Dampp-Chaser Piano Life Saver System

The Dampp-Chaser Piano Life Saver System is the most effective acoustic piano humidity control system available, used by piano technicians worldwide to protect acoustic pianos from the wood warping, tuning instability, and action regulation problems caused by seasonal humidity fluctuation. The system consists of a humidifier that adds moisture when the internal piano environment falls below 45% relative humidity and a dehumidifier that removes moisture when it rises above 50%, maintaining the piano's internal environment within the 45-50% RH range that acoustic piano manufacturers specify as optimal for longevity.

• Maintains 45-50% relative humidity — manufacturer specified optimal range
• Humidifier and dehumidifier — works in both directions seasonally
• Protects from tuning instability and action regulation problems
• Used by piano technicians worldwide
