Furnace filter for Carrier model 58DHB055-CC

I'm trying to find air filters for a Carrier model 58DHB055-CC. Evidently there are supposed to be two filters that sit in the return-air plenum above the blower in a V configuration. Is there a part number for this filter? Perhaps a larger filter that can be cut down to size? I haven't been able to find any information about this furnace on the internet. I don't even know how old this furnace is. Presently, the furnace is running without any filters at all. (Is this a terribly bad thing to do?).

This furnace was produced from 1984 - 1998 and this filter is a "field supplied" item. If you do not have a filter, your indoor blower and motor will become clogged with dust bunnies. These intern will plug up air holes in the motor, and clog the blower wheel reducing performance. If you have air conditioning, it'll even be worse. The indoor cooling coil will [which already would be] become clogged as well. Check to see if the return grille is hinged, and can house a filter.

Take a tape measure. Turn the electric off to the heater. Open the back door. Measure the width of the inside compartment. Measure the height of one of the brackets that are spot welded to the compartment. You should come up with some standard size (with no fractions of an inch). Do not use the kind you cut to size. Get ones with a cardboard frame, and get the cheap kind. Do NOT get those pleated high-efficiency kind. Running without filters is good for the HVAC service industry, motor manufacturers, and doctors. If someone in the home has allergies, call an HVAC contractor for a price on an electronic air cleaner.

Evidently you should invest in a measuring tape.

Perhaps you should try the yellow pages and call someone that has a clue!

No, air filters are strictly a conspiricy started by the filter manufacturers to boost sales.

Buy a case of the cheap kind with a cardboard frame. Do not use the kind you cut to size. They will fall into the blower unless you know how to properly reinforce them. Do not use those pleated high efficiency ones.

Thanks for the advice. 14x20x1 filters did the trick. It's quit a tight fit, scooting the filter up pass the blower, but it worked. The Carrier design certainly doesn't encourage filter replacement!

Bob, The Carrier 58DH doesn't need filters. It was designed to automatically eradicate any dust with a new lithium mercury UV-C interior ballast. If only they would make cars that way Bubba
