Here in Kansas, it is common and necessary to fill DC humidifier tanks twice a week or more in the winter. If the Hydrocel can supply, say 80% of the piano's needs, then it would surely help. If it can only supply 5% (three mayonnaise jars worth), it hardly seems worth the trouble for the return. Is it better than nothing? How low does the RH% get? Ron N
