SteriPEN Ultra

Great addition to campin gear

used for camping and hunting trips. would recommend.

A must have for a backpacker, hiker, traveler.

I used this product many times during back country camping and hiking trips to purify water in my personal water bottle, while on the trail. it is compact, easy to use, fast acting and performs. For large volumes of water use something like Katadyn Gravity Filter. Because this product is compact and easy to use, hiker with any level of experience can use it. Safe drinking water is a must a successful outdoor adventure.

Best options to make suer clear water is safe to drink. Love it!

Central America approved

So easy to use I thought I’d get sick drinking water out of mountain streams. No issues. Inadvertently had to drink out of a stagnant pond, tadpoles and lots of animal “signs”. No problem.

Great product. I used it several times to purify water with. It works!!!

Perfect for dodgy water

I relied upon a UV pen to treat many liters of water on the Inca Trail hike and in my hostel in Cusco, and neither I nor my companions had any GI issues. I have had the same great results in Mexico and on my tour down the Great Divide Mountain Bike Route. And- it makes a nice gift for adventurers, even children, because it’s simple to use: submerge in relatively clear water, press a button, and stir. I carry extra batteries, but have never had to use them on a trip, and the case gives me confidence that it will survive in my pack.

does not function in cool to cold temperatures

I used this item for a 12 day backpacking trip in the Wind River Range in Wyoming in late August - early September. Although it functioned as expected in warm temperatures, it did not work consistently in temperatures in the 40-60ºF range and not at all in lower temperatures. Even if I stored it in my sleeping bag and jacket pockets and pre-warmed the batteries against my body, the device would immediately cool down and cease to function upon use. This renders the pen worthless in most backcountry contexts. Thankfully I had some trusty AquaMira as a backup, and I resigned to using that most hours of the day.

7 days and NO intestinal issues!

I took this on my recent elk hunt and pulled water continually from streams all week long. NO issues with the squirts or sickness so I feel the pen worked perfectly. No issues with the batteries, size or durability at all!

Easy and compact. Saves me from carrying water weight the bike.
