Shelf-life desiccant bag and alternatives

Discover the lifespan of a desiccant bag and the possible alternatives. AirSponge: reusable, guaranteed for 3 years, maintenance free.

Les desiccant bags contain silica beads (or silica gel) capable of absorbing moisture from the air into their pores.
Once saturated, these beads can no longer adsorb water, which limits their effectiveness.

Factors that influence lifespan

  1. Environmental humidity


    • In a very dry environment, the bags can remain effective for several months.

    • In a humid environment, they will need to be replaced more frequently.
  2. Packaging quality


    • If the packaging is not airtight, humid outdoor air penetrates and accelerates the saturation of the silica beads.

Regeneration of desiccant bags

When silica beads are saturated, it is possible to regenerate :

  • Heat in an oven at 120-130°C for at least one hour.
  • This method requires energy and can be restrictive.

Our product Air Sponge, on the other hand, regenerates at room temperature, offering a practical and economical solution.
