PFCC's make everything run more efficient by enhancing the magnetic field induction which moves the current, especially if your home is full of appliances which use capacitors, making all of them run more efficient with this magnetic field. It will also make those PCI connections COOLER for the same reasons.
That sounds like psuedo-science garbage, and isn't backed up in any way by the link you have given.
Can you provide any support for your claims?
