With anywhere from 20 to 50 percent of all travelers becoming affected each class , TD can hit at anytime during or after your trip [ source : U.S. Centers for Disease Control].Escherichia coli(also known asE. Coli ) is the master perpetrator . A bacterial enteropathogen , E. Colican make you very disturbed and can even cause death in extreme caseful . What ’s more , bacterium in build up countries affect 210 million small fry each class and claim the lives of 38,000 of them [ source : Newswise ] .

Now that you ’re terrified to drink the water outside of your place , there is a solution . A machine call the SteriPEN is a contraption designed to sterilise water , making it good to wassail and cook with . resemble a bombastic bottle of nasal consonant spray , SteriPEN is a compact gimmick which uses ultraviolet Light Within to sterilize water supply and make it secure for drinking . So how do these traveling gadgets process , and how do you pick out the most appropriate SteriPEN for your needs ?
In the next section , we ’ll look into the mechanics of how this amazing travel contrivance works .
Mechanics of the SteriPEN
If you break down the SteriPEN ’s name , you essentially have the construct in a nutshell . The SteriPEN has the physical show of a penitentiary and it sterilizes water . That ’s fairly straightforward , right ? But what ’s amazing is how the SteriPEN rids weewee of those pathogens we learned about earlier . The key is ultraviolet luminousness .
Ultraviolet lightis muscularity - fat , electromagnetic energy naturally emitted from the sun . And while it can also have many untoward affects ( this is why we wear sunscreen ) , when innovate to contaminated water system , it put down the power for bacteria and viruses to reproduce . Once the DNA or RNA in virus or bacteria absorbs the UV ignitor , it can no longer procreate , in effect killing the organism and making it harmless to the human body .
The mechanics of the SteriPen are elementary : It has a long , clear wand that fire up up similar to a atomic number 10 or fluorescent fixture tube-shaped structure light . The baton on the end of the SteriPEN ’s body allows the UV sparkle to send into the weewee . Each SteriPEN model works the same way . The small mechanical body create the UV light and the wand captures and disperses it throughout the water . Each SteriPEN has a cleaning cycle and times vary depending on the modelling .
It ’s authoritative to infer that while ultraviolet light sterilizes water ; it does n’t remove bad odors or taste perception as chemicals or carbon filtration would . The best potential solvent for water purification would be a combination of deposit and atom removal followed by carbon filtration and then UV light-headed sterilisation . This gismo wo n’t free your water of any funky smells or coloration . you’re able to use chemical substance and carbon filters for that . But the SteriPEN will kill the bacterium that give you traveller diarrhea such asE. Coliso you wo n’t get wan while you travel .
Now that you understand the mechanics of the SteriPEN , let ’s move on to some of the features and get into how to apply it .

The most effective way to sterilize weewee is to use some sort of particle or deposit filter in colligation with a carbon filter before UV filtering . Of course , the sept who design the SteriPEN knew this , too . That ’s why they pop the question a pre - filter that ’s designed to absent particles as small as four micron in size .
