The Katadyn Hiker replacement element should be replaced after 1150 liters at the latest. The not too small glass fiber fiter surface ensures a particularly fast and good pumping performance (approx. 1 liter/min.) The filter protection, which can be cleaned, ensures additional longevity and the activated carbon improves the taste. The water is safely purified of bacteria, algae, spores, protozoa, sediments and cysts.
