These air filters are built to last, offering long-lasting filtration performance. You can use this air filter media in Air Bear Supreme, Right Angle, and Cub filters with accommodating sizes. The actual dimensions for this replacement filter are 19.75 inches tall, 24.25 inches wide, and 4.94 inches deep. (size does not include a 0.25-inch gasket located along the top and bottom edges of the filter). Not all filters are created equal. To ensure this is just what you need, we recommend checking measurements before ordering. Trap dirt, dust, pollen, pet dander, and other airborne particles as small as 1 micron in this air filter. This high-efficiency air filter is MERV 11 rated with electrostatically-charged synthetic filter material. The non-woven, 5-inch thick, pleated filter media retains its shape even when dirty or when air pressure drops, guaranteeing that the filter captures as much dirt and dust as possible. The factory-installed double gasket eliminates the need for a filter bypass. Say farewell to airborne contaminants and experience a healthier, more comfortable living environment.
