Product review (5 stars): Perfect fit
These Broan filters fit our existing range hood perfectly.  We kept the aluminum outer filters and simply put them in our dishwasher to clean them.  Then easily attached these replacement filters to the aluminum filters and reinstalled them.  Our range hood is not used that often.  The original set of filters lasted 20+ years, so I thought finding replacements for such an old appliance was going to be tough.  Happily, not the case.  The old model numbers matched up with the new items and compatibility was identical.  Very pleased!
