Fig. 4From: Effect of forceful suction and air disinfection machines on aerosol removalCorrelations between air disinfection machines (ACHdm) or forceful suction (ACHfs) and times needed to 95% or 100% removals of the 0.3 μm aerosol aerosol particles. Higher ACHdm(A, B) and ACHfs(C,D) are highly correlated with shorter times needed to reach 95% or 100% aerosol removalBack to article page
