Yes, I guess you are right about the apartment permissions (I wasn't aware of the exact living situation). But given the speed at which volatile molecules move and the quantity (that's expressed in my layman's terms!), you'd have to have a fair old movement of air between one's nose and the pot or the chair to prevent smelling the object. Maybe this is the answer, without the foot and hand coverings, but the rest is probably necessary to properly seal off the head (nose) and maintain the external air supply purity.
When it comes to eating, I guess the food would have to be liquefied and taken via a straw directly into the mouth, to prevent odour reaching the nose.
