Water Purifier SteriPEN FitsAll with 40 micron filter — SteriPEN portable UV purifier and 40 µm pre-filter

SteriPEN FitsAll with 40 micron filter is a portable water purification system that combines UV-C disinfection with a 40 µm pre-filter to reduce visible particulates before UV treatment. The device uses a UV lamp to inactivate bacteria, viruses and protozoa in clear water while the integrated pre-filter captures sand, silt, algae and other debris that can reduce UV effectiveness. The compact design and combination of particulate removal plus UV disinfection make this unit suitable for travel, hiking and basic emergency water treatment where lightweight, fast and chemical-free purification is required.

Advantages

The SteriPEN FitsAll integrates a UV-C purifier and a mechanical 40 micron pre-filter in one portable unit, allowing for quicker preparation of water for UV treatment by reducing turbidity. UV-C technology provides broad-spectrum inactivation of microbial contaminants without adding chemicals or affecting taste. The pre-filter is effective at capturing larger particles such as sand and silt, protecting the UV lamp from fouling and improving overall disinfection performance. The system is lightweight and designed for field use, requiring minimal setup and no consumable chemicals.

Suitable for

• Backpacking, hiking and camping where compact, lightweight purification is needed
• Travel and international trips where tap water quality is uncertain
• Emergency and disaster water treatment for short-term needs
• Outdoor activities such as fishing and boating to reduce particulates and pathogens

Key specifications

• Disinfection method: UV-C photonic inactivation of microorganisms
• Pre-filter rating: 40 microns for removal of sand, silt and larger particulates
• Target contaminants: bacteria, viruses and protozoa (inactivated by UV-C)
• Design: portable handheld unit with integrated pre-filter
• Operation: battery or internal power for UV lamp (refer to manufacturer for exact power source and runtime)
• Typical use: point-of-use treatment of clear to moderately turbid water after pre-filtration

How to use

Fit the 40 µm pre-filter to the SteriPEN FitsAll and draw water through the filter if collecting from a natural source to remove larger debris. Activate the UV-C lamp according to the device instructions and expose the filtered water to the UV light for the recommended treatment time to inactivate microorganisms. For best results use with visibly clear or low-turbidity water after pre-filtering and follow the device prompts or manual for correct immersion angle, exposure duration and safe handling of the UV lamp.

Usage recommendations

Use the pre-filter whenever treating water from rivers, lakes or other sources containing sand, silt or organic debris. Avoid using the UV purifier with highly turbid or colored water that prevents adequate light penetration; in such cases perform additional filtration or allow particulates to settle before UV treatment. Store the unit dry and protect the UV lamp from impacts; consult the manufacturer instructions for battery maintenance, lamp life and safe disposal.
