How many DampRid containers should I use?
This depends upon how much dampness is present and this can vary by location. Since the presence of musty odors indicates a mildew/dampness problem exists, we suggest you add a DampRid container to the problems area every few days until the musty odors disappears. You will have then found the correct number of DampRid containers to use. Check the package for suggested size of room for each individual product.
