Indoor Air Quality

Indoor Air Quality

Indoor Air Quality (IAQ) has been the focus of attention over the past few years. The diesel emissions scandal has put a spotlight on NOx and diesel particulates. Even woodburning stoves have been scrutinised as they have grown in popularity in urban environments.

These emissions are generated outside of the building, but these and others are finding their way into the built environment through the fresh air supply. They affect buildings close to busy road networks, fuelling a growing need for solutions that can remove these harmful airborne contaminants. As well as incoming air pollutants, other elements such as carbon dioxide, temperature and humidity vary in a building. Alongside Volatile Organic Compounds (VOCs) which leach from furniture and fittings and the spread of viruses and mould spores through the HVAC systems (Heating, Ventilation & Air-Conditioning), they result in 2-5x more pollution indoors than outdoors.

We spend a huge 90% of our time indoors and consume on average 10,800L of air each day. So, at the very least, it would seem sensible to ensure that indoor pollutants are kept in abeyance. But where can we start?

HVAC systems are essential for managing the air in offices, shops, malls and factories. They are the lungs of the building, ensuring a supply of fresh air and managing temperature and carbon-dioxide levels. However, according to the Global Environment Protection Agency, HVAC systems are the number one cause of microbial contaminants and bad IAQ. This conflict presents a significant challenge, but there are solutions.


In response to increasing customer demand, Plasma Clean now delivers a growing portfolio of products and services to dramatically improve indoor as well as outdoor air quality such as:

  • Low-pressure-drop air filters to remove harmful contaminants from incoming air 
  • UVC light systems to treat heat-exchange coils (inherent in HVAC systems), removing the need to manually clean them
  • Air-quality sensors to continually monitor and feed back into the Building Management System (BMS
