Protec DynaFilter Humidifier Cartridge, Air Cleaning, 3 ct.
This is a replacement pack of three K14 filters for all DynaMist  domestic humidifiers. Regularly replacing the filter in a humidifier is  important: dirty humidifiers spray mildew and other irritants, don't humidify  efficiently, and fail to filter out odors and allergens. These filters also fit  Vicks CoolMist humidifiers.--Richard Farr
