Product review (5 stars): Fits perfectly
This air filter replaced one that was probably 50 or more years old. It is so nice to see it there in the exhaust fan above my kitchen stove. My kitchen is an oldie but goodie and suits me just fine. There are no wasted steps and no wasted space. It's purely for function and efficiency, and everything is kept in tip top working order. I can get almost everything I need on Amazon.
