Product review (3 stars): Much Worse Than The Original Filter
The original HC-14 filter that came with the humidifier had a blue outside layer that provided additional strength and filtration.  Honeywell discontinued that filter and replaced it with this one that doesn't have the outer layer.  Although the filter seems to function adequately, it falls apart quickly.  I've had one come apart at the seam in less than a week, and a replacement is about to do the same.  Also the filter material tends to shred and disintegrate.  I'm going to try aftermarket filters since Honeywell is no longer producing a quality product.
