What is the best way to tell if an air purifier is really improving my Indoor Air Quality?
The Gold standard for scientifically and objectively measuring the efficiency of an air purifier to reduce the amount of airborne particles is to measure the pollution level of your indoor air with a laser particle counter (LPC). The laser particle counter is an instrument that measures airborne particles floating around in the air by shining a laser through the air. Particles then block the laser and prevent it from being detected by the special detectors whereby a number is then calculated by the LPC to indicate the level of airborne contaminants.
