| 摘要 |
The disclosure includes, in some embodiments, a filter element that includes a first porous outer layer formed from a nonwoven material, a second porous outer layer formed from a nonwoven material, and at least one inner porous layer formed from a high loft nonwoven material (or other suitable material) disposed between the first porous outer layer and the second porous outer layer. The high loft nonwoven material has a three dimensional matrix formed by entangled and bonded fibers that cooperate to form a plurality of three dimensional interstices between the fibers for maintaining an open and tortuous flow path for fluid to pass through. The filter element also includes filter aid particles dispersed in the interstices of the high loft nonwoven material. |
