Yeah, It might look clean enough.

I got a new perspective being in a large group of people and hiking and climbing on Rainier. I am like a camel and I seem to keep my fluids inside me. Or I sweat them out. I was amazed how much people pee everywhere. Yeah, that stream at Pebble Creek coming out from the Muir snow field looks like it would be fine to drink from without treating. Not a chance in hell Batman. I saw more people peeing all over the place just a stones throw away from the stream. I am also pretty sure I saw a marmot intentionally peeing and deficating upstream from a Chinese family taking sips directly from it as they took a break from their marmot molestation photo shoots. Payback is a bitch.

Yeah, You need to treat your water.

This steri pen is so quick and easy to use. Are there still some parts per million pee in your water? Sure. But what are you gonna do? I saw pee stains all the way up Rainier and very top is like a volcanic pee trough.

Folks, you are drinking someones or somethings pee one way or the other.

I prefer this one to the classic. Not as big and clumsy feeling.

SteriPEN Opti vs Classic

  • Familiarity: I've put it through the wringer

Battery Life:
I have used the Adventurer Opti all summer long and just had the battery run out on my last trip. I typically use the Adventurer Opti 1 to 2 days a week filtering about 2 liters per day. I would say if you're an avid outdoor junkie who gets out every week than you would only need to replace the battery in the Opti every 2 months. I've used the SteriPEN Classic for about 5 years and the battery life is roughly twice as long when using high quality lithium AA's. SteriPEN has a comparison chart with number of treatments per charge (.5L) but I always do 1L increments due to using a 1L Nalgene. Even in .5L increments the chart does show the Classic having twice the treatment cycles per charge, confirming my real world experience. It shouldn't be a surprise that the Classic has twice as many cycles per charge because the Classic uses 4 AA batteries while the Opti uses only 2 small CR123 batteries.

Durability and Use:
I've used the Classic for 5 years and haven't had a single issue and have only used the Opti for 3 months now. The biggest difference comes in at length and weight. Opti is about 6 1/4 inches long with 4.5oz trail weight (batteries and case). Spare batteries only weigh 1.1 oz because the Opti uses CR123's. The classic comes in at 7 3/4 inches long and 6.6 oz trail weight. Spare batteries weigh 2 oz due to the 4AA's. While the Opti is a little less convienient to use in the field, the weight savings and much smaller design has made me keep coming back to the Opti.

***The extra 20$ for the SteriPEN Adventurer Opti is worth the cost as it retains most of the great features of the classic but in a lighter, more compact design. ***

Does the pen sterilize the cap/ the threads...

Does the pen sterilize the cap/ the threads of a bottle? Do I need to even worry about that? I am use to bleeding the threads using tablets and and worried that I could get nasty bugs if the threads aren't disinfected.

Best Answer Responded on

No it would really only sterilize everything in the actual bottle but, not on threads of the bottle. To be truly safe you would have to find a way to get the "dirty" water in the bottle without spilling into the threads.

Responded on

Good question. Don't get the cap wet, and or rinse off the cap with a bit of sterile water. I suggest using a gatorade bottle, they weigh little, and have a superb cap and large mouth.

I Love this thing

  • Familiarity: I've used it several times

Used this all summer long and never got had an issue with sickness. Much better than pumping. 90 seconds gets you a liter of water. I carry an extra set of extra batteries as a backup but made it through one season without burning up batteries. Its not cheap but the weight and time savings are well worth it In my opinion

Game changer; poor battery design

  • Familiarity: I've put it through the wringer

This thing is a game changer for all my climbing/backpacking expeditions. Lightweight, fast, allows me to carry very little water weight when in areas with water (which are plentiful in the tetons). Only clear flaw is that the batteries are expensive, rare, and you have to take them out of the device after each use to maximize their lifetime as the life is unpredictable. carry an extra set or other purifier for backup. I've needed it.

Responded on

What kind of batteries are you referring to? Thanks!

Responded on

3V Lithium 123. I actually found an affordable package of them on Amazon.

Responded on

They are not rare, or expensive. They are common, and cheap if you buy 10 at a time. Edit your post.

What volume of water can this steri pen...

What volume of water can this steri pen purify at a time? I'm wondering if I can use it to purify my 3 litter camel back bladder...

Responded on

It actually mentions this in the Tech Specs on the left side of the page. It'll purify any volume, just takes longer for larger volumes. At 8 minutes per gallon, a 3L Camelbak bladder should take about 6 minutes to purify.

Responded on

It can in theory...but they don't really recommend it for any type of soft-sided reservoirs or for more than one liter at a time. It's a matter of submersion depth and efficiency. It's only tested and certified for volumes up to 1L.

Responded on

Angus and Phil are both right. You'd basically have to do one liter at a time, presumably with an empty nalgene bottle, dump it in, and repeat. It should take approximately 6 minutes to do it.

Responded on

Phil, and Alexander are wrong.

You can do any size, any volume, if you can swish it around, which you can in one of those silly camelbak bags. Over do it to make sure, batteries are cheap.

Pack batteries!

Inspecting my steripen to figure out why it won't work. Solution: batteries.

That same thing happened to me...good thing I brought chemicals as a backup

Great Device but Bring a Back up

  • Familiarity: I've used it several times

I bought this about 2 years ago and really like it. It does have it's limitations being battery powered though, which is significant because you're talking about your water supply. After a number of uses, the device didn't seem to be able to complete a purification cycle. It would start it, then would give the flashing red signal which means a vague "something is wrong". Later I realized that it just meant that I needed to change the batteries and everything was fine. Great product though. Easy to learn, super light, and so far I haven't gotten sick. So I'm pretty happy.

Don't get caught without batteries

  • Gender: Male
  • Familiarity: I've put it through the wringer

I love this thing now that I know what I am doing with it. It is, however, one of htose things one must read the manual for, then reread to make sure he/she knows how to use the tool on the trail. I did not. I read the manual, tested it, put it in my kit and forgot about it until my next hike. I could not figure out how to work it as recall was abysmal, and the cuing is not so intuitive. Once I relearned to use it, it was a great device. 1 minute for 1 L, 30 seconds for .5 L. Add a nalgene or similarly wide mouthed bottle (A MUST) and you're all set.
The batteries last for many exposures but when the die, they're dead. Again, I didn't learn this until I was on the trail. Probably should have tested it, no? Oops.
Takes 6v batteries, which are rare (dog trainer collars and some cameras?). This is inconvenient. AA or AAA would make this a five star device. That, and instructions printed on the device for dummies like me.

Responded on

I've had the same problem with the batteries. Totally forgot to put spare batteries and didn't realize they were dead because it'll first keep "trying" to do a purication cycle but won't finish. I thought something was wrong with the device. As soon as I got back, I replaced the batteries and worked like a charm again. I agree about the instructions and AA/ AAA would be awesome because then you could use a solar pack with the system.

Small and convenient water treatment

Solid water treatment device. Small and light, great for multi-day hiking trips.

Steripen Rocks!

  • Familiarity: I've used it several times

Makes purifying water that much easier. Lightweight, can double as an emergency backup light (total last minute option), and has not let me down yet, and I've used it in many different places. Only reason I'm giving it four stars is because you have to hold it submerged and stir, and if it barely comes out of the water, you gotta restart. Depending on what the water is in might make it difficult. This was taken in GSMNP:

Best Option

  • Gender: Male
  • Familiarity: I've used it several times

No issues. AWESOME product. THis thing is durable, the battery lasts longer than anticipated and I feel confident in the safety of the water after it's use. I ALWAYS pump my water through an MSR ceramic filter first for precautionary measures.

Converted

  • Familiarity: I've put it through the wringer

I am very weary of backpacking with anything battery dependent, but this thing has converted me. It is nearly weightless yet the casing is really sturdy. It is so easy to use. Super easy. There is a single button, and the light on it lets you know when its done, if it was successful (occasionally it will flash red if you pull it out too early), if the battery is running low, and many other things. And it doubles as a flashlight for rifling through your bag. The only downside is that you have to use a widemouth 1 litre bottle.
The real reason I dropped the money on it is because it doesn't alter the taste and treats everything. I love that I can now drink the amazingly delicious mountain water and know it is safe. Nonetheless, on long backcountry trips I still keep a few iodine tablets in my first aid kit, just in case.

Hassle Free Pure Water

  • Gender: Male
  • Familiarity: I've put it through the wringer

The Steripen is an awesome invention. It is super light compared to pumps and it is just as effective at removing microbes from your water. The batter life lasts a while and it can purify many gallons of water. I highly recommend getting one. Just make sure the silver sensors are submerged when using it: That is what triggers the light.

solid go-to, or an awesome backup unit

let's talk about the pros:
1. the unit is small and light (weighs a total of less than 6 oz with batteries and the separately sold FitsAll Filter)
2. the uv light looks pretty cool when you're using it
3. no need to pump
4. won't leave weird taste

how about the cons
1. it takes over 90 seconds to treat 32 oz of water. If you account for the "pre" filtering using the FitsAll filter, we're talk about ~3 minutes for less than a liter of water.
2. it will have a hard time (or not work) treating murky water. On mostly clear water though, I still use the FitsAll filter.
3. it uses batteries.

With the limitation of no easy way to treat murky water and the time it takes to filter compared to some pump/squeeze type filters, this is my unit of choice only if I know the water source available will provide "clear" water. But weighing less than 6 oz with the FitsAll filter, I haven't found a reason not to carry this as a backup.

Easy to Use

Simple & super easy to use. You won't feel lazy to purify your like how you would with a tough pump. For it's purpose, it works wonders.

Foreign Travel buddy

  • Gender: Male
  • Familiarity: I've put it through the wringer

Over the past 20-months, I've used the SteriPEN in the Peruvian and Ecuadorian Andes with clear water but suspect surroundings. I always carry tablets as a backup due to the reliance on batteries but like the convenience of being able to drink immediately after treatment. In areas with lots of water, that means I carry less water since I don't have to carry an extra liter waiting for chemical treatment to kill everything. You should still rinse bottle threads after treatment, just like with chemicals, and you'll need a wide enough opening to insert the pen. When carrying a water bladder, I leave a pot near the top of my pack. For refills, I fill the pot with a liter of water, treat it with the pen, and then pour that liter into the bladder. For hiking (no pot), I carry a Nalgene bottle. I balance this inconvenience against the wait time with chemicals vs. the weight of a filter.
The visible light (indicating that the UV lamp is on) is difficult to see during the day. If they'd put an indicator light on top of the pen, it would be easier to operate.
I also use the pen while traveling to treat municipal water and reduce the number of bottled waters I would otherwise buy. In short, it is a convenient and reliable foreign travel companion.
