Product review (1 stars): Vertical Stitching Unraveled
The Honeywell filter material appears to be of a better quality than the off brand filters I've used. But the vertical stitching that holds the Honeywell filter in its cylindrical shape became unraveled in a couple of days. Now instead of the filter standing up, it lays limp in my humidifier, making it virtually useless (and very difficult to close the humidifier component over it). See photo.
