Using the SteriPEN
There are five different SteriPEN gadgets to choose from and each serves the same purpose, though they're designed for different situations. Whether you choose the Classic, Adventurer, Traveler, Protector or Journey, you have to decide which model fits your needs.
Once you've decided which of these works best for you, using the SteriPEN is a breeze. To use a SteriPEN, you simply insert the wand section into the cup or bottle of water you wish to purify for the set amount of time and voila, you'll have sterile water. In some cases, adapters are available to make this task easier. For instance, the Journey and Classic are designed to be mounted onto a standard water bottle. In addition, silicone bottle toppers are available that can turn differently sized bottle into a standard-sized water bottle opening. You can then insert the SteriPEN Classic or Journey into the silicone topper for a tight seal.
The most effective way to sterilize water is to use some sort of particle or sediment filter in conjunction with a carbon filter before UV filtering. Of course, the folks who designed the SteriPEN knew this, too. That's why they offer a pre-filter that's designed to remove particles as small as four microns in size.
For those of you who travel abroad and stay in hotels, eat in restaurants and don't plan on wandering off the beaten path, the SteriPEN Classic or Journey might be a better choice for you. These units are designed to work easily with water bottles. For those of you who travel to far away lands in search of hair-raising adventure, you might wish to pack the SteriPEN Adventurer, Traveler or Protector. These units are smaller, and besides, you probably don't have room in your backpack for standard-sized water bottles like a traveler walking through the streets of Mexico City or Paris. Whatever the case, UV sterilization with a SteriPEN can greatly reduce your chances catching a viral infection when you should be enjoying your travel away from home.
