1, It provides up to 25 percent more filtration air flow than other same-sized cartridge.
2, Shorter and stiffer filter pleats help minimize dust entrapment simplify filter
cleaning. By reducing the height of the pleats from the standard 2 inches to 1.5
inches, the pleat wall is less likely to collapse or bend, which can encapsulate
dust and prevent it's expulsion. Meanwhile cost was reduced.
3, Oval-shaped cartridge filters have fewer areas of high velocity, resulting in
a lower potentially for media abrasion and increased filter life
