When is two justified? When two separate floors each contain a living area people genuinely sit in, such as a hall below and a family lounge above.
Is three ever right? Almost never. It would require three separate floors each containing an occupied living volume, which is rare even in large houses.
One, usually. Two only if two floors are lived on
The answer is usually one, and it surprises people because three floors sounds like it should need three of something. The counting method is what makes it clear: count the floors that contain a living volume people actually occupy, not the floors that exist. A living volume is a body of connected air where people sit - a hall, a dining area open to it, a family lounge. It is not a bedroom, which is a sealed room behind a closed door that no machine crosses at any price. It is not a landing, which is somewhere people walk through. And it is not a service level. Run through a typical three-storey Indian house on a narrow plot, because this layout is extremely common and almost no fragrance advice accounts for it. The ground floor is frequently a service level: parking, a utility and washing area, a store, the staircase, sometimes a room let out or kept for staff. There is no living volume there at all, and a covered parking area cannot hold fragrance in any case, because the air exchanges continuously with the street in exactly the way a covered terrace does. So that floor takes nothing. The first floor is usually the actual living floor: hall, dining area, kitchen, sometimes a bedroom. That is one living volume, and it is where the machine belongs. Test it there rather than at street level: walk that floor at an ordinary hour, changing nothing, and count the closed doors between the hall, the dining area and the stair landing on that level. Zero closed doors means one connected volume and the Vaayu at Rs 11,999 qualifies - waterless, so nothing to fill before an evening or empty afterwards, with app and timer control. A compact hall on that floor takes a Sukoon at Rs 1,799. A partly open arrangement takes a Megh at Rs 3,499 with its 6L tank. And if that floor is itself compartmented, with a closed hall and a separate dining room, then no machine qualifies there either and bottles serve the house better. The second floor is bedrooms, their bathrooms and a landing. There is no living volume there. Every bedroom is sealed and every bathroom permanently so, and a landing is a walkway. So that floor takes reeds: one per bedroom at the lightest level in the home, from a source the occupant can move, cap or take out of the room without asking anybody, one per bathroom, and one on the landing. Total: one machine. Two machines are justified when two separate floors each contain a living area that people genuinely sit in - for example a hall on the first floor and a family lounge or open study on the second. That is a real case in larger houses and it deserves a second unit, sized to that space, with a Sukoon at Rs 1,799 usually being right. It should be its own source rather than an attempt to feed one floor from another, because a stairwell carries only a weak trace whose direction changes with roof heat, air conditioning and open windows, so raising the lower unit overdoses the floor you are standing on - invisibly, since everybody in the house has adapted within the hour - while delivering very little above. Three machines is almost never right. It would require three separate floors each containing an occupied living volume, which is rare even in large houses, because one of the three is nearly always either a service level or a bedroom floor. If you find yourself considering a third, check what it would actually serve: if the answer is a landing, a bedroom corridor or a parking area, it has nowhere useful to go, and the same money does far more as bottles for the sealed rooms, better fragrance, and spares so nothing lapses. Two placement notes that matter in any multi-storey house. Do not put the machine at the foot of the stairs: a stairwell is a continuous outflow, so a source beside it feeds the opening rather than the room. And keep one register throughout the whole house, because something is moving between floors most of the time and two registers meeting in the column produce a third nobody chose.
Count the floors people live on
Count the floors people live on. A service ground floor of parking, utility and stores: nothing at all, and covered parking cannot hold fragrance because the air exchanges continuously with the street. The living floor, wherever it actually is, tested with a closed-door walk on that level: the SOSA Vaayu at Rs 11,999 if zero doors separate hall, dining and landing - waterless with no tank, coverage up to 1,000 m², Bluetooth app and timer control; the SOSA Sukoon at Rs 1,799 for a compact hall; the SOSA Megh at Rs 3,499 with a 6L tank if partly open; and no machine at all if that floor is itself compartmented. Place it in the body of the hall, several metres from the stair opening, at console or table height and out of the direct throw of an air conditioner. The bedroom floor: no machine, because there is no living volume - one reed diffuser per bedroom at the lightest level in the home from a source the occupant can move, cap or take out without asking anybody, one per bathroom, and one on the landing - Morning Freshness at Rs 749, Garden Bloom at Rs 799, Evening Calm at Rs 799, Fresh Brew at Rs 849, Mountain Breeze at Rs 849, three to four months per bottle, refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml. A second machine only where two separate floors each contain a living area people genuinely sit in, as its own source and never as a raised setting below: the SOSA Sukoon at Rs 1,799. Never a machine on a landing, in a bedroom corridor or in a parking area. The entrance that matters, which is the door into the living floor: a reed or the SOSA Boond at Rs 799, permanent rather than scheduled. One register throughout the whole house, since something moves between floors most of the time and two registers meeting produce a third nobody chose. Fragrance for machines: Hotel Collection at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, at three to six drops per tank, rinsing between scents; it is not reed diffuser oil. Never scented: children's rooms, the kitchen at any time, the dining area during a meal, utility and store areas, and terraces. Everything is alcohol-free and made to IFRA-compliant standards.
| Scent | Why it suits the mood |
|---|---|
| Service ground floor | No living volume. Nothing at all, and parking holds nothing |
| Living floor · ₹11,999 | One machine. Test the closed-door walk on that level |
| Bedroom floor · from ₹749 | No living volume. Reeds per room and one on the landing |
| Total | One. Two if two floors each have a lounge people sit in |

Versailles
Most customer gifts are bought to be handed over, not to be kept: the sweet box is finished by the family that evening, the keychain joins a drawer, the branded pen was never really a gift at all. Then the moment that cost your business lakhs to create - the new car, the new home, the big purchase - is remembered with nothing. A fragrance gift keeps that moment alive, because scent is the sense wired closest to memory: months later, your customer is still in the middle of the experience you gave them.
I trained at ISIPCA in Versailles and everything we make is built for Indian lives - car diffusers that survive a Mumbai summer, reed diffusers that hold through the monsoon, alcohol-free formulas safe to gift across every customer profile. If you run a dealership, a project, a hotel, a showroom or a team, message the bulk desk on WhatsApp at +91 96192 18531 - tell me the customer moment and the volumes, and I will help you design the programme myself. The business conversations are my favourite kind: one good gifting programme teaches me more about a category than a year of retail orders.
And a part of every order funds girl-child education through Nanhi Kali - so your customer gift quietly gives twice. That equation has always felt right to me.
Frequently asked questions
Facts verified August 2026: Olfactory memory research shows scent-linked memories are unusually durable and emotionally vivid, which is why a used-daily fragrance gift sustains brand association in a way consumable or novelty gifts do not; customer-experience research consistently finds that peak moments (delivery, possession, checkout) disproportionately shape how the whole purchase is remembered. Fragrance preference is personal: volume gifting programmes should default to gentle fresh, green and lightly floral registers, and to space formats (diffusers, reeds, car fragrance) rather than skin perfume.
