Winter brings cold and dryness and while
air dryness can be relief to some, excess
dryness can lead to health problems (dry
nose, throat, lips, skin itchiness). Lower
humidity can also lead to cracks in paint
and furniture and can damage musical instruments
(pianos, etc.) made of wood. As a rule of
thumb, 30-50% relative humidity is desirable.
There are four common types of
- Ultrasonic humidifiers create a cool mist
by means of ultrasonic sound vibrations
- Impeller humidifiers use a high-speed rotating
- Evaporative humidifiers use a fan to blow
air through a moistened absorbent material,
such as a belt, wick, or filter.
- Steam (mist) vaporizers heating water with
an electrical heating element or electrodes
to create steam. It can be dangerous to operate
a hot steam humidifier near children. A warm
mist humidifier will cool the air before
releasing it in to the room.
- Choose a unit that is easy to clean since
minerals and other foreign elements in the
water will accumulate inside the unit.
Finally, steam and evaporative
are not expected to release substantial
