Best Water Treatment Products for Backpackers

The luxury of drinking water directly from the tap or a water bottle isn’t available everywhere and especially when you are backpacking to lesser-developed countries, you should be sure of what you are drinking. Yes, you might be able to buy bottled water or other packaged drinks in those countries but that can be expensive and still might be something your body is ready for depending on the source. To be 100% sure that what you are drinking is good for your health, you can carry water treatment products in your backpack and always drink filtered water.

In this article, we will review the best water treatment products for backpackers that will provide you clean and safe water on demand, without destroying the environment-friendly atmosphere. Here is the list:

Note: It is recommended that you should avoid drinking water tainted with metal and other contaminants that these water filters can’t fully clear out.  Read the manufacturer guidelines and also research the water at your destination location before heading out.

LIFESAVER Systems 4000 Liter Ultra Filtration Water Filter Bottle

1. SteriPen Ultra

SteriPen is one of the most well-known water purifiers among backpackers because of its easy purifying process and lightweight construction. This one is the SteriPen Ultra, which features a UV lamp that emits UV-C light rays which safely purify the water by destroying 99.99% of protozoa, bacteria, and many viruses. You can purify about 16oz. of water in less than a minute with it.

All you have to do is dip the pen into the water and it will sterilize the water automatically, the process sounds easy and fun, right? Yes, it does, but it does have some limitations too. Firstly, it can only be used on clear water, not cloudy/dirty water because it just purifies it (kills the bacteria), not remove it. Secondly, it relies on battery power, which means when you are out of battery and you don’t have a power option near you, you can’t purify the water anymore.

Still, if you want to purify water that is free from dirt and other heavy contaminants then using the SteriPen Ultra is a good option to go with.


  • Easy to use
  • Lightweight
  • Can be recharged via a USB cable that comes with it
  • Works well on clear water


  • Only purifies (does not remove the contaminants)

All you have to do is fill the bottle with water from any source and sip it 5 to 8 times to get clean water, you don’t have to worry about pumping, hoses, batteries and other complex mechanisms.
