The Optimairâ„¢ furnace filter maintains airflow and air quality by automatically advancing the filter media when dust and dirt reduce airflow through the media. The filter can be advanced manually as well. Contractors can install the filter in standard 1-inch filter slots. According to the manufacturer, installing an Optimair filter creates a protected aftermarket for contractors. The media's life lasts up to two years. The filter system is available in four sizes: 16 by 20 inches, 16 by 25 inches, 20 by 20 inches, and 20 by 25 inches.
