Humidity Controller (Art)

Humidity Controller (Art)

Protect Art Pieces and Artifacts with Humidity Controllers Art Sorb. Historic art pieces and artefacts are highly vulnerable to damage due to moisture and temperature fluctuations. The presence of humidity in the environment can damage these valuable historical assets. It can cause cracking, colour fading, and deformation. Therefore, they require a robust and powerful solution to counter the effects of humidity and temperature changes.

Humidity Controller (Art) protects invaluable art pieces and historical artefacts. They prevent humidity from destroying treasured historical documents, paintings, fragile fabrics, and many other timeless pieces. These products have accurate moisture absorbing capabilities, which help in maintaining ideal moisture and temperature levels.

The Humidity Controller (Art) is made from highly sensitive silica, which absorbs excess moisture and maintains stable humidity levels within the sealed environment. Through this maintenance-free and cost-effective humidity controller, it is possible to prevent the degradation of art pieces due to climatic fluctuations and preserve heritage items for generations. It remains effective for up to five years.

Quality Art Sorb Humidity Controller at Om Mas 

High-quality humidity absorbing solutions help preserve the historical pieces of art, documents, delicate fabrics and many more things from damage and deterioration. They have five-time moisture buffering capabilities as compared to conventional silica gel products. These products work more efficiently at higher relative humidity levels. Our Art Sorb products are available in the form of non-woven sheets, cassettes, and beads. Place the Humidity Controllers at the bottom, sides, and top of the display cases or within a frame inside a box.


The Humidity Controller ArtSorb can be used in display cases and is optimal when it is airtight. When a heat source such as a light is present, use a heat shield to block the light or place the light outside the box. For the Humidity Controller ArtSorb to function effectively, it must have adequate contact with air, is airtight, and is spread out evenly. It must also not be in touch with the artefact. The lifespan of the Humidity Controller ArtSorb typically lasts for about 5 years but depending on the environment. However, during these 5 years, a humidification process is needed, which takes place two to three years after first use. A hygrometer can be used to check for dehumidification.


Ordinary Silica Gel desiccants are only capable of absorbing moisture, which results in an overly dry environment that is not optimal for artworks. However, the Humidity Controller ArtSorb can react to the humidity changes, providing precise humidity control environments between 40-70% relative humidity.

  • Works well with artifacts and arts
  • Lasts for a lengthy period of 5 years and needs to be re humidified after 3 years
  • Maintains relative humidity between 40%-70%
