Can anyone recommend an electrostatic cleaning unit for a forced air
Also I'd like to get one with UV treatment/ionization as well, is
there such a thing?
The original installer did leave a "box with cover" installed where
the cold return enters the air handler, I'm assuming this box is for a
future electrostatic filter installation. Are these boxes a standard
size? Or am I locked into getting a specific electrostatic unit. I
use 16x25 filters so the box is probably 16x25x8 inches and looks like
it will accept some kind of slide-in electrostatic unit.
