Micron
A unit of length in the metric system equal to one millionth of a meter (1 micron = 1 μm or 0.000001 meters). It is commonly used in HVAC contexts to measure the size of airborne particles, such as dust, pollen, mold spores, and viruses. These particles, described in microns, can affect indoor air quality. For perspective, a human hair is about 50 to 70 microns in diameter. Managing particles of this size is essential for maintaining healthy and clean air in your home.
