TECHNOLOGY EFFECT
Improving indoor air quality through an air purifier able to reduce aerosol particulate matter (PM) and volatile organic compounds (VOCs): Experimental Results
The adverse effects of fine particulate matter and many volatile organic substances on human health are well known. Fine particles are, in fact, those most capable of penetrating in depth into the respiratory system. People spend most of their time indoors where concentrations of some pollutants are sometimes higher than outdoors. Therefore, there is the need to ensure a healthy indoor environment and for this purpose the use of an air purifier can be a valuable aid especially now since it was demonstrated that indoor air quality has a high impact on spreading of viral infections such as that due to SARS-COVID19.
In this study, we tested a commercial system that can be used as an air purifier. In particular it was verified its efficiency in reducing concentrations of PM10 (particles with aerodynamic diameter less than 10 μm), PM2.5 (particles with aerodynamic diameter less than 2.5 μm), PM1 (particles with aerodynamic diameter less than 1 μm), and particle number in the range 0.3 μm -10 μm.
Furthermore, its capacity in reducing VOCs (Volatile Organic Compounds) concentration was also checked. PM measurements were carried out by means of a portable optical particle counter (OPC) instrument simulating the working conditions typical of a household environment. In particular we showed that the tested air purifier significantly reduced both PM10 and PM2.5 by 16.8 and 7.25 times respectively that corresponds to a reduction of over 90% and 80%. A clear reduction of VOCs concentrations was also observed since a decrease of over 50% of these gaseous substances was achieved.
PARTICULATE MATTERS
Particulate matter, or PM, is the term for a mixture of solid particles and liquid droplets found in the air, whose major components are black carbon, sulfate, nitrates, ammonia, sodium chloride, mineral dust, and water. A synonym for particle matter commonly used when particles occur together with gases is aerosol.
