Product Description
Great for travel or an emergency-preparedness kit, this handheld water purifier destroys viruses, bacteria, and common protozoa. It weighs just 8 ounces with four AA, disposable batteries (not included) and purifies 16 ounces of water in 48 seconds, or 32 ounces in 90 seconds. The purifier employs ultraviolet light (UV) to destroy the DNA of microorganisms, making them unable to reproduce and cause illness. It's effective against outdoor microbes like giardia and cryptosporidium; pathogens that cause diarrhea, dysentery, hepatitis, and Legionnaire's Disease; household germs such as bird flu, E. coli, and salmonella; staph and strep; and natural-disaster risks like botulism, cholera, smallpox, and typhoid. No pumping, no chemicals, no test strips, no timekeeping, no lubricating, and no replacement filters are required. All that is required is to push the water purifier's button (once for 32 ounces, twice for 16 ounces), place the pen-like lamp in clear water, and stir until an indicator light turns green. Water has no aftertaste after being purified. Measuring 7.6 inches long, the purifier comes with a nylon case and a user's guide. It exceeds U.S. Environmental Protection Agency guidelines for testing microbiological water purifiers.

 Great product June 28, 2010

I just got back from the Bighorn Mtns and this unit worked perfectly.My Scout Troop had to break into two groups so I had my pen and another leader had his. He had rechargeable batteries, big mistake as they do not work in the pen. Mine purified water for 10 people and was hassle free. I love it!
Works as advertised, can't ask for more June 6, 2010

Bought this for a trip to Belize. It worked well - no stomach problems the whole time I was there. It is easy to use, but definitely use lithium batteries, otherwise you get very few exposures before the batteries die on you. It has a glass bulb, so you want to carry it with you instead of packing it in your luggage. I never had a problem at the security entry points with it, it would pass right through the x-ray machines.
If you are looking for something to give you bacterial/parasite-free water, you can't go wrong with this product. They make a model that is smaller and uses different batterys, but you can find AA batteries anywhere, finding those coin-size batteries in a foreign country could be 'interesting'. sometimes the simplest tools are the best...
Remember that this will treat the water, but does not filter it - paper coffee filters or a fine silk rag work well enough for that.

So far, pleased as punch...4 stars for me. If bulb could be replaced by the user and it were absolutely bulletproof, then I would give it 5 stars. I use mine with 4ea AA Eneloop batteries. Those are the only rechargeable batteries I would buy. With a set of replacement AAs, it's a little bit more of a bundle to schlepp around, but having the AA capability is just fine with me.
For the most part, success with this device is all about reading the directions. Read the directions! Read the DIRECTIONS!!! READ THE DIRECTIONS!!! You have to press the START button for the dosage you want BEFORE YOU INSERT INTO THE WATER you want to treat.!!!!!! Otherwise, IT WILL NOT WORK!!!! I read the instructions when I got it, promptly forgot the sequence, took it into the wilderness without the instructions on a day hike and couldn't get the blasted thing to work!
I had visions of my $70 water purifier being broken, or my Eneloop batteries somehow getting prematurely drained. It was PILOT error! Fortunately, I brought enough water with me but was angry as a hornet when it didn't work. When I got home, studied the directions again, then cut off the English portion and put them in the blue Steripen storage pouch. The directions are also essential to understand the meanings of the various color and flash sequences for the LED.
The specs state two curiosities. First is that it treats 16 oz of water in 48 seconds and 32 oz of water in 90 seconds. Second, the bulb is good for 8000 treatments. The bulb is on for 6 seconds less for a full 32 oz treatment than for two 16 oz treatments. Second, the manufacturer makes no distinction for bulb life with respect to 16 oz or 32 oz treatments. That would lead me to suspect that bulb life is determined by how many starts it is subjected to rather than how long the bulb is in the "on" state. It would seem that you are going to get the best bang for your buck by treating 32 oz of non turbid water at a time. The LED color and flashing sequence will alert you to when you have approximately fewer than 100 treatments left on the bulb. The bulb can be replaced only at the factory. At today's prices, it will cost about $30-$35 which would include your shipping costs both ways.
I also bought the SteriPEN FitsAll Filter. However, in some water sources, even the 4 micron filter is insufficient to filter some of the suspended particles, leaving the water somewhat turbid. The solution is to let the water settle to decrease turbidity or run the water through something like the Katadyn Pocket Water Microfilter before treating with the Steripen. The instructions also provide a procedure for dealing with turbid water, one being to zap the water again depending on turbidity. Doing this will reduce the quantity of water treated over the life of the bulb. Some turbid waters might even be "tea" stained and some color could still get through, no matter what kind of filter you use. Have not run across any flocculating agents that are not combined with a chlorine treatment.
The cap for the Steripen's business end is sturdy and looks to provide adequate protection for the bulb. The Steripen slipped out of its pouch on to a carpeted floor when I retrieved if for this review and there was no harm done. I recommend caution in removing the cap to ensure it doesn't become an inadvertent lever to snap off that bulb. I do this by gripping both the cap and the body of the pen while popping the cap loose with a slight twist, then removing the cap. The cap plus its ventilated neoprene blue pouch would seem to protect it from most knocks in your pack. I am keeping my eye out for a wide mouth container something of the gauge of the standard milk jug, but just big enough to take the Steripen in its pouch as an added measure of protection. Even though the pouch has a velcro belt loop, for me, that is an invitation for a disaster. There is a provision for connecting a lanyard from the Steripen to the pouch if you wear it on your belt.
I would not rely on this as a sole means of providing safe drinking water just because of the battery situation and the potential for the bulb to break. For me, it is a backup system. The Katadyn Pocket Micro is the first line of defense with the Steripen to treat more highly suspect waters. Lastly, I am always prepared to boil. I always choose the clearest water I can find.
Will keep track of see how many 32 oz treatment cycles I can get on one set of fully charged Eneloops and update this review later. As a final note, in some reviews out there, there is confusion on how many times to press the start button for either the 16oz treatment vs the 32 oz treatment. Again this is where reading the instructions is essential. Pressing start button ONCE treats 32, pressing TWICE treats 16. It's counter intuitive I know, but as of 5/11/2010, those are the facts.

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:
The Classic is the basic SteriPEN model. 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 Classic uses AA batteries and fits tightly into water bottles for inversion and agitation.
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.
