First ever World Humidity Control Day to take place in March

The Humidity Control Group, a specialist group within the HEVAC trade association and part of FETA, has announced that the inaugural ‘World Humidity Control Day’ will take place on 12th March 2024.

World Humidity Control Day commemorates the visionary John Frederick Daniell. Born on March 12, 1790, Daniell was an English chemist and physicist who, in 1820, invented a dew-point hygrometer - a device that indicates atmospheric humidity - which then came into widespread use.

Humidity control is important for several reasons. High humidity levels can lead to discomfort, making the air feel heavy and causing excessive sweating, whilst low humidity levels can cause dryness in the air, which can lead to respiratory issues, dry skin, and irritation of the eyes and throat. Humidity control is therefore used to maintain a comfortable and healthy indoor environment.

In establishing a World Humidity Control Day, the Humidity Control Group aims to raise awareness of this important subject and the impact it has on our daily lives and the buildings we live and work in.

As well as developing a World Humidity Control Day logo, the Humidity Control Group has created a website dedicated to the newly formed official day. The website features detailed information on why humidity control is so important and can be found at

John Barker, Chairman of the Humidity Control Group, commented: “World Humidity Control Day gives us the perfect platform to raise the profile of humidity control whilst recognising the achievements of John Frederick Daniell. By improving education and awareness we can better promote the many benefits of maintaining optimum humidity levels in the buildings we live and work in.”
