6 x 14 filters should 5-7/8" x 13-7/8". Despite this being the second shipment all filters are still too large. One was extremely large at 6'1/4". Pretty disappointed at the poor quality control and the hassle for the second time!
Since my furnace uses an odd size filter, it's great knowing I'm just a few clicks away from ordering new ones every few months. No more exhaustive searching of the 'net!
Good deal but I suggest putting a strip of foam tape around the sides of the filter holder to make it snug. Honeywell filters are a full 20x20 and the house brand is smaller.
