空气过滤介质包装、过滤器元件、空气过滤介质以及方法
摘要：
在此提供了打褶的过滤介质、介质包装、过滤器元件、以及用于过滤流体的方法，它们包括在该介质表面内的三维凹槽，这些凹槽被配置为改进过滤器性能。在某些实施方案中，这些凹槽具有降低相邻的褶之间掩蔽的多个定义的峰，这些凹槽具有沿着其长度的多个脊以改变凹槽的横截面几何形状，和/或这些凹槽提供了贯穿该介质的体积不对称性。
摘要（英）：

Pleated filtration media, media packs, filter elements, and methods for filtering fluid are provided which contain three dimensional flutes in the media surface, the flutes configured to improve filter performance. In certain embodiments the flutes have defined peaks that reduce masking between adjacent pleats, the flutes have ridges along their length to modify flute cross sectional geometry, and/or the flutes provide for volume asymmetry across the media.
