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.

I'm no expert. But we had the same problem. My local hardware store
sells the big fiber mat, though, so we just bought that and cut our own
filter. We get about two filters out of the mat.

BUT, and I don't know if it makes any difference, there are a lot of
loose fibers after you handle and cut that green stuff, so we always
run the vacuum hose over it a couple of times before installing.
Goodluck,
tina

Perhaps get the next size down standard filter and make a cardboard
frame to fit from box cardboard.

I would pick up a 16 x 25 and see how it fits it is possible it
stretched and that made it longer and narrower!

The filter doesn't have to fit flat, in fact, many
filters have a / installation with an angle of
20- 70 degrees others have a /\ installation.
Actually, the steeper the angle the more air flow
and filtering surface. So, if you can put it in
at an angle, a 14 x 30 should work. If it has to
be flat just cut 3 inches off and tape the end
with whatever type of tape you want to use.

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
alt.hvac.

Well so I measured the rack size, 13x23" Not exactly what I had hoped for,
but that's what the dimensions work out to.

So I decided to cram a 14x24 in there until I can figure something out. I
tried a 12x24 and that was way too skinny, so skinny it wasn't wide enough
to be held by the filter supports. I ought to take a pic of it, because I
swear it should be 14x27 but there is a retaining loop that cuts into the
filter rack.

I would have totally thought that residential furnace filters would be
standard sizes.
