Product review (4 stars): Good quality replacement frame
This is about the same quality as my original Aprilaire filter frame.  My original frame lasted about 10 years before it developed cracks where it attaches to the tray.  Although this new one is black (my original frame was clear/translucent) it appears to be about the same quality of material.  If it lasts another 10 years, I guess I'll be happy.
