Just insert Classic 3 in the filter opening, turn the bottle upside down, and gently rock to circulate light throughout bottle. The tapered end also fits snugly in plastic water bottles. Just insert the lamp into the water bottle, turn it upside down and gently rock the bottle.

  • Ergonomic design with a new easy-to-remove twist-off cap.
  • The first SteriPEN to work effectively with alkaline batteries. Can be powered by alkaline, lithium, or NiMH batteries.

    Dear Steripen
    My wife Sally and I leave for India in one month embarking on a fairly intense holiday. We are both heavy water drinkers and wish to take the maximum of precautions on this holiday. Steripen looks to be the answer.

SteriPEN Classic 3 with Pre-Filter is rated 4.3043 out of 5 by 23.
Rated 5 out of 5 by from Great for backpacking and international travel We used the Classic 3 on a recent trip to Peru that involved travel to cities, small towns and two backpacking trips. The device was so convenient and kept us from having to purchase endless plastic bottles of water. We even used it in restaurants and on the train (as discreetly as possible). We have another, lighter model for backpacking but we like the Classic 3 for international travel because the AA batteries can be found anywhere. We used rechargeable batteries and brought a small charger, which worked great.

Rated 5 out of 5 by from SteriPEN has been ESSENTIAL on my backpacking trip I have been backpacking through Asia for a little more than a year from 2014-2015. My trip has taken me through India, Nepal, China, Hong Kong, Macau, and Taiwan so far. During my trip, I used the Adventurer Opti and then transitioned to the Classic 3. SteriPEN has been ESSENTIAL to my travels because I have had access to safe drinking water anywhere, at any time. I almost never had to worry if a store was open for me to buy water or if the purchased bottled water had been re-bottled. The Classic 3 has been my favorite SteriPEN by far. In using rechargeable AAs, I no longer have to search for expensive CR123 batteries that I needed for the Adventurer Opti. It is a fantastic upgrade! Also, as a conservationist, I have significantly reduced my carbon footprint because I don't purchase bottled water much and thus, do not have to contribute to the trash issue in some of these countries.

Rated 4 out of 5 by from Critical That Pins Are Dry It took me 4 years to really read the directions. Usage was very intermittent and frustrating until I carefully dried the two sensor pins between each use. It now works perfectly and customer service was great in trying to fix the two pens I purchased. They really didn't need fixing and it would have been better if customer service had asked me if I had carefully dried the pins before each use. Great device when used properly.

Rated 5 out of 5 by from Great for traveling. Say NO to plastic! We used the SteriPEN Classic 3 every day for 3 weeks on a trip to Peru. It worked great. We used stainless steel Kleen Kanteens and SteriPEN for all of our drinking water and never had to buy a plastic water bottle. The only thing is, be sure to rinse out your bottle regularly and keep the rim clean. When I had the opportunity, I used a little boiling water to sterilize the rim of the Kanteen.

Rated 3 out of 5 by from Good so far I have only used this once while ice fishing on Sylvan Lake. Any one who knows about this lake in central Alberta knows that with all the boat activity on the lake that it is less than ideal for drinking from, very poor water. I had run out of water and got thirsty so tried out the SteriPEN. Worked like a charm. never got sick. Would like to give it a Five star rating but have not used enough to really say. I really like the shape, size and weight of it. Will make an awesome addition to my backpack next trip

Rated 1 out of 5 by from Broke the 1st Day! I bought 2 SteriPEN's. The Emergency and the Classic. Both of them quit working within the 1st week. The retailer wouldn't exchange them, they no longer carry these models and now I'm out $120.00.

Rated 5 out of 5 by from A Life Changing Product! I went on a 16 day hike in the Himalayas (Annapurna) and some days we spent 8 hours on the trail. Thankfully we had a steripen and were able to filter water from passing rivers/waterfalls along the way. It is a life saving and life changing accessory, especially for hikers or anyone who enjoys outdoor sports. It's light, small, and easy to use. I like to travel for months at a time, particularly in third world countries, and I'll never leave home without it. Thank you, steripen!

Rated 5 out of 5 by from Perfect for freezing winter conditions !!! When it's below zero and everything is frozen the SteriPEN works with no worries about a water purifier filter freezing and breaking.

I am planning a trip to Kauai and it has Leptospirosis in the streams. Will this kill it? Do you have an ETA on more classic 3 models with free bottle? Thanks

I have a steri classic 3 that is a couple of years old.  use on one hiking trip.  Going to Cambodia and when I push the button, nothing happens.  the lithium batteries show a full charge.  Do you have any suggestions.  

Asked by: peter
If you are getting no green light from the LED Indicator, you'll want to check the position of the batteries to be sure the two positive tip batteries are in the slots with the + sign and likewise with the negative ends in their - signed slots. Also the position of the battery cap has the small triangular arrow pointing to the lock symbol on the edge of the pen's body. If still no green LED shows when you click the Activation Button you can try cleaning the battery springs and terminal contacts inside the battery compartment and cap with the pink eraser tip on a pencil. If still no LED call us at 888-826-6234, M-F 8:00 - 5:00 eastern. ~ David

Your site says it is out of the SteriPEN Classic 3 with Pre-Filter and bottle, but none of the linked re-sellers carry the bottle that goes with the pre-filter, so where do I buy this whole kit if you don't sell it and it is not available from a reseller?

Asked by: koolerking
Although the Classic 3 is no longer sold in a package that includes a water bottle, the Pre-Filter it comes with is compatible with any Nalgene wide-mouth style bottle. There is also the Fits-All filter, sold separately, that uses the same filtering element and is designed to work with almost any size opening that is commercially available from many manufacturers.~ David

Explain just how this product works, Thank you, Ernie

Asked by: Ernie
Hi Ernie,The quick answer is, SteriPEN products use ultraviolet (UV) light technology to purify water, destroying more than 99.9 percent of bacteria, viruses and protozoan cysts such as giardia and cryptosporidia.Beyond that, UV purification works as the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing cell enzymes from ‘reading’ its DNA. Without intact DNA, microbes can’t reproduce to make you sick.If you'd like to know a bit more of the details and read some very interesting technical reports, you can check out our web site's page: http://www.steripen.com/ultraviolet-light/proven-technology/ Click on the linking stars above: Proven Technology; Proven Effective; Proven Durability and WQA Approved.Purifying water with UV light offers many advantages. In addition to being safe and effective, UV light does not alter the taste, pH, or other properties of the water, and works without the introduction of chemicals to the water.Let us know if you have any further questions, Ernie.~ David

Does this filter remove chlorine taste

Asked by: Retired Gumby
Thanks for your question regarding the possible effect on chlorine taste. Being a chemical, Chlorine would not be treated or removed from the water with the use of a SteriPEN or the Pre-Filter. Our 40 micron filter is designed to remove larger objects from water obtained from a source like a pond or stream where there could be floating dirt, twigs or leaf debris which could block the UV light within the volume of water. The light from the lamp renders the protozoa, bacteria and viruses harmless so that they can not cause the illnesses that would potentially occur from drinking untreated water.I wish I could say that SteriPEN and/or the Pre-filter could get rid of that chlorine taste, but you'll probably need a Carbon Block filter device for that.Regards,~ David

Greetings from India. After I use my Steripen Classic 3 the green light flashes the same way as it does for activation prior to exposing the lamp to water. There is no long green light to signal that it has worked properly after the UV light turns off...?

Asked by: Mandela
Greetings, and thank you for choosing SteriPEN! The lamp should remain on for the complete treatment time and provide an LED notification that the treatment has finished successfully. Please contact our support department at [email protected] or by calling 888-826-6234 and a representative can help you troubleshoot your SteriPEN. They will be able to help you understand whether or not your SteriPEN is malfunctioning.support.steripen.com

After sterilization how long can the water be stored before drinking or is there a certain time limit that you have to consume the water in?

Asked by: Danny
Danny - Many users store water after treatment, however, if you're concerned about the safety of stored water, we recommend re-treating the water before consuming.
