OPERATION (continued)
Using the Dimmer Option
The Dimmer Option ( ) allows you to adjust the brightness of the LEDs on the control panel (Fig. 4). You may wish
to adjust the brightness depending on the room where the unit is placed. The unit always turns on with the brightness
on HIGH.
To adjust brightness:
• TAP the Dimmer icon ( ) once to dim the lights to LOW.
• TAP the Dimmer icon ( ) twice and it will shut the lights OFF.
(The air purifier will not shut off).
• TAPPING the Dimmer icon ( ) a third time will return the
brightness to HIGH.
NOTE: The Power ( ) and the Bluetooth ( ) icon will always remain illuminated.
Using the VOC Function:
This HEPA air purifier has a built-in sensor (Fig. 5) that detects when Volatile Organic Compounds (VOCs) are
present in the room air. VOCs are gases that are emitted from certain household cleaning products, home
improvement, and even common home décor products. These gases can be irritating if inhaled. When the VOC
auto sensing mode is selected, the upper left indicator light will illuminate blue and the air purifier will
automatically operate at the appropriate cleaning level to reduce these gases. The lower right indicator will
illuminate green, amber, or red depending on the level of VOCs detected in the room by the sensor.
Green = Low level of VOCs detected, air purifier will
operate on the LOW setting.
Amber = Moderate level of VOCs detected, air
purifier will operate on the MEDIUM
level setting.
Red = High level of VOCs detected, air purifier
will operate in the HIGH setting.
The air purifier will continue to monitor the VOC levels in the
room and adjust the cleaning levels as necessary.
