Hi-this is Sue from GE. We are happy to help. The recirculating charcoal filter is included with non-vented models including JNM3161RFSS. The charcoal filter is required for the non-vented exhaust to filter odors. If it was not included, we suggest to contact GE Part & Accessories at 1-877-959-8688 for assistance.
Thanks for checking with us and for choosing GE!
