Hi - great product however the overall height of the filter is just under (<1/4") the Honeywell filter equivalent. This creates a gap at the top of the filter that allows unfiltered air to pass by. I had to place a filler to close the gap at the top. Future filters should have an extra flap or piece of material to fill that gap.
Filters don't appear to be as good quality as what I have purchased elsewhere in the past. Not as sturdy frame or as many pleats as what I have used before. Just started using them so not sure how well they work yet. Hpwever, they were less expensive so possibly got what I paid for.
