Product review (2 stars): barely functional
I am restoring Chambers range hood which is around 60 years old now.  I did not buy these for specific range hood.  They were close to the size I wanted.  The filters themselves, however, are made of layers of mesh that leaves 1/8" holes over the majority of the surface. It will quickly grease up the inner body of the hood.  I am declaring them defective and returning them.  I hope Amazon accepts this reason.  I hope anybody who must use these filters will double up the layers.
