Wiley Online: The impact of particle filtration on indoor air quality in a classroom near a highway

Abstract A pilot study was performed to investigate whether the application of a new mechanical ventilation system with a fine F8 (MERV14) filter could improve indoor air quality in a high school near the Amsterdam ring road. PM10, PM2.5, and black carbon (BC) concentrations were measured continuously inside an occupied intervention classroom and outside the school during three sampling periods in the winter of 2013/2014. Initially, 3 weeks of baseline measurements were performed, with the existing ventilation system and normal ventilation habits. Next, an intervention study was performed. A new ventilation system was installed in the classroom, and measurements were performed during 8 school weeks, in alternating 2-week periods with and without the filter in the ventilation system under otherwise identical ventilation conditions. Indoor/outdoor ratios measured during the weeks with filter were
compared with those measured without filter to evaluate the ability of the F8 filter to improve indoor air quality. During teaching hours, the filter reduced BC exposure by, on average, 36%. For PM10 and PM2.5, a reduction of 34% and 30% was found, respectively. This implies that application of a fine filter can reduce the exposure of schoolchildren to traffic exhaust at hot spot locations by
about one-third.

“COVID-19 vaccination is safe during pregnancy and may protect newborns from infection, especially if vaccines are given in the second or third trimester. This is similar to what we are already doing with other maternal vaccines, including TDaP and seasonal influenza.” – Dr. Eastabrook
“If we had an epidemic of people with broken limbs and we saw people in plasters and crutches, it would be more evident. But there is a lot of disability that is happening, which is a hidden disability often, which is why we need to talk about it more, for people to understand what the consequences are. And that will help to make better decisions.” - Lynette
