Mold in the Bible

Mold is NOT a new problem for humans. Read the
Bible at
Leviticus 14:45 "A house desecrated by mildew, mold, or fungus would be a defiled place to live in, so
drastic measures had to be taken.
" Mold damage, mold contamination, and mold infestation  have always been threats to people, animals, and plants. Mold Prevention is always needed. "The way to control indoor mold growth is to control moisture, reports the U.S. Environmental Protection Agency. To keep indoor humidity in the mold-safe 30-40%, use our Surround Air Dehumidifier.
