Product review (5 stars): Works with my generic Nutone hood, good quality, lower price than Home depot
It fits perfectly into my basic Nutone hood.  I still recommend measuring the size of your old one and making sure it's close to the same size.  What I like most:

1. Cheaper than Home Depot, and then, Home Depot would have to order.  (I don't know why Home Depot doesn't just stock them)
2.  Cheap price, easy to replace, so I don't have to TRY to clean.  (I tried every way possible to clean the old one, because I thought they were "cleanable".....did all the internet tricks.  You CAN'T clean them.......just buy a new one and a spare at this price.
3.  It was welled pack and shipped superfast
4.  The quality was exactly the same as what came in the hood originally (these are not rigid, that doesn't not mean they are inferior.  The quality is just fine, once installs it does a good job.)
