Why is there white dust accumulating from my Vicks Humidifier?

The white dust accumulation is likely due to using hard water in your Vicks Humidifier. Try using distilled water or a Demineralization Cartridge. It may also be caused by the Demineralization Cartridge needing replacement; in this case, replace the Demineralization Cartridge (Model PDC-51).
