Turn to the SteriPEN Adventurer Opti if you're looking for a compact Water Purifier that's easy-to-use, effectively treats water, and leaves no funny aftertaste. Chemical treatments can take up to 30 minutes to treat the water, and hand-pump options leave your arms too tired to pick up that backpack or paddle. The Adventurer Opti conquers any potentially harmful microorganisms in just 90 seconds per liter—and WITHOUT the funny aftertaste. Plus it also effectively treats against viruses, making it a viable option for use abroad. No wonder it received Backpacker Magazine's Editor’s Choice Award!

Treatment is simple. Just push the button, dunk the lamp into your water, and gently stir. Once it displays the green light, you're ready to take that next safe swig of water. Please note: Its product profile works best in containers with a minimum 1.75" diam. opening (think Nalgene wide-mouth or 1-liter bottles).

Qualifies for SteriPEN Premium Lamp Replacement.

This model qualifies for the SteriPEN Premium Lamp Life Pledge. The Lamp in your model provides up to 8,000 treatments. When you register your Premium SteriPEN, you'll get an unlimited number of water treatments beyond the original lamp.

Just register your SteriPEN, and when you reach 8,000 treatments, SteriPEN will replace your Ultra UV Purifier. That extends the life of your SteriPEN, and greatly reduces your cost per liter of water treatment.
