New Water Purifier

“Anybody heard of this? Saw it on paddleing.net

SteriPEN UV Water Purifier”

“a gear thread?
WTF were you thinking about.
it is all about the dummy president wannabes.

man o' man you need to move.”

“Hmmm, somebody else made one of these and it came out about a year or so ago. There was a thread about it, but I can't remember the name.”

“LOL

It uses UV light somehow - they sell a prefilter to go with it too.

Its 150 bucks! yikes! and weighs 8 oz with the FOUR AA batteries that it needs.

I dunno - I still can't give up my Hiker Filter for this. I can buy replacement cartridges for a long time before I've spent that much and the 3 oz diff in weight is ok with me!”

“There's another thread on it somewhere around here. I remember the thing is pretty heavy though, and you can't look at it while you're using it.”

“you can look at this one, according to their web site:

Is UV light dangerous?
Exposure to ultraviolet light can cause skin and eye damage. Used as directed, SteriPEN™ will not cause UV exposure to the user. Note that SteriPEN™’s lamp emits a number of wavelengths, some of which are in the visible range. The visible blue light given off by SteriPEN™ is just that, visible blue light – not ultra violet – and it is not dangerous to look at. In fact while the visible light has no germicidal effect, it is an important indicator that the lamp is functioning properly. If no light is visible the lamp is malfunctioning.

UV-C will not pass through most materials. Drinking containers made from glass, ceramic, metal, and nearly all plastics block UV-C transmission. Also, the underside of the air/water interface in a water container acts as a very effective reflector for UV-C. As a result, when SteriPEN™’s lamp is immersed in virtually any drinking vessel, the UV-C is well contained. Note that SteriPEN™’s water sensors prevent it from operating unless the lamp is completely immersed.

While very few materials are transparent to UV-C, there are a small number of uncommon materials that are. These include optical grade quartz (the SteriPEN™ lamp material) and a few fluoropolymers in the Teflon family – both unlikely materials to be used for drinking containers.

“roam, roam, roam, where have you been? it's old news.

now just think...if you move to CO you're really way back there in the boonies. you won't know a thing and we will not tell you.”

“HUh, this may shorten the life of your plastic containers then, too.”

“the ad i saw said it was "new" and it was to me.

so pooooooooooo on you Gemini!

;)

when ya coming to climb Mt. Harvard?”

“and a few fluoropolymers in the Teflon family – both unlikely materials to be used for drinking containers.


Heh, so I'd better not take one with me to my Dad's company and hang out in the Polymers room!”

“UV for treating water can't be much more harmful than, say, microwaving your food to heat it up...

I've seen aqua-mira used a lot, especially in lower elevations where water is deeper than high atop ridge lines. I still like my Katadyn (Pur) Filter...”

“A UV purifier is useless anywhere the water is cloudy or colored, like in FLorida. Many rivers and watersources here have tannic water, like coffee. Even tastes likt it on a good day.”
