My Steripen Adventure: Concerns and Vindication

Good for you to follow through on your "hunch"!!

I hope you got a decent gift card — or at least a reimbursement for postage? :)

Thanks for posting this Travis. I just bought one so time to test it.

How will I for sure know that the lamp is working based on the proper 'brightness?' I have never used one.

David:

I have one that works pretty normal… so hard to say precisely the difference in brightness. Suffice to say, like a mini florescent light tube — you can pretty much tell if the light is working normal — versus a tube that is 'struggling' and dimming like. Maybe Travis can describe the latter in better terms.

Thanks. I have a trip coming up and will take it but some additional Katadyn tabs just to be safe. An extra ounce that I can handle…; )

Since Travis has pictures of a bad one and will be getting a new one, perfect opportunity to show a side by side comparison.

David, that's a tough one to judge. My lamp looked a bit dull and hazy compared to photos I found online. Other than that, there's not much else I can say. I would suspect that the vast majority of units are fine, but every product line has its lemons. Steripen did say they test their units during QC, but I'm not sure if that's every unit or a certain percentage.

I'll try to dig up the photos I took, but I think I deleted them.

Thanks guys.

Thanks for posting that Travis

I've had one for about a year and it seems normal, but now how would I know?

What I hate is that with water treatment there's no way to know if it's working.

Water is usually good, so you're just preventing a rare event of getting some infected water. The fact that I don't get sick could just mean that I didn't happen to encounter any infected water.

And if I did get sick, it's similar to routinely happening intenstinal problems that could be caused by exposure to bad food or fecal contamination. Only rarely does someone get very sick that doesn't go away without treatment.

Oh well, I debate just not treating water so I'm no worse off than that.

O-ring issue

Lamp

Sorry for the sideways photos. iPhone pictures like to do that. The little LED light is supposed to blink during the entire purification process, so some of the light you see in the pictures is coming from that.

Yay – thanks for the pics.

Are those photos from a good lamp or a bad lamp?

This is the bad lamp, and I should be receiving the good one in a few days. Do note that the Steripen Rep said the lamp looked ok from these photos. As I was typing my response to Jerry, I got an email from Steripen:

““““““““““““““`
Travis, it was emitting about half the UV energy we expect. Every pen is tested on a UV radiometer before leaving the factory, so presumably the lamp went bad in the shipment to the store and to you. We keep improving the strength and connections of the lamps, but unfortunately they still fail sometimes.

Richard

After contracting amoebic dysentery (fatal W/O antibiotics) from eating Kinilau – raw fish & veggies – in Cebu, Philippines in Jan. my internal medicine doctor there advise me to use my Steripen even in commercial FILTERED water unless it was distilled water.

I looked strange to the wait staff in restaurants as I stirred my (iceless) water with the Steripen but if you ever had amoebic dysentery you know it is agony and anything you can do to avoid a repeat you'll do. Yeah, don't consume ice in ANY form in 3rd world countries B/C you don't know the source of the water it was made from. Freezing only puts the bugs to sleep. Then they wake up in your nice, warm, dark tummy and go to work multiplying expolentially. And the agony begins…

The Steripen worked flawlessly several times a day for over a month and I'm really glad I had it with me. The lithium batteries held up well and I didn't need the backup batteries.

"I looked strange to the wait staff in restaurants as I stirred my (iceless) water with the Steripen"

But imagine the look on the same wait staff if you had pulled out a First Need pump purifier instead…

Eric, if you don't mind my asking… why is your doctor advising you to zap even commercially filtered water?

Thanks for this thread Travis! I have a new Steripen Opti which is going to undergo some thorough testing soon!

I wonder how we'll know when the bulb is worn out from use if it wears out before the electronic use count tracker thinks it's worn out….

Just wanted to add a note on my customer service experience with SteriPEN. Just today I sent an email
to them to ask for the battery capacity of my Freedom unit (info for another thread in gear forum actually) and got a response back so quickly I didn't even read it at first as I assumed it was an auto-response. Actually it was an answer to my question from Rich Avery. Maybe a slow day or a fluke, but as far as I'm concerned that was stellar customer service.

Andy:

As soon as the visible bulb shorts out, the UV circuity will stop working as well. The visible bulb is the "safety switch" so to speak.

The ultimate would be a self-diagnosing unit that has a built-in UV sensor on a separate circuit that can actually detect if the UV lamp is working at an acceptable level.

And just what is going to check on that UV sensor? :)

I have to say that although I've been very happy with my Steripen and it has worked flawlessly since I stopped using rechargeable batteries (the rechargeables let me down when the temp dropped), that since UV light is invisible, I am always left wondering if I'm just waving a flashlight in my water.

I take the leap of faith that Ben has alluded to, that the Steripen folks have built in safeguards to prevent this but in Travis's case, how would you know if the UV light was failing if the flashlight lamp was still illuminating your steripen?

Good detective work Travis, it would have been easy to assume all was well as long as it was still glowing.

>And just what is going to check on that UV sensor? :)

I was thinking a dedicated global satellite network that constantly monitors the unit's monitoring system. :)

The photos that you posted look like a normal fully functioning unit, but a photo can deceive.

I know you have to be in shade to actually see the bulb on a sunny day. The bulb doesn't give off a lot of visible light, it is the invisible UV that does the job.

From all the experience stories that I have found, the system is more reliable than other systems, short of boiling your water.

The fact that you see the faint white/blue light tells you that it is emitting UV and it doesn't take much UV to do the job.

I don't know what the company thought was defective about it? Or maybe they saw something else and decided to play it safe.

I wonder if the light will look any different when you get the new one?

>I don't know what the company thought was defective about it? Or maybe they saw something else and decided to play it safe.

Because I had a concern and because Steripen would rather play it safe than risk a lawsuit, they offered to actually test my unit. They used a radiometer to see how much UV was coming out of it, and they found it was only emitting 50% of what they expect.

The unit I had may look perfectly normal, I don't know. But I had a pretty strong hunch to really determine if it was operating at full strength, and whether it was luck, karma, or divine intervention, my hunch was correct.

Considering the quality control steps that Steripen takes, I'm not doubting the technology or their product. I happened to get a lemon, and that's the way it goes sometimes. I don't think people should be afraid that their unit is working properly–most likely it is, but if something doesn't seem right, maybe check it out. That goes for any product.

@Travis, That makes sense.

I suspect that even if it was working at 10% it would still do the job, but you paid for 100% and you should get it from a new unit.

I know people out there that use the 1/2 liter timing when they treat 1 liter without issue.

I have no doubt about how well UV works, but silt can block UV and some larger organisms may need more UV in some cases.

I found I really appreciate the Steripen and many people who have hiked with me now use them.

Chemicals may be lighter, but have many disadvantages that can become annoying after many days on the trail. Filters are either too heavy and/or unreliable.
