Prestige Import Group Cigar Oasis Excel Refill Cartridge for Humidors

The Cigar Oasis Excel refill cartridge provides controlled humidification for desktop and small cabinet humidors. Its sealed cartridge design simplifies replacement and reduces maintenance compared with loose sponge systems. The cartridge maintains stable humidity for weeks under normal storage conditions to protect cigar flavor and burn. It is compatible with Excel-series humidifiers and many desktop humidor housings for broad usability. Installation is tool-free — slide the cartridge into the humidifier housing and allow it to equilibrate. The cartridge is constructed from inert, durable materials that resist mold and minimize odor transfer. Scheduled replacement restores optimal humidification performance and helps preserve cigar condition. Use distilled water and follow manufacturer replacement intervals for best results.
