Where should it be placed? In the connected volume, at console or table height where air moves, away from a corner and not behind furniture. Never aimed at a dining area, and never in a kitchen.
When should the level be chosen? On a day you have just come in from outside after being away for a while, since that is the only moment you can perceive your own house accurately. A level chosen in the evening will always be too high.
The first thirty days decide the next three years
The mechanical part of setting up a machine like this takes a few minutes and the instructions supplied with the unit cover it. What this page is about is the handful of decisions that determine whether the setup is still correct in a year, because that is where almost all the difference lies between households that are happy with home fragrance and households that quietly stopped. Position first. The machine should sit in the connected volume it is meant to serve, which usually means the main living area, and it should be at console or table height rather than on the floor. This matters more than people expect. Air moves through the upper two thirds of a room, and a source at floor level in a still corner produces a pool of fragrance around itself rather than a distributed level. It should not be tucked behind a sofa or a console, which is where plug-in devices habitually end up and one of the reasons they perform badly. Keep it away from the direct throw of an air conditioner, since a strong directed airstream will carry everything in one direction and produce a gradient rather than a level. And there are two places it should never point: the dining area, because taste is largely smell and food should be the fragrance at the table, and the kitchen, which should never be scented at any time because cooking smell is aerosolised oil that needs extraction rather than competition. Scheduling second, and here the useful principle is to anchor cycles to arrivals rather than to clock hours. The value of a home fragrance layer is concentrated in the moment somebody walks in from outside with an unadapted nose, because everybody already inside has adapted and is perceiving very little. So a cycle that finishes shortly before the household comes home in the evening delivers the whole benefit, while a cycle that runs at a fixed hour when the house is empty is spent on nobody at all. Two short cycles a day is the right default for most homes: one before the house is properly in use, one before the main arrival of the evening. Longer is not better and continuous is actively worse, since it costs several times as much and delivers nothing to people who have adapted, while accumulating in curtains and upholstery for visitors to perceive. Third, keep a separate hosting profile rather than adjusting the daily one. It should start about an hour before guests arrive, run with internal and terrace doors closed so the level builds in the connected volume, and then revert on its own. The reason for keeping it separate is not tidiness. It is that a setting raised for an evening and left is invisible to the household afterwards, because they have adapted, so it persists for months and the house becomes steadily heavier without anybody in it noticing. A profile that reverts removes that failure mechanically rather than relying on somebody remembering. Fourth, fragrance discipline. Hotel Collection is used at three to six drops per tank, and the tank should be rinsed thoroughly when the register changes, otherwise the previous scent sits underneath the new one and neither reads cleanly. Keep a spare bottle, because running out on the afternoon of an evening is one of the commonest ways a routine ends. And do not put reed oil in it: reed oil and the water-based Hotel Collection are two different systems, they are not interchangeable, and reed oil can damage a diffuser. Fifth, and this is the decision that matters most: choose the intensity on a day you have just come in from outside after being away for a few hours. That is the only accurate reading of your own house that you will get, and it will almost always produce a setting one or two steps lower than the same person would choose at nine in the evening. Then leave it alone. Do not adjust it by feel later, because every later adjustment is made by an adapted nose and will therefore be upward. Two things to set up alongside the machine, and both are deliberately outside the schedule. A continuous source at the entrance, because arrival is the only unadapted moment anybody has and it should not depend on a cycle having run. And a reed in every bathroom, including the guest one, which works whether or not the power is on. Also make sure the machine has a physical off switch anybody in the house can reach without needing the app, since everybody in the building shares the air and nobody should have to ask permission to stop smelling something.
Setup, in order
Setup, in order. The machine: the SOSA Vaayu at Rs 11,999 - waterless with no tank to fill or empty, coverage up to 1,000 m², Bluetooth app and timer control - positioned in the connected living volume at console or table height where air moves, out from behind furniture and away from the direct throw of an air conditioner. Two short cycles a day, anchored to arrivals rather than clock hours: one before the house is properly in use, one finishing shortly before the household comes home. A separate hosting profile starting about an hour before guests with internal and terrace doors closed, reverting by itself afterwards. Fragrance: 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 the tank thoroughly when changing register so the previous scent does not sit underneath the new one, with a spare bottle kept in a cupboard. This 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. Set the intensity on a day you have just come in from outside, which is the only accurate reading you will get, and then leave it alone. Outside the schedule, deliberately: the entrance, with the SOSA Boond at Rs 799 or a reed diffuser from Rs 749 running continuously, and every bathroom with a reed - 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. Keep a physical off switch anybody in the house can reach without the app. Never scented: the kitchen at any time, the dining area, children's rooms, and covered terraces and balconies, which cannot hold fragrance. Everything is alcohol-free and made to IFRA-compliant standards.

The SOSA business gifting edit
Whatever your business gifts, the logic is the same: gift the milestone moment, set the per-unit band by customer value, keep the register gentle and crowd-safe, and brand the gesture with your card rather than your logo on the product. Every SOSA fragrance is alcohol-free and made in India, and a portion of every order supports girl-child education through Nanhi Kali - so every customer gift quietly gives twice.

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.
