Air Cleaning Technologies – Function requirements and energy efficiency
A state-of-the-art review of various air cleaning technologies has been carried out based on scientific papers and a screening of the market for new technologies. The technologies were categorized by functionality and specificity for removal and/or destruction of specific contaminant types. It is suggested that air cleaning systems need to be based on more than one single technology in order to achieve optimal system performance. There is also a need to clear the market from inferior and even hazardous air cleaning equipment. One important step in this direction would be to include, not only traditional fibre filters, but also alternative air cleaning technologies in future standards.
