Product review (2 stars): filter held together with two beads of glue
Essick air filters HDC-12. Not well made. Paper filter material held together on one side with two beads of glue. Started to fall apart as soon as I took it out of the box. Filters look like the picture on the box and on the web site. What you don't see in the picture is two 1/8 inch beads of glue running along the back side of the filter. These two beads of glue is all that is holding the filter paper in place. Worse replacement filter yet.
