Hence the larger the particle, the higher a HEPA filter filters out the particle? Not so quick! Did you recognize the dip in the final graph? That takes place mainly because diffusion performs really well less than about 0.3 microns. Where Individuals two mechanics intersect is the toughest particle size to seize.
