Frequently asked questions

Can I switch off humidification?

Yes. The machine works as a purifier humidifier, or just a purifying fan.

How often should I run a Deep clean cycle?

This depends on the water hardness where you live. The machine prompts you to run the cycle once a month in hard water areas. It prompts you less often in softer water areas. You can select your water hardness with the Dyson Link app.

Will the humidifier overheat if it runs out of water?

No. It has a sensor to detect if it’s out of water. The screen alerts you to refill your water tank when needed.
