Should Double-Height Living Rooms Be Treated as Separate Scent Zones?

Yes, and the reason is not the one people expect. A double-height living room gets treated as a scaling problem - the room is twice as tall, so double something. The more useful view is that it is two rooms stacked on top of each other doing entirely different jobs, and only one of them has people in it. Measure honestly: two people on a sofa occupy a band about five feet deep off the floor, and somebody walking through occupies six. Everything above that line, the next fourteen or fifteen feet of a typical Indore double-height living room, is a view. A chandelier, tall glazing, a run of stone, the underside of a gallery. It is one of the best things about the house and nobody is ever in it.

That changes the question from how much to where. A source mounted at head height on a tall wall, or put on a high ledge because the ledge was there, sends most of its output into the half of the room nobody inhabits. What follows is predictable: it reads as weak from the sofa, somebody turns it up, and now the occupied band finally carries something while the volume above it carries a great deal more than anyone intended. And there is a second reason to stay low that matters more than efficiency. In almost every double-height plan the upper volume is not sealed - it opens onto the gallery, the landing and the corridor with the bedroom doors on it. Bedrooms and children's rooms carry nothing at all, so the tall volume is not a space to fill. It is the connection to the part of the house that is deliberately excluded.

So the practical answer is short. Mount low, on the wall the seating faces, at about console height rather than picture-rail height. Aim across the seating group instead of into the middle of the room. Set the level sitting down, in the chair somebody actually uses in the evening, and key-lock it there. Then accept the honest limitation: the register will read where people sit and fade as they walk toward the stairs, which is correct behaviour rather than a fault.

Fragrance does not remove or reduce anything in the air, it treats nothing and relieves nothing, and I make no claim that it does. It works alongside ventilation and cleaning, never instead of them. Bedrooms and children's rooms are never scented, and nothing runs unattended overnight. One named room stays genuinely fragrance-free so anybody in the household has somewhere to go. Any household member's preference overrides any plan, a child's or a guest's included, and one objection ends it.
