I explained that!

Putting mfd range caps across the AC line will shift power factor. Unless you have a power factor problem and need to do that it serves no purpose. And determining if you have a power factor problem is way beyond the general knowledge on this forum. In a residence you don't worry about power factor.

Power factor is the lead/lag of the current vs voltage. That's right, current out of phase with the voltage! Wrap your mind around that idea.

Thinking that a mfd range cap does a better job filtering out RFI than a mmfd cap is just novice logic. If you have a bad RFI problem then you need a Pi filter.
