Are there other running costs? No. There are no filters or cartridges, and the electrical draw of a cold-air unit running short cycles is negligible beside the rest of a household.
Why will you not publish a machine figure? Because it would be a statement about assumed settings rather than about a real home. We quote it against actual cycle settings instead.
What we will state, and what we will quote
This page sets out everything we can state accurately about monthly running cost, and marks clearly the one part we will not invent. Start with what running cost consists of, because the answer is narrower than people expect. It is fragrance, and effectively nothing else. There are no filters to replace on any of our machines. There are no cartridges to buy. The electrical draw of a cold-air unit running short cycles is not a meaningful line item next to a household that is also running cooling and lighting, and a small tank's water use is not worth counting. So the whole question reduces to how much fragrance you use, and that splits into two halves that behave completely differently. The exact half is the reed diffusers, and you can calculate it yourself precisely. A reed bottle serves one room for three to four months. That is a property of the product rather than something that changes with how you run it, which is what makes the arithmetic possible. Bottles run Rs 749 for Morning Freshness, Rs 799 for Garden Bloom and Evening Calm, and Rs 849 for Fresh Brew and Mountain Breeze, so each contributes roughly a fifth of its purchase price per month. Refills improve the rate at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Multiply by your room count and you have your figure: three or four bottles in a compact flat, five to seven in a 2,000 square foot home, eight to ten in a 3,000 square foot villa, twelve to sixteen in a very large one. It is a small and highly predictable number, and it is the majority of most households' fragrance spend. The quoted half is the machine, and here we mark the boundary rather than guess across it. Machine consumption is driven overwhelmingly by cycle length and secondarily by intensity, and both are settings the owner chooses rather than properties of the home. The same unit in the same room can differ by a large multiple between two short daily cycles and continuous operation. Any millilitre-per-month figure we published would therefore be a statement about our assumed settings, not about your house, and it would be wrong for most people who read it. We would rather not publish a number that is mostly about us. What we will state accurately is the dosing: Hotel Collection is used at three to six drops per tank, priced at Rs 299 for 15ml, Rs 999 for 100ml and Rs 1,799 for 300ml, with the tank rinsed when the fragrance changes. It is a water-based fragrance for ultrasonic diffusers and is not reed diffuser oil; the two are not interchangeable and reed oil can damage a diffuser. And if you send us your actual cycle settings on WhatsApp - how many cycles, how long, at what intensity - we will work a real figure against them. Now the part that is more useful than any number, which is where the savings actually are, in order. First, cycle discipline, which saves more than everything else combined. Two short cycles a day anchored to arrivals rather than clock hours, instead of continuous running. This is not merely cheaper, it produces a better result: everybody in a house adapts within about an hour, so a machine running all afternoon is releasing fragrance nobody present can detect while it accumulates in curtains and upholstery for visitors to notice. In a large volume, fewer and longer cycles rather than several short ones, because a big room decays slowly and short cycles stack, ratcheting the level upward through the day while consumption multiplies. Second, refills rather than fresh bottles, which is a straightforward better rate on the exact half of the bill. Third, and most overlooked: no bottles in rooms nobody uses. A spare bedroom or unused guest bathroom does not have a fragrance deficit - it has a dried drain trap, where the water seal evaporates within weeks and connects the room to the drainage system, and still air. A mug of water down every drain including the floor drain, plus hours of airing with the door and wardrobe open, fixes what is actually wrong at no cost and removes that room from the standing bill. In a villa that can be two or three bottles. Fourth, set intensity once on a day you have just come in from outside and leave it alone, because every later adjustment is made by an adapted nose and runs upward. And finally, the item that never appears on any fragrance bill and outranks everything on it: extraction over the hob used every single time with the kitchen door shut. Cooking smell is aerosolised oil that settles into exactly the textiles that hold your fragrance, and no monthly spend addresses it.
The whole picture, honestly
The whole picture, honestly. What running cost consists of: fragrance, and effectively nothing else - no filters, no cartridges, and an electrical draw that is not a meaningful item beside the rest of a household. The exact half, yours to compute: reed diffusers serving one room each for three to four months - 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 - roughly a fifth of the bottle price per room per month, with refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Three or four bottles in a compact flat, five to seven at 2,000 sq ft, eight to ten at 3,000, twelve to sixteen in a very large home. The quoted half: machine consumption driven by cycle length and intensity rather than by house size, using 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 - a water-based fragrance for ultrasonic diffusers, not reed diffuser oil, and the two are not interchangeable. Send your actual cycle settings on WhatsApp and we will work a figure against them. Where the savings are, in order: cycle discipline first, with two short cycles anchored to arrivals rather than continuous running, and fewer longer cycles in a large volume rather than several short ones that stack; refills rather than fresh bottles; no bottles in rooms nobody uses, which need a mug of water down every drain and hours of airing instead and which in a villa can remove two or three bottles from the standing bill; and intensity set once on a day you had just come in from outside, then left alone. The machines: the SOSA Vaayu at Rs 11,999 where the plan is genuinely open, the SOSA Megh at Rs 3,499 with a 6L tank, the SOSA Sukoon at Rs 1,799 for a compact hall, the SOSA Boond at Rs 799 at the door. Never on any bill and outranking everything on it: extraction over the hob used every single time with the kitchen door shut. Never scented: children's rooms, the kitchen at any time, the dining area during a meal, 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.
