Why not give one monthly number? Because the two halves behave differently. Bottles have a fixed life; a machine's consumption changes several times over depending on how long its cycles run.
What is the biggest cost lever? Cycle length. Two short cycles a day cost a fraction of continuous running and deliver essentially the whole benefit, because everybody indoors adapts within an hour.
Two halves, and only one of them is a number
A 2,000 square foot home is the first size where the monthly consumption question splits cleanly into two halves that behave completely differently, and it is worth separating them rather than averaging them into a single figure, because averaging is where this question usually goes wrong. Half one is the bottles, and it is exact. A home this size typically runs five to seven reed diffusers: one in each bathroom, one in each bedroom at the lightest level in the home and from a source the occupant can move or cap, one in a study if there is one, and one just inside the entrance - which is the highest-value position in the house, because everybody living there has adapted to the background and perceives very little, making arrival the only moment anybody experiences the home properly. Each bottle serves its room for three to four months, and that is a property of the product rather than a setting somebody chooses. So the arithmetic is genuinely yours to do: bottles run from Rs 749 for Morning Freshness through Rs 799 for Garden Bloom and Evening Calm to Rs 849 for Fresh Brew and Mountain Breeze, and at a three to four month life each works out at roughly a fifth of its price per month. Refills lower it further, at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Nothing else in that half is consumed at all - no electricity, no filters, no cartridges, no water. Half two is the machine, and it is not a number, which is the part we want to be straightforward about rather than vague. A machine's fragrance consumption is driven overwhelmingly by cycle length and secondarily by intensity. Both of those are settings the owner chooses. The same Megh at Rs 3,499 in the same living room in the same house will consume a small quantity if it runs two short cycles a day and several times that if it is left running continuously - and the difference is not marginal, it is a multiple. So any millilitre-per-month figure we published would be a statement about our assumed settings, not about your home, and it would be wrong for most readers. Some brands publish one anyway. We would rather tell you what actually determines it. What we can state accurately is the dosing and the products: 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, with the tank rinsed when changing scents. 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 we can tell you the one lever that decides your machine bill, which is cycle length. Continuous running is expensive on two counts and worse on a third. It multiplies consumption several times over. It accumulates material in curtains, rugs and upholstery, which release it slowly, so the house builds a background load. And it delivers almost nothing to the people in the house, because olfactory adaptation is close to complete within about an hour - a machine running all afternoon is releasing fragrance that nobody present can detect. Two short cycles anchored to arrivals rather than clock hours deliver essentially the whole value of the layer, because the value sits in the moment somebody walks in from outside with an unadapted nose. That single change usually cuts machine consumption to a fraction of what it was, and improves the result. If you want a real figure for your own machine, tell us your cycle settings on WhatsApp - how many cycles, how long, at what intensity - and we will work it against those rather than against an average. Finally, the two things that cost nothing and matter more than the entire bill at this size: extraction over the hob used every single time with the kitchen door shut, since cooking smell is aerosolised oil that settles into the same textiles that hold your fragrance, and a mug of water down the drains of any bathroom not used daily, since a dried trap is the commonest bad smell in a house this size and no quantity of fragrance addresses it.
The split, stated honestly
The split, stated honestly. Half one, exact and yours to calculate: five to seven reed diffusers - one per bathroom, one per bedroom at the lightest level in the home from a source the occupant can move or cap, one in a study, and one just inside the entrance - 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, each serving a room for three to four months, which is roughly a fifth of the bottle price per room per month, and less again on refills at Rs 2,399 for 300ml and Rs 3,499 for 500ml. Nothing else in that half is consumed: no electricity, no filters, no cartridges, no water. Half two, a setting rather than a number: the SOSA Megh at Rs 3,499 with a 6L tank for the connected living volume, or the SOSA Sukoon at Rs 1,799 for a compact hall, consuming according to cycle length and intensity rather than to your square footage. What we can state accurately: 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 - a water-based fragrance for ultrasonic diffusers, not reed diffuser oil, and the two are not interchangeable. The lever that decides the machine bill: two short cycles anchored to arrivals rather than continuous running, which multiplies consumption several times over, accumulates in curtains and upholstery, and delivers almost nothing to people who adapted within the hour. Set the level on a day you had just come in from outside. For a real figure, send your cycle settings on WhatsApp and we will work it against them rather than against an average. Costing nothing and mattering more than the whole bill: extraction over the hob used every single time with the kitchen door shut, and a mug of water down the drains of any bathroom not used daily. 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.
