The filter seemed to be of acceptable quality for the price, but it didn't fit snugly in my system intake; it was too tight. Of course, although they're labeled as 14 inches wide, they're only 13.5 inches tall. They basically barely covered the intake, but I had to position them very carefully before closing the vent, and I have some concerns that air could get past them on the sides, bringing dust and such into my system. . Too bad. They seem good enough for the price but I won't buy them again.
