The best-selling portable UV Purifier just got even better! Introducing SteriPEN® Classic 3, your most trusted travel companion, especially when traveling abroad where you require a purifier that kills viruses.

And it's almost too simple to use. There's no boiling of water. No waiting for tablets to dissolve. And no pumping of any sort. Just remove the lamp cover, press the activation button, submerge in water and stir. LED indicators flash to let you know when the water is safe to drink. In just 90 seconds, you'll convert potentially hazardous water into safe, refreshing drinking water.

Exceeds U.S. EPA Standards

SteriPEN® exceeds U.S. EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers. Destroys over 99.9999% of bacteria, 99.99% of viruses, and 99.9% of protozoa when used as directed.

Qualifies for SteriPEN Lamp Replacement

Get an unlimited number of water treatments with the SteriPEN Premium Lamp Life Pledge. When a customer registers a Premium SteriPEN (a model providing 8,000 treatments), SteriPEN will replace the unit with a brand new SteriPEN if the customer uses all 8,000 treatments. Once you use up 8,000 treatments on the replacement model, you'll get another replacement. That extends the life of your SteriPEN, and greatly reduces your cost per liter of water treatment.
