The Cigar Oasis PLUS 3.0 humidifier is powerful, compact, and ideal for small cabinet, end table, or coffee table humidors. The PLUS 3.0's specially configured airflow system and water cartridge allows the unit to efficiently pick up more moisture and provide faster humidification to large capacity humidifiers. The PLUS 3.0 comes with the built-in Smart Humidor® Wi-Fi technology that lets you adjust and monitor the humidifier's humidity levels from any iOS or Android device (subscription required). Fully automatic, the PLUS 3.0 is preset to keep your humidor’s moisture level at 70%. The PLUS 3.0's quiet, yet powerful fan evenly circulates the air in the humidor thereby eliminating the need to rotate cigars. Never worry about running out of water with the Low Water Alert system that is available on both the unit and the app. Low maintenance, the PLUS 3.0’s water cartridge is pre-treated and prefilled, and it only needs refilling with distilled water every 1 to 3 months. Perfect for up to 1000 cigar capacity humidors (up to 10 cubic feet). Dimensions: 6"L x 2"W x 3.5"H.
