Optional air filter principle: According to the requirements of clean-room standards, to determine the final stage of the air filter efficiency
Indoor requirements in general, you can choose the early effect filter; if the room requires moderate purification efficiency and should be used early in effect two filters; if the room clean purification requirements, you can use at the beginning, middle and high efficiency three purification filtration and to reasonable levels of efficiency of the filter to match the adjacent filter efficiency levels should not differ too much.
