Q: What are Katadyn BeFree bottles and Steripen UV purifiers used for?
A: Both systems provide safe, clean drinking water while on the trail, traveling, or fishing in remote areas. The Katadyn BeFree uses a physical filter to remove bacteria and protozoa, while the Steripen uses UV light to neutralize microorganisms, offering fast, reliable purification.

Q: How does the Katadyn BeFree water filter work?
A: The BeFree uses a 0.1-micron hollow fiber filter that physically removes harmful organisms such as Giardia and Cryptosporidium. Simply fill the bottle from a freshwater source, squeeze, and drink — no pumping or chemicals required.

Q: What are the advantages of the BeFree system?
A: It’s lightweight, compact, and easy to clean. The collapsible bottle design makes it ideal for backpacking or wading trips, and the fast flow rate means you can hydrate quickly without waiting for tablets or UV treatment.

Q: How does the Steripen UV purifier work?
A: The Steripen uses ultraviolet light to destroy the DNA of bacteria, viruses, and protozoa, preventing them from reproducing. It purifies a full liter of water in under 90 seconds — ideal for travelers and anglers who want safe water without filters or chemicals.
Q: Is UV purification effective on cloudy or sediment-filled water?
A: UV purifiers like the Steripen work best in clear water. If water is cloudy, pre-filter it through a cloth, coffee filter, or sediment screen before using the UV light to ensure full effectiveness.

Q: How long do the filters and UV lamps last?
A: The Katadyn BeFree filter lasts up to 1,000 liters, depending on water quality, and can be cleaned easily by shaking or swishing. Steripen lamps typically last for 8,000 activations, providing years of reliable use.

Q: Do these systems remove chemicals or heavy metals?
A: No. The BeFree and Steripen systems target biological contaminants. For chemical removal or taste improvement, pair them with activated carbon filters or bottled water in areas with known pollution.

Q: Why carry Katadyn and Steripen products at Drift Outfitters?
A: Because safe hydration is essential for anglers and travelers alike. Drift Outfitters carries Katadyn BeFree bottles and Steripen UV purifiers trusted by outdoor professionals for their reliability, simplicity, and lightweight performance.
