  If your HoMedics Humidifier is not producing mist and seems to have no power, there are several things to check: * Ensure the unit is properly plugged into a working outlet. * Make sure the power button is turned on. * Examine your circuits and fuses, or try a different outlet to rule out power issues. * Check the water level and refill the tank if it's low. * Clean the transducer/ultrasonic membrane following the instructions in the Cleaning and Care section. * Verify the float is correctly installed.

  If you notice a white dust accumulating from your HoMedics Humidifier, it's likely due to using hard water. To resolve this, switch to distilled water and use a demineralization cartridge. If you're already using a cartridge, it might be time to replace it with a new one.

  If your HoMedics Humidifier has a peculiar odor, especially when new, remove the tank and let it air out in a cool, dry place for about 12 hours. If the unit is already in use, the odor may be due to a dirty tank or old water. Empty the old water, clean the tank thoroughly, and refill it with clean water.
