Katadyn SteriPen Ultra UV Purifier

Katadyn SteriPen Ultra UV Water Purifier

A compact, rechargeable UV water purifier that destroys 99.99% of protozoa, bacteria, and viruses in under 90 seconds without chemicals, pumping, or waiting for a filter to do its work. The SteriPen Ultra is the right tool for international travel and backcountry use where virus protection matters as much as bacteria and protozoa removal.

Why We Carry It
It's the purifier we recommend for international travelers and backcountry users who need virus protection that standard hollow fiber filters don't provide without the chemical taste of iodine or chlorine tablets.

Highlights

• Destroys 99.99% of protozoa, bacteria, and viruses — UV-C light purification that works against threats hollow fiber filters miss including viruses that cause cholera, typhoid, dysentery, and botulism. A critical distinction for international travel and high-risk water sources where viral contamination is a real concern.
• 0.5L purified in under 60 seconds, 1L in 90 seconds — One of the fastest water treatment methods available. Click a button, agitate gently, and the water is safe to drink before you've finished checking your map.
• 2,200 mAh rechargeable Li-ion battery via USB — Charges from any USB source including solar panels, laptops, and car chargers. Up to 50 liters per charge with a low-power indicator so you're never caught off guard on a long trip.
• Up to 8,000 uses over the unit's lifetime — A long-term purification investment that pays for itself many times over compared to chemical tablets or disposable filter cartridges.
• Fits store-bought water bottles — Insert the lamp into a standard water bottle and flip upside down for treatment without a wide-mouth bottle or specialized container. A practical compatibility detail for international travel where store-bought water is the starting point.
• Watertight seals with rubberized grip — Electronics stay protected in wet conditions and the rubberized grip stays secure in wet hands during treatment.
• Automatic shutoff when treatment is complete — No timer, no guessing. The SteriPen turns itself off when the UV dose is delivered so you always get a fully treated result without overthinking it.
• 4.94-ounce weight at 7.3 x 1.6 x 1.3 inches — Light and slim enough to slip into a hip belt pocket or a jacket pocket for genuinely on-person carry without dedicated storage space.

Best for

International travelers, backpackers, and outdoor enthusiasts who need fast, reliable virus-killing water purification without chemical taste or the weight and bulk of a pump filter. A strong primary purification method for anyone traveling to regions where viral waterborne illness is a real risk and for backcountry users who want the most comprehensive pathogen coverage available.

Compatibility Note

Effective only on clear water. Cloudy or sediment-laden water hinders UV effectiveness. Use the FitsAll prefilter sold separately to clear particulates before treatment in turbid water sources. Includes USB cable, carrying case, and instructions.
