A portable fume hood design with an acid pollution absorber filter was prepared. This study aims to: (1) make a portable fume hood equipped with an acid contaminant absorbent filter housing, and (2) determine the length of time the ability of the lime granule can function as an acid contaminant absorbent filter. This study is a quasi-experimental study using posttest only with control group design to assess the feasibility of using lime granules as acid absorbent filters on portable fume hoods. Data analysis was performed by regression using the Excel program. The results of the study are as follows: (1) portable fume hood that use acid-absorbent filters have been made, (2) The average length of time the ability of lime granules can function as an acid contaminant absorbent filter on the use of a portable fume hood at a lime granule weight of 0.5; 1,0; 1,5; and 2.0, respectively 222, 589, 880, and 1219 minutes. This relationship can be estimated with a regression equation Y = 0.619X -36.71. Which Y is the ability of lime granule as absorbent of acid contamination, and X is the weight of lime granule.

准备了带有酸污染吸收过滤器的便携式通风柜设计。本研究旨在：(1) 制造配备酸性污染物吸收过滤器外壳的便携式通风柜，以及 (2) 确定石灰颗粒作为酸性污染物吸收过滤器的能力的时间长度。本研究是一项准实验研究，仅使用后测和对照组设计来评估使用石灰颗粒作为便携式通风柜上的酸吸收过滤器的可行性。使用Excel程序通过回归进行数据分析。研究结果如下：（1）已制成使用酸吸收过滤器的便携式通风柜，（2）石灰颗粒作为酸污染物吸收过滤器的平均使用时间。石灰颗粒重量为 0.5 的便携式通风柜；1,0; 1,5; 和 2.0，分别为 222、589、880 和 1219 分钟。这种关系可以用回归方程 Y = 0.619X -36.71 来估计。其中Y是石灰颗粒作为酸污染吸收剂的能力，X是石灰颗粒的重量。
