To ensure a properly functioning Humidifier, the Pads should be changed twice each year, and the Water Tank Liner annually. This package includes 4 Humidifier Pads and 1 Black Universal Tank Liner 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.
