The sure solution for safe drinking water.

Operates on four AA batteries. Purifies 50 liters of water on one set of alkaline batteries or supercharge you Aqua with lithium batteries and you'll treat about 150 liters!

SteriPEN Aqua is the most economical UV water purifier around and since it carries the Water Quality Association’s Gold Seal, you can be sure it is safe and effective. In as little as 48 seconds, SteriPEN Aqua eliminates over 99.9% of bacteria, viruses and protozoa that cause water-borne illness.

Traveling to locations with questionable water quality? Tired of leaving a trail of plastic water bottles?
Concerned about where your family will find safe drinking water if there’s a disaster or boil water advisory?

Save money when traveling by using it to treat tap water rather than purchasing expensive bottled water. Use it in restaurants when visiting areas with questionable water quality. Bring it along on outdoor excursions to avoid carrying water supplies. At home, keep it with emergency supplies so you’ll have the security of knowing you’re prepared if your water supply should be compromised by a disaster or power outage.

SteriPEN Aqua quickly makes water safe to drink in three easy steps:

  1. Press button to activate
  2. Place lamp in water
  3. Stir

It’s that easy! When the treatment is complete, the lamp turns off and an LED indicator lights up so you know you can hydrate safely.

Since Aqua provides 3,000 treatments, you’ll feel secure for years to come.

SteriPEN Aqua is rated 3.6 out of 5 by 5.
Rated 5 out of 5 by from Love my SteriPEN when I'm traveling! I had an old Classic model and used it on many trips to places where I thought the water was too risky. Can't tell you how many times my friends thought I was being over-cautious and then they'd end up stuck in their hotel rooms with the crud while I was enjoying the day. Gave my old Classic to one of those friends and bought a new Aqua! I will never travel without it!

Rated 4 out of 5 by from Great product. So far, so good! I was however a little frustrated that the unit did not work the first time. The instructions are not clear enough about how to install the batteries. On the pen itself, after opening the battery compartment, you see +- in all four positions. I did not have the manual with me nor access to the Internet. So after trial and error, I finally got it right! I was a bit disconcerting.

Rated 3 out of 5 by from Sterip didn't last as long as expected I was traveling in SoAm among hotels and the pen's batteries went far too soon and I couldn't find my new set of batteries. A bit disappointing. Get the plug in if not camping.

We are traveling from USA to Cuba and will only be drinking tap water or bottled water and will use the Steripen aqua to treat that water.  Can I use the Steripen Aqua in hot coffee or tea in restaurants?

Asked by: Judy
The answer is no, and here's why. The Aqua and all the other SteriPEN models are designed to treat clear water. Any coloration will not allow the UV light to penetrate the water, so anything beyond the translucency of weak lemonade is not recommended. Also, the upper temperature limit of the SteriPENs is 120° F (49° C). Hot beverages such as tea, hot chocolate, and coffee are frequently served at temperatures between 160° F (71.1° C) and 185° F (85° C). With these points in mind, if you are able to make your own hot drinks, it is recommended to treat the clear water prior to heating it, which would probably not be the case in most restaurants. Also, the following note is included in an interesting article about boiling water: "According to the Wilderness Medical Society… Water temperatures at 160° F (70° C) kill all pathogens within 30 minutes. Water temperatures above 185° F (85° C) kill all pathogens within a few minutes. So in the time it takes for water to reach the boiling point (212° F or 100° C) all pathogens will be killed, even at high altitude. The moment your drinking water reaches a rolling boil, the water has already become safe to drink."

I have a steripen I got in 2007 when I went to China. Is it still good to use if the light works? Or, how can I be sure it's working?

Asked by: Lori R
Other than the batteries, there is no component of the SteriPEN that would degrade over time. If you are able to see the UV Lamp illuminate, you will be fine using your SteriPEN. As with any electronic device, it is always a good idea to remove the batteries when storing it for an extended period of non-use in order to avoid corrosion. ~ David

Why should I get the classic 3 over the Aqua

Asked by: Care Bear
The higher price of the Classic 3, versus the Aqua, reflects the longer warranty period and the increased number of expected treatments from the UV lamp. There is also the advantage of the SteriPEN Premium Lamp Life Pledge that you get with the Classic 3. https://www.steripen.com/steripen-premium-lamp-life-pledge/ You will notice on the Compare page of our web site ( https://www.steripen.com/compare/ ) that in all other respects, except the color,) they are identical. Currently the Classic 3 comes with a neoprene carrying case and is packaged with our Pre-filter, two features not included with the Aqua. The Classic 3 costs $20.00 more than the Aqua, but, as you can see, you are getting significantly more for your money. ~ David

If I'm looking to treat enough water for a 2L platypus, will treating 1L at a time separately and then combining them be alright? Also, we'll be going 15 days on the Everest base camp trek, do you think the Aqua will hold out alright?

Asked by: Vladweinstein
Yes. You have actually described the recommended method of using the SteriPEN to deal with volumes of water for containers larger than 1 Liter. It does require having a 1 Liter vessel along, but that is the best way to assure that the entire amount will be properly treated. There is another technique for using a pen with a bladder that you can check out at our web site. https://www.steripen.com/stuff/contentmgr/files/1/02ac755595468c5da0c8d224bef3c2db/misc/a_lbladderp248revised9408.pdf . The photos beginning on page 8 show the method of creating a wave motion to circulate the water. It does involve a bladder with a wide mouth nalgene-style opening that is compatible with our Pre-filter, and keep in mind, any nozzle and tube will need to be cleaned and dried to avoid contaminants, no matter which method of treatment is applied. Also, if you keep an eye on our web site in the coming months, there will be information about some new products we are working on that will be of interest to you on this subject. The Aqua will be just fine for the trip you describe. The only difference between it and the other models is the shorter warranty period and the total number of treatments that you can expect from the lamp, 3,000, as opposed to 8,000. In every other respect, it is as rugged as all of the other models. ~ David

Does the steripen kill parasites' eggs like those of pinworm, tape worm, round worm etc...

Asked by: Globetrotter
Thank you for contacting us with your concern. The ultraviolet light of the SteriPEN inactivates a wide range of microorganisms including bacteria, viruses and protozoan cysts. It has not been tested to show an effect on amoeba and the ova and larvae of flat and round worms. At present Hydro-Photon does not have plans to do tests of this nature as they require "animal" testing, which involves severe harm to laboratory host animals. Our company has chosen not to do this sort of testing for parasite evaluation, not due to issues with the parasites themselves, but rather to the host animals needed for the testing procedure. We exclude parasites and their eggs from the list of microorganisms that SteriPEN takes care of, due to our company's policy regarding not wanting to harm laboratory animals in the testing for UV's effectiveness on those microbes.

What is the difference between the Aqua pen and the travel pen please? Do you sent to Australia? Are the batteries standard i.e. can they be replaced in Australia?

Asked by: Sunbird
The Aqua and the Traveler models are very similar, though the Aqua is a newer version that has a few design updates, including a Lamp Cover that is easier to remove, and the ability to use Alkaline batteries. They both use standard AA batteries, but Alkaline will not work well in the older Traveler. Lithium AA will give many more treatments, or you can use AA rechargeable NiMH batteries in either model if you prefer not using disposables. Although we do not send pens overseas through our on-line shop, you can go to this link to find local stores in your area and other worldwide web retailers that are authorized dealers: https://www.steripen.com/locator/ ~ David

What mechanism does the Aqua have to show the level of charge remaining in the batteries, and to indicate whether the charge is sufficient for successful sterilisation?  Is there any difference between the Aqua and the Adventurer Opti in this regard?

Asked by: 0184michael
The Aqua will signal that the batteries are getting low at the completion of a treatment by showing a pattern from its LED Indicators in a rhythm of solid green interrupted by a single red blink. Depending on whether a full 1 liter treatment or a 1/2 liter treatment was administered, the LEDs will either show 2 green simultaneously or just one, respectively. These LED's are clearly labeled on the body of the pen. If the charge is insufficient for a successful treatment the UV light will not come on and the red LED will blink, or the UV lamp will shut off after beginning the treatment and indicate that the dose was not fully administered with that blinking red LED, signaling a weak battery . The Adventurer Opti is very similar, but because it uses only one LED Indicator bulb, the pattern changes depending on if the pen gave a 1 liter or a 1/2 liter treatment. For a full 1 liter, the rhythm is green long blink, red short blink, then a short space of no light, then repeating that pattern, green long, red short, off, etc. For a half liter the pattern is the same without the space, so it would be green long, red short, green long, red short, repeating. The signal for weak batteries is the same as the Aqua, a blinking red LED. These patterns are illustrated in the User Guides that come with the pens or you can access them at this page of our web site: https://www.steripen.com/user-guides/ . You'll just need to click on the appropriate language abbreviation next to the pen you need in the chart. ~ David

I own a Steripen Traveler. (Not the mini.)  This seems to have the same specs as the Traveler.  Is there a difference?

Asked by: Len5742
Thanks for your question regarding the difference between the Aqua and the Traveler models of SteriPENs. The most significant difference is the Aqua can use alkaline batteries in addition to lithium, (though alkaline will get approximately 50 treatments while the lithium will be good for 150,). There is a newly designed twist-off protective lamp cover, making it easier to remove, and the Indicator on the Aqua utilizes three LEDs instead of the one on the Traveler to show the status of the treatment and any trouble shooting signals. The one other difference is the Traveler takes 1 click of the Activation Button for a full liter dose and 2 clicks for a half liter. The Aqua is just the opposite with 1 click for the half and 2 for the full. I hope this helps you understand some of the features that have been upgraded for the new Aqua. Those points also apply to the Classic 3 which, in addition, carries a 3 year warranty/8,000 treatment lamp, with the Premium Lamp Life Pledge, https://www.steripen.com/steripen-premium-lamp-life-pledge/ , as opposed to the 1 year warranty/3,000 treatment lamp and no Pledge of the Aqua. Happy trails! ~ David
