what else can I say? These are the manufacturer recommended filters for my oven and unlike the cardboard filters they fit perfectly. They don't greatly clean the air, but they don't reduce the efficiency of the oven by impeding airflow like MERV high-pressure filters do. The stove is not intended for air purification. If you want that, get a standalone HEPA filter. The best I can do for a complaint is too much tape holding the two filters together.
