Steripen Adventurer Opti

Top Steripen Portable FilterThe Steripen Adventurer Opti is a handheld UV water purifier that is designed to destroy microorganisms. Steripen has been around since 1999 and was started by a guy named Miles Maiden, a dedicated outdoorsman. He felt the need for a way to provide safe drinking water anywhere he went and followed it. Since then, Steripen was featured in Time magazines top 100 gadgets of all time! The Steripen completely destroys almost 100% of microorganisms like bacteria, giardia, tons of different viruses as well as protozoa. Since the purification is done through UV light it does not introduce your water to any chemicals or alter the taste.

I find this to be the perfect tool for a long hiking trip in the woods where packing a large water supply is impossible.  When you stumble upon a water source, fill your cup or water bottle, whip out your handy Steripen and begin stirring your water. This will yield completely safe drinking water wherever you’re at! Pick up Steripen Adventurer Opti if you’re looking for an extremely portable solution for unsafe drinking water.

This type of disinfection is actually more effective than popular solutions like chlorine and iodine. Using the MSR Miox with your water source will actually completely destroy some viruses and bacteria in just 15 minutes. However there are some harder to destroy bacteria and viruses than can take up to 4 hours to kill. But don’t worry, the Miox has a built in safety indicator that will let you know if your water is safe to drink once it is treated. 

The Miox is completely maintenance free unlike many other types of travel water filtration options. The battery and salt life is nearly endless and is very easy to replace once it does come time to replace. The Miox works best for large amounts of water, which makes it great when you’re traveling with a larger group of people.
