Humidifiers – A First Time Buyers Guide
Lucy Bartlett
The quality of outdoor air is a major concern for us all.
Social groups do all they can to protect the environment and
air. However, at the same time, people do not think about the
polluted air they breathe and about the poor quality of air in
offices and our homes. In most of the cases, the quality of
indoor air is inferior to air outside.
Those living in a very dry climate find a humidifier a very
convenient household appliance to increase the moisture in the
room. Humidifiers can be used to humidify the whole house or a
single room. Furnace humidifiers can be used to humidify the
entire house when connected to HVAC system.
A fan, wick and reservoir constitute the basic parts of wick or
evaporative humidifiers.
The reservoirs in the humidifiers come in different sizes and
shapes. The output of moisture from the humidifier is made
possible by the water stored in the containing tank of the
humidifiers.
Water stored in the reservoir is absorbed by the wick which
acts as a filter. Water gets evaporated through the wick
depending upon the relative humidity. Higher evaporation will
take place in a room with low humidity while in a room with
high humidity, the evaporation will be low. This type of
humidifier is self regulating. The evaporated water is
circulated through the entire room with the help of the fan.
The wick in the humidifier needs regular cleaning and
replacement. When it is not done it stops humidifying the area
and the water level will remain constant. Humidifiers come in
different varieties such as steam humidifiers or vaporizers,
impelling humidifiers and ultrasonic humidifiers.
Steam humidifiers boil water and release the moisture and steam
into the air. Medicated inhalant can be added to the stored
water which will help reduce coughs. The boiling process
creates lot of noise. These types of humidifiers are the least
expensive.
Impeller humidifiers use a rotating disc which throws the water
at the diffuser and the water is broken into very fine droplets
and then float in the air.
Ultrasonic humidifiers use a metal diaphragm vibrating at an
ultrasonic frequency to produce water droplets which exit the
humidifier in the form of a cool fog. This process causes the
humidity to come down. This humidifier operates very silently.
If not cleaned regularly it might cause contamination by
bacteria in the water and in the surrounding atmosphere.
Distilled water should be used in ultrasonic and impeller
humidifiers. Otherwise the minerals in the water precipitate as
a fine dust which will cause health disorders. In wick
humidifiers the wick traps the mineral deposits.
