Question Old Milwaukee Thermoflo Furnace Filter? HELP!

So I recently moved into a house (I'm renting) and it's getting chilly so time to turn on the furnace but I wanted to replace the furnace filter first.

Went to the basement to look at the beast and jeez I feel dumb 'cause I can't find the filter anywhere!!

It's an OLD Milwaukee Thermoflo Furnace. Model 1203-C11. Serial# 68931.

I just need to know the size of the filter and where it goes! I've looked online for a manual too and come up with nothing. Any help you could give would be appreciated.

Hi ur:

Look in the house for the return air grille. See if the filter is in there. Is the furnace gas or oil fired?

Start by finding the cold air return. Then look for a cover plate between it and the furnace. If you find one, open it and the filter should be inside. If you can't find an external opening, open the front of the furnace where the blower motor is. Sometimes the filter is in that area. Once you locate it, it should have the size printed on it.

Have you actually found and accessed the blower compartment?

I am guessing you may have an old Low-Boy model, and you go on the back side, chances are there is a door that lifts up, or a handle that you turn to open this upper door, the filter should be in there.

Otherwise, take a photo for us to see.
