A method of providing reinforcing of a media pack comprising: forming a media pack having opposed flow faces forming an inlet face and an outlet face, the media pack having a plurality of adjacent layers of fluted filter media forming a plurality of inlet and outlet flutes (114, 122), each layer of fluted filter media including a porous fluted sheet and a facer sheet attached to the porous fluted sheet, wherein forming the media pack further comprises: applying a first seal bead (120, 126) between the fluted sheet and the facer sheet of each layer of fluted filter media closing off flutes formed between the facer sheet and the fluted sheet forming the plurality of inlet flutes or the plurality of outlet flutes; and applying a second seal bead (120, 126) between the fluted sheet and the facer sheet of adjacent layers of the fluted filter media closing off flutes formed between the fluted sheet and the facer sheet of adjacent layers forming the other of the plurality of outlet flutes or the plurality of inlet flutes, the first and second seal beads being axially spaced apart from one another along the flutes; applying a reinforcing agent to the media pack after the media pack is formed, the reinforcing agent being applied in a flowable state, the reinforcing agent being different than the first seal bead and the second seal bead, the first seal bead and the second seal bead having a higher viscosity than the reinforcing agent when applied; and hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack, wherein the inlet flutes have an open end proximate the inlet end and a closed end proximate the outlet end and the outlet flutes have a closed end proximate the inlet end and an open end proximate the outlet end, and the reinforcing agent does not close the open ends of the flutes. forming a media pack having opposed flow faces forming an inlet face and an outlet face, the media pack having a plurality of adjacent layers of fluted filter media forming a plurality of inlet and outlet flutes (114, 122), each layer of fluted filter media including a porous fluted sheet and a facer sheet attached to the porous fluted sheet, wherein forming the media pack further comprises: applying a first seal bead (120, 126) between the fluted sheet and the facer sheet of each layer of fluted filter media closing off flutes formed between the facer sheet and the fluted sheet forming the plurality of inlet flutes or the plurality of outlet flutes; and applying a second seal bead (120, 126) between the fluted sheet and the facer sheet of adjacent layers of the fluted filter media closing off flutes formed between the fluted sheet and the facer sheet of adjacent layers forming the other of the plurality of outlet flutes or the plurality of inlet flutes, the first and second seal beads being axially spaced apart from one another along the flutes; applying a first seal bead (120, 126) between the fluted sheet and the facer sheet of each layer of fluted filter media closing off flutes formed between the facer sheet and the fluted sheet forming the plurality of inlet flutes or the plurality of outlet flutes; and applying a second seal bead (120, 126) between the fluted sheet and the facer sheet of adjacent layers of the fluted filter media closing off flutes formed between the fluted sheet and the facer sheet of adjacent layers forming the other of the plurality of outlet flutes or the plurality of inlet flutes, the first and second seal beads being axially spaced apart from one another along the flutes; applying a reinforcing agent to the media pack after the media pack is formed, the reinforcing agent being applied in a flowable state, the reinforcing agent being different than the first seal bead and the second seal bead, the first seal bead and the second seal bead having a higher viscosity than the reinforcing agent when applied; and hardening the reinforcing agent to form a reinforcing structure to reinforce the media pack, wherein the inlet flutes have an open end proximate the inlet end and a closed end proximate the outlet end and the outlet flutes have a closed end proximate the inlet end and an open end proximate the outlet end, and the reinforcing agent does not close the open ends of the flutes.
