A sock style filter is disclosed that incorporates the embossing of filtration media to create rigid raised geometry embodiments that prevent collapse between the upper and lower filtration media sides of the filter to maintain and ensure a flow passage of fluid inside the filter for flow to the pump or downstream system. The embossed rigid embodiments keep the filtration media from collapsing under suction and eliminates the use of secondary inserted structures; such as a plastic comb or folded net, or injection mold plastic ribs or bones onto or around the filtration media. 公开种滤袋式过滤器，其结合过滤介质的压花以生成刚性隆起几何结构的实施方式，所述实施方式防止过滤器的上下过滤介质侧之间的坍塌，从而维持且确保在过滤器内的流体的流动通道以流动到泵或下游系统。被压花的刚性实施方式防止过滤介质在抽吸下塌陷且消除辅助插入结构的使用；诸如在过滤介质上或围绕过滤介质的塑料梳或折叠网、或注射成型的塑料肋或骨。
