  • a manifold;

    a filter cartridge removably mounted to the manifold, the filter cartridge comprisinga first cartridge component; and

    a second cartridge component joined to the first cartridge component at a failure interface such that the second cartridge component moves relative to the first cartridge component when the filter cartridge fails, the failure interface comprising a predicted stress concentration area that plastically deforms when the filter cartridge fails while the filter cartridge is mounted to the manifold;

    an RFID tag mounted to the second cartridge component; and

    an MD reader capable of signal communication with the RFID tag, the RFID reader positioned and oriented such that signal communication between the MD tag and the UM reader is interrupted when the filter cartridge fails and the second cartridge component moves relative to the first cartridge component,wherein the second cartridge component and the first cartridge component are joined together at the failure interface such that the second cartridge component is fixed relative to the first cartridge component, the second cartridge component fracturing from the first cartridge component at the failure interface when the filter cartridge fails while the filter cartridge is mounted to the manifold.
