Apologies for the late reply. The hybrid Panasonic F-YHE15X. It's definitely more effective than the Mitsubishi (MJ-E100DX-H) that I have, but it also chews up significantly more power (off memory maybe 30% more wattage) when the compressor is running. It also has less functionality- you can't set preferred humidity levels like you can on the Mitsubishi, but it does have a sometimes useful warm/cool airflow function whereby you can set it so cool air is directed one way, and warm goes another. Useful if you're spending most your time in one room.Original Post Deleted
