Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...
Air fresheners, cleaning products, paints, printing, flooring, and wax and polish products can also be a source of volatile organic compounds (VOCs) and semi-volatile compound (SVOCs). The LEED v4 Handbook posits that indoor air quality is "one of the most pivotal factors in maintaining building occupants' safety, productivity, and well-being ...
The European Environment Agency collects its air quality data from 3,500 monitoring stations across the continent. [24] The measurements made by sensors like these, which are much more accurate, are also near real-time and are used to generate air quality indexes (AQIs). Between the two extremes of large-scale static and small-scale wearable ...

Diffusion tubes are widely used by local authorities for monitoring air quality in urban areas, [2] in citizen science pollution-monitoring projects carried out by community groups and schools, [3] [4] and in indoor environments such as mines [5] and museums. [6]
Passive or "diffusive" air sampling depends on meteorological conditions such as wind to diffuse air pollutants to a sorbent medium. Passive samplers, such as diffusion tubes, have the advantage of typically being small, quiet, and easy to deploy, and they are particularly useful in air quality studies that determine key areas for future continuous monitoring.
It also generally requires periodic or continuous monitoring of air quality. As an example, the United States Environmental Protection Agency has developed the National Ambient Air Quality Standards (NAAQS) [ 6 ] NAAQS set attainment thresholds for sulfur dioxide , particulate matter (PM 10 and PM 2.5 ), carbon monoxide , ozone , nitrogen ...
Ventilating or ventilation (the "V" in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and ...
