How do I measure air quality at home or in the office?

Indoor air quality levels can be assessed and monitored by looking at parameters such as CO2 (carbon dioxide) and VOC (volatile organic compounds).

Indoor air quality in the home and workplace is an important requirement for individual comfort and health. One of the parameters conventionally used to measure air quality in confined spaces is the concentration of carbon dioxide (CO2) produced by respiration: this parameter, measured in ppm (parts per million), is used as a marker of pollution caused by occupancy. Comparing the CO2 concentration measured inside the building with the external rate (generally around 400 ppm) can give an idea of the occupancy of spaces. Another parameter that is often taken into account are VOCs, volatile organic compounds that can be introduced into the indoor air by furnishings, coatings, building materials, printer toners and photocopiers. These IAQ (indoor air quality) parameters can be detected with specific instruments, available both to professionals and to consumers. The Helty Flow top-of-the-range models, including the Elite or Pure version of the Flow 40,70 and 100 models, feature sensors that monitor humidity, CO2 and VOC (the values can be consulted at any time through the Air Guard app).
