Whether you’re planning a backpacking adventure or a trip abroad, one of your biggest priorities will be access to clean water.

We’ve compiled this list of the top ways to purify your water when you’re on the go.

An added benefit? Filtering your own water instead of grabbing bottled water is also an eco-friendly move. You’ll have clean, fresh water without using single-use plastic!

This popular UV purifier comes in a variety of styles, some that come with rechargeable batteries for long outings and others are extra lightweight, which is especially helpful for backpackers. Additional benefits of the Steripen are that the purification takes under a minute and it’s highly portable. However, it does rely on batteries. Since this bottle uses UV light to purify water, you shouldn’t use it on murky water that you can’t see through because it can’t filter sediment.


Boiling water is an easy and free way to sterilize water in areas where it may not be the safest to drink. Although it’s easy, getting your water to a rolling boil is not the most ideal method for hot climates. It can also be time-consuming as you’ll still need to filter the water beforehand to remove any particles. 

Iodine Tablets, solution or crystals

As one of the cheapest (and lightest) option on this list, iodine tablets are a popular choice for those who travel frequently. Despite the popularity of this water treatment, there are a few downsides to this method. You will be able to taste the iodine (though it definitely beats getting sick). It’s also not the fastest method. The iodine takes about 30 minutes for efficacy, so it isn’t ideal for on-the-spot thirst quenching.
