IQAir PF40 Coarse Dust Pre-Filtration Kit for Areas with High Levels of Dust

If coarse dust is a problem . the IQAir PF40™ Kit can be added to almost any IQAir system. It allows the air purifier's standard pre-filter to be more effective by trapping additional coarse dust in environments with elevated levels of larger particles. This makes the PF40™ Kit a perfect solution for desert locations and other environments with high levels of dust . and also commercial applications such as bakeries or spaces affected by feather dust from birds . etc. Total filter life remains the same for all filters even with the addition of the PF40™ Kit. The PF40 kit consists of an upper grille which screws into the filtration device'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.
