Primary layer of filtration that collects large particles before they reach the second stage filter and HEPA filter. Removes large particles up to 10 microns
and larger from the air flowing through the unit, thereby preventing premature loading of the second stage and HEPA filters. The pre-filter pad is recommended to be
changed as it becomes loaded and the airflow capacity of the unit decreases—or the pressure gauge at the control panel exceeds 2.6 inches at high speed or 1.9 inches at low
speed, of W.C.
