KEY TO K&N PERFORMANCE
4 LAYER
COMPOSITE
FILTER MEDIA
- Built for Strength & Support
- Blocks Dust Before It Builds
- Captures Microscopic Debris
- Keeps Filters in Perfect Form
K&N’s performance stems from its proprietary 4-layer composite media. This advanced design ensures high filtration efficiency, low resistance, and hydrophobic properties, enabling washable filters that maintain peak performance without compromise.
+10μm PARTICLES
INITIAL SPUNBOND SUPPORT LAYER
Initial support layer where big, charged particles are screened off.
- Strong tensile strength layer provides superior pleating & support.
- High permeability, but creates initial filtration layer – protecting from large/charged particles.
- Hydrophobic fiber coat has very good washing properties.
2-10μm PARTICLES
ELECTROSTATIC PREFILTER PROTECTION LAYER
Blocking layer effective at trapping greater than 2 micron particles. These very fine fibers are densely packed, combing the air, and trapping particle.
- Serves as an upstream blocking layer protecting downstream layers from large particles.
<2μm PARTICLES
ELECTROSTATIC FILTRATION FUNCTIONAL LAYER
Larger fibers with medium density channels allow the air to flow with turbulence, trapping particles less than 2 micron.
- High-loft, thicker electrostatic layer provides maximum filtration with high permeability.
- Unique materials in each MERV variation and varying thickness drive filtration efficiency.
SECONDARY SPUNBOND SUPPORT LAYER
Backing support layer working to provide shape & rigidity.
