General Humidifier Questions
en
Q. Why isn't there enough moisture in my room?
A. How often do you run the unit? If the unit is only run at
night, then during the day the moisture level will drop if
moisture is not constantly added to the air.
Q. Do you leave your door open or closed when the
unit is running?
A. a) By leaving the door open, this allows moisture to
leave the room and go into other areas of the house.
If you would like the moisture to stay within one
specific room you should consider closing the door
while the unit is running.
A. b) Wood, leather, carpet, curtains, and other types of
fabric soak up a lot of moisture, thus not leaving en-
ough moisture for the air. If the window is left open,
then this allows moisture to escape the room. Ano-
ther factor is a lot of times the unit is placed next to
a heating device. The idea is that the air blowing
into the room will quickly place moisture around the
room. Unfortunately, this concept does not work
because the hot air coming out of a vent will soak
up most of the moisture, and none of the air within
the room will receive any.
Q. How much moisture do I need in my room?
A. Suggested humidity levels are between 40 – 60%.
Q. What are the effects of too little or too much
humidity?
A. Dry air can cause dry skin, static electricity, out of tune
musical instruments, increased levels of dust (dry air
causes dust to rise), damage to wooden objects
(dry out and eventually cracks appear), discomfort,
sickness, and dries out nasal membranes.
Over-humidifying the air can cause mold and wallpaper
to peel.

Q. Why do I need a humidifier when I can just open
my window?
A. The moisture level within the outside air is not high
enough to humidify a room. The colder the air the less
moisture it is capable to hold, and the more the air is
heated up the percentage of relative humidity is lower.
Relative humidity means the amount of water vapor in
the air, compared to the amount the air could hold if it
was totally saturated. The difference is higher between
outside and inside temperatures; more humidification
is needed because of the dry air in the room.
Q. Where should I place my humidifier?
A. The unit should be free-standing and not close to a
wall, window, door, or thermal bridge so that air may
circulate around the unit.
Steam Humidifier Questions
Q. There is no fill-line on the water tank, how far
may I fill it up?
A. There is no fill line on the water tank, and it may be
filled all the way to the top.
Q. H umidity level is not changing or does not reach
the desired humidity level.
A. If the water tank needs refilling more than once per
day, the unit is working properly and the climatic
condition in the room has an influence on the humidity.
Reasons for low humidity level:
• air circulation is very high (air is fully exchanged
several times per day – the humidifier needs to start its
work from scratch)
• insulation of home (see air circulation)
• open space with high ceilings (not only the footage of
the room counts but also the height) – high-rise buil-
dings require more humidification.
• open windows – works similar to air circulation (if it is
very cold outside don't open the window more than
2 times per day for 3 minutes)
• big difference between outside temperature and inside
temperature – the colder the air the less moisture it
is capable to hold and the more the air is heated up
the lower is the percentage of relative humidity (=the
amount of water vapor in the air, compared to the
amount the air could hold if it was totally saturated)
• position of the unit - if it is placed close to a door,
window or air vent. This increases the air circulation.
Q. No mist / unit is not working
• If the unit is not working and the empty light is not
flashing you might have set the desired humidity too
low and the current humidity level in the room is
higher. That is why the unit switches off automatically.
Q. Water tank cap is too tight to unscrew
A. This could be a cause of the air pressure within the
water tank. Press the spring on the bottom of the water
tank cap to release air from the water tank.
Continue to do this until you are able to unscrew the
water tank cap.
