These are great filters, I

These are great filters, I replaced my heating/air system and the new one requires 4" filters. These fit perfectly and do a great job. I will be buying again.
The sizes are not exact, which makes them about a 1/2 inch smaller than the full opening (in height). I wish they were more accurate in the size. They still fit, but have a small gap at the top. On my last shipment, a few of the filters were dented and one of the wrappers was broken open. Other than that, they work very well.
Very undersized. Had to add filler strips to keep air from flowing around the filter. Kind of defeats the purpose of using a high filtration filter if the air just bypasses! Compared to my old Honeywell filter, smaller in all directions. Not worth the lower cost. Makes me very suspicious if Merv rating is also substandard.
The quality of these is horrendous. Looks like the first four that ever came off the line. Fabric sticking out of the frame, not adhered to the side, wire mesh all bent out of shape, pleats all jammed together. The only 'MERV 13' thing about these is the fabric. The way they put them together will never allow it to perform.
The quality and price are great, but the smaller measurements are problematic. The 20x20x4 (actual measurement 19 3/8 x 19 3/8 x 3 5/8) balances precariously in the slot it's meant for, I have to keep checking to make sure the airflow hasn't knocked it off kilter. The name brand I've used previously fits snuggly.
