Product review (5 stars): Great OEM Range Hood Filter
The filter fits perfectly into my Nutone 43000 series range hood.  It is of high quality with a carbon sheet behind the aluminum filter elements.  The filters were shipped by Surplus Supply which had great customer service because USPS damaged the initial order during shipment.  When I contacted Surplus Supply by emailing them a picture of the damage caused by USPS, they sent a replacement order immediately.  I will definitely continue to do business with this vendor via Amazon again!
