So I was gonna replace my gas furnace filter today before the cold
weather starts, or at least the cold night weather. But for the life
of me I can't find any information on or about my gas furnace - except
for the brand and the date of installation. Heck, even the filter is
one of those freeform washable filters that doesn't have a cardboard
border with the dimensions on it (basically just a rectangular mat of
green fibers that is totally impregnated with dust and looks about a
useful as a third tit). So I took it out and measured it - it comes
out to be 14x27

So I go out looking for a filter for it and no one I know of sells
anything even remotely like that size, 14x30 14x24 14x25 but not 14x27.

So anyway I have a Payne furnace installed in 1983, there is a wiring
diagram on the inside of the filter cover and that give a model number
of 397H or 375A but that's it. There's nothing on the outside of the
furnace and nothing that I could see on the inside where the motor and
burners sit.

So what's the story, the Payne homepage is about a useful as a 4th tit
and I couldn't pull anything up about a 375 or 397.

Yeah but the thing that bothers me is that NONE of the filter sites let
you search by FURNACE - which would be more helpful.


Measure the rack that holds the filter, not the filter itself. It should
be a shade more than one of the numbers you found at Filters Now


Thank you that's the best information I've managed to glean from here and
