Particulate Matter are tiny fragments of matter suspended in the air, often invisible to the naked eye, but which can have harmful effects on human health. In the workplace, the presence of PM can come from a variety of sources, and their impact on employees and energy comfort can be significant. In this article, we explore the origin of PM, its effects on individuals and the working environment, and the importance of measuring and controlling it using Nexelec’s indoor air quality sensors.

Understanding and controlling Particulate Matter in the workplace

In this article:

Origin of particulate matter (PM) in workspaces

PM in workspaces can come from a variety of sources, including:

  1. Combustion: Emissions from vehicles, heating, ventilation and air-conditioning (HVAC) systems and cooking appliances can produce PM resulting from the incomplete combustion of fossil fuels or biomass.
  2. Human activities: Activities such as printing, photocopying, sanding and painting can release PM into the air through the handling of chemicals and materials.
  3. Furniture and building materials: Some building materials, floor coverings, furniture and cleaning products can release PM, especially volatile organic compounds (VOCs), which contribute to indoor air pollution.

Impact of particulate matter on employees

The presence of particulate matter in workspace air can have several adverse effects on the health and well-being of employees, including :

  1. Respiratory irritation: PM can irritate the respiratory tract, causing symptoms such as coughing, sore throat and watery eyes.
  2. Health problems: Prolonged exposure to fine particles can aggravate the symptoms of people suffering from respiratory illnesses such as asthma and bronchitis, and increase the risk of developing cardiovascular disease.
  3. Decreased productivity: The health effects caused by particulate matter can lead to lower employee productivity, through absenteeism, sick leave and reduced concentration at work.

Energy comfort and indoor air quality

In addition to impacts on individual health, the presence of particulate matter can also affect energy comfort and overall indoor air quality in workspaces. High levels of fine particles can contribute to a stuffy, unpleasant atmosphere, which can compromise the general well-being of building occupants.

Measure and control particulate matter with Nexelec indoor air quality sensors

To ensure a healthy and comfortable working environment, it is essential to monitor and control levels of PM in indoor air. Nexelec’s indoor air quality sensors offer an effective solution for accurately measuring the concentration of PM and taking corrective action where necessary.

Thanks to their advanced technology, Nexelec’s indoor air quality sensors can detect PM levels in real time, providing valuable data on air quality in workspaces. By integrating these sensors into building management systems, companies can actively monitor indoor air quality. They can also identify sources of pollution and implement corrective measures to improve the health and well-being of their employees.


The presence of fine particles in workspaces can have adverse effects on employee health, energy comfort and indoor air quality. By understanding the origins and impacts of PM, and using cutting-edge technologies such as Nexelec’s indoor air quality sensors, companies can create healthier, safer and more comfortable working environments for their employees, promoting productivity and overall well-being.
