Cigar Oasis Plus 3.0. The Cigar Oasis PLUS 3.0 is the newly redesigned electronic humidifier that is fully automatic. The Cigar Oasis PLUS 3.0 comes standard with a large water cartridge, which uses foam to eliminate water splashing around. The large LCD displays the humidity and temperature in the humidor and also displays the current set point. Cigar Oasis humidifiers are factory set at 70% RH, but can be adjusted to your own personal taste. The user may refill the water cartridge according to the manufacturers’ instructions with distilled water when the indicator flashes “H2O”. The Cigar Oasis PLUS 3.0 has a built-in system, which accurately monitors the humidity and uses a quiet fan to circulate the air in the humidor eliminating “musty” odors so common in well-sealed humidors. A new addition to Cigar Oasis electronic humidifiers is that the PLUS 3.0 now has built-in Smart Humidor® Wi-Fi which allows users to adjust and monitor humidity remotely from any iOS or Android smart device with a subscription.
