Airflow on high speed with all filters clean and no ducting is about 400 CFM. The unit can be run with very dirty filters and virtually no flow without harming the unit. The operator’s decision to change filters should be based on filter cost vs. the unit’s filtering effectiveness. If airflow is 200 CFM vs. 400 CFM, the unit will filter particles from a space at half the rate. The operator must judge if that is acceptable.

If the operator determines the filters should be changed due to low airflow, it is most economical to change them in the following order:

Change the pad pre-filter (top) first. This is the least expensive filter. Recheck the airflow. If the airflow is acceptable, no other filters need to be changed.

Change the pleated fabric filter (middle) second. It is the second least expensive filter. Recheck the airflow.

If acceptable, the HEPA filter does not need changing.

If the airflow is still too low, the HEPA filter must be changed. To remove the HEPA filter, follow these steps:

1.Loosen the two 3/8” thumbscrews that secure the HEPA filter.

2.Push down on the filter hold-down bar and out on the back of the cabinet to disengage the two “ears” from the back of the cabinet. Rock the filter hold-down bar up towards the front of the cabinet.

3.Disengage the screw and spacer from the hole in the front of the cabinet and remove the filter hold- down bar.

4.Lift the old filter straight up and out of the cabinet. Place the new HEPA filter with the open side down, into the cabinet. Be sure the four bumpers on the base center it.
