Cool Air Humidifier

Also known as a cool mist humidifier, a cool air humidifier works by pumping out a cool mist to humidify your rooms. This mist is created by using a wick or filter which absorbs water from a reservoir. A fan then blows the moisture out into the atmosphere. This type is also known as an evaporative humidifier.

One drawback is that the fan does make a noise. However, some users don't mind the sound of the fan as it creates a steady 'white noise' effect which can be very relaxing, especially in bedrooms.

Users with children also prefer these types are there's no chance of a child suffering burns.

One great thing about these types of humidifier is that they're self-regulating. As the level of moisture in the air rises, the evaporation rate from the wick slows.

Cool air humidifiers are available in a full range of types including whole house, multi room and single room.

One popular type of cool humidifier is the ultrasonic. As the name suggests they use sound waves to create the vapor. A metal diaphragm vibrating at high frequencies creates water droplets.

Some benefits to this type of humidifier are:

• They're easier to clean.
• They can cover a greater area than warm air models.
• They are safer as they don't boil water.
• They use less electricity as there's no heating involved.

Some drawbacks to this type of humidifier are:

• They make more noise than warm air models because of the fan and water gurgling out of the tank.
• Some people report a clammy feeling at low temperatures.
• They require regular filter replacement.

If you live in a warm environment and have children, cool air humidifiers could well be the type for you.
