
The Water-to-Go bottles are made from durable, BPA-free plastic and are extremely rugged.
We’ve had ours for over 2 years in which time they’ve been up mountains, on multi day treks, and all over the globe.
We have broken one, but that was when it dropped out of a bag while cycling along a dirt path. The bottle was full and cracked on impact.
However, other than that they have stood up to the rigours of daily travel over a long period of time.
The 75CL bottles are dishwasher safe although we find them simple enough to just clean them by hand. They have a large opening when you unscrew the lid which helps this.
Simply unscrew the cap, remove the filter and give them a good scrub. It’s best to clean the cap quite regularly as it’s the only bit after the filter. Bacteria from your mouth, surrounding environment etc. could collect there.
Some other filters have issues with things growing on them or getting clogged up. However this has never occured with our Water-to-Go bottles and we’ve used them in some pretty questionable water.
While they are incredible and we trust them to keep our water safe, they have a few minor limitations.
Water-to-Go bottles aren’t designed to be squeezed or poured. It is possible to squeeze water out of them but it’s a little difficult and comes out at a slow rate. Because of this they really are only for drinking from.
Why is this significant? Well if you need to purify water for other uses, for example to cook with, this isn’t your best bet. That said, we’ve never really had an issue with this.
Another minor complaint we previously had about the Water-to-Go bottle is that the drinking spout would leak if they were not kept upright.
However, the latest version of the bottle comes with a new-style cap which has addressed this issue.
The Water-to-Go bottle is ideal for everyday usage for drinking water. Its hassle free technology makes it easy to simply fill up and drink from virtually any source with no worries.
No pumping, no waiting, no batteries. This means that filling up in places where you’re unsure about the water quality takes just seconds.
Don’t Forget Your Travel Insurance
Regardless of what kind of getaway you are planning, one of these two options will undoubtedly be the best water bottle with filter for travel for you.
But making sure you’re drinking safe water isn’t the only sensible planning step to take before you travel.
We never go anywhere without travel insurance – and neither should you. You need to make sure you’re adequately covered in any situation that may arise.
Our preferred insurance company is World Nomads, they take a no nonsense, upfront approach. Get a quick quote below:

Thanks for your filter water bottle article! Going to travel to Guatemala this week and I purchased two Watertogo bottles! Super helpful as I have little time to research.
Hey Anais, great to hear, hope you have a brilliant time in Guatemala!
I am a water scientist.
If you know that the water issue is bacteria, the filter is enough but if chemical pollution such as Bali, Jakota, heavy metal and other chemicals. Water needs to be ionized to break acidic particles. Not easy. It takes time. Talking 2 days of flocculation process.
I would say, LifeStraw or any list of filter can’t handle chemical contamination that lead to kidney or brain permanent damage.
Including look fresh river water, you need to know TDS measurements. those device costs $200+ US marks so safe to bring purified water.
Hi there, all of the details in this post are taken directly from what the manufacturers say and they specifically state that the filters in the models featured in this post filter chemicals and heavy metals.
I’m not a water scientist but have no reason to doubt the manufacturers’ claims. From personal experience I can say that we have never been sick in the 4 years that we have used these filter bottles.
I purchased the GRAYL Geopress to filter my municipal tap water to filter out any potential particles, chemicals, and/or heavy metals. And we have not experienced any health problems when drinking water from this filter. Highly recommended!
So great aren’t they! We love them!
Awesome, thanks for sharing your tips! I’m looking forward to using my water filter on my next trip.
Such a handy piece of kit to have – we don’t go anywhere without ours!
