To ensure a properly functioning Humidifier, the Pads and Clean Sleeve should be changed twice each year, and the Water Tank Liner annually. This package includes 4 Humidifier Pads, 2 Clean Sleeves, and Tank Liners (Universal and Pre-Universal) for Annual Maintenance. Includes Instructions.

Humidifier Pads: Lightweight, durable, and highly absorbent with antimicrobial properties and a low lint level to help control residue buildup on sensors. They wick water across the Humidifier Heater Bar to bring moisture into the piano. If the pads are caked with mineral deposits or hardened on top, the Humidifier will not be effective. Tank Liner: For lining the inside of the Water Tank for protection and easy maintenance. Clean Sleeve: Covers Humidifier Heater Bar for easy maintenance.
