The indoor air quality meter measures in real time:

formaldehyde (HCHO) - a highly toxic cancer-causing chemical that can be found in furniture, textiles, building materials, cleaning products...

volatile organic compounds (TVOC) - gaseous substances that come from: varnishes, paints, furniture, cleaning products, acetone, toluene, benzene...

fine particles (PM2.5 and PM10) - solid or liquid particles in the air - dust, soot, aerosols, candles and other combustion processes

carbon monoxide (CO) - faulty gas stoves, boilers, fireplaces, solid fuel stoves, cookers. Also petrol engines. Poor ventilation also produces more CO.

Carbon dioxide (CO2) - rises rapidly in a room when there is poor ventilation or a large crowd. High CO2 levels cause decreased concentration and fatigue.
