Aircuity is unique because we offer a dual channel particle counter. This includes a channel between 0.3µm and 0.5µm, and a second channel which measures between 0.5µm and 2.5µm. Measuring down to .3 microns is important because:
1) Most particles are .3 -.5µm.
2) They stay airborne for a long time.
3) Filters are not effective at removing them. A MERV 13 filter is only 40% efficient with a .3 micron particle where it’s about 100% efficient with a 2.5 micron particle.
