I'm not sure how fresh air, or oxygen, gets inside my house other than through cracks of window or door on a cold winter day when the central heating system is on.
I have a pipe that is coming from outside in my basement and delivers air to my basement (there is no fan in it or anything just a pipe by itself). And I think that is meant for providing fresh oxygen for the gas furnace to burn. However, since it is not directly connected to the furnace air intake vent ( a white J-shaped pipe), there will be some outside fresh air delivered to my basement, but in no way is that an effective way of delivering fresh air to the whole house.
So I'm asking this question because sometimes I feel suffocated even when the central fan is on in my house, and I have already positioned myself to be near the vents to make sure there are air flowing around my head. I can't really open the window because my window is facing a neighbor who constantly burns his wood in his old fashioned furnace when produces black smoke that blows towards my window. Our basement outside air intake place is somewhat more discrete, though. Which is why I'm not smelling smoke when all windows are closed.
So I'm asking, is there no other way of getting fresh air inside my fresh air, by using the furnace? Or is an average house supposed to be have fresh air intake systems? I'm in no way an HVAC expert, I might be making wrong presumptions in my question, but any help would be appreciated :)
