Handy for disinfecting clear drinking water 12 April 2011
By Margaret Picky - Published on Amazon.com
Size Name: ONE
Short review:

No method of water treatment is perfect for every situation but for people who will be drinking relatively clean and colorless municipal, well, spring, or bottled water that merely requires disinfection to render microorganisms harmless, the SteriPEN is ideal.

Long Review:

All of the SteriPENs have the same basic mechanism with differences being in form, weight, type of battery, and expected battery life. Some of the models also have LCD readouts. They are sold in different colors and with or without batteries, a storage pouch, filters, etc. The primary difference is between the heavier ones that use four AA batteries and the ones that use two CR123 batteries. The Traveler uses AA batteries.

The SteriPEN website provides charts that compare some of the models to each other, a very extensive FAQ, and user manuals. It is well worth spending some time there before choosing a particular model.

Ultraviolet or UV radiation is invisible but the lamp on the SteriPEN also emits energy in the visible spectrum which appears as bluish light. UV must penetrate the water and reach the microorganism and then go through the cell membrane and body to disrupt the DNA molecules and prevent reproduction. UV does not remove the microorganisms or any particulate matter in the water and it does not affect the way water tastes or smells. UV radiation has only been used in the U.S. to disinfect water since 1916 but sunlight was known to disinfect water in ancient Greece and India and UV is now commonly used in municipal water purification plants.

There are four basic methods of portable water treatment: chemicals, filtration, heat, and ultraviolet radiation. A full comparison is beyond the scope of this review but some of the advantages of the SteriPEN are ease of use, moderate weight, and ability to disable viruses that cause hepatitis, gastroenteritis, polio, SARS, etc. in addition to bacteria and protozoa. It is also easy to use and fast at ninety seconds for a liter and under a minute for a half liter. Ingesting added chemicals is avoided.

Some of the disadvantages with a SteriPEN are that the water needs to be clear and colorless because UV cannot penetrate particles and so it may be necessary to pre-filter. Some water, such as that with heavy coloring of tannic acid from leaves, is unsuitable for this method of treatment. The water must be agitated or stirred while the UV is working. It can only effectively treat up to one liter at a time. The battery cap must be aligned properly for the device to work but it will seal in other positions to prevent accidental activation. The batteries may not work very well at low temperatures or may be depleted and the particular batteries (lithium or NiMH, not alkaline) may be hard to find locally or expensive. The unit may be damaged if dropped. UV may not be effective against parasites. There is no residual effect from the treatment as there is with chemicals.

No method of water treatment is perfect for every situation but for people who will be drinking relatively clean and colorless municipal, well, spring, or bottled water that merely requires disinfection to render microorganisms harmless, the SteriPEN is ideal.

Hard to Really Know~Still Have to Just Trust in Science 23 Mar 2010
By kindred spirit - Published on Amazon.com
Size Name: ONE Vine Customer Review of Free Product ( What's this? )
Well The item operates as it states but you still have to trust the science of the product.And I am okay with that. The green light tells you it is ready and you swirl the pen in the water until the light turns off automatically and then it is safe to drink. The green light will flash again when you stop if the red light flashes then it was done completely.

You should know you cannot use Alkaline batteries with the item. You do get 2- two dollar off coupons that expire in July 2010 for Energizer Ultimate Lithium batteries. I was lucky to already have some rechargable ones here from my old camera.(I did have to charge them) They recommend the rechargeable ones if using in cold climates.

Also the water has to be clear before you use the product. They say even a shirt can be used or a coffee filter. They go to great lengths to say the container must be clean and it will not sterilize droplets on the side of a glass to wipe those away.

Then they say that expensive research has been done to prove it does kill 99.9% of bacteria, viruses, protoza. The statement that gave me a bit of concern is "While carefully controlled microboiological testing of SteriPen has been conducted, use of SteriPen in the field may produce results that vary from our laboratory test data." (ie...you may get sick)

I have a bunch of bottled water that is expired and decided to use it on them and go ahead and drink them. It takes only about 30 second and there is absolutely no leakage when you turn the bottle upside down and swirl it. I am impressed.

All that taken into consideration I would use it to drink clear stream water on a hike if I run out of my bottled water as to drinking it straight. I was a microbiologist for 29yrs so I know the science. We Used UV lights in the TB work room. Our biohazard hoods had UV lights turned on when not in use.

Just keep in mind it is not 100% that you will not get sick. If traveling to a high risk area I'd also take the tablets for the water just to be double sure. Oh you get 200 uses with the lithium batteries.

A good budget-option if you can't afford the Adventurer or the Traveler Mini 15 April 2010
By Scott - Published on Amazon.com
Size Name: ONE Vine Customer Review of Free Product ( What's this? )
SteriPEN is a portable water purification device that uses UV light to purify water found in untreated sources (mainly rivers and lakes) into a drinkable state, killing over 99.9 percent of harmful microorganisms that can lead to illness. This is mainly a concern for people in developing countries and campers/backpackers. As a longtime backpacker, I've dealt with water purification for many years. The most realistic options currently available to me are:

1. Potable water - For the longest time, I just brought in all the drinkable water I would need for a trip and carried it with me. Once I realized how foolish it was to carry the weight of 2-3 gallons worth of water with me in my pack as opposed to 2 liters, I quickly stopped this practice.
2. Boiling - Without a doubt, the best way to purify water is to boil it for three minutes. Of course the problem you run into is that you need a source of heat for this. I don't like wasting my fuel on boiling water when I need it for cooking. And if you are a minimalist backpacker, you don't want to have to lug a cooking system with you just to purify water.
3. Water purification tablets - these mainly use iodine to chemically treat water into a drinkable state. These are great in an emergency because the tablets are so small and filter a large amount of water. I always take these with me just in case. The problem is they take about 4 hours to work and they make your water taste like it came from a swimming pool.
4. Filtration - I have never used a pump filter before, but they have always seemed big and clumsy to me.

The SteriPEN seems like it resolves all these issues because it is small, it is easy to use, and it works very quickly. I recently took out the SteriPEN Traveler Handheld UV Water Purifier with me on two recent trips to the woods and gave it a try. The Traveler is obviously designed for people to take when traveling to developing countries where drinkable water may not be available. I understand SteriPEN's reasoning for it, but it just doesn't seem like there is any necessity for this model. The UV lamp that is used for purification will last 3,000 treatments, which seems like more than enough for the life of the product. Unfortunately, due to the amount of power the UV light uses, the SteriPEN requires lithium batteries which can be very expensive, You'll get 200 16oz treatments off of a set of 4 AA lithium batteries. You can use regular batteries in a pinch but I assume they'll be drained pretty quickly. With the cost of lithium batteries, you are going to pay around 25 cents to treat each gallon of water. The actual SteriPEN is bigger than I thought it would be from the picture. At 7.5" long, it's going to take up some room in your pack or luggage, and it would have been nice if it was about 2-3" shorter. You can buy the SteriPEN Traveler mini Handheld UV Water Purifier or the SteriPEN Adventurer Handheld Water Purifier (the Adventurer and Traveler Mini are the exact same product except for the color scheme!) which is slightly smaller, but I don't understand why they didn't just make the original Traveler that small to begin with.

As to actual use, the SteriPEN traveler works amazingly well. Just hold the UV light in a bottle of water, press the button, and 45 seconds later your water is purified. Now obviously I don't have the ability to actually test the purified water to verify their claims, but the SteriPEN doesn't affect the taste of the water at all, and it appears to work. You also can't use it with really dirty water, as it will not "clean" the water, only purify it. So you're going to want to make sure the water that you use is fairly clean to begin with. But if it is, you can safely drink from it knowing that their are no microorganisms swimming around ready to make you sick.

Overall, even though I was turned off by its size (although it's still smaller than any other purification method other than tablets), the SteriPEN is a very efficient product. My reasoning for only giving it four stars is that I can't see any improvement of the Traveler over the original SteriPEN Classic Handheld Water Purifier. The Classic even has more than twice the lamp life (although it's not like you'd ever need more than 3,000 uses anyway). Why anyone would purchase the Traveler over the Classic is beyond me.

I'm Still Alive and Well! 6 May 2010
By Kindle Customer - Published on Amazon.com
Size Name: ONE Vine Customer Review of Free Product ( What's this? )
As soon as the SteriPEN Traveler Handheld UV Water Purifier arrived I unwrapped it, installed the batteries and ran to the alley behind my house to scoop some feted, brackish water from a pothole.......Just Kidding, but it does beg the question; how do I test this device without spending a week in the bathroom? I often take day-trips to the Fort Collins, Colorado area and go hiking along the Poudre River Trail. Many are the times I have wanted to stop along one of the crystal clear, ice cold, streams and take a huge drink rather than pull on my lukewarm plastic tasting canteen. Last time I did. I read the SteriPEN's instructions carefully before leaving the camping area. I also loaded the Energizer Ultimate Lithium batteries the company suggests (a couple of coupons in the box). I scooped up a bottle of the water, let the pen do its thing, then drank it down. I felt no ill effects afterward and used it on the same trip several more times (three sessions and the batteries did not die).

Now of course there is no way (short of laboratory tests) for me to be sure the water was contaminated in the first place, but there are warnings there about drinking it. As far as I can tell the SteriPEN does what it says it will.

I like it! 20 Jan 2011
By A. French - Published on Amazon.com
Size Name: ONE
I used the steripen on my drinking water for 2 weeks in Nepal. I found it easy to use and carry. I had great results with the Lithium batteries, but tried it with alkaline batts and it worked fine. The only time I got sick on the water there was the one time I didn't use it.
My brother is a pharmaceutical chemist and they use UV light to sterilize all of their equipment in his lab. If it works for a lab it works for me!
-Remember it doesn't get the drops around the neck of the bottles. I would recommend wiping off the neck first.
-I would also recommend the units that take AA batteries. They are easy to find all over the world, but the specialty batteries are rare in undeveloped countries.
