SteriPEN Freedom is rated 4.363636363636363 out of 5 by 11.
Rated 3 out of 5 by from A purifier with significant limitations. First of all, let me say that this product is works well. It purifies water wherever I am. The huge problem is that it is not "waterproof", the bottom of it is but not fully submersible, meaning while you are purifing water you have to be extremely careful not to drop it in the water! Poor design. The adventure opti has a way better seal then on the freedom. Also, while using the device it does not have a "1 liter feature" so you have to take it out and sometimes shake it after a half of liter to do the rest of the full. Overall this is a sutible purifier for how extreamly light and small it is. But the only thing in my pack I am worried about getting wet is my water purifier, that is a huge let down in my opinion.

Rated 5 out of 5 by from Perfect for S.E. Asia! My wife and I used this SteriPEN for 3 months backpacking S.E. Asia and India. Worked perfectly and never got sick with it. Easy to use, super light and small to pack.

Rated 1 out of 5 by from Won't hold a charge Steripen Freedom won't hold a charge. The first time I used it, it purified about 15 liters (30 cycles) before the battery ran out. The second time, it purified about 5 liters. The third time, one liter. I'm in India, at the beginning of a five-month stay. I typically bring a Steripen Adventurer, which has been reliable, although it purifies 20-30 liters on a set of batteries, not 50 liters as in the specifications. But it has never failed. This trip, I brought the Freedom model to save weight by not carrying batteries. However, it's failed. I wouldn't recommend the Freedom to anyone because it's not reliable.

Rated 5 out of 5 by from Great technology I used the SteriPEN on a recent trip to Peru and it did reassure me psychologically, though the places I stayed with the group (including the Amazon) had bottled water readily available. I'm so impressed with the technology that what I'd really like to know is why this can't be used on a huge scale to help people all over the world get clean drinking water daily? Thank you.

Rated 5 out of 5 by from Peace of mind I had occasion to use my Steripen while in China when supplied water wasn't enough. It makes a great backup, fast and easy to use. Now that I am back at home and as we live in the tropics, this will be my first line of defence when our local water supply fails. We are all far to reliant on our governments water filtration systems, to keep us safe from contaminated drinking water. Our community filtration systems do fail from time to time. We all need to stand up and be more self sufficient. We are fortunate in Australia to have one of the very few reliable, safe supplies of drinking water in the world. We are also subjected to cyclones and other natural forms of disaster, which strike from time to time. Every household should have at least one form of water filtration systems in their emergency kits. This is a good, discrete method of water sterization, which can go with you everywhere, regardless of where you live.

Rated 5 out of 5 by from Backcountry perfection easy to use. easy to charge. super light. I have used the steripen freedom for two years. It has been my primary water treatment method on all of my backcountry excursions in all kinds of conditions. On my first trip using the steripen freedom, my companion used aquamira tablets. We drew water from the same sources, and I observed him using his tablets correctly, yet he came down with a truly horrible case of giardia, and I did not. On long trips, I have used a small (6w) solar charger to keep the battery topped off on my steripen freedom. It draws very little power, and I am able to use the same system to keep my smartphone, headlamp, and steripen fully charged for weeks at a time. I would like to offer two concerns with the caveat that my steripen has always functioned perfectly: One, the flashlight feature on my steripen freedom has accidentally turned on more than once. I am not a fan of this feature, and though my fears have not come true, I still worry that the flashlight LED might drain the battery at a time when I am not able to recharge it. Two, in my backcountry travels, I have met several (4) people who have had experience with their steripens breaking or failing to function well. As I said, mine has always functioned perfectly, but I always carry chlorine tabs in case of emergency.

Rated 4 out of 5 by from Great little guy 2 take travelling, hiking, etc.!! I had the larger "Adventure" model that used 2 CR123 batteries and upgraded to the little "Freedom" for its size, USB charging capability and quickness in water purification! Took it on two Adventure Races (ARs) in May 2015 to replace iodine tablets and not have to wait 30 minutes to drink while racing in the heat of Pennsylvania...first race was 48hrs followed next weekend by a 24hr AR... the Steripen worked great, 40 secs to clean & drink 1L of H2O and off I'd go ;) Also, had enough charge for both races, but the only issue I noticed was my glass tube ended up with moisture in it I'm pretty sure isn't normal? So. I plugged it in for about 5 days and tell moisture disappeared... hence not a full 5 star rating! Dunno Steripen can you tell me what's up with that mysterious moisture???

Rated 5 out of 5 by from Feels great to be free from buying bottled water! I used the freedom on a 6 month rtw trip in 2013. Absolutely no complaints. Heading to India soon, and, after not using it for a long time, plugged it in to charge recently, and am getting a rapid red flash. What does that mean? I tried a cycle in water, and it seems to function normally. Confused and a little paranoid.

I want to replace my Steripen Freedom but would wait to see the new lines if I knew the same lighter weight/size would be available. Can you please advise if yes, or are the new models larger like the rest of the range?

Asked by: LewL
The Freedom will soon have a new, evolutionary model that is exactly the same size and weight. The noticeable difference, besides the name, will be the color of the body, (either blue or camouflage,) and the absence of the flashlight function. Keep an eye on our website for information regarding availability dates, coming up in the very-near-future. ~ David

Is he pre-filter included with the SteriPEN Freedom or is that sold seperately?

Asked by: outdoorgirl8
The SteriPEN Pre-filter is not included with the Freedom model as they are not compatible. It can be purchased separately at https://www.steripen.com/pre-filter/ but because of the shape of the Freedom's lamp base you will need to remove the filter from your water bottle prior to treating the water with the pen. The current models that have the conical base to the lamp, designed to make a seal with the Pre-Filter, and therefore can be inserted to the water bottle with the filter in place, are the Classic 3, Defender, Ultra and Aqua. Older models that have that same base are the Classic, Traveler, Emergency and Journey. ~ David

Hi, I would like to buy a SteriPen Freedom but I've seen that you work on new products. Could you tell me more about the new one, I mean, I need a SteriPen for my next travel (May) and wanted to know what would be the benefit to wait the new one. Thanks

Asked by: Greg
It is a little premature to talk about details regarding the upcoming new models. As you point out, we are always working on improvements, but, you can rest assured, the Freedom model does function very well and its treatment of suspect water is more than perfectly adequate as verified in a whole bunch of test results and technical reports. You can check them out at: https://www.steripen.com/micro-biological-testing/ . SteriPEN products have been tested by the Water Quality Association (WQA) against the US EPA Microbiological Water Purifier Standard, and received the WQA’s Gold Seal, certifying that SteriPEN purifies water safely and effectively. There is really no advantage to waiting for a newer model, but if you should purchase a current model that is replaced eventually by a newer version, we can usually arrange a swap for a nominal upgrade fee. ~ David

I have a steripen freedom and I'm wondering can I purify a 1L bottle full of water if I use 2 cycles of treatment from this 0.5L pen?

Asked by: rrgale
You may treat 1 liter volumes by repeating the 48-second treatment a 2nd time (equaling 96 seconds of total UV exposure time). Freedom’s effectiveness is ONLY tested and certified on volumes up to 1 liter. ~ David

Will the Steripen Freedom fit on a small disposable plastic water bottle that has diameter ~1 inch?  Can you provide the dimensions of the product?

Asked by: andres
The Freedom is designed to be used in wide-mouthed bottles and small glasses of water, (a half liter or less,). Since its water sensors are fairly wide apart and need to be fully submerged in the water for the UV lamp to be illuminated, it will not work in a narrow mouthed, ~ 1 inch bottle, typically the size of store bought water. It is also designed to treat a half liter at a time. One liter volumes can be done by doubling up on the dose to give that 1 Liter a second treatment which would make for a total of just over 90 seconds of UV exposure. The dimensions of the Freedom are 5.1 x 1.4 x .8 in and can be found on our web site at: https://www.steripen.com/freedom/ Regards, ~ David

I just got my stiripen. When I stir it in the water the lamp stays lit for only a few seconds then goes off........ is the lamp supposed to stay on the whole 48 seconds..... Also is it safe to use the stiripen in juice that I get at a market? Thanks!! Liz

Asked by: Elizabeth
Elizabeth - SteriPEN should be used only in clear water. It should not be used in juice or water that has anything added to it, including ice cubes. The lamp should remain on for the complete treatment time. Please contact our support department at [email protected] or by calling 888-826-6234 and a representative can help you troubleshoot your SteriPEN.
