Abstract: An air filter assembly having a primary filter element, a secondary filter element, and a housing with an outlet tube is disclosed. The primary filter element is operably installed within the housing and has an interior volume. The secondary filter element is operably installed within the primary filter element interior volume and has an interior volume defined by a first wall extending between a closed end cap and an opposite open end cap. The open end cap of the secondary filter element defines a sealing structure having a first portion extending into the secondary filter interior volume. The outlet tube is operably connected to the housing air outlet opening and includes an inset collar being at least partially disposed within the secondary filter interior volume and extending over at least a part of the sealing structure first portion.
