Product review (5 stars): Love the unit after two small issues. Broan was great!
We recently bought the Broan AP130SS hood and needed to recirculate the air so naturally we bought this.  After a bit of tinkering, we absolutely love this and the hood. I'll review the hood there, here's just the information about this unit.

We did have two items that needed to be addressed.  One, the electric connection.  I had installed an outlet and had a cord to connect to the hood, but there was no place to pass the cord through the top of this unit.  I ended up drilling a hole into the top of this unit, right above the knockout for the cord from the hood.  Problem solved.

Second was the filters and this threw me for a bit.  The instructions here simply state to put the aluminum filters from the hood into the bigger, plastic holder filter and then simply 'install these filters with the aluminum filters facing out'.  I couldn't figure this out as the plastic ones didnt' fit.  At first we just pushed them into place and compression was holding them, but I knew that couldn't be right.  I contacted Broan and at first all they did was send me the same instructions I had.  I asked for further clarification and they sent me four photos and that finally hit home.  What you have to do is slide the aluminum filters into these plastic holders like the instructions state.  Then bend the plastic trim around the aluminum filters to they become almost molded to the original filter.  You might have to work the plastic a little to get it to bend that much.  Then, slip the top part back into place, while bending the sides of the plastic around the filter still, and lift into place.  Basically, these fit just like the aluminum filters only, but now much tighter with the plastic trim.

Now it's awesome!  Love it.
