Dehumidifiers for Vaults and Archives: Secure Preservation Solutions from DeAir

Have you ever excitedly opened your "secret fund" hidden away in a closet after a humid season, only to find that the seemingly "immortal" polymer banknotes are stuck together, while the paper ones are spotted with green and white mold? Or when you look for an old savings book, a birth certificate, or memorable letters, you are shocked to see the ink has smudged and the paper has yellowed as if it's about to disintegrate? This is a common story, and a costly warning about the destructive power of the "hidden enemy" called Humidity.

For individuals, businesses, and government organizations that store assets of not only material but also informational and historical value, humidity control is no longer an option—it's a requirement.

The Gold Standard for Archival Humidity from International Organizations

To prevent degradation, the world's leading archival institutions have established very strict standards. This provides a scientific basis for us to create an ideal preservation environment.

• The U.S. National Archives and Records Administration (NARA): Recommends maintaining a stable relative humidity (RH) between 35% and 50%. They emphasize that maintaining stability is more important than achieving a specific number, as sudden humidity fluctuations are extremely harmful. (Source: NARA Storage Standards)
• The British Library: Suggests an ideal humidity range of 45% to 60% to strike a balance between preventing mold growth (which typically starts above 65% RH) and avoiding paper becoming too dry and brittle (which can occur below 40% RH).

The Detrimental Effects of Improper Humidity on Banknotes and Archived Documents

When relative humidity exceeds 60%, a series of decomposition processes are triggered, causing irreversible damage. This is one of the most essential benefits of using a dehumidifier—preventing these risks.

• For Banknotes & Valuable Prints: Paper and ink are ideal environments for mold to thrive. High humidity causes paper fibers to swell and weaken, leading to disintegration, tearing, and banknotes or pages sticking together, making them difficult to count and potentially destroying them completely.
• For Records, Books, & Documents: Ink on paper will smudge and fade, causing a permanent loss of information. Paper turns yellow, becoming brittle and prone to crumbling upon touch. This environment is also favorable for insects like termites and booklice to grow and cause damage.
