Best water filter bottle: water treatment for hiking, travel or camping
Why you need the best water filter bottle?
When traveling, hiking, backpacking, camping one of the most important things is to stay hydrated! (Check how much water you should bring for a day hike)
But depending on where you are it is not always that easy. Not always that easy if you like to avoid single use plastic bottles…
I grew up in a country where we can drink tap water. But this is not the case everywhere. In a lot of countries they don’t have safe drinking water from tap. Chemicals, viruses, bacteria can make humans sick when drinking this water.
And while hiking through the back country it sounds easy to drink from wild streams, rivers and waterfalls, but be careful about parasites, protozoa, bacteria that you can’t see.
So what I hear when I talk to zero wasters, or plastic free enthusiasts is this: “When I travel I need to buy plastic bottled water. There is no way around it! I need to, because there is no safe drinking water from tap.”
But this is NOT true!
When you research a little, you will find out that there are many options out there, and every outdoor enthusiast and hiking expert will know this already.
So before you buy loads of plastic bottled water while traveling, spending a lot of money, and producing heaps of plastic trash, that most likely won’t get recycled, and before you risk getting sick while drinking from wild streams you can do something else. You can find your favorite water treatment system, your favorite water filter bottle.
Water treatment systems
When talking about water treatment systems for drinking water you will find 4 different methods:
- boiling water
- UV treatment
- different kind of filter
- chemical treatment (liquid or tabs)
This is a great way to make water safe to drink. Boiling water kills bacterias and most viruses.
You will hear different times when you research for boiling time. I always stick to 4-5 minutes of boiling when I have a kitchen. When you are out backpacking and need to save gas, 1 minute seems to be enough and 3 minutes when above one mile of elevation.
We boiled tap water in Mexico city. I used my filter bottle too because I wanted to make sure, my boyfriend didn’t and neither of us got sick.
Pro: awesome easy and free way to make water safe to drink.
Con: You need a kitchen or camping stove and this will not be a solution in cities where you have chemicals in the water.
UV treatment is one of the most effective methods of water treatment. It is very easy to use and does not leave any unpleasant taste in the water, like some of the chemical treatments.
It kills bacteria, viruses and protozoa and is over 99% effective.
Batteries are needed and you need to order them online before you travel as they are not a standard size. The batteries are enough for 25-50 liters of water.
I personally haven’t tried it yet, but friends of mine travelled with the Steripen* through India, drinking tap water in Bangladesh without getting sick.
Pro: easy to use, lightweight and very effective. Great for travel and hiking.
Con: not effective against chemicals.
This is the Steripen UV filter my friends recommend.
- Compact UV water purifier, specifically for outdoor/expedition use; Reusable for up to 8,000 liters of water
- Destroys more than 99.9% of harmful microorganisms, including Giardia, bacteria, viruses and protozoa
- Safe and effective without altering taste. Chemical-free
- Water sensor doubles as an LED flashlight
Different kind of water filter systems
When it comes to water filter/purification you can find many different systems.
- From small and lightweight to big and heavy.
- From filtering small amounts and slow dripping, to big amounts and quick.
- From dripping, to sucking, from pumping to squeezing.
- Some does only filter bacteria, and no viruses, no chemicals. Some filter viruses, bacterias and chemicals. So make sure to know where you are going, what might be in the water and what you might need.
Lightweight and small is perfect for backpacking and travel, while when you are camping or have a base somewhere for a longer time, big, bulky and heavy is not a problem and makes sure to get a bigger amount of drinking water quicker.
If you travel to a developing country, where viruses could be in the water, you might want to get a filter that purifies and filters 99.99% of all contaminants (bacteria and virus and maybe even chemicals).
I like to introduce you to a few of the most common and favorite filtration systems and brands.

Con: Only great for small amounts. Needs regular back flushing, or it get’s hard to use. Doesn’t filter viruses and chemicals.
Best Water Filter Bottles:
There are many different filter bottles on the market. Make sure to know what you want to have filtered out.
Most of the filters do only filter bacterias (99.9999% of bacterias and 99.9% protozoa), so if you are concerned about chemicals and viruses, make sure to get a purifier that filters 99.9% of all contaminants (chemicals, bacterias, viruses, chlorine, fluoride….)
When I first started to live a single use plastic free life, I was worried about traveling because I didn’t know how to avoid plastic bottles, and then I researched and asked around on facebook.
A friend recommended the water to go bottle. She traveled around South East Asia with that bottle and didn’t get sick and didn’t need to buy any plastic bottles. So I ordered two bottles straight away before we traveled to northern America (Canada, USA, Mexico). Long story short, we drank water from tap in Mexico, from dodgy taps in a national park hotel in Canada, from rivers and lakes and never got sick. You can read more about my experience and about the benefits of a filter bottle here-> My favorite travel bottle.
- The unique Water-to-Go filter technology eliminates over 99.9% of all Bacteria, Viruses, and chemicals (Chlorine, Fluoride and Heavy Metals such as Lead)
- This bottle has 75cl capacity and weighs 138g (with filter)
- It is BPA free / all materials and FDA approved, plastic bits are recyclable and filter compostable
- Bottle is Dishwasher Proof (Lid is hand-wash only)
- The filter is effective for 200 Liters which is roughly 3 full bottles per day for 3 months.
Pro: Very easy to use. Filters viruses, bacterias and chemicals.
Con: Filter needs to get replaced after 2 month (50ml bottle) and 3 months (75ml bottle) And the lid is leaking a little bit on our bottles (we have the 50ml bottles) . But these sports caps leak from most brands bottles. I do hope this will get fixed in the future. (Update: they now have a new cap that looks very good, haven’t tried them yet).
-Another con is, that while the plastic material they use is highly recyclable, black plastic can´t get detected by any recycling sorting machines, so make sure to bring them to a private plastic recycling firm that does not use a sorting machine-

Find the one that suits your desire the most.
Pro: Easy to use. Easy to carry around. Lightweight. Has different options for different desires.
Con: They don’t have the one filter that filters out everything. It is very hard to suck the water through the filter in the beginning, but it can become easier after a while. The normal filter does not filter viruses and chemicals. So if you are concerned about viruses, get the “Life Straw Mission Purification system*” or the
I just recently discovered the Grayl Bottle and had no chance yet to try it. Looks nice and easy to use a girl in a travel facebook group recommended them. While this one is a little bit more expensive than the Water-To-Go bottle, it does have the advantage that you don’t need to suck on the bottle to drink, (after a few weeks that does “suck”) and could even use the filtered water for cooking too.
- Removes viruses, bacteria and protozoan
- Filters many chemicals (e.g. chlorine, benzene) and heavy metals (e.g. lead, arsenic);
- zero aftertaste, eliminates bad odors, improves clarity and flavor
- Fast and easy-to-use, simply Fill. Press. Drink. No sucking on the bottle to get the water out of there.
- Filter lasts about 150L /2-3 months of water, depending on how much you use it.
Pro: No sucking on the bottle. Filters everything from chemicals, bacterias, viruses…
Con: Can be hard to push down to filter the water after it got used a few times. A little more expensive, but ok for traveling through countries and cities where you are concerned about chemicals and viruses.
If you don’t like to suck on bottles or like to get an extra safety feeling or just to have something in back hand if the filter might get broke, there are chemical treatments too.
They mostly taste not too nice though, because based on chlorine and the tabs need a bit time (from 30 minutes) until you can drink the water.
You can choose between liquid treatment (drops)* and tabs*.
Con: they taste not too good, and shouldn’t be used on a regular basis.
So what is the best water filter bottle?
I can highly recommend the water to go filter bottle. I like that they filter bacterias, viruses and chemicals.
But for camping with groups and longer hiking trips I would definitely recommend a Gravity drip filter system so I don’t need to suck on a sports cap bottle all the time and easily can use filtered water for cooking.
Make sure to know what you need. A filter for bacterias, parasites when hiking? A filter for bacterias, parasites, viruses and chemicals when traveling? And always double check for those informations before you buy a filter bottle.
A lot of filter bottle are called purifier or filter bottles but don’t filter all of these, so please double check what you need, want and what the filter bottles actually filter!

Do you have a filter bottle already? Please tell me which one and if you are happy with that system. And if you don’t have one I highly recommend getting one for your next trip! Saving money and plastic trash because you don’t need to buy plastic bottled water is a win win situation for you and the environment 😀
