Product review (4 stars): Make sure that they are authentic
Be sure to confirm with any seller that you are ordering an authentic Broan S97007696 or OEM filter. Broan has confirmed that their S97007696 and 41F (bulk pack) filters are blue in color as pictured. They further said that they don't package their filters in the manner in which mine was packaged. I can only conclude that many sellers are substituting less expensive, generic filters for the Broan's. The one that I received was black and also thinner than the Broan filter that I was replacing.  It might work for you, but it didn't for my application.
