General Humidifier Questions
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
enough moisture for the air. If the window is left
open, then this allows moisture to escape the room.
Another 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, sick-
ness, 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.
Ultrasonic Frequent Questions
Q. Why does it say open/close on the demineralization
cartridge cap?
A. Those directions are there in case you decide to use
the refill option to replace the granules; the purpose is
for how to open and close the cap. If you did open the
cap before placing it in the water tank, you will most
likely notice that there are granules in the water tank
and the base of the unit. Immediately turn off the unit,
and empty the water out of the base and the water
tank. Begin removing all granules from base and water
tank. Use brush to clean around membrane.
Caution: Do not dispose of granules in sink! Used
granules must go in waste!
Q. I just replaced my cartridge, and the contents and
water in the base has turned a blue-green color.
A. This sometimes occurs when the cartridge, or even
the granules, are replaced. This does not occur with all
replacement cartridges or granules, and is a reaction of
water content and the Ultrasonic vibrations. This is not
an indicator to replace the cartridge.
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. What is the purpose of the demineralization cart-
ridge (DMC)?
A. The DMC removes minerals from the water to prevent
white dust. The contents of the cartridge need to be so-
aked for 24 hrs prior to first using the unit so that they
may fully expand and remove minerals from the water.
The contents of the DMC have a life of 2 – 3 months.
The cartridge may need to be replaced more often
depending on water hardness and how often the unit
is used. An indication of when the DMC needs to be
changed can be white dust or reduced amount of mist
output.
Q. Is it ok to use distilled water with the unit?
A. For best results with your ultrasonic humidifier use
distilled or reverse-osmosis water and remove the
demineralization cartridge.
Q. I just replaced the contents of the cartridge and
now have granules everywhere.
A. First, make sure there are no granules in the middle
of the cartridge. Placing granules in the middle of the
DMC allows them to escape in the unit. Immediately
turn off the unit, and empty the water out of the base
and the water tank. Begin removing all granules
from base and water tank. Use brush to clean around
membrane.
Caution: Do not dispose of granules in sink! Used
granules must go in waste!
Q. The directions tell me not to place the unit directly
on the floor, why do I have to elevate the unit?
A. The idea with this unit is to allow one to force humidity
into the air. Because of this, the carpeting or wood floor
surrounding the unit may become damp. If the unit is
