What are the individual pollutants measured and how will they affect the IAQ score?

PM2.5 - PM stands for particulate matter (also called particle pollution), the term for a mixture of solid particles and liquid droplets found in the air you can breathe. 2.5 is a measurement for the fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Breathable air particles can include: pet dander, bacteria, mold, chemicals from cleaning products, building materials, fuel-burning equipment such as furnaces, upholstered goods, cooking, sweeping, copy machines, skin flakes, clothing fibers, combustion, cooking, smoke, dust, dirt, spores, pollen. Sources vary seasonally.

CO2 - (also known as carbon dioxide) is an odorless, colorless, non-flammable gas. CO2 is a byproduct of combustion, as well as a result of the metabolic process in living organisms (for example, you remove it from your body via the lungs in exhaled air).

VOC - (also known as volatile organic compounds or chemicals) are a combination of gases and odors released/emitted/off-gassed from a variety of sources. VOC include a variety of chemicals, some of which may have short- and long-term adverse health effects. Alternate terms: odors, gases, vapors, or chemicals.
