Clay desiccant is the least expensive of all desiccants and is a naturally occurring non-hazardous mineral composed of magnesium aluminum silicate (a calcium aluminum silicate type of hydros clay). Montmorillonite clay is used in most industrial applications requiring humidity control because it recharges easily and does not swell as it adsorbs water vapor. Subject to a degree of variability for being a natural material, clay desiccant will adsorb approximately 25% of its weight in water vapor at 77º F and 40% relative humidity. This desiccant works well at low and room temperatures, but has a rather low ceiling temperature. At 120º F montmorillonite clay will begin to desorb or shed the moisture it has adsorbed, an important consideration for storage in hot areas. Desiccants on their own can be extremely effective, although they work better when used in combination with moisture barrier bags. Different moisture barrier bag materials come with different MVTR ratings. These ratings are extremely important, as they are the only reference point when it comes to the amount of moisture that can seep in over a period of time. Currently, the most effective moisture barrier bag material has an MVTR rating of 0.02, meaning that only 0.02 grams of moisture can penetrate the material over a 24-hour period in 95% humidity.

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 (25 degrees C).
