3 Follow the steps 3-4 in “Setting up the Wi-Fi connection for the rst time” section.
4 Using the air purifier
Understanding the air quality light
The air quality light automatically goes
on when the air purier is switched on,
and lights up all colors in sequence. After
approximately 30 seconds, the particle
sensor selects the color that corresponds
to the surrounding air quality of airborne
particles.
The color of the air quality light is
determined by the highest risk index among PM2.5, IAI and Gas readings.
PM2.5
AeraSense sensing technology accurately
detects and quickly responds to even the
slightest particle change in the air. It provides
you with reassurance with real-time PM2.5
feedback.
Most of the indoor air pollutants fall under
PM2.5 – which refers to airborne particle
pollutants smaller than 2.5 micrometers. Common indoor sources of ne particles are
tobacco smoke, cooking, burning candles. Some airborne bacteria and the smallest mold
spores, pet allergen and dust mite allergen particles also fall under PM2.5.

IAI
The professional-grade AeraSense sensor detects
the level of indoor air allergen and with numerical
feedback from 1 to 12 the potential risk level of
indoor air allergens can be displayed. 1 indicates
best air quality.
GAS
With an advanced gas sensor, a display ranging from
L1 to L4 shows the level change of potential harmful
gases (incl. VOC, odor, etc.) detected. L1 indicates best
air quality.
Turning on and o
Note:
• For optimum purication performance, close doors and windows.
• Keep curtains away from the air inlet or air outlet.

the screen.
»After measuring the air quality, the air purier automatically switches to the display
which has the highest readings among PM2.5, IAI and Gas (g h).
3 Touch and hold the button for 3 seconds to switch o the air purier.

7 Troubleshooting
This chapter summarizes the most common problems you could encounter with the
appliance. If you are unable to solve the problem with the information below, contact the
Consumer Care Center in your country.
Problem Possible solution
The appliance does
not work even though
it is plugged in.
• The lter replacement alert has been on continuously but you
have not replaced the corresponding lter. As a result, the
appliance is now locked. In this case, replace the lter and long
press to reset the lter lifetime counter.
The airow that
comes out of the air
outlet is signicantly
weaker than before.
• The surface of the lter is dirty. Clean the surface of the lter (see
the chapter “Cleaning and maintenance”).

14 EN
Problem Possible solution
The air quality does
not improve, even
though the appliance
has been operating
for a long time.
• Check if the packing material is removed from the lter.
• The lter has not been placed in the appliance. Make sure that
the lter (FY4440/30) is properly installed.
• The particle sensor is wet. The humidity level in your room is high
and causes condensation. Make sure that the particle sensor is
clean and dry (see the chapter “Cleaning and maintenance”).
• Room size is large or the outdoor air quality is poor.
For optimum purication performance, please close the doors
and windows when operating the air purier.
• There are indoor pollution resources. For instances, smoking,
cooking, incense, perfume or alchohol.
• Filter reaches the end of life. Replace the lter with a new one.
The color of the air
quality light always
stays the same.
• The particle sensor is dirty. Clean the particle sensor (see the
chapter “Cleaning and maintenance”).
The appliance
produces a strange
smell.
• The rst few times you use the appliance, it may produce a plastic
smell. This is normal. However, if the appliance produces a burnt
smell even if removing lter, contact your Philips dealer or an
authorized Philips service center. The lter may produce smell
after being used for a while because of the absorption of indoor
gases. It’s recommended that you reactivate the lter by putting it
in direct sunlight for repeated use. If odor still exists, replace the
lter.
The appliance is extra
loud.
• It's normal if the appliance runs at the Turbo mode.
• In the Auto mode, if the appliance is too loud, maybe the
appliance runs at high speed because air quality becomes worse,
or your personalized setting in App triggers a higher fan speed.
You can choose the Sleep mode, or change the settings in the
App.
• If there is abnormal sound, contact the Consumer Care Center in
your country.
• If anything drops into air outlet, it may also cause abnormal loud
sound. Immediate turn o appliance, turn appliance upside down,
to get foreign objectives out of appliance.
The screen displays
that the back cover is
opened.
• Shut o the power rst, then install the back cover correctly.
Connect the appliance with power and retry.
Error code “E1”
displays on the
screen.
• The motor has malfunctions. Contact the Consumer Care Center in
your country.

15EN
English
Problem Possible solution
The Wi-Fi setup is
not successful.
• If the router your purier is connected to is dual – band and
currently it is not connecting to a 2.4GHz network, please switch
to another band of the same router (2.4GHz) and try to pair your
purier again. 5GHz networks are not supported.
• Web authentication networks are not supported.
• Check if the purier is within range of the Wi-Fi router. You can try
to locate the air purier closer to the Wi-Fi router.
• Check if the network name is correct. The network name is case-
sensitive.
• Check if the Wi-Fi password is correct. The password is case-
sensitive.
• Retry the setup with the instructions in section “Reset the Wi-Fi
connection”.
• The Wi-Fi connectivity can be interrupted by electromagnetic or other
interferences. Keep the appliance away from other electronic devices
that may cause interferences.
• Check if the mobile device is in airplane mode. Make sure to have
the airplane mode deactivated when connecting to the Wi-Fi
network.
• Consult the help section in the App for extensive and up-to-date
troubleshooting tips.
