Humidification in Museums

Humidification in museums is needed to protect and preserve assets.  Controlling the environment around exhibits is critical to prevent damage caused by fluctuations in temperature and relative humidity (RH) levels.  There are a few different types of humidifier that will deliver the right humidity levels consistently all year round. 

When it comes to preservation, most materials have a “comfort zone” of between 45-55% RH (±3%).   Without humidification, be hard to control relative humidity levels as RH levels will fluctuate based on the time of year and even throughout the day and depending on the outside ambient conditions. 

Low relative humidity in museums, libraries, galleries and heritage environments can affect a variety of artefacts, resulting in materials warping, splitting, or cracking.  Over time these effects will worsen if not controlled properly, risking further damage and significantly reducing the item’s life. 

Artefacts affected by low humidity include:

  • Paper and papyrus

  • Wood

  • Ivory

  • Textiles

  • Potter, terracotta, stone, clay

We not only spread the risk of failure by installing multiple units, but our monitoring showed that the humidity levels became a lot more stable."
