With the overwhelming success of Cigar Oasis as the best humidifier available, our customers demanded a unit for larger humidifiers such as display cases, armoires, end tables etc. Our answer was Cigar Oasis II XL using the new microprocessor technology -same as Cigar Oasis XL- with a larger refillable distilled water reservoir. The distilled water reservoir in the lower section is ready to operate once you fill with water and plug it into power. A unique sensor measures accurately the humidity in the humidor and the signal is used to operate a control fan which returns the humidified air back to the humidor. A second set of fans are included with every unit which are on all the time to assure that air is always moving in the controlled space. If it is a large cabinet provision is available for an auxiliary fan with extended wires to be located at a suitable location in the cabinet to move the air and avoid gradients. The unit filters and circulates the air inside the humidor and recovers rapidly to the controlled humidity after accessing the humidor. Cigar Oasis II XL is the reliable way to make humidification easy and guarantee that your cigars are always fresh. Cigar Oasis II XL is shipped with a foam which is treated with an antifungal agent and the user must fill the water reservoir containing the foam with distilled water only. The foam is a large block and will last for 2-3 years and replacement blocks are available.
