Pianos are very susceptible to changes in humidity. Too much humidity is a bad thing, as is not enough humidity. A Piano Life Saver System controls the Relative Humidity in and around the Piano, keeping the environment at the ideal levels.
Too much humidity can also cause sluggish keys, rust in the center pins(action hinges), and in extreme cases, mold and mildew.
