Highlights
Natural evaporation process
Hygienic and natural evaporative process to
ensure optimized performance. Dry air passes
through the humidifier. Water vapor is added
and more humid ai r exits the humidifier into
the surrounding air. NanoCloud technology
uses such a natural evaporation process which
draws dry air in, adds water molecules to the
air, and emits humidified air into the room.
No wet spots & white dust
With its 360° design, humidified air is evenly
distributed throughout the room, with no drips
on the floor or desktop. Our NanoCloud
technology also reduces the spread of
minerals i nto the air, which prevents white dust
from settling onto your furniture and flat
surfaces.
Spreads 99% less bacteria
Once the water is evaporated, the water
molecules are so small that the water mist
becomes i nvisible to human eyes. And
because they are so small, these molecules
are less able to carry bacteria i nto the air. Our
laboratory testing confirms that NanoCloud
technology spreads 99% less bacteria than
leading ultrasonic humidifiers.
No hot water
A humidifi er with low risk of burns from hot
water or warm steam. NanoCloud technology
does not heat the water, preventing risk of
burns from hot water or warm steam.
Quiet sleep mode
In sleep mode, the humidifier runs at minimum
noise level and all lights are off except for the
speed indicator. This setting ensures you can
maintain your desired humidity level even
when you are sleeping.
Easy-to-fill tank
Fill with a jar or bring the water tank to the tap.
The 'max' indicator clearly shows how far to fill
the tank. When the tank is empty, the
humidifier automatically shuts off and the
display indicates a re-fill is needed.
Easy-clean design
A round and minimalist design makes cleaning
easy. This humidifier does not have a heating
plate, so descaling is not required.
2 fan speed
The Philips Humi difier has 2 fan speeds and a
humidification rate of 250 ml/h on the highest
setting. It is perfect for medium si ze rooms in
the house, up to 38 m 2 .*
Best-in-class cleanability
Cleaning humidifiers inside and out –
especially the water tank – has never been
easier
