SteriPEN

Classic 3 Handheld Water Purifier

Essential piece of kit

Works fantastic, absolutely essential. Only reason I gave 4 stars is because I would absolutely recommend getting a rechargeable pen instead of carrying batteries

Easy to use and compact to carry

Great tool for hiking, backpacking, and having for emergency sterilization. At home in case of a loss of domestic water

Works great, easy to use, has held up well so far

I have had this for over six months, used on several camping and hunting trips, great options, especially when there is running water everywhere you are going

Great, simple, functional

Great purifier, light, easy to find AA batteries. Lighter but also larger than my other similar device. Weight is good for the trail

Works great on mountain hunts, It does have some battery issues. The temperatures were 35 over night and i had to take the batteries out and put them back in in the morning

Perfect for the Backcountry

Took this on a backcountry camping trip for 8 days. Our campsite was near a spring, and the Classic 3 allowed us to sterilize our water each day. This was a quick process and gave us peace of mind that any bacteria, viruses, or other organisms were killed prior to our consumption. The issue encountered was the UV lamp would take a couple attempts to fully illuminate in colder weather (40F). Between cold batteries and a cold Classic 3, the device would either fail with a red "X" or say a treatment was successful without the UV light fully illuminating. I found the best action was to warm the batteries and Classic 3 in my pockets prior to use. Once I did that, the Classic 3 worked as expected about 95% of the time. The 5% it didn't work, it would fail for an unknown reason and I'd restart the treatment with success on either the 2nd or 3rd try. Overall, this product worked for my group. In comparison to a hand-pump filter, this Classic 3 was more convenient.

Works great, easy to use, dependable way to get safe water.

A bottle full of Mt Baker lake and a little uv light makes me not get sick, 10/10 would recommend

Great Way to Sterilize Water

Pros: -light weight -easy to use -batteries can be found anywhere -no taste like other methods of sterilization (iodine/ chlorine) Cons: -need to carry spare batteries -takes 90 seconds of stirring I have had this product for a couple years now and it still works great. I've never gotten sick from drinking the water from it. It is really great for backpacking and travel in less developed country. If you use the lithium AA's it really takes forever to run out. However it's always a good idea to have spare batteries.
