为了实施于百叶窗 8形成过滤水帘 20， 百叶窗 8设有多个叶片 29， 每个叶片 29之间留有间隙，过滤水帘 20由百叶窗 8上部的第一个叶片 30 流向最后一个叶片 31， 每个叶片 29之间形成一个间隙水帘 32， 过滤水帘 20由多个间隙水帘 32构成， 每个间隙水帘 32位于相邻的叶片 29之间。
为了使过滤水 19具有消毒的作用，水箱 1 1连接有消毒液注入装置 33， 消毒液注入装置 33包括有注入漏斗 34以及管道 35， 注入漏斗 34与管道 35连通， 管道 35与水箱 11连通， 漏斗 34位于出风口 10旁边， 用于将消 毒液导入水箱 11， 使过滤水 19具有消毒以及杀菌的功能。 为了实施双向排气扇 37排气以及抽气的功能， 风叶 5为双向轴流风 叶， 由外壳 2以及外壳 2的进风口 9以及出风口 10构成一个轴流风道， 电机 4正转时，风的流动方向为由进风口 9流向出风口 10，电机 4反转时， 风的流动方向为由出风口 10流向进风口 9。
为了加强过滤水帘 20的过滤效果， 百叶窗 8为阶梯式百叶窗， 百叶 窗 8的每个叶片 29与相邻上方的叶片 29构成一个阶梯， 每个叶片 29到 出风口 10的距离大于相邻上方一个叶片 29到出风口 10的距离； 每个叶 片 29与相邻上方的叶片 29形成一个间隙水帘 32， 每个间隙水帘 32到出 风口 10的距离大于相邻上方间隙水帘 32到出风口 10的距离， 多个间隙 水帘 32构成阶梯式的过滤水帘 20， 使新鲜空气可以通过过滤水帘 20， 同 时也使过滤水帘 20不易被风吹散， 保持其过滤效果。
PM2. 5换气扇装置的工作原理是： 使用时， 将 PM2. 5换气扇装置安装 于房间的墙壁上， 并使外壳 2的出风口 10位于室内一侧， 进风口 9位于 室外一侧，利用控制器 3控制其过滤装置 1直接把室内的空气排出到室内， 然后， 将室外的新鲜空气通过其过滤装置 1过滤后引入室内， 如此不断循 环； 由室外引入新鲜空气时， 控制器 3控制电机 4正转， 电机 4带动风叶 5以及水泵 6正转， 水箱 11的过滤水 19被水泵 6抽至水帘喷头 7， 由水 帘喷头 7喷到百叶窗 8， 过滤水 19由百叶窗 8的上部流向下部， 过滤水 19在百叶窗 8形成一个过滤水帘 20; 同时， 风叶 5正转， 将室外的新鲜 空气由进风口 9抽入， 新鲜空气经过百叶窗 8的过滤水帘 20过滤后由出 风口 10进入室内， 利用过滤水帘 20吸收新鲜空气中的灰尘以及 PM2. 5; 将室内的空气排出室内时， 控制器 3控制电机 4反转， 单向传动联轴器 15 反转不起传动作用， 水泵 6不转动， 电机 4只带动风叶 5反转， 室内的空 气由出风口 10进入， 室内空气由百叶窗 8经进风口 9排到室外。
为了实施于进风口 9的百叶窗 8形成过滤水帘 20， 利用过滤水帘 20 吸收空气的灰尘以及 PM2. 5，水帘喷头 7喷出的过滤水帘 20的流向为由百 叶窗 8的上部流向百叶窗 8的下部， 再由百叶窗 8的下部流入水箱 11 ; 室 外的新鲜空气由进风口 9抽入， 经过百叶窗 8的叶片 29与叶片 29之间的 间隙水帘 32过滤后， 进入室内。
为了控制电机 4正转以及反转的时间， 控制器 3设有时间继电器， 控 制电机 4正转以及反转的时间， 电机 4正转的时间与反转的时间的比例为 4 : 1。
为了控制水箱 11的水位， 水箱 11的水位低于水位开关 26的位置时， 水位开关 26将其信号传输给控制器 3，控制器 3控制进水电磁阔 25打开， 自来水进入水箱 11 ; 水箱 11的水位高于水位开关 26的位置时， 水位开关 26将信号传输给制器 3， 控制器 3控制进水电磁阔 25关闭， 进水停止。
