Surely it works in parallel with whatever filter is in N1 or N2 and doesn't
waste a slot. And if you want it always on, a simple diode should do the
trick.

Steve,
I was thinking - do you think there is a way to just have the roofing
filter on all the time without having to have N1 or N2 on?
I would like to just have the roofing filter in line without waisting N1
as a switch. If I keep the N1 and N2 filtered then I always have to
have a narrow filter with the roofer.
