Ok cigar smokers, how many of you have once forgotten to re-soak your humidifiers and have dried out a good box of cigars? Sound familiar? If you are anything like us, keeping up with a well seasoned humidor is not easy. Now you can reduce or eliminate the number of cigars that are damaged by fluctuating humidity conditions. No more re-soaking your humidifiers! The humidity in your humidor can now be automatically controlled and completely maintained through the cigar oasis plus electronic humidifier. This highly reliable system has exceeded our customers' expectations and keeps their cigars fresh day after day maintenance free. Introducing the new cigar oasis plus 3.0 electric humidifier for mid-size humidors. Guaranteed to keep your cigars fresh day after day! The cigar oasis xl plus 3.0 electronic humidifier is designed for large desktop humidors, cigar end tables, chests and other cigar enclosures which house from 300 to 1000 cigars (up to 10 cubic feet). It is based on the same exclusive cigar oasis technology and uses the same small 6" w x 2" l x 3.5" h structure. The difference is that the plus model distributes its moisture through the use of a more efficient water cartridge that allows for increased airflow delivering more humidification/moisture to achieve the desired humidity level. Operation: the cigar oasis plus carries a near identical appearance to the renowned cigar oasis excel, however, improvements to its airflow characteristics have been altered to allow for greater air circulation. Simply place the cigar oasis plus 3.0 inside a closed humidor enclosure and air will begin to be drawn in to the inlet vents of the oasis control unit. The air will then be channelled into the attached water cartridge where it is then "Humidified" and released into the humidor. The greater air circulation ability of the cigar oasis plus 3.0 humidifier provides for ultra-fast humidity regulation within your humidor. The unit is factory set at 70% rh, but can be adjusted to your own personal preference. Once the desired humidity level is reached, a unique sensor monitors and insures that the humidity stays fixed at that set level. If you open your humidor and the humidity drops below the setpoint, the oasis sensor will trigger the fan to bring humidity levels back to the specified preset. The plus 3.0 now has a built-in smart humidor® wi-fi which allows users to monitor and adjust humidity from anywhere using any apple ios or android smart device with a subscription. The cigar oasis plus 3.0 electric humidifier accurately measures and reliably controls the humidity in your humidor.
