Often, museums and galleries house invaluable assets that, due to their age or nature, require a regulated or constant indoor climate. In order to counteract irreparable damage to exhibits, air humidification is indispensable.

Most of the exhibits in museums and galleries are proportionally made of wood, canvas, paint, fabric or paper. All these materials have hygroscopic properties and thus react even to the smallest changes in the humidity. A decrease in the humidity quickly leads to dehydration of the materials. Wood, for example, becomes cracked and brittle; color loses its adhesiveness and flakes off.

A constant humidity above 50% RH reduces electrostatic charging of exhibits and surfaces. They attract less “dust” and other particles when “uncharged”. For sensitive exhibits this leads to the extension of cleaning intervals.


Visitors and employees should feel comfortable in rooms. The relative humidity plays a big role. If the air is too dry, people release moisture from their water balance into the environment. The result is a dehydration of the skin, lips and eyes, which has a quick and immediate effect on human well-being . The function of the mucous membranes in the airways decreases and the body is less protected against bacteria and viruses.


The advantages of air humidification in museums and galleries at a glance:

  • Protection of valuable and irreplaceable exhibits
  • Create a healthy and inspiring feel-good atmosphere
  • Less cleaning effort due to lower dust load
  • Protection against electrostatic charge
  • High energy efficiency in the air conditioning of the premises
