Rarely, and when you do it should be something simpler than a commercial machine, because a house is not a small commercial space and the people in it did not brief you on their sense of smell.
Quick answers — read this first
Should a designer specify a scent machine in a client's home? Usually not a commercial machine. A reed diffuser from ₹749 needs no power, schedule or maintenance and leaves the choice with the household.
Why is a commercial machine wrong for a house? It is sized for a commercial volume, needs power in a specific place, needs somebody to own a setting, and imposes a continuous fragrance on people who live there rather than visit.
What is the ethical point? A household includes people who did not commission you, including children and anybody with a sensitivity. Specifying a continuous ambient fragrance makes a choice on their behalf that they cannot easily reverse.
The short answer
Short answer: Specify reeds, not a machine. And leave the choice with the household.

Commercial scenting goes wrong in a predictable order: somebody buys a machine to cover a smell that has a source, puts it where the socket is, runs it at full intensity because day one felt weak, and ends up with a room people comment on for the wrong reason. Source first, air volume second, unscented zones written down third, low intensity and a schedule fourth. This guide walks that sequence, with the real SOSA machine range at each size.
Should an interior designer specify commercial scenting in a client's home?
Rarely, and almost never a commercial machine. Why the product is wrong for a house. A commercial machine is sized for a commercial volume, needs a power point in a particular place, and needs somebody to own a setting and check it. In a house there is no facilities manager, and a setting nobody owns drifts upward or the machine simply stops being refilled and becomes an object on a shelf. It is also a great deal of capability for a domestic room, which will run at its lowest setting permanently if it runs at all. Why the decision is not entirely yours to make. A household is not a client. It contains people who did not commission you - a spouse who was not at the meetings, children, an elderly parent, staff who work there daily, and possibly somebody with a fragrance sensitivity nobody mentioned. Specifying a continuous ambient fragrance makes a choice on their behalf, in the one place where they cannot leave, and unlike a cushion it is not something they can quietly move to another room. That is a reason to specify something reversible rather than something installed.What to specify instead. A reed diffuser from ₹749 in a hall or living room: no power, no plug, no setting, no schedule, no owner. It runs down over six to ten weeks and the household decides whether to buy another, which puts the choice exactly where it belongs. It also looks like an object rather than an appliance, which matters in a room you have designed. Present it as an option rather than as part of the scheme, and say what it is, so nobody discovers a fragrance they did not agree to. When a machine is genuinely appropriate in a residence. A very large connected volume in a substantial house - a double-height hall or an open entertaining floor - where reeds will not hold. A client who has specifically asked for it, having understood that somebody will need to own the setting. Or a house that functions partly as a commercial or hospitality space. In those cases, a Vaayu at ₹11,999 on fragrance from ₹299, sized on air volume and handed over with a written setting, or an Aangan at ₹25,999 for a genuinely large volume. One thing to include in any handover. Which rooms are not scented, and how to switch it off. Bedrooms and children's rooms are better left clear, and anybody in the household should be able to stop it without a manual. In a materials showroom the stock is already the fragrance, and customers read it as evidence. Wood, leather and textile smells are information about what you sell, and a composed fragrance competing with them produces a mixture that reads as neither. Fragrance is an ambience decision and never a substitute for ventilation, cleaning or source control. A portion of every order supports girl-child education through Nanhi Kali.
One line: specify reeds and let the household decide whether to buy the second bottle.

Why a commercial machine misfits a home
The household includes people who were not in your meetings, which is the part of this question that is not about product selection.
Why this works
Specifying for a residence
Display floors are sized on air volume: the SOSA Vaayu at ₹11,999 for a contained area, Aangan at ₹25,999 for a large floor, Meenar at ₹38,500 for very large premises. Fragrance from ₹299.
A house has nobody to check a level or maintain a schedule, so a machine either drifts or stops being refilled. A reed diffuser needs nothing and ends on its own, which suits a domestic setting far better than commercial capability does.
Tip: Nobody in a house owns a setting.
02
The household did not brief you
And cannot leave the room
A spouse who missed the meetings, children, an elderly parent and daily staff all live with what you specify. A continuous ambient fragrance is a choice made on their behalf in the one place they cannot leave, which argues for something reversible.
Tip: They live there. They did not hire you.
03
Reversible beats installed
The bottle simply runs out
Reeds from ₹749 end after six to ten weeks and the household decides whether to continue. That puts the choice with the people who live with it, and it looks like an object rather than an appliance in a room you have designed.
Tip: Let it run out and let them choose.
The SOSA principle
A cushion can be moved to another room. A continuous ambient fragrance cannot.
Which is why the domestic answer should be reversible.

What to specify for a house
For a home, choose something quiet and unremarkable rather than something that expresses the scheme, because the people living there will meet it every day for years rather than admiring it once.

The SOSA commercial range
Whatever the space, the method is the same: find the source of any smell and fix it, draw the air volume rather than the floor plan, write down which zones stay unscented, then set a low intensity and a schedule. Every SOSA fragrance is alcohol-free and made in India, and a portion of every order supports girl-child education through Nanhi Kali. Here is the range by the size of space it is honestly built for.

Honest notes for materials-led showrooms: fragrance is an ambience decision only and is never a substitute for ventilation, cleaning or source control. Wood, leather and textiles carry their own scent, which customers use when assessing material quality, so display areas and sample libraries are generally specified as unscented and contained consultation rooms are scented instead. New-furniture off-gassing from adhesives, finishes and engineered board is resolved by ventilation and time rather than by fragrance. SOSA makes no claim that ambient scenting increases footfall, enquiries, conversion, retention, referrals, transaction value or customer spend, and no such claim should be made on the strength of this guide. Where association language is used it is descriptive of ordinary experience - people come to associate a place with how it feels - and is not a commercial performance claim. Ultrasonic diffusers and the machines run on the Hotel Collection fragrance; reed diffusers use their own alcohol-free reed oil, and the two are not interchangeable. The Hotel Collection scents are SOSA's own interpretations inspired by the world's finest hotels; SOSA is an independent Indian fragrance house and is not affiliated with, endorsed by or associated with any hotel brand. SOSA's fragrances are made in India; the scent machines are imported. Listed prices are store prices and are subject to change.

A note from Sonal
Furniture and interiors is the one retail category where the merchandise is already the fragrance, and customers are using it as evidence. Real wood, real leather, natural fibres - people smell the difference between those and their cheaper equivalents, whether or not they could tell you they are doing it. That is an advantage you have already paid for in your buying, and covering it with an ambient scent throws it away.
So my advice for an Ahmedabad furniture or modular kitchen showroom is almost always the same: leave the display floor to the materials and scent the rooms where people sit and decide. A consultation area, a design lounge, a reception - contained spaces, away from the bulk of the stock, where a low dry woody register sits alongside the material character instead of arguing with it.
And the new-stock problem, which every showroom in this category has: furniture off-gasses for weeks from adhesives, finishes and boards, and in a sealed hard-air-conditioned Ahmedabad showroom it accumulates. That is ventilation, not fragrance - and fragrance over it is masking, which customers evaluating material quality are exactly the people who notice. WhatsApp +91 96192 18531.
