How often do I have to change my pre-filter on the OSMOBIL PRO X?

We are often asked how often the pre-filter on OSMOBIL systems needs to be replaced. We would like to answer this question specifically for the OSMOBIL PRO X:

• Over the service life: After 3 months at the latest, as otherwise the existing filter can rot and damage the membrane in the next step.
• If the water output is too low: If your appliance supplies too little water.
• About the flow rate: After 50,000 liters of water flow.
• In the event of sudden brown discoloration: If well water is used contrary to the specifications, the pre-filter may turn brown within a short time. It should then be replaced immediately. Whether membrane damage can still be prevented depends on the individual case.

The pre-filter costs €15 individually and only €10 in a value pack of 15 pieces. You can find the pre-filter here at a special price: OSMOBIL pre-filter pack for PRO X, PRO & CLASSIC systems 15 pieces
