Camfil has welcomed recognition of the effect of Indoor Air Quality (IAQ) on health in the government's Clean Air Strategy launched this week.
The document outlines a range of recommendations that focus on reducing exposure to particulate matter (PM), the very smallest of which cause the most damage.
Simon Birkett, from Clean Air London (CAL), who works with Camfil to improve air quality in the capital, said: "It is marvellous to find more than 20 mentions of indoor air quality in Defra's new Clean Air Strategy. The strategy helpfully identifies the sources of many different indoor air pollutants and says that plans will be forthcoming to reduce them.
"The Clean Air Strategy makes an encouraging start on indoor air quality but must be followed through quickly with meaningful action. For example, Building Bulletin 101 (BB101), which sought to improve indoor air quality in schools, was published with out of date standards for air filtration. Producing corrected guidance in 2019 must be a priority.
"Within healthcare, the ‘Change in Air Filter Test and Classification standards', issued by SVHSoc in November 2018, is an important step but CAL considers that ‘HTM 03-01; Specialised Ventilation for Healthcare Premises; Part A' needs also to be updated for the latest ISO and British standards for air filtration."
Mark Taylor added: "With air filtration a key step in improving IAQ, another important standard that will help contribute to improvements in this area is the Eurovent Energy Rating 2019, which came into force on January 1. Under the new Eurovent classification, the demands on energy efficiencies have increased improving the performance of their filters through more stringent test standards."
