The Classic is also the SteriPEN that gives you the longest battery life. Using four AA lithium batteries, the Classic gives you the power to purify an incredible 200 half-litres of water with a single set of batteries, providing you with that extra confidence to know that you’ll have access to safe drinking water whenever you’re hiking or camping in the wild.
Like Journey, SteriPEN Classic’s tapered end provides a snug fit with water bottles, and with the SteriPEN Fits All Filter, works even with wide-mouth water bottles.
As a reminder, battery quality varies greatly by brand. We recommend using only well-known brand name Lithium or Nickel Metal Hydride batteries. Alkaline batteries of any kind are not recommended.
