Cigar Oasis developed active humidifiers to meet the need in the cigar industry for a better way to keep cigars fresh. The use of a special ribbon cable allows the humidifier to use AC power and still have the humidor create a perfect seal. The humidity sensor measures the humidity and when the humidity drops below the desired set point, the microprocessor turns on the fan. When the fan is on it draws air from the humidor, humidifies it, and puts it back into the humidor to bring it back up to the set point when it will turn off. While blowing humidity into the humidor, the units also allow for air movement in order to maximize the freshness of the cigars. Cigar Oasis is the original sealed humidifier.
