The filtration level of dust filter cartridges is usually divided according to their filtration efficiency and particle size. The following are several common filtration levels and their applicable scenarios:
Primary filter (G1-G4):
mainly intercepts large particle pollutants larger than 5 microns, such as dust, hair, fiber, etc. The filtration efficiency ranges from 20% to 90%. Suitable for primary filtration of ventilation systems such as office buildings, shopping malls, and public places to protect subsequent equipment
Medium efficiency filter (F5-F9):
mainly filters medium-sized particles of 1-5 microns, such as pollen, smoke, bacteria, etc. The filtration efficiency ranges from 45% to 95%. Suitable for places with high air quality requirements such as hospitals, schools, and industrial plants
High efficiency filter (HEPA, H10-H14):
for tiny particles below 0.3 microns, such as viruses, PM2.5, aerosols, etc., the filtration efficiency is as high as 95%-99.999%. Suitable for environments with extremely high air quality requirements, such as hospital operating rooms, electronic clean rooms, etc.
