What is Deep Media Cabinet?

A cabinet at the return holding a deep pleated media filter. The extra surface area means higher efficiency at lower resistance than a one-inch filter can achieve, and it extends the change interval to once or twice a year. Its only real constraint is physical space at the return, which is not always available in a tight closet or attic platform.
