Product Highlights

Allowing you to enjoy safe drinking water anywhere, the SteriPEN Ultra water purifier utilizes UV light to efficiently treat water without any need for chemicals or pumping. A clever LED display makes using the Ultra as simple as can be.

Employing the same technology used to purify water in municipal treatment facilities, hospitals and water-bottling plants, the Ultra destroys viruses, bacteria and cysts, including Giardia and Cryptosporidium, by using high-energy Ultraviolet (UV) light. The Ultra is easy to operate and purifies water quickly and efficiently without the need for chemicals or pumping.

Simply fill a 16-ounce glass, plastic, ceramic or metal container with clear water, push the activation button, dip it in the container and stir slightly to agitate the water. Ultraviolet light is invisible to the human eye, but a visible LED light indicates that the Ultra is working and shuts off as soon as a full dose has been delivered. The Ultraviolet light breaks down the DNA of viruses, bacteria and cysts, rendering them harmless.

NOTE: Because the penetration of UV light can be limited by discoloration, solids and debris, it is important that clear, unfrozen water be used. The SteriPEN FitsAll Filter or Water Bottle Pre-Filter (both sold separately) can be employed to filter particulate-filled water before UV treatment takes place.

The Ultra is powered by a rechargeable battery and a USB cable is included for recharging purposes. The Ultra’s electronics are designed to activate only as long as there is enough battery power available to produce the required UV dosage, so there is no risk of an inadequate dose as batteries run low.

  • . Elkton VA

    Likes: This does everything it's supposed to do as advertized-even makes my tap water taste better. No complaints.

    Dislikes: The charging indicator stays lit when on my iPhone charger, but works just fine when charging on my laptop USB.
