Conventional HVAC filters rely on only two or three filtration effects, but the NanoMax filter optimizes five different filtration effects. This combines maximum air cleaning efficiency with minimal air resistance.
Straining Effect. This effect captures very large particles that are simply too large to fit in between filter fibers. Capture Range: Larger than 100 microns
Impingement Effect. Larger particles collide with fibers, becoming attached. This includes mold spores and pollen. Capture Range: Larger than 10 microns
Interception Effect. Smaller particles are captured as they come within half a particle diameter of the fiber. Capture Range: Smaller than 10 microns.
Electrostatic Attraction: The electrostatic charges of fibers help attract and capture smaller particles. Capture Range: Smaller than 10 microns
Diffusion. Very small particles (ultrafine particles) are bounced around by air, eventually colliding with filter fibers. Capture Range: Smaller than 0.1 microns
