SteriPen Adventurer Opti – Water Purification At Its Best

[amazon_link id=”B0044DDQEG” target=”_blank” container=”” container_class=”” ]SteriPen AdventurerOpti Water Purifier (Black with Green Accents)[/amazon_link]Water purification is a very important consideration when planning a backpacking trip, especially when the trip is more than a few days. You won’t last long on the trail without fresh, clean water, so it is vital to have a method for purifying water while on the trail. When it comes to water purification, there are many different methods for obtaining clean water. Iodine tablets, boiling water, and water filters have been the most popular methods in the past. But with improved technology and innovation, SteriPen has developed a ground-breaking new method for purifying water – utilizing UV light to kill harmful microorganisms. All of this is done with a small, handheld device called the SteriPen. One of their best selling models, the SteriPen Adventurer Opti, is an award winning water purifier that every backpacker should take with them. Let’s look at some of the features below.


The SteriPen Adventurer Opti is the lightest SteriPen on the market, weighing in at only 3.6 ounces with batteries. Compare that to the weight of a small backpacking water filter, and you will see why this water purification system was named a Backpacker Magazine Editors’ Choice award winner in 2011. The SteriPen Adventurer Opti utilizes a UV light bulb to kill all microorganisms that could be in the stream, river, or lake that you are pulling your water from. For half of a Liter, it takes 45 seconds, and a full Liter takes only 90 seconds.

The UV light emitted from the SteriPen Adventurer Opti kills:

  • giardia
  • cryptosporidium
  • bacteria
  • viruses

It is important to remember that this is NOT a water filter. Use a coffee filter or bandanna to remove sediment from the water before zapping the microorganisms with the UV light.

The Adventurer Opti can be coupled with an optional solar charging panel, which can fully charge the provided rechargeable CR123 batteries in 4-6 hours. These rechargeable batteries are capable of purifying 40-50 treatments before needing to be recharged.

Other SteriPen Adventurer Opti highlights:

  • 3.6 ounces of total weight (including batteries)
  • 6.1 inches of maximum dimension
  • 100 treatments from disposable CR123 Lithium Batteries
  • Up to 8,000 treatments from UV bulb
  • optical sensor doubles as a flashlight (3 minute bursts)
  • fits most wide mouth water bottles

Backpacking Samurai Thoughts

It is easy to see why the SteriPen Adventurer Opti was chosen by Backpacker Magazine as an Editors’ Choice award winner in 2011. This water purifier is simply one of the best options on the market today. There are tons of accessories for the Adventurer Opti available as well, like the solar charging panel, 12V car charger, and the SteriPen pre filter. I also noticed that the taste of the water was phenomenal when purified with the SteriPen. Sometimes water filters remove everything from the water, leaving it with the taste of bottled water. The SteriPen just zaps the water with UV light for 90 seconds, and doesn’t remove anything. It allows you to enjoy the sometimes wonderful taste of nature. If you are an avid outdoorsman, this is the water purifier for you. Click the link below to buy this award winning ultralight backpacking water purifier now.
