@Pravduh15 @DrEricDing Even in a home most commercial air purifiers are underpowered and/or very expensive. But either way can work, it just requires bigger/more air purifiers than people expect or buy and costs more.
@Pravduh15 @DrEricDing 即使在家中，大多数商用空气净化器的功率也不足和/或非常昂贵。但无论哪种方式都可以，它只需要比人们预期或购买的更大/更多的空气净化器，而且成本更高。
