Because of consumer perception, not for a technical reason.
Except for the Ultra, its metal mesh backing requires a metal end cap. The way the M&H end caps have been popping off & potentially releasing potting material, & Fram adding more pleats to the Extra Guard, fiber/engineered media end caps are doing better for 5K or less OCIs.
