Core 400S 3-in-1 Replacement Filter
The clunking sound is most frequently caused by the HEPA filter shifting within the housing due to a lack of axial compression or mechanical deformation of the filter's plastic frame. Because the fan pulls air upward, an improperly seated or slightly undersized filter will lift under high suction and drop back down when the pressure changes, resulting in a distinct clunk. Replacing the filter ensures the structural dimensions allow the base-locking plate to properly secure the assembly against the intake gasket.
