The company that installed my HVAC system a few years ago used a filter =
box on the return line that takes 20=E2=80=9D x 25" x 4=E2=80=9D =
filters, which is an unusual, and thus expensive, size - filters =
generally run about $25 each - that is not readily available other than =
online. During construction, my general contractor just had a cheap =
20=E2=80=9D x 25" x 1=E2=80=9D filter in there that seemed to work just =
fine. I checked the installation instructions for the furnace and there =
are no specifications for the filters, other than that they need to be =
changed regularly, which is getting pretty expensive. Is there any =
reason I couldn=E2=80=99t just use 1=E2=80=9D filters, which are less =
than half the price? Maybe even put two of them in the box, a good one =
first to catch most of the dust and a cheap one like the contractor used =
as a secondary one. It is a snug fit and I don=E2=80=99t think there is =
any danger of them tipping, but two would make it impossible.
Thanks,
