Ive always found doing somehting like blades or lungs is the best, as all the smoke is going straight into your lungs and then into the C7 cannister (gasmask filter) and then out the window. A fan going, maybe some airfreshner if nescasary. Pretty much everything said above. I personelly hate incents so i dont burn them, but i will burn oils or whatnot. I find this stuff i have thats like room perfume is really good, i just put it onto a hot lightbulb and it fills up the room nice, plus it sticks around for a while (the nice smell). Having a smoke after always helps.
