@sri_srikrishna @CleanAirStars @ocnj3 Sorry, that was extremely unclear. What I meant is that concentration reached depends on the volume (rate) of air exchange. With 1 ACH, a space with twice the volume will have half the concentration.
@sri_srikrishna @CleanAirStars @ocnj3 抱歉，这非常不清楚。我的意思是达到的浓度取决于空气交换的体积（速率）。使用 1 ACH，两倍体积的空间将有一半的浓度。
