Humidifier emits unpleasant or musty odor during operation

Safety: Unplug the humidifier and empty the water tank.

Steps:

• Deep clean tank: Wash the tank with warm water and mild detergent. Rinse thoroughly. Disinfect with a solution of 1 part white vinegar to 3 parts water; let sit 20 minutes, then rinse.
• Clean base: Wipe the base reservoir and all water-contact surfaces with vinegar solution. Avoid soaking electrical components.
• Replace wick/filter: If your Sencor model uses a wick or filter, replace it according to the manual.
• Use fresh water: Always refill with fresh, preferably distilled water. Empty the tank if the unit will not be used for more than a day.
