The image shows a set of three different types of air filters. The filters are made of metal and have a round shape with a perforated surface. The top filter has a small hole in the center, which is likely used to filter the air. The middle filter has two smaller holes on either side, which are used to hold the filter in place while it is being heated. The bottom filter is rectangular in shape and has a diamond-shaped cutout in the middle. All three filters are black in color and appear to be made of a durable material.
