Abstract: A method for estimating a remaining useful life of a filter is provided. The method includes determining, at a processor of a machine, a scaled delta pressure of the filter in the machine based on an input from a plurality of sensors. The method includes determining a plugging parameter of the filter based upon a non-linear relationship between the scaled delta pressure and the plugging parameter of the filter. The method includes estimating the remaining useful life of the filter at a time instant based upon a contamination rate estimate, the contamination rate estimate being determined based upon the determined plugging parameter. The method includes controlling, using a signal, a flow of a fluid entering the filter based on the plugging parameter, and outputting the estimated remaining useful life of the filter on a display.
