How Does the Laser Egg Measure ? - Kaiterra

Measuring is vital because of the impact it has on our health and the ability that it has to penetrate deep into our bodies. refers to particulate matter in the air with an aerodynamic diameter equal to or smaller than microns. Only by measuring can we start to understand the levels that we are exposed to and ultimately work towards fixing it and improving our air.
