The steam humidifier has just one part that requires periodical replacement:
WKHVWHDPSURGXFWLRQF\OLQGHU
.
This operation is necessary when the lime scale deposits that form inside the cylinder prevent the sufficient passage of

supply water: the higher the content of salts or impurities, the more frequently the cylinder will need replacing.
