Product review (5 stars): MoistAir-Essick Air HDC-12
Essick Air Products manufactures and markets the HDC-12 MoistAir humidifier filter. Essick also is a manufacturer of humidifiers. A handfull of Kenmore humidifiers also recommend and use this filter, Kenmore No. 14911. The two part numbers will give you the same filter which is a "paper-pleated type'. Anything other, such as the spongy foam type offered by other manufacturers, is *inferior* in performance. Beware of misleading info fooling you out of the real McCoy. The foam type filters or wicks may be obtained for half the price but require replacement 3 times as often if not more.
