The top of some filters cracked during insulation, the plastic is very thin and the overall height of the filter changes so they break when I tighten the filter. So far this has been done with two filters and now I'm bringing them up to select the shortest ones. I'm not sure if this is due to improper assembly, a crooked top or bottom, or improperly cut cone material. They really last a long time and if they didn't break they would be very valuable.
