General hospital area is divided into: operating room, ventilated corridor, general departments, wards, intensive wards and so on.
Operating room generally use the most efficient high efficiency filter, the choice of aluminum partitions, because aluminum can reduce bacterial growth, to prevent air pollution.
Ventilation corridor is the choice of larger air volume, efficiency, general efficient filter, because only a simple air filter, so no efficiency is too high.
General efficiency of the selection of medium and efficient sections of the filter, generally no partitions more.
Intensive wards use high efficiency and high efficiency filter, must be aluminum partitions.
