British ventilation manufacturer Vent-Axia is supporting Clean Air Day today (Thursday, 19 June 2025). This year’s campaign highlights how air pollution affects us from before our first breath until our last, and encourages people to understand the health risks as well as urge MPs to support stronger air quality laws in the UK so we can all breathe cleaner air and live healthier lives. Clean Air Day is the UK’s largest air pollution campaign, led by Global Action Plan, a UK environmental charity, with the support of Health Equals. The campaign aims to raise public understanding of the harmful effects of air pollution, inspiring the public to take action to clean up the air.
Awareness of the importance of good indoor air quality (IAQ) has grown significantly since the pandemic, but concern has deepened in recent years following the death of 2-year-old Awaab Ishak, caused by a mouldy home. As a result, from October, Awaab’s Law, part of the Social Housing (Regulation) Act, is set to impose strict legal requirements on social landlords to investigate and resolve mould issues. Consequently, households are becoming more aware of the risks associated with poor IAQ and condensation and mould.
But IAQ issues affect more than just social homes. Research from the University of Birmingham recently found that people may be exposed to unhealthy levels of airborne pollutants inside their homes, even if outdoor air quality is good. The research found significant differences in particulate matter (PM) levels between three houses that were studied over a two-week period, with one home exceeding the World Health Organisation (WHO) 24-hour PM2.5 limit on nine days. Factors that influenced particle levels in the study included household location, ventilation, and occupancy, illustrating the complexity of indoor air quality.
As well as PM2.5, indoor air can contain over 900 chemicals, particulates, biological materials, viruses, and bacteria. Each of us breathes 9,000 litres of air a day, so poor IAQ can affect the health of everyone in the home. Even naturally occurring CO2 can have an impact on our health, with high levels of 2,000-5,000 PPM causing headaches, sleepiness, poor concentration, increased heart rate, and slight nausea.
“At Vent-Axia, we are committed to tackling indoor air pollution and helping people create healthier homes; we are therefore supporting Clean Air Day since we know how air pollution affects us from before our first breath until our last,” says Katie Mairs, Channel Marketing Manager at Vent-Axia. “This Clean Air Day we are therefore encouraging households to take three main actions: Reduce the number of pollutants introduced into the air, dilute the pollutants in the air by ensuring there is adequate ventilation introducing fresh clean air, and purify by adding an air purifier to remove the remaining pollutants from the air.”
It is vital to combat air pollution to protect health and wellbeing. By making some simple changes, households can protect themselves and others by ventilating and purifying their home to improve the air they breathe.
