The invention relates to a filter appliance (1) comprising a dilution device, wherein the diluted portion remains largely constant when the entire volume flow is modified. Said filter device is characterised in that the flow characteristic - defined by the pressure loss function .DELTA. pB(VB) - of the constituents of the dilution line B is adapted to the flow characteristic defined by the pressure loss function .DELTA. pA(VA) - of the constituents of the filter line A, in such a way that the dilution condition (I) holds good for at least one diluted portion X where X = VB/VA+VB for volume flows between V1 = 10 l/h and V2 = 120 l/h (first volume flow range) for at least one second volume flow range of at least 5 l/h inside the first volume flow range, .DELTA.PA(VA) designating the pressure drop over the dilution line B according to the respective volume flows VA, VB in [l/min] of the water in lines A and B.
