What does humidification mean?
Humidification is the controlled addition of moisture to air or another environment. It is used in homes, museums, hospitals, greenhouses, and industrial facilities where excessive dryness could cause discomfort, damage materials, or interfere with a process. In buildings, humidification systems release water vapour to maintain a comfortable indoor environment and may help reduce problems associated with dry skin, irritated respiratory passages, and the cracking or warping of wood. The word also has a specialized role in conservation, where carefully regulated moisture levels protect paintings, books, and wooden objects. Although humidification can make an environment feel more comfortable, excessive moisture may promote condensation, mould, and dust mites, so it is normally managed according to established safety and environmental guidelines.
nounThe process of increasing the moisture content of air or another environment, especially to improve comfort, preserve materials, or support health and industrial processes.
