The pre-filter of the spring-time®420 pro water treatment device consists of two stages:

  • sediment filter
  • activated carbon filter

It should be replaced every 6 months.

Time for changing the pre-filter depends on the quality of your tap water. Highly polluted tap water can lead to shorter time intervals.

The procedure for pre-filter replacement is described step by step in the operating manual for the spring-time®420 pro. You do not need any tools for the change.

The reverse osmosis membrane and the ceramic filter have to be changed only when the conductance of the cleaned water drastically increases (see manual).



  • Change every 6 months
  • Scope of delivery: 1 pre-filter for spring-time®420 pro
