Product review (5 stars): EXCELLANT!
I had called a few "big box" stores to see if they carry this filter; no luck!  I then contacted the installer of our furnace; and was told they were out; it would take about a week or more.  I then asked the price, and was told it was about $20.00.  After hearing this, I checked to make sure I was orderinf the correct filter pad; which I was.  AMAZON  was very quick on the delivery; and best of all, I paid much less for two(2) filters rather tan one!
