Is power a real constraint when planning scent machine placement? No. A SOSA Vaayu draws 5W, a trivial electrical load, so this is a joinery and services question, not a power one. The real decisions are where the unit sits, whether it needs a discreet point on the electrical drawing, and where the HVAC return is, since that decides what can later be zoned together.
What happens if machine placement is left until after the interiors are finished? It usually means a compromise: a visible unit sitting on a console because there was nowhere left to recess it, or a trailing cable across a finished floor because no point was left. Planning placement before the ceiling closes and the joinery is fitted avoids both, the same way a light fitting or speaker location would be planned early.

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, measuring 165 x 80.5 x 215mm and weighing 0.9kg, drawing DC 12V/1A, 5W, with a 400ml refillable tank lasting up to about 75 days, a Bluetooth app with 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, with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, connecting to the building's HVAC or standalone wall-mounted. 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. Prices and availability are subject to change - see the live product pages.
The question every designer eventually asks is timing, not choice of machine - and the honest answer is that placement, power and mount type belong on the drawing, not on a punch list after the sofas arrive, because a decision made after the joinery is fitted is a decision made badly.
Quick answers — read this first
When should an interior designer plan machine placement, before or after the interiors are completed? Before. Placement, a discreet power point, and whether a unit is freestanding, wall-mounted or HVAC-mounted are design-stage decisions, settled before the false ceiling closes and the joinery is fitted. A SOSA Vaayu (₹11,999) needs a joinery recess or wall position decided early; retrofitting after handover usually means a visible machine or a trailing cable.Is power a real constraint when planning scent machine placement?

The short answer
Short answer: before the interiors are completed - placement, a discreet power point and the mount type (freestanding, wall or HVAC) are design-stage decisions; 5W is a trivial load, so this is a joinery and services question, and retrofitting after handover means a visible machine or a trailing cable.
The pick: decide the SOSA Vaayu's (₹11,999) recess or wall position, and the SOSA Angaan's (₹25,999) HVAC tie-in, before the false ceiling closes and the joinery is fitted - not after.
Next step: send us the electrical and HVAC drawings early and we will mark the placement before the ceiling closes - book a free scenting plan.

Straight answer
Should scent machine placement be decided during design or after the interiors are finished?
During design, without exception. Placement, a discreet power point, and whether a unit is freestanding, wall-mounted or HVAC-connected are all design-stage decisions, exactly like a light fitting, a speaker location or an AV point - they need to be settled before the false ceiling closes and the joinery is fitted, not afterwards. Retrofitting once a room is finished forces one of two compromises: a visible machine placed wherever a flat surface happens to be free, or a trailing cable across a finished floor because nobody left a point for it. 5W is a trivial electrical load, so this was never really a power question - it is a joinery and services question, and treating it as one from the start avoids the retrofit entirely. The other detail worth deciding early is where the HVAC return sits, because that single location decides what rooms can honestly be zoned together on an SOSA Angaan (₹25,999) later, and what cannot - two rooms on the same return are a candidate for one machine; two rooms on separate returns are not, whatever the floor plan implies. A SOSA Vaayu (₹11,999) planned into a joinery recess at the drawing stage looks planned rather than added, which is the whole point. A free scenting plan reviewed against your drawings early is the simplest way to get this right the first time, and a portion of every order supports girl-child education through Nanhi Kali.
Before, always. Placement, power point and mount type are joinery and services decisions - 5W is a trivial load, not the constraint.
Bring the SOSA Vaayu (₹11,999) into the drawing stage, not the punch list. A joinery recess, a discreet power point and the mount type - freestanding, wall or HVAC - all need deciding before the ceiling closes. The Angaan follows the same rule for an HVAC-tied zone.

The shortlist
Both machines are design-stage decisions, not retrofit items.
The two machines a designer plans in at drawing stage
Two machines, both decided at drawing stage. The choice between them depends on whether a room is planned as its own zone or tied into a shared HVAC return.
A room-level joinery recess or wall position
SOSA Vaayu
Waterless cold-air nebuliser rated to 1000m³ - about 2,000-3,000 sq ft. 165 x 80.5 x 215mm, small enough to sit in a recess decided at drawing stage.
From ₹11,999
A discreet power point on the electrical drawing
SOSA Vaayu (placement)
5W is a trivial load - the point itself just needs to exist in the right place before the wall closes, which is a five-minute addition to the electrical drawing at this stage and a visible cable afterwards.
From ₹11,999
An HVAC-tied zone, decided by the return location
SOSA Angaan
HVAC nebulising diffuser rated to 3,000m³, 800ml reservoir, metal body, programmable schedules, under 42dB. Tied to wherever the HVAC return sits, which is exactly why that location needs deciding early.
From ₹25,999
Why machine placement is a design-stage decision, not a retrofit
Three decisions belong on the drawing, and all three are cheap now and expensive later.
1
Placement and mount type
Freestanding, wall-mounted or HVAC-mounted - decide before the ceiling closes
A machine decided after the room is finished has to go wherever a flat surface and a socket already exist, which is rarely the right spot. Decided at drawing stage, it can sit in a joinery recess, behind a returned wall, or mounted directly on the HVAC - all options that disappear once the false ceiling and joinery are in.
Tip: the same rule as a light fitting or a speaker: decide the position before the room closes around it.
The Vaayu's small footprint - 165 x 80.5 x 215mm - fits almost any recess decided early.

2
5W is a joinery question, not a power question
The load is trivial - the placement is not
It is tempting to treat this as an electrical sizing problem, and it never is. 5W does not move the needle on a home's electrical plan. What actually needs deciding is where the point sits relative to the final joinery, so a cable is never visible and never trailing across a finished floor.
A Vaayu on DC 12V/1A, 5W draws less than most phone chargers - power was never the constraint.
See SOSA Vaayu →
3
The HVAC return decides what can be zoned
Specify its location before deciding the fragrance zones
Two rooms sharing one HVAC return are honest candidates for one machine later; two rooms on separate returns are not, whatever the floor plan suggests. Knowing where the return sits at drawing stage lets the designer plan realistic fragrance zones instead of guessing after the ducting is closed in.
Tip: mark the return location on the services drawing before finalising the zoning plan.
The Angaan uses that exact return to carry scent on the home's existing airflow, once it is known.
See SOSA Angaan →
The SOSA principle
A retrofitted machine is never wrong because of the hardware. It is wrong because the room was already finished when someone finally asked where it should go.
The question is never whether the machine fits. It is whether the drawing left it anywhere to fit.

Once placement is decided, the next honest question is whether it can be hidden entirely rather than just tidied - our companion piece on whether scenting can be hidden within the design covers the specific joinery options, and whether a designer can offer scenting as part of a final sensory handover covers where this fits at project close. The Ludhiana guide to buying a commercial scent machine covers the wider decision.

5W is a trivial load. The real decision is where the point sits before the wall closes around it.

A quick word on sequencing: bring the placement conversation in alongside electrical and HVAC drawings, not after them. One honest limit - this is a joinery and services decision, never a claim that early planning changes how a project is received. The quickest way to get it onto the drawing is a free scenting plan.

A note from Sonal
Interior designers ask me this in almost every project brief now: does the scent machine get decided at the drawing stage, or is it something we add once the sofas are in? The honest answer only works one way.
Plan it before the interiors are completed, not after. Placement, a discreet power point, and whether a unit is freestanding, wall-mounted or connected to the HVAC are all design-stage decisions - they need to be settled before the false ceiling closes and the joinery is fitted, the same way a light fitting or a speaker location is. Retrofitting after handover almost always means one of two compromises: a visible machine sitting on a console because there was nowhere else left, or a trailing cable across a finished floor because nobody thought to leave a point. 5W is a trivial electrical load - this is a joinery and services question, not a power one, and it should never be the reason a decision gets delayed. The one drawing detail worth specifying early is where the HVAC return sits, because that single point decides what can honestly be zoned together later and what cannot.
None of this changes what SOSA can honestly claim: a SOSA Vaayu (₹11,999) planned into a joinery recess or an SOSA Angaan (₹25,999) planned onto the HVAC does not sell the project or change what a client decides - it simply means the machine looks planned rather than added. Fragrance still works alongside ventilation and cleaning, never instead of it. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
When should an interior designer plan machine placement, before or after the interiors are completed?
Before. Placement, a discreet power point and the mount type - freestanding, wall or HVAC - are design-stage decisions, settled before the false ceiling closes and the joinery is fitted. Retrofitting after handover usually means a visible machine or a trailing cable.
Is 5W a real constraint when planning where a scent machine goes?
No. 5W is a trivial electrical load, so this is a joinery and services question, not a power one. What matters is where the point sits relative to the finished joinery, not whether the circuit can carry it.
Why does the HVAC return location matter for placement planning?
Because it decides what rooms can honestly be zoned together on a shared machine later. Two rooms on one return are a genuine candidate for one Angaan; two rooms on separate returns are not, regardless of how the floor plan looks.
What happens if placement is decided after the interiors are finished?
Usually a compromise: a visible unit placed wherever a flat surface and a socket already exist, or a trailing cable across a finished floor because no point was left. Deciding placement at drawing stage avoids both.
Should placement be shown on the electrical or the HVAC drawing?
Both, depending on the machine. A Vaayu's power point belongs on the electrical drawing; an Angaan's tie-in belongs on the HVAC drawing at the marked return location. Either way, it should be decided alongside the other services, not after them.
