If you live in an area prone to natural disasters, such as hurricanes, floods, tornados, or earthquakes, a water purifier is an essential accessory. These events can disrupt safe water supplies in a number of ways, including electrical shutdowns, water-pipe damage, or bacterial contamination of water lines, all of which have the potential to create ideal environments for microbial growth. Enter the SteriPen Emergency handheld UV water purifier, which utilizes proven UV purification technology to destroy 99.9 percent of bacteria, protozoa, and viruses quickly and effectively. Sturdy and reliable, the SteriPen Emergency purifies 200 half-liter servings of water on just four AA lithium batteries (not included), enough to see your family through any problem period.

The SteriPen Emergency is easy to use, with a design that fits perfectly in commercial water bottles. Just insert the SteriPen Emergency securely into the mouth of the bottle, turn it upside down, and you'll have safe drinking water in less than a minute without having to remove the water from the original bottle. While storing extra bottled water at home is always a good idea, the SteriPen Emergency keeps you from having to stockpile large quantities just in case. Plus, the unit is compact and lightweight, with a body that measures 1.5 by 7.6 by 1.5 inches (W x H x D) and weighs 5.7 ounces. As a result, the SteriPen Emergency fits easily in most emergency kits, or in a side storage closet or desk. A must-have product for people with well-based water supplies or who live in areas with frequent boil alerts, the SteriPen Emergency is among the best forms of safety insurance you can buy.

About UV Purification
The UV water purification method is more than 100 years old, and is currently used to purify drinking water by some of the largest cities in the world, including Seattle, New York, and many others in North America, Europe, and Asia. Several leading bottled water manufacturers also use UV purification to purify their source water. During the UV purification method, the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing the cell enzymes from "reading" its DNA. Without intact DNA, microbes can't reproduce to make you sick. The process is simple but effective, destroying more than 99.9 percent of harmful microorganisms.

Purifying water with UV light offers many advantages. In addition to being safe and effective, UV light does not alter the taste, pH, or other properties of the water, and works without introducing chemicals into the water. SteriPen UV purifiers have also been tested by the Water Quality Association (WQA) against the U.S. EPA Microbiological Water Purifier Standard, and have received the WQA's Gold Seal, signifying that the products purify water safely and effectively.

About Hydro-Photon
Miles Maiden, the founder of Hydro-Photon and a dedicated outdoorsmen, thought there were better ways to purify water in the wild than filters or chemicals. After years of research, he dedicated himself to the development of ultraviolet technology--the same technology used in municipal water treatment plants--for use in a personal, portable device that would provide the user with safe drinking water anywhere. Hydro-Photon received its first SteriPen patent in 1999, followed by patents in 2000 and 2003. In 1999, the first SteriPen was sold through REI, and in 2001 Time magazine named the SteriPen one of the best inventions of the year. The SteriPen's speed, effectiveness, and portability have impressed end users and media alike, leading to profiles in Backpacker magazine and Newsweek and on the Today show as a powerful, user-friendly alternative to pumps, chemicals, and filters.

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 Emergency is the basic SteriPEN model with a red color scheme. 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 Emergency 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.

Reviewer Note: Below I am providing my review of the SteriPEN Traveler Handheld UV Water Purifier because, after using both of these products for several weeks, I have come to the conclusion that they are the EXACT same except for different coloring. SteriPEN's marketing department seems to be trying to brand their pens differently to attract more customers. I don't necessarily fault them for that, but it is confusing.

Original review for the SteriPEN Traveler, same as the SteriPEN Emergency:

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.

I was very doubtful about the steripen. I read the reviews and did research on the product and similar products. When I did buy the pen, I headed out for a back-country camping trip. While I was hiking I noticed several signs that warned about using the water citing an increase in bacterial life. Using the steripen, I was able to drink the water and not get sick at all. After the stint of backcountry camping, I found out why the bacterial life had peaked in the area. A sewage treatment facility had leaked into the water way. That made me feel queasy but I certainly didn't get sick the whole time I was out. I feel comfortable now using the steripen in any situation where microbial life might be of concern.

I already have one of these and have used it for over a year. I purchased this one as a backup and also like to keep them with my katadyn filters. I have the first one on with my rather large Katadyne Pocket filter (not sure what pocket it would fit in) and they both work great, The Pocket is kinda heavy to carry in a backpack.

I purchased the Katadyn Vario for backpacking and this one to go with it. The filters are great to clean up the water, improve taste and remove bacteria, but they dont address most viruses. This UV unit does that and so far I have had no issues in using both for the past few years. I figure you can never be too careful when it comes to your health and if it involves staying healty to survive outdoors, even a better reason to use both.

Good battery life and very well constructed and very sturdy, I have dropped it a few times with the cover on and it has held up fine. Could break if it hits something hard with the cover off so be careful in handling. It is pretty large so very easy to hold onto.
