Product Description

Remove more than 99.9% of viruses, Bacteria, and protozoan cysts from water using only ultraviolet light with the Aqua UV water purifier from SteriPEN. Suitable for hikes, travel, or any situation when pure, drinkable water is not available, this water treatment device uses no chemicals. It won't change the taste or color of the water, or add an unpleasant smell. The unit runs on four AA batteries. A fresh set of disposable lithium batteries will power 150 one-liter treatments; rechargeable nimh batteries will provide 100 treatments, and alkaline batteries will yield 50 treatments. Simply press the on button, place the lamp in your water bottle and stir. In as little as 48 seconds, your water will be drinkable. The lamp automatically shuts off when the treatment is finished. The lamp's lifespan is about 3, 000 treatments. The UV process alone does not Filter particulates, so filtering is recommended if solids are present in the water. The Aqua is compatible with the SteriPEN prefilter and SteriPEN fits all Filter, sold separately. Features: - eliminates over 99.9% of Bacteria, viruses, and protozoa - treats water in as little as 48 seconds - UV lamp provides up to 3, 000 liter water purification - powered by AA lithium disposable, rechargeable nimh or alkaline batteries - up to 150 one-liter treatments or 300 half-liter treatments with lithium batteries.

5.0 out of 5 stars Three trips to the Boundry waters and 60-person days with no side-effects
Reviewed in the United States on August 15, 2017
Verified Purchase
Took it to the Boundry Waters for five days. At least three out of the six of us used it. No problems and no sickness. I have another SteriPen (Explorer I think). Took it to the BWCA twice. No problems and no sickness with that one either. I picked up this one just to have two in-case I busted the lamp on a portage. I read the reviews by the CDC and about how micro organisms are smaller than sediment particles and the size of particles may conceal the organisms, in the shadow of the light. My answer to that is, if it is cloudy water (I always get the cleanest possible) just treat the water twice, if you are really worried.

I purchased this purifier to take to India and used it on all of my water while I was there. I found it was very easy to use on a standard wide-mouth bottle. Unlike some of the other reviewers, I was able to use it okay on a standard wattle bottle when I lost my Nalgene early in the trip and I never got sick. It has not shown any sign of running out of batteries and continues to run strong on my camping trips. I look forward to using it in travel and camping for years to come.

4.0 out of 5 stars Steripen was amazing on a through hike
Reviewed in the United States on August 10, 2019
Verified Purchase
My partner and I used this steripen for through hiking the pct. After 4 months on the trail I cannot image life without it. For ultralight backpacking it is a bit on the bulky and heavy side but it was worth it because I could begin drinking water after 90 seconds.
On a through hike our whole lives revolve around the next water source and at times, especially in the desert, we walk up to a new source thirsty and all we want to do it drink a liter of water. This pen made quick work of that dream.

Now I with all that being said I give it 4 stars because the batteries actually run our fairly quickly. For 2 people we needed a set of batteries for 4 days of use. So if we were going to be on trail more than that we would carry a second set.

I was a little worried by some Steri-pen reviews, but this model had fewer bad reviews. I took one loaded with lithium batteries on a 2.5 week backpacking trip across Thailand. It worked perfectly. I wrapped several layers of plastic bags around it for protection and packed it in the center my backpack surrounded by clothes for cushioning. I never checked the backpack as luggage. You can't fail to protect the glass lamp and then complain if it stops working. I'm a happy customer.

1.0 out of 5 stars I had heard nothing but good things about this and then.....
Reviewed in the United States on October 21, 2020
Verified Purchase
I was so excited to get this after hearing rave reviews from friends. I took it out of the package the day it arrived and tried it at home. It seemed to work. The light came on and turned off as it was supposed to. Took it that weekend on an overnight packing trip and nope, it didn’t work. I could only get the light on if both my fingers were on the metal tabs at the end. Unfortunately, my water bottle did not have a large enough opening for me to hang on to it That way and swirl it in the water. I was very grateful my pack friend had backup filters or I would have been very thirsty. Super disappointed. It was returned as soon as I got home.

5.0 out of 5 stars Great for emergency pack
Reviewed in the United States on February 22, 2016
Verified Purchase
This is a great addition to my emergency gear. I try to get all my battery operated gear in AA versions only, which is what this is. I have the  Goal Zero 41022 Guide 10 Plus Solar Recharging Kit  to recharge my AA batteries. The key to using this is UV light has to have clear water to kill the protozoa, bacteria and viruses. So I also carry coffee filters to clean out the dirt till its clear as possible. Lightweight and small. 4 AA's (I mark the steripen w/ a Sharpie + & - so I can be sure the batteries go in correctly). I zapped some rain water from a bucket. only took about 80-90 seconds. Nice!
