Does specifying a scent machine mean designing a new system? No. It is four small additions to drawings the interior designer is already producing - a mount note on the RCP, a power point in the electrical schedule, a clearance check against the HVAC layout, and a choice between a wall-mounted Vaayu or a ducted Angaan. There is no separate control system to design because neither machine integrates with one.
Who actually picks the machine and the position - the designer or the client? The designer specifies the position and mount, working from the room's layout and HVAC drawings; the fragrance and exact schedule are usually set later with the homeowner, closer to handover. Getting the placement right at design stage is what keeps that later choice simple.

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 (about 2,000-3,000 sq ft), with a 400ml refillable tank lasting up to about 75 days depending on intensity and run hours, a Bluetooth app and onboard buttons with 1h/4h/8h/24h timers and adjustable intensity, operation under 38dB, a DC 12V/1A power draw of about 5W, dimensions of 165 x 80.5 x 215mm at 0.9kg, freestanding or wall/HVAC mounting, auto-stop, key-lock, and CE, RoHS and SGS certification. The SOSA Angaan (₹25,999) is an HVAC nebulising diffuser rated to 3,000m³ (about 8,000-10,000 sq ft) with an 800ml reservoir, metal body, programmable schedules and operation under 42dB, connecting to the building's HVAC or running standalone wall-mounted. Neither machine integrates with a smart-home protocol, a control system, sensors or voice assistants - both are scheduled standalone machines controlled from an on-site Bluetooth app. 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.
Yes - and the reason interior designers hesitate is that 'specifying a scent machine' sounds like designing a new system, when it is actually four small notes on drawings already being produced. Here is exactly what those four notes are.
Quick answers — read this first
Should interior designers specify scent machines during the design stage? Yes. Specifying it means marking a mount position on the reflected ceiling plan, adding a power point to the electrical schedule, and confirming clearance from the nearest supply vent - the same kind of notes already made for lighting and AV.

Straight answer
What does it actually mean for an interior designer to specify a scent machine?
It means four things, all of them additions to drawings the designer is already producing rather than a new discipline. First, a mount position for the SOSA Vaayu (₹11,999) or SOSA Angaan (₹25,999) marked on the reflected ceiling plan, alongside the downlights and AV points. Second, a power point added to the electrical schedule the electrician is already working from - a trivial 5W addition. Third, a clearance check against the HVAC layout, so the machine never sits in the direct throw of a supply vent. Fourth, a choice between wall-mounted or HVAC-mounted: the Vaayu can do either, and the Angaan is built to connect to the building's air handling. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. None of this requires the designer to become a fragrance specialist - the scent itself and the exact daily schedule are usually finalised later, closer to handover, once the homeowner is involved. What has to happen at design stage is the placement, because that is the part that becomes expensive to change once the ceiling closes. A conversation about your project is the fastest way to confirm the notes before they go on the drawing. A portion of every order supports girl-child education through Nanhi Kali.
Specifying it means four notes: a mount on the RCP, a power point in the electrical schedule, a clearance check against the HVAC layout, and a wall or HVAC mount choice. All four belong on drawings already in progress.
Specifying the SOSA Vaayu means one mount note on the RCP and one power point in the electrical schedule - a 5W addition, waterless, under 38dB. Nothing about it requires a new system drawing. ₹11,999.

The specification shortlist
Two machines, four notes, both already fit inside drawings in progress
The two machines that go on the specification
Two machines, both small enough that specifying them is a note, not a redesign. Both pictures link to the product page so your team can check the specification before it goes on the drawing.
One zone, marked on the RCP
SOSA Vaayu
Waterless cold-air nebuliser, 1000m³ coverage, 5W power draw. Under 38dB, freestanding or wall/HVAC mount. Specifying it is one mount note and one power point.
From ₹11,999
A home already on central HVAC
SOSA Angaan
HVAC nebulising diffuser, 3,000m³ coverage, 800ml reservoir, metal body, programmable schedules, under 42dB. Specifying it is a ducted note against the existing HVAC drawing.
From ₹25,999
What 'specifying' a scent machine actually involves
Three things distinguish a real specification from a vague intention to 'add scenting later' - all three are small enough to fit inside drawings already being produced.
1
A mount position on the RCP
The same drawing that already carries downlights and AV points
The reflected ceiling plan is where lighting, AV and HVAC diffuser positions already live. A scent machine's mount - wall-mounted or HVAC-mounted - belongs on that same drawing, at the same review, rather than as a verbal instruction given on site later. This is the single note that most protects against a compromised position after the ceiling closes.
Tip: one symbol on the RCP is the whole specification for position.
The Vaayu can be wall-mounted or HVAC-mounted, so the RCP note is a choice between two straightforward options, not an open design question.
See SOSA Vaayu →
2
A power point in the electrical schedule
A trivial 5W addition to a schedule already being written
The electrician working from the electrical schedule needs one more point added to it - nothing about the load requires special provision, since 5W is negligible next to lighting or HVAC circuits. What matters is that the point's location matches the mount position from the RCP, so no cable is ever visible in the finished room.
The Angaan connects inside the plant room when a home already runs on central HVAC, which can remove the need for a separate visible power point altogether.
See SOSA Angaan →
3
A clearance check against the HVAC layout
Never in the direct path of a supply vent
A scent machine placed directly in a supply vent's throw gets its output blown away before it settles into the room, and one placed with no air movement at all diffuses unevenly. The clearance check is a five-minute cross-reference against the HVAC drawing, confirming the mount sits near moving air without being in its direct line.
Tip: check it against the HVAC drawing, not by eye on site.
The Vaayu's compact size (165 x 80.5 x 215mm) makes it easy to slot into a niche once the clearance check confirms the right spot.
See SOSA Vaayu →
The SOSA principle
Interior designers already specify a dozen small fittings this way - a mount note here, a power point there. Scenting is not a different kind of decision. It is the same kind, made on time.
The hesitation is usually about scope, not difficulty. Once the scope is four notes, the decision gets much easier to make on schedule.
One Vaayu per zone, one Angaan for a home already on central HVAC
The machine choice mirrors the mount choice: a wall-mounted Vaayu for most zones, a ducted Angaan when the home already runs on central HVAC throughout.

What goes on the drawing
A mount note, a power point, and a clearance check - nothing more
The SOSA interior-design specification
Both machines are specified the same way lighting and AV are: a mount note, a power point, a clearance check. The Vaayu suits most zones at a trivial 5W; the Angaan connects inside the plant room for a home already on central HVAC. Both are waterless and made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A note from Sonal
The interior designers who specify this best are the ones who stop treating it as a special category and just add it to the list of things already being marked on the RCP for the week. It takes the same five minutes as a downlight symbol, and it gets the same result: a decision made on time instead of argued about on site.
What I tell every design team is that specifying the Vaayu or Angaan is four things - a mount position, a power point, a clearance check against the HVAC layout, and a choice of wall or HVAC mount. Neither machine speaks to a control system. There is no Control4, Crestron, Lutron, KNX or Matter driver, no wifi, no cloud account, and no voice-assistant skill. Vaayu is operated from its own on-site Bluetooth app with 1h/4h/8h/24h timers; Angaan runs its own programmable schedule. Both are scheduled and standalone, which is exactly what makes them simple to specify and simple for a homeowner to run once the project is handed over. None of that is a new discipline. It is the same coordination work already being done for a dozen other fittings, applied to one more.
The fragrance itself and the day-to-day schedule are the part I leave for later, closer to handover, once the homeowner is in the room. What has to happen now is the placement, because that is the part that gets expensive to change. Everything is made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Should interior designers specify scent machines at the design stage?
Yes. Specifying it means marking a mount position on the reflected ceiling plan, adding a power point to the electrical schedule, and checking clearance against the HVAC layout - the same kind of note already made for lighting and AV. The SOSA Vaayu (Rs 11,999) suits most zones; the SOSA Angaan (Rs 25,999) suits a home already on central HVAC.
Does specifying a scent machine mean designing a whole new system?
No. It is four additions to drawings already being produced: a mount note on the RCP, a power point in the electrical schedule, a clearance check, and a choice between wall or HVAC mounting. Neither machine connects to a control system, so there is no protocol to design in.
Who chooses the actual fragrance - the interior designer or the homeowner?
Usually the homeowner, closer to handover, once the placement has already been decided. The interior designer's job is the position and the power point; the scent and daily schedule are a later, lighter decision.
What is the electrical impact of specifying a scent machine?
Very small. The SOSA Vaayu draws about 5W on a DC 12V/1A adapter, a trivial addition to an electrical schedule already carrying lighting and AV circuits. The point worth spending time on is the power point's location, not its capacity.
Does the scent machine need to be shown on the HVAC drawing?
Only for a clearance check - confirming it will not sit in the direct throw of a supply vent - and, for the SOSA Angaan, to show its connection into the plant room. The SOSA Vaayu can be wall-mounted independently of the HVAC drawing entirely.
