What is PM2.5?
Particulate matter (PM) 2.5 refers to fine particles in the air that have a diameter of 2.5 micrometers or smaller. These particles are extremely small and can remain airborne for long periods, making them easily inhalable. A piece of copy paper is approximately 100 micrometers thick. That is, approximately 40 times the thickness of a particle found in the PM2.5 category.
How does it affect me, and how can I manage it?
PM2.5 is a common air pollutant that can originate from various sources, both natural and human-made. It can be found in the air, as a result of combustion, construction, and other similar activities. Increased PM2.5 has significant implications on human health, such as exacerbating heart or lung disease, aggravating asthma, and diverse health effects for those with existing conditions (especially children and older adults).
PM2.5 can be managed in a number of ways. Although HVAC units in your buildings can help reduce the levels of these particles, you can also stay on top of proper ventilation, air filtration, and regular cleaning.
How is it measured?
PM2.5 is measured in micrograms per cubic meter (µg/m3). The WELL Building Standard in Abound for PM2.5 is set to less than 12 µg/m3.
