Product Reviews

Rated 5 out of 5 by from First Impression is Good I purchased this UV water purifier for an upcoming trip to South America. I do not yet know how well it will do it's intended job, or how well it will hold up. I have inspected and assessed the unit, and I have tried it out several times. Product Design and Workmanship: I am impressed with the product design, material quality, and build workmanship. It looks like a good, solid and well-engineered product. Operation: At first, I had a bit of trouble with the purification process ending prematurely with LED light showing RED for “loss of detection of water”. After communicating with Katadyn about the issue, I learned that after pressing the start button, you must hold the unit out of the water until the LED begins to flash. Apparently, I was inserting the unit into the water prematurely. Once I used the correct procedure, the problem disappeared. The instructions say: “While the LED flashes, submerge in clear water and stir.” I think those instructions should instead say: “Wait until the LED starts to flash, then insert in clear water and stir”. I purchased a 6-pack of CR123A batteries for a reasonable price online, so I hope I am good for several hundred liters of purified water. Of course, as with any water purifier, it is impossible to know if it really works or not. I have no means to measure microbial contamination to confirm and verify the purifier’s effectiveness. Even if I return from my trip without catching a horrible tropical disease, I will never really know if the purifier worked, or I was just lucky. I will revisit this review after my trip with an update.

Rated 5 out of 5 by from Game changer The steripen is a game changer for back country trips. The weight and size make it a much more convenient option that standard bag and filter water purification. This is especially noticed on back country hunting and fishing trips as I tend to care twice the amount of gear as I would on a regular backpacking trip.

Rated 5 out of 5 by from Simple, lightweight, effective! I now own my second SteriPen. I’ve been using this method of water treatment for years— in the Sierra and the North Cascades. Effective against bacteria, Giardia, Crypto, and even viruses. They make a simple prefilter to remove detritus that might interfere with the UV light, but I often use a clean bandana. UV light is very effective— I am a 35 year public drinking water supply professional, and I swear by this!

Rated 5 out of 5 by from Easy, easy I have had one for years. Used it on many different backcountry trips. Latest use was a month long canoe trip. Need a wide mouth bottle to use. If water has muck in it, filter with a handkerchief. I like that this kills viruses as well. A lot of gravity or manual filters do not. So this is useful in bodies of water that are frequented by humans. Also useful for foreign travel in regions with questionable water sources. I bought this one for my sister but she had already bought one after using mine! I have Sawyer squeeze, Katadyn Be Free, and Katadyn Hiker. They all have their place. But this is my go to 90% of the time.

Rated 5 out of 5 by from Great UV filter Great filter. worked well at 9000 feet to purified water from a creek bordered by cows. Worked perfectly in a Nalgene bottle. Friends had a narrow water bottle and filter did not work.

Rated 4 out of 5 by from Seems well made, but takes too much time. This thing is great, BUT it's only really useful in very specific circumstances. It takes about 96 seconds to sterilize one liter of clear water, double that for slightly turbid water, and is useless if the water is more turbid than lemonade. If the water has large debris, a bandana over the mouth of your bottle is an easy fix for that. A sawyer squeeze will filter 3 liters in 96 seconds, so if you don't need protection from viruses, and odds are you don't, this thing is ridiculously slow. Where it shines is that it is very small and lightweight, so if you have access to clear water along your route, are traveling light, and aren't in a hurry to get anywhere it makes a great choice. iirc ketadyn claims about 50 1L cycles on a set of cr123 batteries, and a spare set for piece of mind weighs very little and takes up almost no space. Is good for what it is, but having actually used it I discovered I'm too impatient to use it as a primary water treatment system. If I do ever travel to where I need virus protection this thing will surely come in handy.

Rated 5 out of 5 by from used backpacking in Morocco I bought this to fight the need to buy multiple plastic waterbottles while backpacking in Morocco (you're not supposed to drink the tap water there). I didn't get sick, so I am assuming it worked as it was supposed to!
