Product review (3 stars): A lousy filter design robs this very good humidifier of its otherwise excellent performance and reliability
The humidifier is very well built but these filters are poorly designed.  It is virtually impossible to seat them properly in the water tray because the external webbing does not constrain the absorbent material properly or hold it in the correct oval shape.  A lousy filter design robs this very good humidifier of its otherwise excellent performance and reliability.
