Abstract

Versions of the invention include a pleated filter with a repeating pattern of primary and at least two types of secondary pleats. The repeating pattern of primary and the secondary pleats has improved resistance to flow deterioration or flow loss compared to traditional M-pleated filters with only a single type of secondary pleat.
