What is the difference between pleated and disposable filters?
A. Disposable filters are made of low efficiency fiberglass with a cardboard frame around the perimeter. These are often referred to as “furnace filters” due to their most common application. Pleated filters are made of a medium efficiency synthetic media which is pleated to increase the surface area within the filter. This media is then glued into a die-cut frame made from moisture resistant paper board.
