Experimental penetration of particles through a HEPA filter – determination that approximately 0.1% in the 0.1 micron particle range will pass through the filter. If there are 100,000 particles 0.1 micron in diameter per cubic centimeter of air, then 120 per cubic centimeter of air will pass through a HEPA filter. In one day an average man will inhale 28 million particles in the 0.1 micron range through a HEPA filter.
