Pre-filter captures the majority of “larger” airborne particles after the air is blown into the machine. Thus the airflow can be powerful with less wind resistance and larger contaminants are moved away.
It can protect blowers, coils, fans, and other inner components from the congestion of impurities from the air taken in from outside. Also at the same time ensure the maximum airflow supply volume.
