Ultralight UV Water Purifier

Jump to: Our Verdict / Features / Specifications

A compact UV water purifier perfect for travel, emergency preparedness or anytime. It’s easy to use with water activated programming and produces 1 liter of purified water in 90 seconds.

Steripen says

A pocket-sized water purifier for any adventure. Toss the SteriPEN® Ultralight UV in your carry-on, backpack or emergency kit so you’ll always be able to make clean water. The USB-rechargeable battery is easy to top up from your computer, a wall charger, a solar panel or a car. No buttons, no moving parts – just fill your water bottle from a creek, rain barrel or tap, then submerge the lamp and stir to create clean, potable water.

Our Verdict

SteriPEN’s Ultralight UV Water Purifier is very lightweight which is one of the main reasons we stock UV water purifiers as the are often very lightweight. This is important as you should really pair one of these up with a water filter too to get the maximum effectiveness of the system.

We always appreciate rechargeable batteries and being able to treat 20L of water from one charge makes it sufficient for a good few days out on the trails. Pair it up with a solar charger and you could treat water for much longer trips.
