The following is not considered faulty operation:
• If your water is very hard (containing abnormally high levels of minerals) the humidifier may produce white dust. This is not a malfunction. The solution would be to clean the filter more often or use softer water.
• If you stand very close to the humidifier, you will hear the gurgling sound of water.
This is normal.
• The humidifier operates very quietly but it is not completely silent. Noise levels less than 35dB(A) is considered normal.
