A:Answer Hi there, this is David with Dyson. Night mode will use the machines quieter settings, reducing airflow speeds to range from 1 to 4. Night mode will also dim the display, making it ideal for use while sleeping. That said, you also would have the ability to customize Night mode settings directly within the Dyson Link App, or the included remote control. For example, once night mode has been activated, airflow speed can still be adjusted to whichever setting you prefer. Once you set your fan speed, night mode will continue to function by dimming, and turning off the display. If you experience any issues, or have further questions, please don't hesitate to contact us directly at askdysonus@dysoncom. We're always keen to assist, if ever needed.
Best wishes,
David
