Low air humidity affects both comfort and well being/health of people.

During the wintertime, when the relative air humidity indoor drops, eyes, skin, nose, mouth and respiratory problems increase. Low humidity levels permit easier transportation of bacteria & viruses through the atmosphere. High humidity levels increase the risk of proliferation of viruses and bacteria.

To prevent propagation and proliferation of biological contaminants, the humidity should ideally be kept between 40% to 60%rh.

Accurate humidity control will reduce problems of a dry atmosphere, helping to maintain comfort, protect equipment, providing a safer place to staff and visitors at the same time as promote patient health.

Steam is the rational choice for critical areas such as operating theatres; however Humifog is one of the few adiabatic systems certified for use in Hospitals.

Traditional choices for large hospital projects include gaSteam and ultimateSteam.
