Total filtration is defined as the sum of inherent filtration and added filtration.

Explanation:
Total filtration is the combined effect of all filtration in the beam path. It includes inherent filtration, which comes from the tube’s own components (glass envelope, insulating oil, housing), plus any added filtration placed in the beam (usually aluminum filters). Because filtration adds up, the total filtration is the sum of inherent and added filtration, typically expressed as millimeters of aluminum equivalence. This total determines the beam’s quality (HVL) and the patient dose: more filtration hardens the beam, reducing skin dose and improving image quality. So, the statement is true.
