Product review (5 stars): Stop Cleaning Your Filters and Buy These!
The filter dimensions were exactly what I needed for my 5 year old Broan oven hood.  These are third party filters, but the price was definitely cheaper than trying to find original equipment manufacturer parts for presumably for the same quality.  I contacted the manufacturer to ensure it would be as effective as the original Broan filters as they were identical on one side, but not on the air intake side.  I was assured that they would be as its sole purpose is to keep the grease from entering the fans and inhibiting performance.

I have already tested the durability of the frame as one side of my oven hood is a rather tight fit and I had to squeeze and pull to get it into place, the same strategy I use to get the original back into place after cleaning it.  The frame held up nicely after that debacle and occupied the same footprint as the original.  I'm extremely grateful that I won't have to clean the original filters any longer, as it's much cheaper to replace with these quality filters.  The original ones never came clean, even after soaking and a couple rounds in the dishwasher.  I knew there had to be a better way and I'm satisfied with the quality, durability, and the dimensions.
