    I’ve had my SteriPEN Adventurer for several years and done several months of pike packing in the Colorado Rockies and this is the best form of purification I’ve ever used (I grew up in the Colorado mountains and used iodine then pumps in various forms). This is simply lighter and far simpler. I’ve used it in cattle country, after filtering through a bandana, without issue. My one suggestion is to make the shorter time be one click rather than two (which should be the longer time).

      Hi Hilander! Great to hear from you! Just wanted to explain the click order is a safety feature … if a user mistakenly clicks only once, we prefer them to over treat rather than under treat, thus one click indicates one liter in some SteriPEN models. SteriPEN models with LED displays don’t require this safety feature as the user can verify the selected treatment size. Thanks again and please feel free to share your adventures with us at http://www.facebook.com/SteriPEN.

SteriPEN Adventurer Opti is rated 4.25 out of 5 by 40.
Rated 5 out of 5 by from Loyal friend on all my journeys! First time i´ve used SteriPEN during my trip to Malaysia and Thailand and i have to say that it is really great product – I never got sick from the water. Although i know many people who had indigestion, because european people simply are not used to local water, i never had even small digestive problems thanks to SteriPEN! After this fantastic experience i take my SteriPEN as a loyal friend with me to all journeys. During last months i used it on Iceland and Slovenian mountains and i can highly recommend it. Thank you for this amazing product!

Rated 5 out of 5 by from Great Product I have used the Adventurer both personally and for work running the Outdoor Programming for a private school in the northeast U.S. Personally I have used them on trips with my adventure bike to northern Quebec and western U.S. and Canada. Also with work for short trips in the Whites with students as well as multiple expeditions to the Rockies. We always carry more than one and have a backup such as tablets, but have never had to use them. I love the ease of use and dependability. I have had lamps fail, and the customer service has been great and very affordable. Nothing is perfect, but I have had great experience with this product for at least 8 years.

Rated 4 out of 5 by from Great when it works! I have used the device at home and on the trail. It often fails to work initially and I have to look up the flashing light codes to find out what the problem is. Of course this is difficult on the trail and Steripen instructs you to always carry a back up method for purification (tablets for me). On my hike of San Gorgonio peak Monday it did not work. The light went from flashing green to flashing red as soon as I put it in the water, repeatedly. When I got home I found that this was an indication that the water sensors needed to be dried and try again. I also removed the batteries and checked them, fully charged. When I reassembled it, it worked, repeatedly. I did not have tablets on that hike. I hope I don't get the runs.

Rated 2 out of 5 by from Bummed that it stopped working I loved it when I used it last year hiking 1/2 of the John Muir Trail. It worked fine, so fine that I did not bring a back up when we hiked the remainder of the JMT, 136 miles over 10 days this year. Much to our dismay, my steripen stopped working after 3 days even though I tested it before leaving. The green light comes on, blinks and then turns red when putting in water. Interestingly my husband just tested the two batteries now that I am home and they seem to be fine, though the light will not come on. Wished it had worked as I loved it the first trip. And I had only used it for approximately for 47 liters. Not sure what is wrong but I certainly would not rely on this again nor could I recommend it. I purchased it in July 2014 so it is not old nor heavily used.

Rated 5 out of 5 by from Every Ride This device goes with me on every ride here in rural Ohio. This is what my fill up spot looks like. Cool, fresh, and free! Thanks SteriPen!

Rated 4 out of 5 by from Reliable for 1000 miles on the AT I bought my Opti in 2011 and have used it to hike over 1000 miles of the Appalachian Trail. It has always performed in a damp, rough environment with virtually no care, and I've never gotten sick. It does have a few quirks, such as the button can sometimes be hard to press properly, the red and green lights can be hard to see in direct sunlight, and it's best to use it in a clear bottle so you can see it operating -- but once you get used to it, operation is no problem. I'll take the Opti over a filter anytime. I plan to rely on it for another 1000 miles, at least.

Rated 5 out of 5 by from Great product and Exceptional support Day 3 of a 6 day backpack in Glacier and mine quit working for no apparent reason. I generally put a piece of paper across the battery contacts when not using it and the metal plate on the end must have dropped out. Rigged it with a piece of wire I found and it worked fine for the remainder of the trip. Emailed support and they SO NICELY sent me 2 replacement end pieces and spare seals. Wow, what great service, I commend you guys! Thanks so much.

Rated 2 out of 5 by from Meh... Worked great while it worked, a lot nicer than pumping water and or using tablets, however the bulb burned out after a handful of uses. Very disappointing. I was very careful with it and followed all directions, but it died and I had to boil water for a couple days, not a life or death deal. One of my friends used hers for months on a thru hike and long after with no problems, I must have had a bad one.

I see from one of the questions here that the SteriPEN Adventurer has an indefinite shelf life as long as the batteries aren't stored in the device. I've had mine since the summer of 2012 and always leave the batteries inside. Is it still safe to use?

Asked by: DanB
The concern regarding storing any electronic device with batteries installed is that the natural corrosion that can occur will cause the terminals to experience a build up that prohibits the flow of electricity. If the corrosion is fairly minor, it can usually be wiped clean with the pink eraser end of a typical pencil, but in a worse case scenario, this corrosion can actually cause the contact spring(s) to become weakened to the point of breaking. If you have not seen this sort of battery deterioration, (the first stages of which, by the way, are an invisible film,) you are probably alright. If you are getting your Adventurer to turn on and display the LED Indicator next to the Activation Button, everything is fine with the batteries, though they may be somewhat diminished in the level of their charge and how many treatments they will be able to give. As it says in the User's Guide, "when storing Adventurer Opti for prolonged periods, remove batteries to avoid draining them while not in use." ~ David

I have the Steripen Adventurer Opti and have used it for a couple of years now and like it a lot. But, on a recent trip, left the protective lamp cover sitting by the stream and didnt realize until 9 miles later :-) Can I order another cap?

I purchased my Steripen Adventurer opti a few months ago. I just got it out to test it for a trip i have coming up only the water sensor flashed and the green LED, even when submerged. new batteries dont help. am i missing something?

Asked by: RacerRob
Here is a video that demonstrates the proper operating procedure. https://youtu.be/9dB5uv7UVqo If you haven't missed any of the steps, like removing the protective lamp cover first, or waiting for the green blinking Indicator Light, signaling the "Activated Mode", prior to submerging the UV Lamp and water sensor, and if there are no further signals from the LED Indicator, there may be a malfunction with the pen's lamp or circuitry. Pretty rare, but not unheard of. In that case we'd ask you to contact our Technical Support department. Here's our contact information: Hydro-Photon, Inc.

I use a water system in my extended camps that make me need to purify a 6 liter containers that are quite shallow. How will I know treatment time with the Adventurer. Do I just do 6x the 1 liter treatment?

Asked by: Goat Man
The method you will need to use is to treat one liter at a time in a standard 1 liter water bottle and then transfer the water into that larger container. The design of the pen requires that the water being treated is within a specific distance from the lamp for the prescribed amount of time. The larger volume container would not allow for this and may result in microbes not receiving the full germicidal effect of the Ultra Violet light. Happy trails to you! You should be all set to deal with whatever volume you need with this method of transfering one liter at a time, and keep in mind these wise words, quoting our user's guide, "As with any other water treatment system, always have a backup method." ~ David

Hello, I just received my steripen adventurer. the lamp is slightly crooked. Is that normal? It seems to work ok, just wanted to ask.

Asked by: Reggie
Hello Reggie, Although it may not be "normal", a UV lamp that is slightly askew should still function just fine. If the hard plastic, protective lamp cover is not touching the lamp itself when firmly snapped into place, you are probably alright. If, however, it is something that will cause you concern, you are certainly welcome to send it in to our shop for repair or replacement. You are welcome to call tech support at 888-826-6234, Monday through Friday, from 8:00 am to 5:00 pm eastern, to make arrangements. Regards, ~ David

Can these products be used in a Platypus 1L bag?   

Asked by: pa10spro
Greetings, SteriPENs have not been designed in conjunction with Platypus, and if they do work together it is purely coincidental. We are currently developing a larger, portable vessel for rapid purification. We should have some more news in the coming months about its features, but it will purify 2 or 4L volumes of water in about 96 seconds, pretty cool stuff! Thank you for supporting the SteriPEN team!

I have read multiple review where the pen malfunctions.  This is a concern of mine as I am currently using a gravity filter system.  2 questions, which UV product is most dependable and where are the stats for my review of your 99.9% test claim? THX

Asked by: pa10spro
Thank you very much for sharing your concerns with us! SteriPEN does its best to maintain strict quality assurance standards. We would suggest having both the SteriPEN and gravity filter for redundancy. Each have pros and cons and are suited better for particular scenarios. SteriPENs are proven to kill 99.9% of bacteria, viruses, and protozoa, but does not filter hard metals, so your gravity filter would be useful for that aspect of the process. You can visit our testing page at https://www.steripen.com/micro-biological-testing/ to learn more. SteriPEN products have been tested by the Water Quality Association (WQA) against the US EPA Microbiological Water Purifier Standard. SteriPEN has received the WQA’s Gold Seal, certifying that SteriPEN purifies water safely and effectively. More info can be found at: https://www.steripen.com/wqa-gold-seal/

What's the difference between the adventurer and adventurer opti?

Asked by: Rhys
Hi Rhys, Thank you for your excellent question! The standard Adventurer has a different sensing technology than the Opti. The Adventurer Opti uses an optical water sensor vs. a tactile water sensor. It was upgraded because it is generally a more accurate and a better functioning sensor. ~SteriPEN Marketing
