This will be about Paradigm Humidifiers. Paradigms have a special medical foam that holds a lot of water, and the foam also has an anti-mold treatment. While designed to keep your humidity at the 70% level, there are some tricks to adjust the humidity up and down. If you are using one in a large humidor, and its not getting the humidity high enough, try removing the end caps. This will expose more foam, and boost your humidity. If you want to lower your humidity level, partially cover the side vents with some electrical tape. This will expose less foam, and lower the output of the humidifier.
