## Description

The SteriPen UltraLight is an ultralight travel UV water purifier designed for backpackers and travelers. In just 90 seconds, it eliminates 99,9% of viruses, bacteria, and protozoa from one liter of water. Ideal for destinations where a mechanical filter alone may not be sufficient, ensuring safe hydration on the trail or in remote areas.

## This could come in handy for you.

Compact and ultralight UV water filter that charges via USB.

## Steripen UltraLight UV lamp

The Steripen UltraLight UV lamp is an ultralight travel UV water filter that can purify **one liter of water in just one cycle lasting 90 seconds**. The UV radiation **removes 99,9% of viruses, bacteria, and protozoa** from the water by breaking down their DNA/RNA.

On a single charge, the UV lamp can handle up to 20 cleaning cycles, which means it can purify up to 20 liters of water.

The internal **Li-Ion battery** charges using the **micro USB cable** that's included in the package.

The lamp's lifespan is **up to 8000 cycles**.

In most cases, it's enough to use a mechanical filter to clean the water, which will filter out bacteria, sediment, and other larger impurities. However, a mechanical filter is not sufficient for viruses. **Ultraviolet radiation, which will eliminate all microorganisms including viruses, is definitely a safe bet.**

## Cleaning Process

- One cycle of irradiation cleans a maximum of 1 liter of water.
- Turn on the UV lamp by pressing the button.
- If you want to light up just 0,5 liters of water, press the button 2x – it'll cut down the heating time.
- Submerge the stick in water up to the electrodes.
- During the whole ozonation process, the electrodes must be submerged in water; otherwise, the cleaning cycle will interrupt itself.
- If the water is murky / visibly dirty, make circular motions with the lamp so that the UV light reaches all the water molecules. Sediment and dirt can block the light throughout the volume of water.
- Once the filtration is complete, the green LED will light up and the lamp will turn off by itself.
