Cigar humidifiers are all that stand between your precious cigars and the environment outside of your cigar humidor. Without an appropriate humidifying device, even the best humidor doesn''t stand a chance of maintaining your cigars'' moisture content properly. There are two main types of humidifying devices: active and passive. Active devices - typically comprising a reservoir, circulation fan, and hydrostat that add moisture as needed - are usually a good fit for larger humidors. Passive devices - typically made of a sponge-like material which releases moisture as it evaporates - are usually a better fit for smaller desktop and personal humidors.
