Which SteriPEN Is Best for Backpacking?

By Michael Ferguson

Backpacking is an exciting way to explore the wilderness and take in new sights while getting some exercise in the process. It can be a great way to bond with friends and family and make memories that will last a lifetime.

However, going on a backpacking trip can be dangerous if you don’t plan ahead. One of the most important things you should consider is the type of water purification system you will need for your journey. There are many different options available, but one of the most effective and compact systems is the SteriPEN.

SteriPENs are small, portable purification devices that use UV light to destroy bacteria, viruses, and protozoa that can make drinking water unsafe. They are easy to use; all you have to do is submerge the SteriPEN into your water source, click a button, and wait for it to finish its cycle.

There are several different models of SteriPENs available on the market today, each with its own unique features. The SteriPEN Classic 3 is one of the least expensive models available and comes with a built-in lithium-ion battery that can be recharged via USB or solar panel. It also has an LED indicator light that tells you when it’s finished purifying your water.

The SteriPEN Adventurer Opti is another popular model for backpacking trips. This model features an LCD display with multiple language options as well as a 0.5 liter measurement line so you know exactly how much water you have purified at any given time. The Adventurer Opti also has an integrated flashlight so you can easily see what you’re doing in dark conditions or when setting up camp at night.

If you’re looking for something even more advanced, then the SteriPEN Journey LCD might be right up your alley. This model comes with an LCD display that tells you how many liters of water have been purified as well as how much battery life is left in it before needing recharging or replacing with new batteries. Additionally, this model also has a pre-filter system so you don’t have to worry about large particles getting into your drinking water while purifying it with UV light technology.

When deciding which type of SteriPEN is best for backpacking trips, there are several factors to consider such as cost, size/weight, ease of use, battery life/rechargeability, and features such as integrated flashlights and LCD displays.


For those looking for something lightweight yet effective for their backpacking trip needs, then any one of the three mentioned above should suffice; however if weight isn’t too much concern then opting for something like the Journey LCD would be best due to its added features like an LCD display and pre-filter system.
