Overview
A UV-C lamp at the tip of a tapered neck treats clear drinking water without chemicals, so taste, color and smell stay unchanged. A single button starts the cycle, and the neck fits most wide-mouth bottles and containers.
Treatment with light instead of chemicals means no waiting period and no change in taste, which suits travel bags and emergency kits.
Who it's for
A hiker, international traveler or emergency planner who wants a small purifier that runs on batteries sold almost everywhere. Buyers who want USB recharging, or who treat very cloudy water often, should look at a different design.
Pros and cons
- No chemicals or waiting period
- Taste, color and smell unchanged
- Runs on common AA batteries
- Pre-filter and pouch included
- Batteries are not included
- Intended for clear drinking water only
- Needs a bottle that accepts the neck
Performance notes
Treatment time depends on the volume in the container, so the smaller dose finishes sooner than the full liter. UV-C works by exposing the water to light, which is why the water needs to be clear and why a pre-filter is supplied. Battery condition also matters, since the lamp draws from AA cells.
