My furnace was installed with a 16x20x1 pleated filter.
It looks like there is enough space to fit a 16x20x2 filter. This
should last
longer and reduce air resistance.
Is there any reason not to?
How can doubling the thickness reduce resistance?
It doubles the surface area.

He did specify pleated. If you can find a 2" thick filter with a
single layer of media, he is correct, the surface of the media would
be approximately double that of the thinner filter, assuming the same
number of pleats and that both filters have the pleat creases at the
very outside of the filter.

Is there room in that dunce chair for two of us, dpb? It don't make no
damn sense to me, either.
