Switch off and unplug the machine.

Move the machine to another room.

Plug in and test the machine.

The interface is designed to stay on the screen you select. Please ensure the remote is not being accidentally pressed.

There may be times when the display is showing green but the fan speed is still high.

This is due to the machine always trying to maintain high air quality. For example, in a room with leaky windows, the machine has to work harder via a higher Fan speed to maintain a high air quality.

If you want the fan to be quieter, you can choose to change the airflow direction to face backwards, or turn the machine to manual mode and lower the airspeed.

Night mode is not working

When in Night mode, your machine will automatically sense the ambient light level and adjust the resting screen brightness accordingly.

If the room is bright, (for example, the lights are on), the screen's display will be set to minimum brightness. If the room is dark (lights off) the screen is turned off.

In both scenarios, when the machine is interacted with, the screen brightness will uplift.

The first time your purifier is turned on, the gas sensors will perform a self-calibration which takes one hour after which time they will work normally.

If the power cuts out within the hour, the initialisation period will continue from where it left off.

If your machine is new out the box and has not been turned on for over an hour, please allow a full hour to complete, with your purifier plugged into a secure power source.

Once the full hour has elapsed, turn the machine off and then on again, either with the main power button on the machine, or the remote control.

If your purifier has been plugged into a stable power source for over one hour, and the VOC and/or NO2 screens still do not show, please unplug your machine from the wall, leave for one minute, plug back in, and then turn on using either the main power button, or the button on the remote.
