Our cigar humidor humidifier products are available in a variety of types. At Vanderburgh's we have a special humidity fabric, made of a revolutionary synthetic material, that maintains a constant RH of 65 percent in an enclosed environment. We also supply cigar humidor humidifier beads which provide a virtually maintenance free solution for humidification. The fabric we use is extremely durable and tear resistant. This cigar humidor humidifier fabric can condition about twenty two cubic inches per square inch of fabric. For instance, if you had a 10 x 10 x 10 inch square box, you would require forty five square inches of fabric sheeting. This would give you more than enough fabric to control the RH of your cigar humidor humidifier to 65 percent.
