risks and damage to the appliance.
Troubleshooting and repairs
If the appliance requires repair, always contact the manufacturer’s Customer Services.
Always insist on original spare parts.
Repairs carried out by unauthorised personnel may be dangerous and invalidate the warranty.

Technical characteristics en
De’Longhi purifiers incorporate the latest technological
features for home air filtration;
The air is taken in through the front panel;
The contaminated air passes through a washable prefilter which removes large impurities such as coarse dust,
hair, etc. The partially filtered air is then passed through
a long-lasting HEPA filter with a large filtering surface,
easily recognisable by the special pleated paper. This
HEPA (High Efficiency Particulate Air) filter removes impurities down to a size of 0.3 microns, filtering all types
of particle including tobacco, house dust and pollen;
The air is then passed through a black active carbon
filter which removes a variety of pollutants and unpleasant odours such as smoke, fine dust particles and
formaldehyde. Some models have an active nano-silver
filter. The appliance is also equipped with a filter with
photocatalytic titanium dioxide with a UVC lamp.
The purified air is returned to the room through the top
grille. The upward flow of air improves air circulation
in the environment, without generating irritating currents.
When active, the independently controlled ionizer releases a cloud of beneficial negative ions into the room
together with the outflow of filtered air, allowing the
removal of dust particles, pollen, cigarette smoke and
car exhaust fumes.
On contact with the negative ions, the particles of dust
suspended in the air are negatively charged and can
combine with the positively charged particles to form
larger particles which will then be filtered by the purifier. The negative particles are attracted by positively
charged surfaces, such as the floor or wall.
Negative ions improve the ion balance in the atmosphere, as positive charges generally predominate. The ionizer therefore helps reduce the static electricity created
by the presence of rugs, carpet, televisions and computer screens.

Read these instructions before using the appliance.
• Unpack the air purifier and place on a stable flat surface
so that the air intake in the front panel and air outlet
(top grille) are not blocked. A good position in the room
might be at least 3 feet (1 m) from the wall.
• Remove the front panel (fig. 3). Inside the purifier you
will find the prefilter (B) and HEPA filter/active carbon filter (C) and the nano-silver filter (D) (Model AC230 only)
packed, depending on the model, in a plastic bag. And
the photocatalytic filter (E) fixed to the air intake grill.
• Remove the filter(s) (depending on the model) from the
bag, as shown in fig. 2, then place them in the following
order: nano filter, with the silver side adhering to the
appliance, HEPA filter with the black active carbon side
resting directly on and adhering to the nano-silver, then
the prefilter, slotting it in place as shown in fig. 4.
• Replace the front panel;
• After making sure the voltage in your home corresponds
to the voltage indicated on the appliance, plug the appliance into the mains socket.
Remove the protective film from the control panel.
Turn the appliance on by touching the ON/OFF icon (O).
The corresponding icon lights up and the appliance comes on automatically at minimum speed. The AUTO icon
(Q) flashes and the air quality LED indicators (G) light up
orange for 3 minutes.
This time is necessary for the appliance to detect air
quality, then the AUTO icon becomes steady and the air
quality LED indicators (G) change colour depending on
the air quality detected and also the fan speed changes
BAD AIR QUALITY:
orange + max. fan speed
SATISFACTORY AIR QUALITY:
green + med. fan speed
GOOD AIR QUALITY:
blue + min. fan speed
Please note: the change in colour of the air quality
indicator (G) is always sequential:
ORANGE <-----> GREEN <-----> BLUE
Please note: to vary the set fan speed, touch the icon
(P) corresponding to the required fan speed (Min/
• The LED corresponding to the selected speed lights up.
Please note: When the appliance starts after having
been turned off, using a light pressure on the ON/
OFF, it starts with the last function set with the exception of the auto-off function).
“AUTO” operation (Q)
Tap the “AUTO” icon, the appliance independently decides the fan
speed according to the air quality detected (min, med, max).
Ionizer icon (R)
For the release of negative ions into the environment through
purified air, touch the ionizer icon (R). The corresponding LED
This function can be used to turn the appliance off automatically after a given period of time.
With the appliance on, touch the auto-off icon (T) to select
how many hours should elapse before the appliance goes off
(1-2-4-8 hours), the corresponding LED comes on.
Care and Maintenance en
Do not clean the appliance by immersing in water.
Please note: Before performing cleaning and maintenance, always unplug the appliance from the
Tap the AQS icon (Air Quality System) to enable or disable
the air quality LED indicators (G). This function is particularly
useful if you want to completely eliminate the light source,
during night operation for example.
Note: the AQS icon enables or disables the LED indicators only while the air quality detection system is
MAINTENANCE AND FILTER
• Remember that the efficiency of your air purifier depends on the condition of the filters. They should therefore
be checked regularly by removing the front panel.
• Check the prefilter regularly.
If large quantities of dust and other impurities have accumulated, remove and hand wash in hot soapy water.
Dry thoroughly before replacing in the appliance.
• Frequent cleaning of the prefilter helps extend the life of
the HEPA filter/active carbon filter.
• When the filter goes from white to dark grey or brown,
it must be replaced.
HEPA filter exhausted LED (X)
When the filter LED (X) flashes, the HEPA filter/active carbon
filter must be replaced. Proceed as follows:
After unplugging the appliance from the mains socket, remove the front panel (A) and the prefilter (B), then remove the
HEPA filter/active carbon filter (C) and replace with a new one
obtainable from De’Longhi’s authorised Customer Services.
Replace the filters in the correct sequence as described above,
then put the front panel back.
At this point, turn the appliance back on and reset as follows:
• insert a fine object into the hole in the reset button (U) and
press until the flashing LED comes on steadily. Release the
button. After about 5 seconds, the filter LED (X) goes off.
HEPA filter/active carbon filter (C)
• The life of a HEPA filter/active carbon filter depends on
the operating conditions of the appliance.
In general, considering about 4 hours operation a day at
medium speed with normal quantities of dust/smoke in
the air, it should last about 6 months. However, when the
HEPA filter exhausted LED (X) flashes, it must be replaced.
(See the HEPA filter exhausted LED indicator paragraph).
To replace the HEPA filter/active carbon filter, first remove the prefilter (B), then remove the HEPA filter/active
carbon filter (C) and replace with a new one.
• Do not wash the HEPA filter/active carbon filter. When
exhausted, it cannot be regenerated.
• Replacement De’Longhi filters can be obtained from the
manufacturer’s Customer Services and and select retailers.
Please note: Before performing cleaning and maintenance, always unplug the appliance from the
Please note: Pressing the reset button (U) for less
than 3 seconds activates/deactivates the icon tone.
Please note: The appliance has a safety microswitch
(Y) which turns the appliance off whenever the
front panel (A) is removed.
Cable compartment (M)
The appliance has a practical cable compartment (M), useful
for storing the cable when the appliance is not in use.
Nano-silver filter (D) (Model AC230 only)
• The nano-silver filter (D) has a lifelong duration because
it is protected by the HEPA filter. However, regular vacuuming is recommended.
CLEANING THE APPLIANCE
Photocatalytic filter with UVC lamp (E)
• It is a permanent filter that requires no maintenance. IT
MUST NEVER BE REMOVED as it acts as protection for
the UVC lamp.
Clean the outside of the appliance with a soft slightly damp
cloth to remove dust, dirt or fingerprints. The front panel and
prefilter can be removed and washed separately in hot soapy
water (they are NOT dishwasher safe). Dry the components
thoroughly before putting them back in the appliance. The
top grille can be cleaned with a soft brush.
