## Overview

The KATADYN Steripen Classic 3 uses advanced UV-C light technology to inactivate over 99.9% of harmful microorganisms in clear water. Lightweight and portable at 5.3 ounces, it offers up to 150 activations on lithium batteries and features LED indicators for treatment and battery status.

## Description

Trusted on mountains and trails for over 15 years, the Sterpen Classic 3 is an excellent choice for UV Water Purification. Ultraviolet (UV-C) light rays efficiently purify clear water by inactivating 99.9% of protozoa (including Giardia and Cryptosporidium), bacteria and even viruses. When the treatment is complete, LED indicators flash to let you know that the water is ready to drink. Approximate number of activations using the various battery chemistries: Alkaline (25), Lithium (150) or Rechargeable NiMH (100).

Review: KATADYN Steripen Classic 3 Works Well - Works well. Instructions easy to follow. Size and weight right for travel.
Review: Love the technology, but battery information was misleading - As someone who already owns a lot of NiMH batteries, I wanted to buy this sterilizer over the other version with a built in Li-Ion battery. The user manual said I should be able to get 100 uses out of a set of 4 NiMH’s before needing a recharge, however, once I got the unit, I realized that I could only get 25 uses until the batteries require a recharge. I’ve learned that this unit requires a high discharge rate out of batteries, which NiMH or Alkaline are not great at. Lithium batteries are ideal for high discharge rates (and they are conveniently lighter than 4 AA NiMH’s). I think the only reason to get this version over the lithium ion version, is that this one can accept single use lithium batteries. Single use lithiums can handle extremely high and low temperatures, making them versatile for backpackers who work outside of the ideal working temp ranges of lithium rechargable.

### ⭐⭐⭐⭐⭐ KATADYN Steripen Classic 3 Works Well

### ⭐ It fell apart before I ever used it.
*by R***Z on November 19, 2025*

I purchased this as insurance for a long hike in the Andes of Peru. Fortunately I never needed to use it. I had packaged it with padding inside a water bottle. After the trip was over I removed it from the bottle. I heard strange rattling coming from it. I opened the battery chamber and found loose springs, loose battery contact metal pieces, and loose broken pins that held a round piece in place at the bottom of the battery chamber. The springs were to hold the batteries. Batteries were never installed after I removed them in preparation for the trip. I had purchased too many weeks before the trip to be eligible for return or replacement.
