Product Description

SteriPEN is the world's leading manufacturer of ultraviolet, handheld water purifiers. SteriPEN purifiers quickly and easily make safe drinking water available for travel, outdoor recreation, and emergency situations at a fraction of the cost of bottled water. SteriPEN Traveler’s ultraviolet (UV) lamp destroys over 99.9 percent of harmful microorganisms in water. UV purification works as the cells of microbes absorb ultraviolet energy emitted by the lamp so they can't reproduce to make you sick. Great for travel to areas with risky water but keep it handy for emergencies and outdoor adventures. Easy-to-use 1-button operation. Place the lamp in clear water and stir. LED indicator shows treatment and device status. Purify a half-liter in 48 seconds or a liter in 90 seconds. Lamp automatically shuts off when treatment is complete. Unclear water should be pre-filtered prior to treatment. Includes water sensors safety feature so the UV light only turns on when safely below water surface. The UV lamp provides up to 3,000 one-liter treatments. Powered by four AA lithium or NiMH rechargeable batteries (not included). Designed to fit snugly in plastic water bottles or can be used in wide-mouth bottles or glasses. Can be used with SteriPEN Pre-Filter or FitsAll filter accessories. Comes with instructions and 1-year limited manufacturers warranty.

Well The item operates as it states but you still have to trust the science of the product.

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.

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.

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.
