Negative Positive
Title: A waste of money
Review: This is supposed to filter the air on an Essick Air H-series console humidifier. In fact, it actually blocks the air to the unit and makes it much less efficient. It's an optional attachment to the unit and is completely unnecessary unless you live in a really filthy environment -- like maybe in a coal mine. Listen, we have three cats and I never saw any cat hair in the filter. The filter never got dirty. Does this tell you something?
