In mobile homes the filter is often located in the furnace door. In homes it is normally located to the left, right, or below the blower compartment - sometimes in the furnace itself and sometimes external to the furnace. Filter's also can be located within a ceiling grill or in a wall grill in a location remote from the furnace. These are called filter grills and normally have clips that can be turned to open the door and gain access to the air filter. Standard air filters actually stop only the largest of dust particles, but they serve an even more important purpose. If a large object, such as a postcard, gets into the blower squirrel cage, it can cause the cage to become unbalanced which can cause it to shake the furnace in the same manner as an unbalanced washer or dryer. So it might be a good idea to keep hunting until you find it. Good luck.

Some furnaces don't have them... but all forced-air furnaces have filters. The filter would probably be placed right where the cold air comes back into the furnace. On some models, there is a narrow panel concealing it.
The filter isn't there to protect people from dust -- it's there to protect the furnace motor.

I don't know of any forced air furnaces that don't have a filter. However, gravity feed furnaces do not have a filter.

A repair guy told me not to bother last year because the fine dust goes through anyway.
