If you go to their site cheaphumidors.com they sell replacements for the exact ones that come with
the humidor, even the rectangular beads humidifier they sell comes with the stainless steel mesh. I asked about why the metal in the foam one they said to keep the foam from falling apart. After alcohol I
used diluted bleach on the interior let it dry out reseasoned, white mold came back on the new
humidifier, mold must be below the cedar or somewhere in it.
