Camfil IAQ Expert Speaks about Helping FMs Understand the Dangers of ‘Bad Air’

Cathy Hayward interviews Camfil's Peter Dyment at The Facilities Event

Camfil’s Indoor Air Quality expert, Peter Dyment in the United Kingdom, took to the stage at the Facilities Event on the 11th April, to explain how FMs can combat poor IAQ in their buildings; focusing on the dangers of the smallest particulate matter - PM1 and below.

With the majority of our workplaces in polluted city centres, ensuring the inside of these buildings are safe havens is essential – particularly as many of us spend around 90% of our lives indoors. Dyment explained the potential risks posed primarily from traffic fumes, including NOx, SOx and particulate matter. In locations with high concentrations of these elements opening a window is not a safe way to ventilate a building.

He also made the point that pollutants don’t just come from the outside in. Carpets, paints, cleaning fluids, photo copiers and even people release damaging substances into the air, including Volatile Organic Compounds (VOCs) and Aldehydes.

Invisible dangers

The problem is that we can’t see these dangers – in the past pollution was visible, with large particulates viewed as a smog. Nowadays the majority of pollution is invisible, meaning it poses more of a risk as the main composition is the smallest of particles. Unstoppable by our bodies natural defences, PM1 and below can get inside our blood stream, respiratory and nervous systems. These particles can even get into our brains and have been linked to Alzheimer’s.

In highly polluted areas we inhale 25 million particles with each breathe, not to mention combustion gases such as NOx.

Make buildings safe

Making our buildings safe, however, is easier than ever before thanks to high grade levels of HEPA and molecular filtration which stop PM1, and more effective, user friendly standards, designed to help specifiers and FMS choose the best solutions for their particular application.

By using all of the available standards and guidelines…

  • BS CEN 16798-3 - IAQ filter requirements
  • BS CEN ISO16890 - Particle filter testing
  • BS CEN ISO 10121-2 - Molecular filter testing
  • Eurovent - supply filter requirements
  • World Health Organisation (WHO) guidelines on air pollution exposure limits

The right air filtration scheme can be chosen – of particular importance in highly populated buildings, such as large offices, schools and hospitals.

Camfil offers a range of solutions, from concealed fan cylinder units housed inside Air Handling Units to standalone ‘plug and play’ air purification systems suitable for use in our homes.

The good news is that indoor air can be fixed. We need to take the risks posed by poor IAQ seriously and do everything it takes to keep occupants safe.

Taking place from the 9th-11th April at the NEC in Birmingham, The Facilities Event exhibition and seminar conference is a key meeting place for the UK’s FM and workplace industry.
