UV Portable Water Purifier
|
Ultraviolet portable water purifiers destroy bacteria, viruses, and other microorganisms that can cause serious illness if one drinks a contaminated water or uses it to prepare food.
Infants are particularly susceptible, making it necessary to have a clean, safe source of water for preparing their food or formula.
Of course, purifying water is not always an easy task. Boiling will kill microorganisms, but you must be able to bring the water to a boil, and then continue the boil long enough for it to work.
Because of limited access to containers or heat sources, such as a fire or stove, boiling is not always an option and that's where UV travel water purifiers come to rescue.
How Ultraviolet Portable Water Purifiers Work
A UV portable water purifier uses ultraviolet light to destroy microorganisms in the water. Water is collected in a container, and then the battery-powered purifier is placed in the water.
The purifier has a lamp that emits ultraviolet light for a specific amount of time, cleansing the water of microorganisms. When the cleansing cycle is complete, an LED light on the purifier will flash.
Recommended UV Portable Water Purifiers
The most popular model is the SteriPEN. The SteriPEN is only 6.1 inches long, and weighs only 3.6 ounces, so it is easy to stow in a backpack, suitcase or overnight bag.In addition to being extremely portable, the SteriPEN is a fast purification method, able to purify 32 ounces of water in just 90 seconds. Because it is a UV purifier, there are no chemicals or test strips, and the water has no chemical aftertaste.
The SteriPEN is also an extremely effective travel water purifier. Despite its small size, it destroys 99.99 percent of viruses and bacteria in the water.
It also exceeds the U.S. EPA standards for water purification, and has received exceptional reviews from users for its durability.
Drawbacks
 |
Ultraviolet light does not destroy chemical contaminants, so some water will not be purified enough for drinking.
If you know that the water may contain chemical contaminants, take a second method of purification along.
Ultraviolet travel water purifiers also do not destroy particles in the water. Water that is muddy or has solid particles in it will need to be filtered before it can be purified.
For those who need water purifiers in areas where this is a regular problem, there are UV water purifiers available with an accompanying filter. Water passes through the filtration system before going into the purification system. While those purifiers are naturally bulkier than models like the SteriPEN, they may be necessary for some users.
Finally, UV portable water purifiers use a lamp and require batteries. The UV lamp in less durable models may break or become damaged if the purifier is dropped or banged, in which case the purifier will no longer work.
In addition, batteries are required to operate the lamp. While batteries typically allow users to filter as much as 500 gallons, depending on the purifier model, they will eventually need to be changed.
Users should check the batteries in their ultraviolet portable water purifier before leaving, and should always carry extra batteries.
UV portable water purifiers can be an excellent way to ensure that safe, clean drinking water is always readily available. While there are some drawbacks to using them, those are not major obstacles and can be easily overcome with simple pre-planning.
