Few studies have evaluated the performance of air purifiers in removing airborne fungi houses. Here, we ability a HEPA purifier fan to remove six houses Japan. In each house, number decreased more rapidly when was on (test measurement) than it off (control) , demonstrating its decrease fungal concentration. The between 1.5 and 6 times faster (spontaneous decrease) . Clean change rates, calculated from measurements taken 15 min after test equipment operation began, ranged 2.9 5.4 (h-1) indicating adequate cleaning. One contained much greater concentration standard set by Architectural Institute When operated indoor/outdoor (I/O) ratio 77.5, equating 53,000 cfu/m3 at 0 0.72 or 620 45 min, which is below standard. This reduction clearly demonstrated antifungal effect fan.
