Best Water Filter Bottle

Drinking water is the most important we need to survive. While it is easy to refill from tap when at home or at refill stations, it can be a little more challenging when traveling or outdoors (hiking, camping, kayaking).

The easiest way to stay hydrated and healthy is a filter bottle for your adventures. You are able to refill and drink from wild streams, waterfalls or even puddles.

There are already many different travel water filter bottles you will find when researching. 
They are all similar but different too.

Make sure to know exactly where you like to use them and what you need to have filtered out. 

Most of the filters do only filter bacterias (99.9999% of bacterias and 99.9% protozoa).
So if you travel to a place where 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….) 

Always read the description of the filter bottles carefully, to get the best one for your needs.

 I looked into some of the best known on the markets at the moment:

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.

  • 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.
