Product Review

These desiccant packs are ideal for knocking down humidity in 5-gallon food storage buckets. After depletion they may be reactivated by heating in an oven. These are Food/Pharmaceutical grade.

Desiccants are packaged in "Units" sometimes abbreviated by the letter "U". A Unit of desiccant refers to its drying capacity, not its volume. A Unit (approximately one ounce) is the amount of desiccant that will absorb at least three grams of water vapor at 20% relative humidity and at least six grams of water vapor at 40% relative humidity at 77 degrees F. Each of the packs in this item contain 1 Unit of desiccant.
