“Can the air purifier function alone, without the cooling fan or heater operating? Thank you”

1-3 of 3 Answers

• Hello there, this is Kelly with Dyson. The Dyson HP01 Pure Hot + Cool will only purify the air when the machine is turned on, either in hot or cool mode. The air gets purified when it passes through the HEPA filter, and is then expelled in to the air via the amplifier loop. To have the air purified, you will need to have the unit on, even in the lowest speed setting of 1. Best wishes, Kelly Dyson Customer Support

• the short answer: No There is no purification only mode although, you can run the fan at the lowest setting and it will make little noise and a very slow gust of wind output while still filtering the air.
