The grease filter is intended for use with some downdraft cooktops and ranges to collect grease particles in the air from cooking. The grease filter is silver in color, approximately 15 1/2” long and almost 6 1/4” wide. As per the manufacturer, the original filter may have been a 1/2” wider, but it should not be a problem and will still function the same. The grease filter is sold individually and is a genuine OEM part.
