This study was performed\n                    to evaluate contributions of air cleaner to air pollutants and pig productivity\n                    under on-site situation of commercial pig building. Air pollutants concentration\n                    and pig\u2019s productivity index between the control room and the treatment\n                    room has been monitored for six months according to pig\u2019s rearing stage:\n                    0 day (farrowing), 21st day (farrowing\u2013weaning), 70th day\n                    (weaning\u2013nursery), 140th day (nursery\u2013growing) and 180th day\n                    (growing\u2013fattening). Generally mean concentrations of air pollutants\n                    derived from pig building were relatively higher in the control room than in the\n                    treatment room. The reduction efficiencies of air cleaner for air pollutants\n                    were 5%\u201310% for 0 day, 10%\u201320% for 21st day, 15%\u201325% for\n                    70th day, 20%\u201335% for 140th day and 30%\u201345% for 180th day,\n                    respectively. Furthermore, application of air cleaner had a positive effect on\n                    pig\u2019s body weight gain, feed conversion, pig activity index and mortality\n                    rate through all the pig\u2019s rearing steps. The pig\u2019s body weight\n                    gain and pig activity index showed significant correlations with total suspended\n                    particle (TSP) and particulate matter (PM)2.5, and
