Odors most often indicate the presence of bacteria in the water reservoir or filtering system. To kill the bacteria, clear the unit with a solution of 1 tablespoon of chlorine bleach per pint of water or use an antibacterial cleaner recommended by the manufacturer. Then rinse thoroughly with plain water.

A squeaking or slow-turning fan can often be cured wuth a few drops of oil. Lubricate the bearings on the fan motor with a few drops of non-detergent SAE 20 oil at least once a year. Some units require additional lubrication to ensure quiet and efficient functioning. Check the owner’s manual for your unit’s lubrication schedule and recommended lubricants.

Some humidifiers contain a frost valve to maintain the proper water level. If the valve gets stuck because of mineral deposits then clean it with a vinegar-water solution and scrape away any buildup. If it can’t be cleaned or appears worn, replace the float valve. Adjust the valve for the proper level.
