Piano Lifesaver
A Piano Life Saver is a humidity control system for your piano. It will help your piano stay in tune and will protect against the long-term damage caused by humidity fluctuations. These systems are recommended by almost all major piano manufacturers. They are installed out of sight, make no sound, and require only minimal maintenance by the piano owner.
