Vent-Axia welcomeslatest air quality research

British ventilation manufacturer Vent-Axiahas welcomed the latest research from the Royal College of Physicians (RCP) on air quality and its impact on public health.


report, published in collaboration with Lancet Countdown, has found that 44 UK cities are in breach of recommended World Health Organisation (WHO) guidelines for fine

particulate matter (PM2.5). Vent-Axia is committed to improving public health and recently launched its award-winning Vent-Axia Pure Air advanced air filtration system, which helps address indoor air quality (IAQ) issues. In 2016, the RCP and the Royal College of Paediatrics and Child Health

estimated that ambient air pollution causes approximately 40,000 premature deaths, over 6 million sick days and an estimated total social cost of £22.6 billion per year in the UK. It is clear that there is a very real need for national action in tackling air quality.

Exposure The RCP’s lead on sustainability, Dr Toby Hillman, said: “We know that high exposures in early life have a major effect on lung and cognitive development throughout an individual's life – that is why it is the government's duty to improve the air we breathe and to ensure that people across the UK are not exposed to such a preventable cause of death and illness.” To this end, the government published its National Air Quality Plan in July with local authorities in England being required to draw up plans to improve air quality. This has been followed up with the Autumn Budget announcement of reforms to improve air quality in the UK, including a new Clean Air Fund. This £220m fund, financed by targeted changes to company car tax and

to vehicle excise duty for those buying new diesel cars, will support English local authorities to support people and businesses to adapt as measures to improve air quality are implemented. “This latest RCP report addresses the crucial issue of the state of air

quality in the UK. With air pollution reaching crisis point, IAQ is becoming an increasing concern,” explains Ian Mitchell, Product Marketing Manager – New Build Residential, Vent-Axia.

Causes “Whilst the government is starting to address the causes of air pollution, until air quality improves it is essential to look at ways of improving the quality of air being brought into our homes. One such solution is our innovative Vent-Axia Pure Air filtration system.”

The WHO’s recommended limit for

particulate matter smaller than 2.5 microns (PM2.5) is 10μg/m3 and the 44 UK cities mentioned in the report all exceed this, whilst 13 exceed the PM10 limit (20μg/m3). PM2.5 refers to atmospheric particulate matter (PM) with a diameter less than 2.5 micrometers and it is among the air pollutants which has the greatest impact on human health including respiratory and cardiovascular diseases. The RCP report calls for a

“comprehensive policy package” to reduce air pollution across the UK, including mandatory clean air zones in cities across the country. It also highlights the need for new policies to ensure

that the Fourth and Fifth Carbon Budgets are met, and to further drive down

the carbon intensity of electricity generation. Plus it recommends increased investment in active transport to raise levels of walking, cycling and public transport use nation- wide, as well as comprehensive and joined-up climate adaptation

policies. The adoption of these recommendations could only impact positively on the nation’s health.

Pollutants Vent-Axia has set the benchmark for high-level filtration with its Vent-Axia Pure Air filtration system, designed to be used in conjunction with Mechanical Ventilation with Heat Recovery (MVHR) and Demand Energy Recovery (D-ERV) systems. MVHR and D-ERV systems extract harmful pollutants and filter the air coming into a building, taking out airborne bacteria and dangerous contaminants. The Pure Air filter then goes one step further to improve IAQ. It is fitted

to the intake airflow and incorporates two types of filtration—activated carbon and G4/F7 particulate filters to achieve even higher levels of filtration. G4 filters can remove up to 90% of the PM10 particles in the air, including some bacteria, most pollens and many types of industrial dust. Meanwhile, the finer F7 filters are ideal for inner city areas with heavy traffic since they remove up to 80% of the tiny PM2.5 particles, this includes fine diesel particulates. By removing these pollutants from the outside air being brought into a building, Pure Air improves IAQ and so offers a healthier indoor environment. Whilst the government is starting to address the causes of air pollution,

until air quality improves it is essential to look at ways of improving the quality of air being brought into our homes.
