Continual refinement of the SteriPEN Classic means the current Classic 3 model, when powered by lithium batteries, now treats up to 150 litres of water, has a 90 second treatment time, and a lamp life of 8000 cycles, that’s 8000 litres of water!
Powered by four alkaline, lithium or NiMH batteries, the SteriPEN Classic 3 safely delivers UV light to a glass or bottle of water, reflecting the light throughout the vessel and killing 99.9% of waterborne microorganisms.
Included is the SteriPEN Pre-Filter which removes particulates, the Classic 3 is ideal for wide mouth bottles, and fits securely in water bottle spouts down to 22mm so you can flip the bottle upside down to activate the lamp.
