Abstract: A method for estimating a remaining useful life of an air filter. The method includes determining, at a controller of a machine, a delta pressure of the air filter in the machine based on an input from a plurality of sensors. The method includes determining a percent plugged of the filter based upon a non-linear relationship between the delta pressure and the percent plugged of the air filter. The method includes estimating the remaining useful life of the filter based upon the percent plugged.

Abstract: Disclosed are various exemplary embodiments of an air filter element for a machine. The air filter element may include a generally rectangular body with a rounded bottom surface, where the generally rectangular body may be configured to be inserted into a filter housing in a first direction. The filter element may also include an inlet opening at a top surface opposite to the bottom surface of the generally rectangular body, where the inlet opening may face in a direction substantially perpendicular to the first direction. The filter element may also include a front surface facing substantially in the first direction and defining a discharge opening and a rear surface opposite to the front surface of the generally rectangular body. The filter element may further include a sealing element disposed on a side surface of the generally rectangular body between the front surface and the rear surface, such that the sealing element substantially may seal off a gap between the side surface of the filter housing and the generally rectangular body when the generally rectangular body is inserted into the filter housing.
