Aren viruses too small to be captured by the high efficiency filters?
The HEPA filters are rated according to their ability to remove particulates measuring 0.3 microns, an industry standard. Because of the way these filters are designed, their efficiency actually increases for particles both smaller and larger than the most penetrating particle size, which is about 0.1 to 0.2 microns. The efficiency of HEPA filters to remove bacteria and viruses (.01 to .1 microns) is greater than 99 percent.
