Portable UV water purifier SteriPEN Ultra — handheld UV disinfection device for treating drinking water

SteriPEN Ultra is a portable UV water purifier that uses ultraviolet light to inactivate bacteria, viruses and protozoa in drinking water. Designed for outdoor use and travel, this handheld device treats water drawn from lakes, rivers, taps or storage containers. The compact, battery-powered unit delivers rapid treatment cycles and simple immersion operation to reduce microbial contamination and improve safety of potable water in field conditions.

Advantages

The SteriPEN Ultra provides chemical-free disinfection without altering taste or odor. Its compact handheld design and battery operation make it suitable for remote use where filtration or boiling are impractical. Fast treatment cycles allow preparation of drinking water within a minute for typical serving volumes, and the immersion method is easy to use with a wide range of container shapes. The device is lightweight and intended for repeated use with minimal maintenance.

Suitable for

• Backpacking and hiking trips where safe drinking water is required
• Camping and outdoor recreation with natural water sources
• Travel to regions with uncertain tap water safety
• Emergency preparedness and disaster response kits
• Treating water from taps, wells, rivers, lakes or storage containers

Key specifications

• Disinfection method: ultraviolet (UV-C) inactivation of microorganisms
• Power source: replaceable or rechargeable batteries (battery-powered operation)
• Operation: handheld immersion use for direct treatment in containers
• Treatment time: rapid cycles suitable for typical personal serving volumes (approximately under one minute per litre depending on conditions)
• Portability: compact and lightweight for outdoor and travel use
• Maintenance: limited routine maintenance, periodic battery replacement or recharging and lamp care

How to use

Fill a suitable container with raw water from the source to be treated. Power on the SteriPEN Ultra according to the device instructions and immerse the UV lamp into the water, ensuring the sensor or lamp is fully submerged as specified by the manufacturer. Stir or move the unit gently to expose the water uniformly to UV light for the required treatment cycle. After the cycle completes, remove the device and store it dry. Use treated water soon after disinfection and follow any manufacturer guidance about maximum turbidity and prefiltration if necessary.

Usage recommendations

For best performance, use the SteriPEN Ultra with clear water (low turbidity); if water is cloudy, prefilter or let particulates settle before UV treatment. Keep the lamp and optical surfaces clean and replace batteries as recommended. Do not use the device on highly turbid or chemically contaminated water; UV treatment inactivates microorganisms but does not remove chemical pollutants or particulates.
