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. 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.

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. Immedia-

tely 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 as much as possible. The contents of the

cartridge need to be soaked 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 everywhere. Immedia-

tely 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.

For refilling the DMC, wad a piece of paper or paper

towel and place in the middle of the DMC. For placing

granules in the cartridge, a suggestion is to use a

spoon so that no granules get in the middle of the

cartridge.

Caution: Do not dispose of granules in sink! Used

granules must go in waste!
