• This product is not intended to filter oil or grease from air.
• Always unplug the power cord from the electrical outlet when the air purifier is not in use or
when changing the filter.
• Never run the air purifier unless it is fully assembled.
• Do not alter the plug in any way.
• Always turn off the air purifier before unplugging the air purifier from outlet.
• Do not place the cord near a heated surface.
• Never operate the air purifier if the plug or cord is damaged or appears damaged. Only
qualified service personnel should ever replace or attempt to replace a damaged power
cord.
• Never use the power cord to pick up, carry, drag, pull, or lift the air purifier. Do not pull the
cord against or around sharp corners and edges.
• Always remove the plug from its power outlet by holding onto the plug itself and pulling
gently.
• Never pull on the cord itself to unplug it from its power outlet.

1.2 Technical data
120V, 60Hz, 90W, 0.8A
1.3 Purifying Process and Main Features
1.3.1 Pre-Filter
Captures larger sized particles like dust. Can be cleaned by vac
uuming lightly or wiping with
a damp cloth. Do not soak in water.
1.3.2 HEPA filter
HEPA filter to remove microscopic particles down to 0.3 microns in size such as fine dust,
smoke, pollen, bacteria and mold.
3
1.3.3 Activated carbon filter
The activated carbon filter consists of a vast system of highly adsorbent molecular sized pores
to
remove gases, light odors and VOC s(volatile organic compounds).
1.3.4 Anion generator
Low level and ozone safe negative ionizer to freshen and balance the air (ie neutralizes a surplus
of positive charges from TV’s and computer monitors).
1.3.5 Air Quality Sensor (AQS)
Measures and displays the air quality. In Auto mode, the unit automatically adjusts its fan
speed based upon the air quality reading. The sensor needs about 10 minutes to warm up to
reach its maximum sensitivity. The display will flash AQS to indicate it is warming up and will
stop flashing and display AQS when ready.
1.4 Placement
In order to get better performance in cleaning, it is recommended to place the purifier on
the ground or a stable surface. Since the air is drawn in through the front of the air purifier it can
be placed near a wall.
2. Function Description
2.1 Standby
In standby mode, the standby indicator illuminates in red to show the air purifier has been plugged
in and has power but is not operating.
2.2 Refresh
Anions are generated under this mode (low level negative ions).
2.3 Fan Speed
There are four different fan speeds with Silent the lowest and Turbo the highest fan speeds.
2.4 Air Quality Indicator
There are five levels of air quality as indicated below:
Note: the air quality reading is located above the “AQS”. Since the air quality sensor is located on
the air purifier the reading will be in the area of the air purifier. In many cases it will have a
reading of Excellent or Very Good.
2.5 Auto
In auto mode, the fan speed of the air purifier will be set automatically based on the air quality
detected by the sensor. We suggest setting the fan speed where you would like it before
pressing Auto. Once pressed, the fan will stay at the same speed but the fan speed display will
reflect the air quality reading as in the table below and not the current fan speed. For example, if
4
you are on the Strong fan speed and the air quality is very good the display on the air purifier will
show Silent even though the fan speed is operating on Strong (speed 3).
The Refresh icon will be illuminated on the panel when the anion feature is activated. You
can turn this off by pressing the Anion button.
In auto mode, the fan will stay on the speed that you select
to run in normal operating mode
but will automatically increase speed when the sensor detects extra particulates in the air.
2.6 Check Filter
When the purifier has run for a total time of 3,000 hours, the maintenance indicator illuminates to
remind the user to check the pre-filter and activated carbon filter. The HEPA filter has a color
shade on the frame to see whether it is time to be replaced.
After maintenance, press “Fan Speed” and “Anion” buttons simultaneously for 3 seconds to reset
the counter. Please note that whenever the “Fan Speed” and “Anion” buttons are pressed at the
same time, the counter will be reset.
If users do not reset the counter after checking the filter or forget to check the filter after 3,000
hours, “Check Filter” will blink after 3,500 hours as a reminder.

The lighted indicator around the power button indicates the fan speed with different colors. Silent
is green, Middle is blue, Strong is orange and Turbo is red.
3.2.3 Refresh
Press this button and the ionizer starts generating anions (negative ions). Press this button again
to turn off. The refresh icon will be illuminated when the anion feature is activated.

4.1.4 Do not use any cleaners or chemicals on the air purifier.
4.2 Sensors
4.2.1 Clean out the dust blocking the sensors’ air inlet
4.2.2 If the sensor is giving a false reading, vacuum around the sensor to remove any dust have
may have accumulated there.
4.3 Filters
The filters should be cleaned or replaced regularly.
Prefilter: It’s washable as normal fabric but DO NOT rinse it. Let it dry flat. It’s recommended to
clean this filter every 3 months and replace it after 1 year.
HEPA filter and Carbon filter: When the purifier has run for 3,000 hours, the maintenance indicator
illuminates to remind the user to check the HEPA and carbon filters. The HEPA filter has a color
shade on the frame to see whether it is necessary to replace. Please replace it when the color is
dark. After maintenance, press “Fan Speed” and “Anion” buttons simultaneously for 3 seconds to
reset the filter replacement indicator.

4.3.1 Disassembly
Using the front cover removal tool, or any non-conductive item such as a plastic utensil, wooden chop
stick
or similar, insert the tool into the uppermost side air intake slot and gently push outwards against the
back surface of the front cover until the top corner of the front panel ‘pops’ free, as shown below.
Repeat this process for the other side and then lift the entire front panel up and away from the main body,
exposing the filter compartment. Place the front panel out of the way and protect it from damage.

NOTE: Any non-conductive implement such as the handle of a plastic utensil, a wooden chopstick or
similar item can be used in place of the tool provided with your unit.
1. Pre-filter: Turn the 4 locks per the direction of the arrows to release the pre-filter.
2. HEPA filter: Hold the small ribbon and pull the filter out.
3. Carbon filter: Hold the small ribbon and pull the filter out.

5. Troubleshooting
Problems Cause Solution
Air Quality indicator

quality.
Lens inside the sensor is
dirty.
Turn off and vacuum the
sensor (to the right of the
power button). Wait a few
seconds and power back
on.
Unit will not turn on. Cover is not fully closed,
may be blocked by filters.
This occurs sometimes in
shipment.
Remove the front cover and
all of the filters. Re-install
the filters and ensure each
