In order to enjoy your spring-time®420 pro device for a long time, in addition to the semi-annual prefilter change, regular decalcification and disinfection are necessary.

The spring-time® 420 pro combines three different filter systems for water purification:

  • prefilter (activated carbon)
  • reverse osmosis
  • ceramic filter

The prefilter is responsible for "the coarse". It filters dirt and tiny particles out of the water right at the beginning. Over time the prefilter blinds through the trapped particles and therefore must be renewed every 6 months at the latest. You can order the prefilter here:
