Evaporative Humidifiers - Add Moisture To Your Environment

For comfortable living, moisture is essential. A humidifier is a device that adds comfort to your home by increasing humidity by adding moisture to the air. Evaporative humidifiers are one of the main type of humidifiers.

According to technology, humidifiers are classified as:

• Steam humidifiers. Also known as vaporizers, they release steam by boiling water.
• Warm mist humidifiers.  Similar to vaporizers but allow the steam to cool down and release as warm mist.
• Evaporative or cool mist humidifiers.  These have a fan that blows moisture into the room as cool mist.
• Ultrasonic humidifiers.  These have a mechanism to break water into humid vapors, through vibration, and release the vapors into the air.
• Impeller humidifiers.  These have a rotating disc that throws the water onto a diffuser that breaks it into fine droplets, which float into the air.

Evaporative Humidifiers – An Overview

These are the most common of all the humidifiers. They consist of a reservoir, a wick and a fan.

A reservoir is a tank, common to all humidifiers, containing water, which is filled before humidification. Depending on the model, the reservoirs are of different shape and size.

The wick is a filter that absorbs the water from the reservoir. Water from the filter is evaporated by the blowing of the fan on it. Water evaporation is dependant on the relative humidity of the room. Lower the humidity, higher the evaporation and vice-versa. Depending on usage, filters are changed every three months.

Evaporative humidifiers come with a humidistat that controls and regulates humidity in the room. The fine atomized mist does not overly soak everything and does not leave traces of mist on the windows. The humidifier's automatic humidistat prevents the room from being over humidified. Over humidification can lead to growth of mold.
