 Humidifiers are frequently used in homes to reduce the physical discomforts of arid nose, throat, lips and skin. The dampness they give to dry air also aids to lessen usual inconveniences caused by winter heating like static electricity, stripping wallpaper and gaps in paint and furniture. On the other hand, excess humidity may arouse the appearance of biological organisms in the house. They embrace dust mites, which are minute animals that create materials arousing allergic reactions to the home dust and mustiness.
Types of Humidifiers and Associated Pollutants
Console humidifiers are placed in cabinets that are created for floor use. Portable humidifiers are not so big and more conveniently moved. Central humidifiers are fixed to heating and air-conditioning systems and moisten the entire house. The two kinds of humidifiers generating the greatest distributions of biological organisms and minerals are:
- Ultrasonic that produces a chill mist with the help of ultrasonic sound vibrations.
- Impeller or “cool mist” humidifier that generates a cool with the help of a high speed rotating disk.
Two other kinds of humidifiers may allow for appearance of biological organisms in case they have a tank, which keeps the water, though usually distribute fewer contaminants in the air. They are:
- Evaporative that spread the humidity into the air unnoticeably by means of a ventilator blowing air through the damped absorbent material like a filter, wick or a belt.
- Steam vaporizer that generates steam by warming water with an electrical heating element or electrodes. “Warm mist” humidifiers are a kind of steam vaporizer humidifier where the steam gets chilled prior to leaving the machine.
Recommendations for Use and Care
It is essentially to use a humidifier only under specific conditions, to use the right humidity setting for current conditions and to clear it carefully.
The probable health influences resulting from the spreading of microorganisms and minerals by domestic humidifiers are not completely realized. In the meantime, it may be reasonable to decrease the possibility for personal exposures to these substances by taking the following preventive measures, especially when using impeller and ultrasonic humidifiers.
