The VARIO is Katadyn's latest filter pump, which uses ceramic as an impurity filter and glass fiber as a microbiological filter, with less resistance to the pump.

With this model, you can choose between a two-liter-per-minute flow rate and a one-liter-per-minute flow rate to extend the life of the filter. On the other hand, the ceramic washer can be switched to "LONGER LIFE" mode if the water is cloudy, while in "FASTER FLOW" mode, the water flows directly through the fiberglass filter and the pump capacity increases to 2 l/min.

Finally, the presence of replaceable activated carbon granules reduces the chemical content and improves the efficiency.
