WebHere’s why: 0.3-micron is the particle size filters are the weakest at. Pick any small particle filters, they will almost always show a higher filtration efficiency at 0.2 and 0.4-micron levels than for 0.3-microns. WebParticle size is the most important determinant of aerosol behaviour. Particles that are 5 μm or smaller in size can remain airborne indefinitely under most indoor conditions unless there is removal due to air currents or dilution ventilation. This same size range of particles (ie, <5 μm) deposits in the lower respiratory tract in humans
