OPERATION (continued)
Using the Dimmer Option
The Dimmer Option ( ) allows you to adjust the brightness of the LED lights 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 (symbol) and the Bluetooth (symbol) icon will always
remain illuminated.
Using the VOC Function:
TAP the blue VOC Sensor (Fig. 5) for automatic operation
based on VOC (Volatile Organic Compounds) sensed in the
air. When the VOC Sensor mode is selected, the upper left
indicator light will illuminate blue to indicate that the unit
is running in automatic VOC Sensing mode. 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 in the lowest setting, Germ.
Amber = Moderate level of VOCs detected, air purifier
will operate in the medium level setting,
General Clean.
Red = High level of VOCs detected, air purifier
will operate in the Allergen setting.
The air purifier will continue to monitor the VOC levels in the room and adjust the cleaning levels as necessary.
ELECTRONIC FILTER CHANGE REMINDER
This air purifier has two electronic filter check lights to remind you when
to check and replace the True-HEPA Filters and Odor Reducing Pre Filter.
The "Filters" or "Pre-Filter" light will illuminate when the True-HEPA filters
and/or the Pre-Filter needs to be replaced, These indicator lights are based
on the number of hours the air purifier has been in use, and depending on
the environment and contaminants in the area, the filters may need to be
changed before the recommended time.(Fig. 6).
You should periodically check these filters. Depending on operating conditions,
the True-HEPA filters should be replaced every 12 months, and the Odor
Reducing Pre-Filters every 3 months, especially if there have been heavy
odors and particles in the home.
