The LifeStraw pocket water filter meets EPA requirements for removal of bacteria and protozoa, according to the manufacturer). It weighs 2 oz, costs $20. Its also available in North America (FINALLY!!)
@TomZentra thanks for your response. so why buy this if it isn't 100%? just asking. Is there a 100 percent or close to it, water filters for a backpacker/ Hiker?
@chitown1966 Water purification requires 3 stages: filtering, virus removal, and taste improvement. You can buy products that do all these things for hikers. Most hikers only filter their water. Using a SteriPEN alone is a bad idea. Without filtering you will drink dead mosquito larvae, animal excrement, and other nasty stuff. Use a charcoal filter to improve taste and remove chemicals, such as petroleum distillates, fertilizer, and insecticides.
@DeimosSaturn Does the company list the types of materials damaged by UV? Also I would imagine that clear bottles would expose the user to some risk. How about DEEP bottles? In a deep bottle are bacteria, etc. exposed close enough to the emitter to kill bacteria. Are there any INDEPENDENT laboratory tests of this device to verify it's claims.
@OliviaSST If you just search wikipedia or google for UV you could probably answer all your questions. And there are independent laboratory tests on this device. However, I still wont buy it. The lamp is made of glass and it sort of like a halogen bulb except it emits UV light. My problem with that is what's so special about the glass bulb that they can't use much more energy efficient, cheaper, and nearly indestructible LEDs?
@DeimosSaturn My point is yes UV light WILL kill organisms, but that is intense exposure to uv light. I have a UV light purification system on the water entering my house as does the Water System in my community. It exposes a very narrow stream of UV light to a VERY high power intense all around dose of UV deriving it's power from a 110volt system using about 300 watts of power. How lil tin batteries do it with a low power emitter in a few mintues is besides me.
BAD. Steripen Journey failed on 1st use on Direct Exum in a day tech climb of Grand Teton. Worked at home when 1st tested, but at 50 deg F it quit after 2 sec into process despite perfectly new, fully-charged batteries. Called company, said they would replace it, but when I showed dissatisfaction that it almost ruined a serious carefully planned trip had I not brought iodine they wouldn't even offer extra batteries, instead accused me of "trying to extort money out of them". Shitty product & Co.
@frontrangea Just had subsequent telephone conversation with Aaron Cox from Steripen and he agreed to test a new unit for me using a refrigerator at cold temps to make sure it will work prior to shipping it. He's also replacing the batteries and including coupons for batteries as well as a mailer for me to send the old one back. I don't think I asked too much of them to go through this trouble, and I'm hopeful that it will all work out. If so I will be a satisfied customer. We'll see.
@frontrangea I'm curious what type of batteries did use? Lithium works best in colder environs. I would suggest you put anything with batteries inside your coat to fully warm up before trying to elicit power from them. That said, I don't trust this technology..seems like too many variables exist to effectively treat the water. How close each organism is able to come to the emitter, for how long, etc. I would want to test it myself by actually putting contaminated water in it and see the res
@OliviaSST I used the stock Energizer Lithium photo batteries... after receiving a new unit from Hydro-Photon, I had the opportunity to test it on a climb of Long's Peak in Colorado. I took it on a subsequent trip to Yosemite and sterilized water at Little Yosemite Valley - neither of the two of us fell ill, so I believe it works. I think the unit has an application for adventurers. I would suggest carrying a back-up set of fresh batteries.
@OliviaSST I also think the technology is trust-worthy, though one must remember to take precautions not to re-contaminate sterilized water with excess water on your containers lid, etc. But for longer trips in the back-country, I will still opt for a water filter as heavy metals, pesticides and other chemicals are finding their way into waters everywhere, and sterilizing obviously does not help.
I was absolutely wrapped with this device for a the first couple of hikes/trips I did with it, but they are reliable yet. My first steripen failed during an extended trip through Morocco. The company replaced it, but the delay cost us a fortune in bottled water.
The replacement unit failed as well partway through a lengthy desert walk in Australia, and left me begging for purification tablets from fellow hikers. The company no longer seemed interested in replying to complaints
@curlsaugogo So basically you're saying it's not reliable for a survival kit, given it's weight, use of batteries, failure rate, etc. A small squirt bottle of bleach is more effective.

what about chemicals? water is sometimes full of harmful chemicals found from factories. Id still boil the water
chitown1966 7 months ago
@chitown1966 Boiling wouldn't remove any chemicals. If you get your water from a clear, swiftly moving stream, it should be fine.

@chitown1966 Boiling won't remove chemicals. You must use a charcoal filter to remove them.

Can you use the steripen for your bladder system that is over one litter?
3318ryan 11 months ago
@3318ryan Most bladders are well over one liter, but it seems like it would work just as well if you multiplied the time by the number of liters.

People should also note that UV radiation actually damages plastics and other synthetic materials so be careful what bottles/canteens you use it on.

how long do the batteries last before needing replaced?

@Christopher711 the website says 100 liters on lithium ion batteries but it's probably less than that.

check out shaneshop (dot) net for the aquastar UV water purifier. It cost less than the steripen and has many advantages.

good vid
but if you took the steripen out like you did too early it flashes red and you have to start the process again i hear.....
