Abstract
A method for predicting the residual useful life of an air filter arrangement is described. The method includes the following steps: providing a plurality of predetermined reference degradation curves; measuring a degradation parameter of the filter arrangement; and estimating the residual useful life of the filter arrangement by comparing the predetermined reference degradation curves and an actual degradation curve defined by measured values of the degradation parameter.
