Does continuous running cost much more? Yes, several times more, and it produces a worse result. Everybody in the house adapts within an hour, so most of what a continuously running machine releases is not perceived by anybody present.
How much fragrance does a cycle use? Three to six drops per tank for Hotel Collection at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml. Two short cycles a day makes the daily cost small.
The number you want is rupees per day, and it is small
The honest structure of this answer is that the running cost of a machine like this is almost entirely fragrance, and that the fragrance consumption is set by the owner rather than by the device. There is no filter to replace, no cartridge to buy, no consumable other than the fragrance itself, and the electrical draw of a cold-air unit running short cycles is small enough that it does not meaningfully feature in the arithmetic of a household that is also running air conditioning. So the useful version of this question is what makes fragrance consumption go up, and there are three answers in descending order of importance. Cycle length is first, and it dominates everything else. A machine running two short cycles a day is releasing material for a small number of minutes; a machine left running continuously is releasing for many hours. The difference is not a small percentage, it is a multiple, and it is the single reason some households find home fragrance expensive while others barely notice the cost. What makes this worth taking seriously is that the expensive arrangement also produces the worse result. Human olfactory adaptation means that anybody who has been in a space for about an hour stops perceiving its background register almost completely. A machine that runs all day is therefore producing, for most of the day, a level that nobody in the house can detect, at full material cost. Meanwhile the material is settling into curtains, rugs and upholstery, which continue releasing it, so the house accumulates a load that only visitors can perceive. Continuous running is the arrangement that produces both the largest bill and the heaviest house, which is an unusually clear case of a setting being wrong on every axis. Intensity is second, and it behaves as expected: a higher setting uses proportionally more. The thing worth saying about intensity is that the correct level is almost always lower than people first choose, because they set it while adapted. Setting the level on a day when you have just come in from outside, and then leaving it alone, tends to produce a setting one or two steps below what the same person would have chosen at eight in the evening, and both the house and the running cost benefit. Connected volume is third. A larger joined-up space simply needs more material to reach a perceptible level, which is arithmetic rather than a problem, but it is worth noting that this is a reason to run with internal doors closed when building a level for an occasion. A cycle released into a house with every door and terrace door open is filling a much bigger and constantly exchanged volume, so it uses more and achieves less. Now the two structural ways to reduce running cost without reducing the result, which are more useful than any setting change. The first is to run before the moments that matter rather than during them. The value of a fragrance layer is concentrated at arrival, because arrival is the only time anybody perceives a house properly. A cycle that finishes shortly before people come home or guests arrive delivers essentially the whole benefit; a cycle that runs through the evening delivers almost none of it to people who have adapted, while consuming continuously. Anchoring cycles to arrivals rather than to hours is the single most effective economy available. The second is to let passive sources carry the constant load. The entrance and the bathrooms want a permanent low presence rather than a scheduled one, and a reed diffuser does that at a fixed cost of Rs 749 to Rs 849 for three to four months, with refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Using the machine for the connected living volume and reeds for the fixed positions is both the cheaper arrangement and the better one, because the positions that benefit most from constancy get constancy, and the machine is not asked to run all day to compensate. One final note that belongs in any cost discussion. A machine cannot substitute for extraction, cleaning or a drain trap that needs a mug of water in it. Money spent on fragrance to cover an unaddressed cause is money spent on a worse outcome than doing nothing at all.
What running it actually involves
What running it actually involves. The machine: the SOSA Vaayu at Rs 11,999, a waterless cold-air unit with no water tank, no filters and no cartridges, coverage up to 1,000 m², Bluetooth app and timer control. The only consumable is fragrance: Hotel Collection at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, used at three to six drops per tank, rinsing between scents. The setting that decides the cost: two short cycles a day rather than continuous running, anchored to arrivals rather than to hours, and finishing before the moment rather than running through it. Set the intensity on a day you have just come in from outside, which almost always produces a lower and better setting than one chosen in the evening. Build levels with internal and terrace doors closed, since a cycle released into an open house fills a much larger and constantly exchanged volume for less effect. Let the fixed positions run passively at a low fixed cost instead of asking the machine to run all day: reed diffusers in the entrance and every bathroom - 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. Smaller connected space: the SOSA Megh at Rs 3,499 with a 6L tank or the SOSA Sukoon at Rs 1,799. Hotel Collection is a water-based fragrance for ultrasonic diffusers and is not reed diffuser oil; the two are not interchangeable. Never scented: the kitchen at any time, the dining area, children's rooms, and covered terraces and balconies. Everything is alcohol-free and made to IFRA-compliant standards.

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.
