Replacement of the demineralization
cartridge
Always unplug the unit before removing the
water tank. Do not touch the water in the base
during operation!
The water tank is equipped with a demineralization cartridge.
This cartridge has to be replaced every 2 – 3 months. If
the water is very hard, it may be necessary to replace the
cartridge earlier. White dust around the device is a sure sign
that the cartridge needs replacing. Please note white dust
is not harmful. If white residue still forms around the device
after a new cartridge has been inserted, please make sure
that the water you are using is untreated. If the water flows
through a decalcification system – such as an ion exchanger
– (sodium is added to remove calcium) in the building before
it is used in the humidifier, salt can precipitate as white dust
around the device. The demineralization cartridge and or the
granules must be exchanged at the latest after 6 months or
the unit does not reach its full performance anymore.
Option A: replace the resin
• Remove the water tank from the base and unscrew the
water tank cap (29). Caution: the mist outlet is loose!
• The demineralization cartridge is attached to the tank
cap. Unscrew the cartridge from the cap by turning it
counter­clockwise (30). Important: do NOT dispose of
the water tank cap!
• Open the cartridge (31).
• Throw the content into the waste (Attention! Disposed
resin can make the floor slippery!) (32).
• Place the enclosed pink styrofoam piece in the center
of the cartridge. Do not push it to the bottom as it will
be difficult to remove afterwards (33).
• Pour the contents of one refill resin bag into the plastic
cup that is included with the refill resin packaging (34).
• Place the empty cartridge with the plug in the center
onto the plastic cup (35).
• Turn the plastic cup and cartridge over and shake until
all resin is in the cartridge (36).

• Remove the plastic cup and the pink styrofoam piece
from the cartridge (37) and retain for future use (the
refill resin consists of 3 refill bags) (38).
• Close the cartridge (39).
• Soak the demineralization cartridge in a water bath
24 hours before using it (42). The resin has to absorb
water to reach maximum performance. If it is soaked in
the tank, make sure to exchange the water and empty
the water from the base before using the humidifier.
• Screw the cartridge on the water tank cap (43).
• Screw the cartridge on the bottom side of the water
tank, put the tank on the main body (44).
Placing granules in the center of the cartridge
allows them to escape in the unit or to clog the
unit. The unit will no longer operate properly and
the granules need to be cleaned out thoroughly.
Option B: replace the whole cartridge
• Remove the water tank from the base and unscrew the
water tank cap (29). Caution: the mist outlet is loose!
• The demineralization cartridge is attached to the tank
cap. Unscrew the cartridge from the cap by turning it
counter­clockwise (30). Important: do NOT dispose of
the water tank cap!
• Throw the whole cartridge into the waste (40).
• Unpack the new cartridge (41).
• Soak the demineralization cartridge in a water bath
24 hours before using it (42). The resin has to absorb
water to reach maximum performance. If it is soaked in
the tank, make sure to exchange the water and empty
the water from the base before using the humidifier.
• Screw the cartridge on the water tank cap (43). Close
tank cap well and place the tank on the main body
(44).
