Yes to the same fragrance - but size is the wrong axis for intensity

The first half of this question has a settled answer and the second half has a widely believed wrong one, so it is worth separating them. Same fragrance across every store: yes, without qualification. The register is the asset, it should be identical in every branch and every room, and it should be varied only in level. Customers of premium brands travel, and a difference between branches reads as an inconsistency rather than as thoughtful local variation. That part is not in dispute. The second half - that intensity should scale with store size - is intuitive and wrong, and using size as the axis produces two errors at the same time. The correct variable is how the room is used, and specifically how long people stay in it, because intensity should be set inversely to exposure time. A customer moving through a trading floor for ten or fifteen minutes and a family sitting in a consultation room for an hour or two are two entirely different exposure problems, and they want two different settings regardless of how many square feet surround them. So a consultation cabin takes the same low level whether it sits inside a 500 square foot boutique or a 5,000 square foot showroom. A trading floor takes the working level at either size. A bridal room takes the lowest level in the building at either size. A cabin is a cabin. Now the first error that size-based thinking produces: the belief that a larger store needs a stronger setting. It does not. What a larger store needs is more provisions, because a machine distributes through connected moving air and cannot cross a closed door, and a larger store almost always has more separated spaces - more cabins, an office, an accounts room, a strongroom lobby, sometimes another floor. Coverage of zones is the missing ingredient, not strength. This matters commercially, because the wrong diagnosis leads to an upgrade that does not fix anything: a bigger machine on the shop floor of a store whose problem is three unserved cabins produces a stronger shop floor and three cabins that are exactly as they were. The correct response is more provisions, and the extra ones are usually cheap - reeds at Rs 749 to Rs 849 with three to four months from a bottle and refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml, which hold a low continuous level with nothing to switch on. The second error runs the other way: the belief that a small store can run everything at one level because it is small. It cannot, if it has a room behind a door. A cabin in a compact boutique still holds somebody for an hour with the least air movement in the building, and still needs the lower setting. In fact small stores are more likely to get this wrong, because the whole space feels like one room and the cabin is treated as part of it - and because in a compact store the machine tends to end up on the counter, where the socket is, producing the strongest air in the building exactly where a staff member stands all day and where every customer leans in over a tray. So the working model for a group with stores of different sizes is: scale the number of provisions with size and complexity, and set each provision by the use of the room it serves. In practice that produces a simple table that can be written once and applied everywhere. Entrance and circulation: the working level, and never stronger than the floor - the entrance is where a customer's nose is unadapted and where the whole assessment happens in the first six seconds, so it needs accuracy rather than strength. Trading floor: the working level. Any room behind a door where people sit: lower. Bridal and long-appointment rooms: lowest in the building. Staff quarters, store rooms and utility areas: nothing at all. That table is portable across a 500 square foot boutique and a 5,000 square foot showroom, and it is far more useful than a rule based on area. There is one way in which size legitimately enters, and it is about hardware class rather than intensity. A larger open floor needs a machine capable of covering it, because reeds work by passive evaporation at a fixed rate and an open floor above roughly 1,000 square feet replaces its air faster than they can supply it. So the Boond at Rs 799 suits a small room, the Sukoon at Rs 1,799 a compact floor or a large cabin, the Megh at Rs 3,499 with its 6L tank a substantial floor - the larger tank mattering for refill frequency rather than reach - and the Vaayu at Rs 11,999 a large open showroom, waterless with no tank at all, coverage up to 1,000 square metres or roughly 10,700 square feet, with Bluetooth app and timer control. But note that this is about which unit can serve a space at all, not about running it harder. And buying up is not neutral: a machine covering up to 1,000 square metres placed in a 500 square foot shop is roughly twenty times the coverage the room can use, and the practical consequence of over-capacity in a small space is a hotspot rather than a better atmosphere. Two further rules apply at every size. Run continuously at a low setting rather than in strong bursts, because bursts produce a swing between too much and nothing, and in a small room that swing is more noticeable while in a large one a burst released during a still period simply stays where it was released. And lower every level in humid months, because humid air carries fragrance more slowly and clears it less readily, so a setting judged well in a dry month reads considerably heavier in a wet one - a change of level, never a change of register. Judge each level by having somebody who does not work in that building walk in from the street at the busiest hour and read the first three or four seconds: clean is right, scented is too high. Nobody inside can do it, because everybody adapts to a steady background within about an hour of arriving and stops perceiving it, which is also why staff requests to increase a setting are honest, near-universal and almost always wrong. On register, Quiet Luxury, with white tea, bergamot and cedar, is the safest across a mixed estate; White Tea Serenity, with white tea, aloe and cedar, is the softest and is the correct partner in enclosed rooms, being the same family read quieter; Forest Suite, with cedarwood, vetiver and green leaves, suits timber-led stores; Old-World Glamour, with amber, violet and woods, suits warm gold-led floors and should be kept out of small rooms; Warm Welcome, with citrus, floral and sandalwood, is an entrance register; Tea Garden, with jasmine, green tea and white tea, is a soft green-floral; and Lobby Bar, with citrus, pepper and amber, is characterful and suits circulation. Machines take the water-based Hotel Collection at three to six drops per tank with a rinse between scents, never reed oil, which can damage them. Fix sources at every size: the pantry is never scented at any time, since cooking smell is aerosolised oil and extraction is the answer; washrooms need working extracts; and unserviced air conditioning will be smelled - and in a small store there is nowhere for any of it to hide. Staff should have a physical off switch and never have to justify using it. We make no claim that fragrance affects mood, comfort, dwell time, purchase behaviour or spend. The seven registers are Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, and they are SOSA's own interpretations - we are independent and not affiliated with, endorsed by or associated with any hotel brand. Everything is alcohol-free and made to IFRA-compliant standards, and a portion of every order supports girl-child education through Nanhi Kali. Volume pricing is quoted against the specification on WhatsApp.

Use decides the level, not floor area

The first half is settled: the same register in every store, varied only in level, because the register is the asset and customers of premium brands travel. The second half - that intensity should scale with store size - is intuitive and wrong, and produces two errors at once. The correct variable is how the room is used, specifically how long people stay in it, because intensity runs inversely to exposure time. A customer moving through a floor for fifteen minutes and a family seated for two hours are different problems wanting different settings regardless of the square footage around them. So a consultation cabin takes the same low level in a 500 square foot boutique as in a 5,000 square foot showroom; a trading floor takes the working level at either size; a bridal room takes the lowest level in the building at either size. The first error is believing a larger store needs a stronger setting. It needs more provisions, because a machine cannot cross a closed door and a larger store has more separated spaces - more cabins, an office, an accounts room, a strongroom lobby, sometimes another floor. Coverage of zones is the missing ingredient, not strength, and the wrong diagnosis leads to an upgrade that fixes nothing: a bigger machine on a floor whose problem is three unserved cabins produces a stronger floor and three unchanged cabins. The extra provisions are usually cheap - reeds from Rs 749, three to four months a bottle, holding a low continuous level with nothing to switch on. The second error runs the other way: that a small store can run everything at one level. It cannot, if it has a room behind a door, and small stores get this wrong more often because the whole space feels like one room and because the machine ends up on the counter, where the socket is and where staff stand all day. So: scale the number of provisions with size and complexity, and set each by the use of the room it serves. That produces a portable table - entrance and circulation at the working level and never stronger than the floor, since the entrance holds the only unadapted nose; trading floor at the working level; rooms behind doors lower; bridal and long-appointment rooms lowest; staff quarters, stores and utility areas nothing. Size enters legitimately only as hardware class: reeds cannot carry an open floor above roughly 1,000 square feet, so SOSA Boond Rs 799 for a small room, SOSA Sukoon Rs 1,799 for a compact floor or large cabin, SOSA Megh Rs 3,499 for a substantial floor, SOSA Vaayu Rs 11,999 with coverage to 1,000 m² for a large open showroom - and buying up is not neutral, since over-capacity in a small room makes a hotspot. Run continuously at every size, and lower every level in humid months. From Rs 299 for 15ml. Everything is alcohol-free and made to IFRA-compliant standards. Volume pricing is quoted on WhatsApp.
