Low humming noise when turned off
Continuous monitoring
The continuous monitoring option is used for air quality, temperature and humidity data to be relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference.
There may be instances when the display shows green, indicating high air quality, but the fan speed is still high. This is due to the machine constantly seeking to maintain a good air quality, and in scenarios such as rooms with leaky windows, the machine must work harder to maintain a good air quality.
This will only happen when the machine is set on auto. To turn off auto mode, please select manual mode, either using the remote control or on the app.
Please check the following on the app:
Swipe up to reveal the setting tab and tap to open options.
Swipe down to find the continuous monitoring option and tap to open.
Turn off the 'collect data when in standby' option. (The icon will turn grey when turned off). Save the change by pressing 'Done' at the top right of the page.
Continuous monitoring can now also be turned on/off by pressing the the 'Auto' button on the remote control for five seconds.
Retest the machine.
