Once we will review the materials and construction. We must go on to review the humidifier. the system by which the humidity inside the humidor will be release. Compared to the complex electronic systems of large scale of cigar humidors and cellars. For personal and medium-sized ones the system is very simple. Mere covered sponges (so as not to be in direct contact with our cigars) are more than enough to control humidity. Regularly dipping these sponges in distille water. Our cigars will be perfectly preserved if the humidor is built properly.
