一般FFU系统由于单位风量的能耗较大，因此洁净室的冷负荷亦相应增加。2具体情况下的评价FFU用于老建筑物改造成洁净室时，其综合经济性一般往往可取。洁净度要求严的洁净室，末级过滤器满布率1%时，对大的系统采用FFU，当前还是不经济的;对小系统有意义作具体比较。对洁净度要求不甚严的洁净室，末级过滤器满布率4%时对大系统综合经济性往往相差不多，但对IC工厂而言FFU系统的灵活性是重要的，因此当前IC工厂对过滤器满布率4%时，采用FFU系统已经普遍。
早期在布袋除尘器失败后，燃煤锅炉烟气除尘基本应用电除尘器。但随着环保要求的日益提高、电除尘器的广泛运用，其弱点也逐渐暴露出来。首先，静电除尘器的除尘效率不稳定。电除尘器运行初期，除尘效果基本能达到要求，但由于其结构及工作原理的局限，随着运行时间的延续，电除尘器内部组件变形、积灰、电场变化，除尘效果不断下降，烟尘排放超标。其次，电除尘器的运行综合费用高。电除尘器在运行一个周期后，内部结构变形、损坏比较严重，为保证其正常运行，电厂不得不经常对电除尘器进行维修。
