Steripen Classic 3 UV Water Purifier with 40 Micron Pre Filter Pack 60110058

Ultraviolet (UV-C) light rays sterilize clear water by eliminating 99.9% protozoa (including Giardia and cryptosporidia), bacteria and even viruses. The water can be drunk as soon as the smiley lights up and the treatment has been successful. Use only in clear water, as cloudy, sediment-containing water affects its effectiveness. The pre-filter fits perfectly on 1L wide-mouth bottles and filters dirt particles out of the water, which could impair the effectiveness of UV light. The pre-filter is screwed directly onto the wide-mouth bottle and the Steripen is inserted into the pre-filter. Turn the bottle upside down and rock gently so that the UV light can circulate in it. The optimized LED display informs you about the treatment volume and the condition of the batteries and the UV lamp. 4x AA batteries are not included; Weight: 180g; Dimensions: 18.6 x 4.3 x 4.3cm
