What is the investment cost of a sand filter?
The investment cost for a polyester sand filter of 12 m³/h for a swimming pool (48 to 60 m³) amounts to € 550-600. An industrial continuous sand filter of 5 m² or approximately 50m³/h costs around € 50.000. Running costs are very low because of its simplicity and the limited maintenance.
