ASHRAE标准145.1提供了一种标准实验室试验方法，用于评估气相空气净化系统中使用的松散颗粒介质的性能。这些试验的结果可以为空气净化设备的设计和选择以及控制室内气体污染物浓度的空气净化系统的设计提供有用的信息。

ASHRAE Standard 145.1 provides a standard laboratory test method for assessing the performance of loose granular media used in gas-phase air-cleaning systems. The results of these tests can provide information that is useful in the design and selection of air-cleaning equipment and the design of air-cleaning systems for controlling indoor concentrations of gaseous air contaminants.
