Effectiveness of the real-time air disinfection device against Staphylococcus albus in the air.

Time (min)	No.	(Cfu/m^3)	(Cfu/m^3)	Nt (%)	(Cfu/m^3)	(Cfu/m^3)	Kt (%)
30	1		1.76 × 10^5	33.33	2.64 × 10^5	160	99.91
	2		1.51 × 10^5	38.11	2.52 × 10^5	150	99.90
	3		1.40 × 10^5	39.39	2.40 × 10^5	130	99.91

N_t: the natural extinction rate of bacteria in the air; and : the amount of bacteria in the air at different times before and during the experiment was conducted; and : the amount of bacteria in the air at different times before and during the disinfection process of the experimental group; K_t: the disinfection rate of bacteria in air.
