Vehicle Interior Air Quality (VIAQ)
People spend approximately an hour per day in vehicles. Many studies, historical and current, are addressing outdoor air pollution that arises from traffic, and its associated negative impacts on public health, but little is known about indoor air quality in vehicles. Despite the relatively short period of time spent in cars, exposure levels are of concern given the immediate proximity to motor vehicles plus, in urban areas, high ambient concentrations compared to other micro-environments. With new advances coming in the automotive industry concerning HVAC and control strategies for improving the air quality inside the vehicle, this topic is anticipated to grow.
Introducing ‘PIMS’
NAQTS and our partner Emissions Analytics have developed the measurement technology and techniques to analyse real-time VIAQ. Through taking measurements using two NAQTS PIMS units —one placed inside the vehicle, the other outside it— we can measure the relationship between the ambient air quality and the air quality inside the vehicle.
Types of Testing
Benchmarking – vehicles and cabin air quality technologies
Intervention – before and after testing, for example comparison of filtration technologies
Location – effects of different environments to VIAQ. For example, the difference between urban and rural
