The life bars on the LCD display indicate the life span of the filters. The life bars reduce
gradually through the use of the air cleaner until one or both filters reach the suggested life
span. The life bars will then flash to remind filter replacement.
The suggested life span for the Carbon pre-filter is 1400 hours. The suggested life span
for both the HEPA and VOC removing filter is 2800 hours.
Steps to replace the filters:
1. Turn off the air cleaner by pressing the power button. Then unplug the unit from the
electrical outlet.
2. Firmly press the release buttons on both sides of the front grill and pull the grill outward t
o remove.
3. Replace the old filter (Anti-bacterial HEPA / Activated carbon pre-filter / VOC filter) with a
new one. Note: Arrows face in (toward) the machine and pull tabs face out (toward you)
when replacing filters.
4. Reposition the front grill.
5. Turn the unit back on.
6. Press and hold the filter reset button until the filter life bar resets with a beep sound. The
reminder is reset.
***To prevent mis-operation, the filter reset button is a very small object next to the LCD
display and requires depressing by a pen point or other similar slender items.
Note:
• Make sure to turn off power and unplug the unit before replacing the filters.
• None of the filters are washable.
• All filter polybags must be removed before being installed to the unit.

IMPORTANT SAFETY INSTRUCTIONS
Please read all instructions before using this product. Save these instructions for easy
reference. When using electrical appliances basic precautions should always be
followed to reduce breakage, risk of fire, electric shock and injury to persons including
the following:
● Read all instructions before operating the air cleaner.
● Place the air cleaner where it is not easily knocked over by persons in the household.
● ALWAYS unplug air cleaner when not in use.
● DO NOT use any product with a damaged cord or plug, or if product malfunctions, is
dropped or damaged in any manner.
● Keep the power cord away from heated surfaces.
● DO NOT use air cleaner outdoors.
● NEVER use the air cleaner unless it is fully assembled.
● DO NOT run power cord under carpets and DO NOT cover with throw rugs. Arrange
cord so it will not be tripped over.
● DO NOT use air cleaner where combustible gases or vapors are present.
● DO NOT expose the air cleaner to rain, or use near water, in a bathroom, laundry area
or other damp locations.
● To disconnect air cleaner, first press Power Button to turn air cleaner OFF and remove

● DO NOT allow foreign objects to enter ventilation or exhaust opening, as this may
cause electric shock or damage to the air cleaner.
● Place air cleaner near a power outlet and avoid using an extension cord.
● DO NOT block air outlets or intakes.
● The air cleaner has a polarized plug (one blade is wider than the other). To reduce the
risk of shock, this plug is intended to fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact qualified
personnel to install the proper outlet. DO NOT try to alter the plug in any way.
● A loose fit between the plug and the AC outlet (receptacle) may cause overheating
and distortion of the plug. Contact a qualified electrician to replace loose or worn
receptacles.
● DO NOT sit, stand on, or place heavy objects on the air cleaner.
● ALWAYS disconnect power supply before servicing.
WARNING! To reduce the risk of fire or electric shock, DO NOT use this product with
any solid-state speed control device.

Power ON/OFF button: Press and hold the button for about a second to turn
on/off the air cleaner. Once the unit is on, the built-in air quality sensor will start

speed is 5.
Speed control button (-): Press this button to decrease fan speed. The lowest fan
speed is 1

energy. If the air quality is “Very Poor”, the unit will run at the highest speed to
expedite the air cleaning process.

will reduce fan speed down to 1 (lowest) and both the brightness of the control
buttons and LCD display will dim by 70%. Pressing the sleep
button again or adjusting fan speed under sleep mode will exit sleep mode.
***For energy saving concern and to prolong the product’s life span, asides from
the “Sleep” mode, the control buttons and LCD display will both dim by 70% after
15 seconds of last action. When dimmed, press any key but Sleep button will bring
unit back to full brightness.

control panel. Unit will not respond to any touch control until the control lock is
