Steripen Traveler UV Water Filter

The Steripen Traveler UV Water Filter is a great option for anyone looking for a lightweight way to sterilize small amounts of water at a time. It’s often used by backpackers, but it would also be suitable for bikers or those traveling to foreign countries where the water source would be uncertain. The Steripen may seem a little strange to those used to using tablets or boiling protocols instead of a camping water filter, but it’s backed up by plenty of research and can eliminate most of the bacteria in water that might make travelers sick.

Features of the Steripen Traveler UV Water Filter

One of the most interesting features about this UV filter is that it will fit tightly against the opening of a standard water bottle. You have to swirl the water around while the pen is working to sterilize it, so you can just fit the pen in, turn the bottle upside down, and move the water around as it works.

Other Significant Features

  • The Steripen Traveler UV Water Filter has been shown to eliminate over 99.9% of viruses, bacteria, and protozoa in lab tests, so it gets rid of most of what causes water to make you sick.
  • It can purify 16 ounces of water in 48 seconds, so your average water bottle takes next to no time to purify.
  • At only 5.7 ounces, it’s smaller than almost any other camping water filter on the market.
  • The Steripen can get about 200 uses with a single set of lithium AA batteries.

Pros and Cons

The two biggest pros to the Steripen Traveler UV Water Filter are that it can sterilize bottled water quickly and that it’s super lightweight and easy to pack along on any trip.


  • Lightweight and small enough to put into the most stuffed-full backpack.
  • Works in less than a minute on a regular water bottle and in just over a minute on a larger one.
  • Tells you when it’s working, so there’s no doubt about when your water is purified.
  • Very effective at eliminating bacteria and other organisms that can cause you to get sick from drinking water.
  • Doesn’t affect the taste of water, unlike some purification methods which can leave a chemical taste behind.


  • Works best with lithium batteries, which can be expensive. However, you can use rechargeable batteries to save some cash and some waste!
  • Can only work with relatively clean water – as in water that looks clean. However, you can easily filter water through a tee-shirt or coffee filter before sterilizing it.

Who is the Steripen Traveler UV Water Filter for?

The Steripen Traveler UV Water Filter would work great for someone needing to sterilize water in a foreign country or on a hiking or biking trip. It’s best if you’re looking to sterilize just the water you drink, though, since you can’t sterilize more than thirty-two ounces of water at a time.
