Product review (5 stars): Works like a charm
Works like a charm.  We got tired of the smoke alarm going off in the kitchen when cooking certain foods.  I'm a DIYer and since we already have plans to remodel the kitchen in the near future, I started planning to run ductwork through the cabinet and then ceiling and boxing the duct work in drywall.  Then it dawned on me that our type of hood is meant to ventilate into the kitchen (growing up my parents always had a vent that ventilated to the outdoors).  Decided to search for a filter, and sure enough, I found that they are readily available.  I ordered three of them.  Changed the old nasty one out and now I can fry food and my wife can burn food (haha) without the smoke alarm going off constantly.
