For environments with elevated levels of coarse dust, the PF40 kit can be added to any IQAir air purifier system for superior coarse dust filtration. This helps to extend the life of the unit's standard pre-filter element.
The PF40 kit consists of an upper grille which screws into the air purifier's base. A synthetic coarse dust filter pad is held in place by a lower grille that is secured by four clips. The 1/2 inch deep non-woven design of the PF40 filter pad ensures superior coarse dust holding capacity.
The filter pad may be washed several times before it needs to be replaced. 3 replacement pads included.
Compatible with all IQAir air purifier devices. Not compatible with the accessories FlexVac, VM FlexVac, VM InFlow and InFlow W125.
