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.
Air quality light color Air quality level
Blue Good
Blue-purple Fair
Purple-red Poor
Red Very poor

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

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.

14 EN
Problem Possible solution
The appliance
does not work
even though it is
plugged in.
• Check if the back cover is properly installed.
• 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").
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.

15EN
English
Problem Possible solution
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.
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 ‘Set up
the Wi-Fi connection when the network has changed’.
• 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.
