Impianti di climatizzazione, come scegliere i sistemi filtranti

Air filtration is a very technical subject. EN 13779 standard aims to help making conscious choices for air filters to be installed in HVAC systems. The lack of knowledge about the in situ performance of air filters has not so far allowed to prepare a methodology based on sound and reliable data. Much work still needs to be done to provide end users and HVAC designers with a meaningful and useful classification system. In this sense, the active participation of end users and HVAC designers to the standardization work in the field of air cleaning technologies would contribute to address the problem of the actual performance of air filters serving HVAC systems.
