Description of the unit
The Air Washer W490
• washes and humidifies the air without filter mats
• includes an innovative water quality maintenance
system (ISS)
• runs with little noise at two operation modes
• is suitable for room sizes up to 50 m2
• is manufactured with high-quality components with
a long lifespan
In the inside of the Air Washer, special humidifier discs
rotate through a water bath and in doing so clean the
air streaming by of impurities in a natural way – as the
air is washed clean by the rain in nature. Air humidification occurs following the self-regulating principle of cold
evaporation. Therefore the Air Washer creates optimum air
moisture, without additional control units being necessary.
Humidifier discs
The honeycomb structure of the humidifier discs allows
proven release of large amounts of water into the air. The
unit cleans the air with nature as its model. In addition, the
unit also guarantees filtering of pollutants as well as pollen
and animal hair from the air.
Ionic Silver Stick (ISS) (34)
The Ionic Silver Stick utilizes the antimicrobial property of
silver and provides one season of optimum water quality
maintenance in all AIR-O-SWISS and BONECO humidifiers.
The ISS begins working as soon as it comes into contact
with water – even if the unit is switched off. The ISS is
intended exclusively for use in humidifiers.
Safety instructions
• Prior to putting the Air Washer into operation, read
the instructions for use thoroughly and retain them
well for later consultation.
• Only use the Air Washer in living areas and within
the technical data specified. Unintended use can be
a danger to health or life.
• Children cannot recognize the danger in handling electric appliances. Therefore always supervise children
who are near the Air Washer (5).
• Those unfamiliar with the instructions for use as well
as children and people under the influence of medicine,
alcohol or drugs may not operate the unit, or only operate it under supervision.
• If the unit is knocked over so that water leaks, the
power plug must be unplugged immediately. The unit
must then be dry for at least 3 hours before the power
plug may be plugged in again.
• Do not add any additives such as essential oils directly
into the water tank or the water base. These additives
will damage your appliance! Appliances that are damaged by additives are excluded from the warranty.

Connect the Air Washer to the mains (signal tone) and press
button A (12). The digital display comes on and shows the
current humidity. The Air Washer is in Normal mode.

Symbol «H» High) in normal mode
To switch off, press button A.
Operating W490
A) Switching on/off
Pressing button A switches the appliance on. Pressing it
again switches the appliance off. Button A is also used
to start the Cleaning mode. See section «Cleaning mode»
(20 – 28).
B) Setting humidity level
The appliance is fitted with a hygrostat. This measures the
relative air humidity and automatically switches the appliance off when the desired value is reached. When switching
the unit on, the desired value is preset to 55%.
The desired value can be adjusted in steps of 5% by pressing button B. While selecting the humidity output, the
desired value is blinking. The word DESIRED appears on
the display (F). The setting for the relative humidity ranges
from a minimum of 30% to a maximum of 70% relative
humidity or «CO» continous mode. A relative humidity
of between 40 and 60% is recommended. After a few
seconds, the display automatically changes to show the
current value (CURRENT) (F). Upon reaching the desired
relative humidity, the unit automatically switches off
(display shows DESIRED and CURRENT) (F). If the desired
relative humidity falls, the appliance automatically switches
on again.
Quick display of current relative humidity
When the unit is switched off (mains cable is connected),
the current relative humidity can be shown in the display
by briefly pressing one of the B buttons. This display automatically goes out after a few seconds.
C) Changing the output level
The Air Washer can be operated on two output levels.
Press button C to select between output levels Low «L»
(night-time mode) and High «H» (Normal mode). The chosen
output level is shown in the display by symbol G.
D) Change Ionic Silver Stick (ISS)
The letter D in the display indicates that the Ionic Silver
Stick (ISS) must be changed. The symbol remains visible
until both B buttons are pressed simultaneously and held
down for approx. 5 seconds.
E) Cleaning the appliance
The letter E in the display indicates that the appliance must
be cleaned. The symbol appears as long as the cleaning
mode is activated or both B buttons are pressed simultaneously and held down for approx. 5 seconds.
F) Current/Desired Display
If DESIRED appears on the display, the value in % next to it
signifies the desired relative humidity, i.e. the desired value
is shown. If the display shows CURRENT, then the current
relative humidity is shown.
H)Automatic switch-off
«Tank empty»
The water quantity is easy to see thanks to the transparent
water tank. The display on the appliance also shows when
the unit should be refilled with water. If the water level falls
below the minimum quantity, the appliance automatically
switches off. A red blinking symbol (H) appears on the
display. When water is added, symbol H goes out and the
appliance continues operating.
Warning: When lifting the upper part off the base, the appliance also switches off. In this case, the red blinking F
symbol will also appear on the display. Only when the upper
part is replaced on the base does symbol H go out and the
appliance continues operating.
Cleaning the Air Washer (18 – 19)
• Regular cleaning is essential for hygienic, fault-free
operation, despite the Cleaning mode.
• Recommended cleaning intervals depend on air
and water quality as well as operating time.
• The Air Washer can easily be taken apart for
cleaning without tools.
The Air Washer must be emptied completely and
cleaned if the unit filled with water has not been
in operation for longer than a week.
Remove the ISS from the bottom base before
cleaning (20).
Only use CalcOff for decalcification and cleaning
of the product. Damage that is caused by the
use of other cleaning agents is not covered by
the warranty.
Cleaning mode (20 – 28)
Cleaning mode enables simple cleaning and decalcification
of the humidifier discs and the water tank.
Humidification does not take place when the appliance is in
Cleaning mode. The fan remains deactivated and only the
humidifier discs rotate.
Before switching the appliance to Cleaning mode, the water
base must be filled with hot water and the decalcification
agent CalcOff (21). Pressing and holding button A for 5
seconds switches the appliance to Cleaning mode (22).
Cleaning mode is shown in the display by flashing symbol
E (23). The value «1h» flashes in the display. Button B can be
used to change the cleaning period from 1 to 9 hours, depending on the level of soiling (23). After 3 seconds without
further input, the set value is taken as the «desired value»
and flashing display F changes back to «CURRENT». The
cleaning period is now permanently displayed and switches to minutes when the time remaining falls below the
1 hour mark. The cleaning period can be changed at any
time by pressing button B. At the end of the cleaning period,
the display shows the value «0h» and cleaning symbol E
flashes faster (24). Pressing button A ends the Cleaning
mode and switches off the appliance (24). The water base
must now be emptied of the CalcOff and rinsed (25–27)
(see section «Cleaning the water tank and bottom base»).
The next time the appliance is switched on, it will operate
in normal mode.
Do not clean the soiled disc package in the dishwasher!
Cleaning the water tank and water base –
every 2 weeks (29 – 34)
• Remove deposits from the water base with a plastic
or wooden brush and a diluted commercial dish detergent.
• Put the Air Washer back together after cleaning in the
opposite order.
