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 machine operates very quietly but it is not completely silent. Noise levels less than 

25 db is considered normal. 

WARNING! 

If the above recommended solutions do not work, please contact 

Clean Air Optima

 technical 

support at the telephone number for your region. Do not attempt to disassemble, repair 

and reassemble the machine as it may void the warranty
