1. A method for verifying sterilization, the method comprising:
performing a sterilization cycle on a sterilizing cabinet having an access port, an interior having at least one tray sized to retain a plurality of medical instruments, and a door having a vent port and a first filter overlying the vent port, the door connected to the sterilizing cabinet and moveable between an open position and a closed position;
opening the door with the first filter overlying the vent port by a single user being non-sterile;
before removing the at least one tray from the interior of the sterilizing cabinet, examining the first filter, by the single user being non-sterile, to verify the integrity of the sterilization cycle in the sterilizing device;
determining if the integrity of the first filter is acceptable by the single user being non-sterile;
removing, by the single user being sterile and gowned, through the access port at least one tray from the interior of the sterilizing cabinet if the integrity of the first filter is acceptable.
