Product review (5 stars): Perfect Match for our Broan Range Hood
Replacement grills for twenty year old Broan Microtek range oven hood fit perfectly. The finish was very similar to the original pair, which was a bright aluminum finish.  Since we got over 20 years of use with the original pair, there isn't any reason you shouldn't get at least 20 years or more, with proper care and maintenance. The range hood filters, unlike the grease filters that need to be replaced every year, can be cleaned and washed. Didn't have a chance to compare to other range hood filters, but the price from Amazon for the Broan model was reasonable and more than met our expectations.
