On this page you can find everything about why humidity is important and whether you need a humidifier in your home.

Ultrasonic humidifiers

Ultrasonic humidifiers contain a small metal plate that vibrates at an ultrasonic frequency. These ultrasonic sounds are inaudible to humans, but they are able to convert water particles from the humidifier's built-in reservoir into a cool mist. The device blows this fine mist into the air, increasing the humidity in the room.

Safe and cold mist, rapid increase in humidity, lime filter replacement optional*, quiet operation.

Spreading of mineral/lime dust*, scale and bacterial growth in the water tank*, regular maintenance, no humidity control.

*=Use of an anti-bacterial lime filter in an ultrasonic humidifier reduces lime deposits in the water tank and prevents lime deposits from the mist.


Cold Water Evaporators

A cold water evaporator uses a water-absorbable filter to draw water from the reservoir. A fan that then blows through the filter causes the air to absorb the moisture. The higher the relative humidity, the harder it is to evaporate water from the filter. Therefore, this type of humidifier is self-regulating - as the humidity increases, the humidifier's water vapor output naturally decreases.

Filter to remove bacteria and lime from water, self-regulating, low maintenance.

Filter replacement cost, less quiet operation due to fan
