I haven't installed the ones I just received but have used these previously.We are very satisfied with them and my wife has noticed an appreciable reduction in dust accumulation.
they fit exactly as you said, however I expected them to be white instead of yellow. I have many allergies will that yellow tint have any long term effect on the quality of air coming into the house?
Filter media looks good but cardboard framework was not of full dimension. Not sure if this was a manufacturing or shipping problem. Makes for a poor fit in the filter holder with air gaps on the sides
