The smallest, lightest SteriPEN®, the AdventurerOpti Water Purifier uses a revolutionary optical eye to sense the water. The patent-pending technology provides safe use and the standard insulating sleeve around the UV lamp allows purification in even the coldest of waters. Fast, light, easy and effective, the AdventurerOpti provides the ultimate protection from waterborne illnesses. Giardia, cryptosporidium, bacteria and viruses are all destroyed in seconds-by SteriPEN® UV light. The UV lamp provides up to 8,000 one-liter treatments. UV purification works as the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing cell enzymes from 'reading' its DNA. Without intact DNA, microbes can't reproduce to make you sick. The process is simple but effective, destroying over 99.9 percent of harmful microorganisms. Great for camping, hiking and backpacking.
  • The SteriPEN Adventure Opti system uses UV light rays instead of chemicals to purify water for drinking.
  • Ultraviolet light destroys 99.99% of protozoa (including Giardia and Cryptosporidia), bacteria and viruses.
  • The AdventurerOpti purifies 0.5 L (16 oz.) in 48 seconds and 1.0L (32 oz.) in just 90 seconds.
  • The optical water sensor detects if the purifier is in water allowing the UV light to activate when the SteriPEN is immersed.
  • The optical water sensor doubles as a handy LED flashlight when you need water at night.
  • Easy to use 1 button operation; LED light quickly indicates when ready to purify, then place the pen like lamp in clear water and stir until indicator light turns green.
  • Dirty water should be pre filtered until clear prior to treatment.
  • The UV lamp provides up to 8,000 one liter treatments.
  • Device works with containers with minimum 1.75 in. diameter opening (ie Nalgene wide-mouth bottles).
  • Low power indicator lets you know when batteries need replacing.
  • Automatic shut off when treatment is complete.
  • Includes black neoprene case with belt loop and 2 non-rechargeable CR123 batteries and instructions.
  • Size: 15.5cm. (6.1in.) x 3.3cm. (1.5in.) x 2.2cm. (1.0in.)
  • Weight: 103g/3.6 oz. with batteries

      Nice little filtration device but won't work when temperature gets very low. Have to keep it in your pants pocket so the battery stays warm.

        This is now part of my backpacking winter kit. Very easy to use with gloves, aids in keeping fingers dry, no more frozen filters. Slip it into a torso pocket to keep the batteries warm.

                    Actually I bought this as a present a few months ago because it was on a gift registry. The groom knew of it as he writes for an outdoor clothing company. He swears by it and has had it long enough for me to know he hasn't gotten sick. This time I purchased it as a gift for my husband's son who is a wildlife biologist. Well, he already has one and thinks it's great. I will be keeping this because it is good to have when the unexpected happens. Haven't used it myself but my husband's son said it is so easy and fast to get rid of bacteria in the water that you really don't believe it has done anything and he usually zaps things longer than recommended just to be sure. Since an "avid adventurer" and an "environmentalist" recommend this product I would say it is a good bet to do what it says it will do.

                        We decided to try this on a hiking trip in New Hampshire. When it came we tested it at home and it worked fine. When we got on our trip it did not work. It appears the batteries did not work or died. Of course it uses some obscure battery other than AA or AAA so we did not have a replacement. We were left high and dry and reduced to boiling water with the JetBoil. The idea is great but you are probably better off with a manual pump. At least you know that it works.

                        Took this device to Kathmandu. It appeared to work as directed, but I got diarrhea almost immediately.

                        After about a week, it rolled from my pocket as I lay down in its protective case with the cap on. It fell about 1 foot to a carpet. It never worked again.

                        Has any third party ever tested this device and found it effective?

                        Should such a fragile device be sold as outdoor gear?

                        Sorry I wasted my money

                          I keep one in every emergency bag I have (work, car & home). Best to filter water first (I use the fits all filter) then use this to kill anything that gets thru the filter. Much quicker than boiling water and no nasty taste from chemicals. Awesome product!

                              A pre-filter should be used to remove the larger sediment from the water. This makes the steri-pen function more effectively.

                              The SteriPen Adventurer Opti Water Purifier does not come with a water bottle.
