The Cigar Oasis EXCEL 3.0 is a small, fully automatic humidifier. Just plug it in using a paper thin power cord and it's ready to go. The large LCD displays the humidity and temperature in the humidor and displays the current set point.
The unit comes with a refillable, replaceable water cartridge that uses distilled water only. The Cigar Oasis EXCEL 3.0 has a build in the system, which accurately monitors the humidity and uses a quiet fan to filter and circulate the air in the humidor eliminating "musty" odors so common in well-sealed humidors. The Cigar Oasis EXCEL 3.0 has built-in Smart Humidor® Wi-Fi which allows users to adjust and monitor humidity remotely from any iOS or Android smart device (optional subscription).
