明智地选择空气净化设备可以节约能源。空气通过空气滤清器需要动力——必须克服阻力。这种电能的年成本可以大大超过过滤系统的第一成本和维护成本。引文:研讨会，ASHRAE交易，第83卷，第一部分，伊利诺伊州芝加哥

Energy can be saved by the judicious choice of air cleaning equipment.Power is required to move air through an air cleaner - its resistance must beovercome. The annual cost of this electrical energy can greatly exceed thefirst cost of a filter system and the cost to maintain it.
