Cleaning the machine

The following areas should be checked and cleaned to maintain the machine's performance:

Clean the loop amplifier with a dry or damp cloth.

Clean the Main body with a dry cloth.

Clean the shroud with a dry cloth or soft brush.

When your purifier switches from front to rear airflow there may be a clicking sound as the motor adjusts direction.

This is a normal sound for the purifier to make and is not an indicator of anything wrong with your machine.

Check base

Check around the base of the machine for any debris or obstructions.

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.

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

My display is reading green but the fan is working at high speed

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.

My readings are showing in different colours

The colour of the numbers and readings on the display are linked to the air quality of the respective category.

Green denotes a high air quality, with low pollutants, and red, low air quality with a high amount of pollutants.

Different categories can have different levels of pollutants at the same time, and will therefore display in different colours.
