In-cabin air quality: electrostatic field to capture sub-micron size particles
University of Borås, School of Engineering.
2014 (English)Conference paper, (Refereed)
Abstract [en]

Traffic is regarded as the main reason for the air pollution problem and it seems obvious to try to reduce the particulate bioload affecting those travelling. Recently Volvo Cars introduced their Interior Air Quality System forcing the cabin air to be recirculated in case of a high level of noxious gases shutting out carbon monoxide, ground-level ozone and nitrogen dioxide. Ionization is another component of Mercedes AIR-BALANCE package. Considering the fact that it is the nano-size ultra-fine particles (UFP) that are known to cause the “oxidative” stress of the immune system one may ask if even the most well designed HEPA filter would sufficiently affect the in-cabin air particulates or is there a need for additional means by which the sub-micron class particles may be captured. An electrostatic field of sufficient strength may serve as an additional tool to clean the cabin air from sub-micron size particles.The initial data from the study indicate that electrostatic mechanisms substantially add to the in-cabin air cleaning properties of ultra-fine particulates compared to the standard filtering technology when recirculating the cabin air.
