Hello Ray, this is Kelly with Dyson. The PH04 model is a purifier+humidifier. The HP09 is a purifier and heater+fan. If you're looking for something to provide heat in the cooler months, the HP09 would be more effective for you. The PH04 cannot provide any heat. Best wishes, Kelly Dyson Customer Support
Sorry, there was a problem. Please try again later.The Dyson Pure Hot + Cool Link HP04 air purifier is the 4th generation of the Dyson heater + cooling air purifier. As improvements over the HP02, the HP04 has upgraded filters, an increased degree of oscillation, and increased max airflow.
