Product review (5 stars): Good airflow, finally!
I've been needing a filter for my stove hood for years, but could never quite make myself buy one from the hardware stores because they lacked the extra filter behind the mesh.  This one has it, fits perfectly, and I can actually feel air blowing out of the top front of the hood which I haven't felt in years.  Nice to find exactly what you need online when two major hardware chains don't have what you need.
