Variable-speed everything but it’s simply loaded with filtering components.


HI Gary, NA6O

I am faced with having to replace my furnace.   Thanks for sharing 
details below as I was pondering about this myself too.

Are the filtering components included in Variable Speed controller you 
mention by default or did you have to procure and install filter 
separately as an proactive measure to combat RFI ?
