The chore here is simple: you need a new hvac filter grille because the old one is cracked or the filter is slipping out. The problem is that these parts are not one-size-fits-all, and a generic guess will leave you with a gap that leaks air or a frame that will not close.
On the Amazon page, you must see the specific width, depth, and height in the product title. Do not buy based on the photo alone; the listing text must state the exact dimensions that match your measurement.
