Product review (5 stars): Excellent Product Makes Breathing Better!
When we bought our humidifier, it contained the wrong filter!  This Holmes HWF64 filter is a perfect fit and simple to install.  Even at low speeds, the humidifier quickly fills our large (14' x 22') bedroom with enough moist air that I can breathe easily.  If you have allergies and/or asthma (I have both), you will find that this filter helps you get a better night's sleep.

Shipped promptly, no defects, no hassles!
