Silica gel desiccant is a moisture-proof and dehumidifying product that can directly contact with food and drugs. It is also the only environmentally friendly desiccant approved by the European Union. For general silica gel desiccant, we set the effective use time of the product. If the sealed silica gel desiccant is not opened, it will be effective within one year.

The specific usage time depends on the environment. The time for a desiccant under high humidity conditions to absorb moisture is different than that of a desiccant under low humidity conditions. When it reaches its moisture absorption capacity, it stops absorbing moisture.
