Does a scent machine need a lot of electrical infrastructure planned in? No. The SOSA Vaayu draws 5W, a trivial electrical load compared to lighting or HVAC. The real design-stage decision is placement and a discreet power point, not electrical capacity - it is a joinery and layout question, not a power one.
Why is it better to specify scenting during design rather than after handover? Because retrofitting a scent machine into a finished interior almost always means a visible unit or a trailing cable, exactly what a considered interior cannot carry. Deciding the mount and power point before the false ceiling closes lets the machine disappear into the finish instead.

Facts verified 24 August 2026 against the live SOSA product pages: the SOSA Vaayu (₹11,999) is a waterless cold-air nebuliser rated to 1000m³, described by the manufacturer as approximately 2,000-3,000 sq ft, with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, Bluetooth app and button control, 1h/4h/8h/24h timers, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³, roughly 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, and also runs standalone wall-mounted or lay-flat. Scent enhances the ambience and perceived quality of a space; it works alongside proper ventilation and cleaning and is not a substitute for either, and SOSA makes no claim that fragrance alone influences a purchase decision. The hotel-inspired scents are SOSA's own original interpretations; SOSA is an independent brand and is not affiliated with, or endorsed by, any hotel named for reference. Coverage, fragrance usage and running cost depend on the space, settings and hours of use, and are confirmed on a consultation.

The short answer
Short answer: yes - placement, a discreet power point and a wall or HVAC mount for a SOSA Vaayu (₹11,999) should be decided before the false ceiling and joinery close, since 5W is a trivial electrical load and this is genuinely a placement question, not a power one.
The pick: a SOSA Vaayu (₹11,999) specified into the drawings with its mount and power point, stepping up to a SOSA Angaan (₹25,999) on the HVAC for a larger floor.
Next step: send us your interior drawings and we will mark up placement and power before the joinery is fitted - book a free scenting plan.

Straight answer
Can interior designers specify a commercial scent machine during the planning stage rather than adding one after handover?
Yes, and doing so is genuinely better practice than retrofitting. Three things need deciding before the false ceiling closes and the joinery is fitted: placement - where a SOSA Vaayu (₹11,999) sits relative to the room's airflow, never in the direct path of a supply vent or fan, which would disperse the fragrance unevenly; a discreet power point planned into the electrical layout at that location, rather than an extension cable run afterwards; and the mount itself - the Vaayu can be freestanding, wall mounted or HVAC mounted, and choosing wall or HVAC mount at the design stage lets it disappear into the finish rather than sit visibly on a console or shelf. Retrofitting any of this after handover almost always means one of two compromises: a visible machine sitting somewhere it was not designed to be, or a trailing cable across a finished floor - neither of which a considered interior can carry. The good news for the electrical planning specifically is that 5W is a trivial load, nowhere near what lighting or HVAC draws, so this is genuinely a placement and joinery decision, not a power one, and it should sit with whoever already owns the room's air handling - typically the HVAC consultant working with the interior designer. A larger open floor on shared HVAC is a case for a SOSA Angaan (₹25,999) specified the same way. A free scenting plan can mark up placement and power directly on your drawings, and a portion of every order supports girl-child education through Nanhi Kali.
Placement, a power point and the mount are design-stage decisions. 5W is trivial - this is joinery, not power. Retrofitting means a visible machine or a trailing cable.
For most zones the machine to specify is one SOSA Vaayu - waterless, under 38dB, rated to 1000m³ (about 2,000-3,000 sq ft), 5W, freestanding, wall or HVAC mounted. Mark its position and power point on the drawings before the false ceiling closes.

What actually needs deciding before the false ceiling closes
Three things belong in the drawings, not in a post-handover retrofit: where the machine sits relative to airflow, where its power comes from, and how it is mounted.
1
Placement, relative to airflow
Never in the direct path of a supply vent or fan
A scent machine placed directly in a supply vent's airflow disperses fragrance unevenly and burns through refill faster than necessary. The right position is decided by whoever is already planning the room's air handling, and it needs to happen before ductwork and diffusers are finalised, not worked around afterwards.
Tip: the HVAC consultant should own this decision, with the designer.
The Vaayu can be freestanding, wall mounted or HVAC mounted, which gives real flexibility once placement is planned early.
See SOSA Vaayu →
2
A discreet power point, planned into the layout
5W is trivial - this is about where the socket is, not its capacity
The SOSA Vaayu draws 5W, a fraction of what lighting or HVAC needs, so electrical capacity is a non-issue. What matters is a socket in the right place, planned into the electrical layout at the design stage, rather than an extension cable trailing across a finished floor after handover.
A power point specified early means the Vaayu connects invisibly, exactly where it needs to sit.
See SOSA Vaayu →
3
The mount, decided before the ceiling closes
Wall or HVAC mount, chosen at the design stage
Once a false ceiling is closed and joinery is fitted, changing a machine's mount means cutting into a finished surface. Deciding wall or HVAC mount during planning lets the machine sit flush with the finish, exactly as intended, rather than as a visible retrofit.
Tip: retrofitting means a visible unit or a trailing cable - neither belongs in a finished interior.
For a larger floor, the Angaan's HVAC connection is itself a design-stage decision, tied to the ductwork layout.

The SOSA principle
5W is a trivial electrical load. The real decision an interior designer is making is about joinery and placement - where the machine sits relative to airflow, and how invisibly it sits in the finish.
Specify it early and it disappears into the room. Retrofit it later and it sits on top of the room instead.
Vaayu or Angaan - specified before the joinery, not after
Once placement, power and mount are settled at the design stage, the machine choice is straightforward. Here is the whole table.

Whoever owns the room's air handling should own this decision - usually the HVAC consultant working with the interior designer, since the automation integrator, if there is one, is only coordinating services that are already being planned. If the space in question is a smart-home experience centre specifically, our guide on automated scenting in a demonstration covers what the machine can and cannot be asked to do once it is specified in. And if the interior is still mid fit-out, read when it is appropriate to introduce fragrance before the machine is switched on.

5W is a trivial load. The real design decision is where the machine sits and how it disappears into the finish - and that has to be decided before the ceiling closes.

The SOSA design-stage specification
Two machines, one decision. The Vaayu handles a normal design-stage specification on its own; the Angaan takes over only when a single volume is genuinely too large or too tall for one Vaayu to do honestly. Both are waterless, so there is no damp and no residue on materials, samples or finishes, and both are made in India. A portion of every order supports girl-child education through Nanhi Kali.

A quick word on choosing: the step up from Vaayu to Angaan is about air volume, never about budget or ambition. Specify placement, power point and mount at the drawing stage for either machine - retrofitting after handover means a visible unit or a trailing cable. One honest note - fragrance works alongside ventilation and cleaning, and it is not a substitute for either. The quickest way to get the specification right is a free scenting plan.

A note from Sonal
Most of the calls I get about scent machines after a project is finished are the same call: a beautiful, completed interior, and now an awkward conversation about where to put a diffuser that nobody planned for. It is always solvable, but it is never as good as it would have been if someone had asked the question three months earlier, while the drawings were still open.
The decisions that belong at that earlier stage are simple: where the SOSA Vaayu sits relative to the room's airflow, never in the direct path of a supply vent; a discreet power point planned into the electrical layout at that spot; and whether it is wall mounted or HVAC mounted, decided before the false ceiling closes. A larger floor on shared HVAC gets the same treatment with a SOSA Angaan, its connection planned alongside the ductwork.
The one number worth remembering is 5W - genuinely trivial next to lighting or HVAC, which is exactly why this is a placement and joinery conversation, not an electrical capacity one. Whoever already owns the air handling, usually the HVAC consultant working with the designer, should own this decision too. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Can interior designers specify a commercial scent machine during the planning stage?
Yes, and it is genuinely better than adding one after handover. Placement relative to airflow, a discreet power point, and the wall or HVAC mount for a SOSA Vaayu (Rs 11,999) should all be decided before the false ceiling closes and the joinery is fitted.
Does a scent machine require significant electrical planning?
No. The SOSA Vaayu draws 5W, a trivial load compared with lighting or HVAC. The real design-stage question is where the power point and the machine itself sit, not whether the electrical system can support it.
What happens if a scent machine is added after an interior is already finished?
It usually means a compromise: a visible unit sitting somewhere it was not designed to be, or a trailing cable across a finished floor. Specifying the mount and power point at the design stage avoids both.
Where should a scent machine never be placed?
Never in the direct path of a supply vent or fan - it disperses the fragrance unevenly and wastes refill oil faster than necessary. Placement should be decided alongside the room's air handling plan.
Who should decide where a scent machine goes in a project?
Whoever already owns the room's air handling, typically the HVAC consultant working with the interior designer. An automation integrator, where one is involved, is usually only coordinating services that are already being planned by those two.
