The importance of a workplace humidification system

Indoor dry air problems in the workplace can have a serious effect on the comfort, health and productivity of employees. Here we explore why a workplace humidification system offers an efficient solution to low indoor humidity.

What is a healthy level of humidity?

Leading industry bodies such as CIBSE (Chartered Institution of Building Services Engineers), BRE (Building Research Establishment) and BSRIA (Building Services Research and Information Association) agree that the ideal indoor humidity level for a comfortable working environment is between 40% and 60%. Unfortunately, many UK offices fall well outside this range. A survey conducted by Volvic mineral water found that one in five UK workplaces are as dry as the Sahara desert, and that most employees associated low humidity with a stressful environment.

What are the consequences of low workplace humidity?

The effects of low humidity on employees include headaches, sore throats, itchy skin and eye irritation. Contact lens wearers are especially prone, because below 30% relative humidity (RH), dust and dirt particles settle on lenses which causes greater irritation. Persistent dryness in the nose and throat increases susceptibility to colds and coughs, one of the reasons low humidity is seen as a factor in sickness and absenteeism. In addition, staff may be susceptible to electrostatic shock when RH drops below 40%.

How is humidity regulated?

Most offices should have some form of humidification system installed to maintain a comfortable RH of at least 40%. A humidifier can be implemented as part of a new or existing HVAC system, but it’s important that this is done by an experienced provider. That’s because there are many considerations to be made including Legionnaires’ disease regulations, water supply, humidifier location, control compatibility and maintenance requirements.
