The Cigar Oasis Electronic Humidifier Refill Water Cartridge with Battery Pack fits both the Cigar Oasis and Cigar Oasis XL units. Each cartridge contains a foam core element combined with distilled water and an antifungal agent for optimal cigar preservation. This unit is the same cartridge as the short refill cartridge but includes a battery pack that clips on and attaches to the electronic Oasis control unit. The battery operation enables the Cigar Oasis to run without the need of an AC outlet. Need to take your humidor in your vehicle, on a boat, etc? The new Cigar Oasis Water Cartridge with Battery Pack is the perfect solution.

The fan in the electronic control unit extracts air from inside the humidor and directs it through the cartridge which "charges" the air with moisture. The Cigar Oasis unit then emits the humidified air into the humidor and is then absorbed by the cigars. The amount of time water is consumed will depend on the dimensions of the humidor, how well the humidor is sealed, and the condition of your cigars. On average, a refill cartridge in a well constructed humidor with 75-125 cigars that is opened 3-5 times a week could last as long as 9 to 12 months.
