Up to 6 months of protection
Sump‐Dri units are expected to protect a 75-100 cu.ft. space for up to 6 months under typical conditions, but functional duration may be shorter or longer depending on humidity level, temperature, how well the sump is sealed, and frequency that the sump space is opened. Larger spaces or extended maintenance periods may elect to install multiple units. Sump-Dri units should be changed when the desiccant in the upper chamber has completely depleted.
