Heater Smell

Occassionally when my heater turns on, there is an unpleasant smell that comes out of the vents. I think it may be mold. The filter on the heater was about three months old when I started noticing this (I bought the house this summer, though). I replaced the filter, and it seemed to get better for a while, but now it is back after a couple weeks.

I think I have a heat pump (that's what the thermostat indicates).

Does anyone have a suggestion on what I could do to look into this, how dangerous it might be to be breathing, and/or how much it would cost to get fixed?

Thanks
