When you’re traveling a little off the grid, having the best portable water filter makes a world of difference. Once you start bringing a portable water filter with you on your trips, it’s a game changer. You don’t have to lug heavy jugs of water on your camping and hiking trips anymore.

Just use your filter to fill the water recipient while you’re on the go. As if that wasn’t good enough news, the best portable water filters pay for themselves in no time. That’s right. You’ll actually be reducing your expenses in the long run. Instead of buying bottles water at marked up prices, simply use the water filter you have to make stream or river water drinkable.

The best portable waters we found make nearly every type of fresh water source drinkable. All of them are durable and get the job done well. They’re easy to use and affordable too which is so important for the budget-minded traveler. When you're on the go, travel accessories like this make all of the difference. In this article, we will take a look at some of the top choices on the market that you can use on the go. 

When Would Having a Portable Water Filter Be Beneficial?

Drinking clean water is integral to maintaining your health as you explore the great outdoors. Remember that once you start bringing your portable filter around, you won’t have to carry as much of a heavy water supply. While it’s true that not all water sources are unsafe, even drinking water from the clearest stream can make you sick. As more of us explore nature, contamination levels rise. It's an unfortunate coincidence but the good news is that there are ways to combat it.The primary way to do so is to use the best portable water filters wherever and whenever possible. 

The best portable water filters come in handy when you’re camping, hiking, biking, and simply just out and about in nature. Just a heads up though. There is a difference between a water filter and a water purifier. Water filters function to sift out protozoan cysts (aka biological pathogens). Purifiers, on the other hand, combat viruses which are most likely too small for water filters to catch.

Enjoy safe drinking anytime and anywhere. This water filter straw from Etekcity can filter up to 1,500 liters of water. This is one of the best portable water filters because it offers three different filtration stages. The first one eliminates contaminants like bacteria, metal ions, chlorine, and other pollutants. When you’re on the go, this is one of the best travel accessories for safe, drinkable water. There’s no need to go thirsty. Just stick the straw in a body of fresh water and sip.

With the ​Etekcity Personal Water Filter Straw, you can access clean drinking water by taking it directly from the source. All you have to do is attached the pre-filter and extension tube to the purifier. Then, take a sip. When you’re on the move, this 16-ounce water pouch can also be used as a hydration pack. Just clip it to your bag for easy access. Once you’ve drank your fill, fill up the cleaning syringe with clean water to wash it out. This will not only keep the purifier ready for next time but also extend its lifetime.

The three stages of filtration are pre-filter, carbon filter, and micron hollow fiber membrane. First, the pre-filter removes any silt worms, rust, or large contaminants from the drinking source. Next, the carbon filter removes contaminants such as chlorine, heavy metal ions, and more potential carcinogens. Lastly, the hollow fiber UF membrane filters particles. It captures more than 99.9999% of bacteria, mold, protozoa, and more, leaving you with clean drinking water.
