The SteriPEN Classic Safe Water System includes the SteriPEN Classic, the Water Bottle Pre-Filter and a Nalgene® BPA-Free wide-mouth water bottle. The 40x40 micron screen Pre-Filter fits snugly on the wide-mouth water bottle, protecting the drinking threads, and allows clear water to flow into the bottle while removing particulates.
The SteriPEN Classic is the workhorse of the SteriPEN family. It’s a product that you can consistently rely on for its ruggedness and performance.
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 liters 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 the 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.
