过滤器沾水后过滤效率不稳定，使用寿命会缩短，所以大风量过滤器应避开加湿器和表冷器等设备的近距离安装，并建议在这些设备后安装挡水板。
If stained with water, air filters would have shorter operation time with unstable efficiency; therefore Coflair™ filters should not to be installed near to humidifier and heat exchanger behind which board to keep off the water should be installed.
为延长大风量过滤器的使用寿命，在前段加装过滤等级不低于 F7 的预过滤器，以降低大风量过滤器上游气流的含尘浓度。
To extend lifetime of Coflair™ air filter, pre-filters classified not lower than F7 should be used to reduce dust density of upstream air.
