My cat box is in the basement and it seems the oder sometimes gets into
the air blower. Would it hurt anything if I sprayed the air filter
with Febreeze or some other air freshener? Since the air is blowing
out of the blower into the filter I don't see how this could hurt
anything. My only concern is during the winter when the furnace goes
on that if the air freshener is flammable it could ignite.

Thanks!!
