do all furnaces have air filters?
Forced air furnaces (gas, oil, propane) all have filters. Wall mounted heaters/furnaces genereally do not. Boilers do not.
If you have a forced air furnace and run it without the filter the furnace will get damaged due to dirt, dust getting into the system and you will be breathing dirty air constantly. Thats not good for the lungs and respiratory system.
