How strong should a show apartment smell? Noticeable at the door and forgotten by the second room. That is why the sample flat runs a step below the sales office on the SOSA Vaayu (₹11,999), which has adjustable intensity for exactly this reason. A flat that smells strongly perfumed reads as staged; the same fragrance, quieter, reads as a home that someone lives in.
Does a larger sample flat need a higher intensity setting? Only slightly, and often not at all. One SOSA Vaayu (₹11,999) covers 1000m³, about 2,000-3,000 sq ft, so a four-bedroom flat is still one machine. Start every flat at the same step as the rest of the portfolio, check it at the door, and step up only if the far bedrooms read as empty. Write the change into the register so it is a documented exception rather than a local habit.

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 onboard button control, 1h/4h/8h/24h timers, adjustable intensity, operation under 38dB, freestanding or wall and HVAC mounting, auto-stop and key-lock for public spaces, 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, connecting to the building's HVAC or running 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.

Intensity is the setting everyone adjusts by feel, which is why a buyer visiting three of your projects meets three different homes. The fix is one rule, one reference point and one honest place to stand while judging it. Here is how to make a show flat repeatable across a portfolio.
Quick answers — read this first
How do I standardise fragrance intensity across several sample flats? Set one rule and write it down: every show apartment runs one SOSA Vaayu (₹11,999) at one intensity step below the sales office standard, on the same fragrance and the same timer block. Judge the result standing at the front door 30 to 45 minutes after the machine starts, not standing beside the machine. Record any exception, such as a duplex with separate air-conditioning upstairs, in the site register.How strong should a show apartment smell? Noticeable at the door and forgotten by the second room.

The short answer
Short answer: run one SOSA Vaayu (₹11,999) per sample flat at one intensity step below the sales office standard, on the same fragrance and timer block, judge it from the front door 30 to 45 minutes after start rather than beside the machine, and record any exception in the site register so twelve flats stay repeatable.
The pick: the SOSA Vaayu (₹11,999) in every show apartment, one step softer than the sales office, stepping up to the SOSA Angaan (₹25,999) only for a genuinely double-height volume such as a large duplex atrium.

Straight answer
How strong should the fragrance be in a sample flat, and how do I repeat it everywhere?
Start from the rule rather than the room: every sample flat runs one intensity step below the sales office, on the same fragrance and the same timer block. One SOSA Vaayu (₹11,999) covers the whole flat - it is rated to 1000m³, roughly 2,000-3,000 sq ft, and a show apartment is one connected volume rather than a set of rooms - so intensity, not machine count, is the variable you are standardising. Then fix how you judge it. Walk out, come back, and assess from the front door about 30 to 45 minutes after the machine has started. Standing next to a running machine tells you nothing except that machines smell. At the door you want the fragrance to register once and then disappear as you walk through; if it is still announcing itself in the third room, step down. Two adjustments are legitimate and both should be written into the site register rather than left to memory: a flat with unusually high ventilation or a permanently open balcony door may need the sales office step after all, and a duplex with separately air-conditioned upper level is two machines rather than a higher setting. There is a running-cost consequence too, and it is in your favour: at a softer step the 400ml tank runs closer to the 75-day upper end, so flats generally need topping up less often than sales offices, and that difference will show up in your refill log. Where a duplex atrium is genuinely double height, an SOSA Angaan (₹25,999) on the HVAC is the honest answer. A free multi-site scenting plan will set the standard step with you, and a portion of every order supports girl-child education through Nanhi Kali.

The flat standard
One machine, one step down, one place to stand while you judge it
The machine in every sample flat
One machine appears in every sample flat you own, and it is the same one that runs the sales office - just a step quieter. The second machine only appears where a duplex volume is genuinely double height.
One per show apartment, whatever the bedroom count
SOSA Vaayu
Adjustable intensity is the feature that matters here: same fragrance as the sales office, one step lower. Rated to 1000m³, about 2,000-3,000 sq ft, 400ml tank lasting up to about 75 days, under 38dB, waterless with no residue on finishes.
From ₹11,999
The duplex exception - a second unit upstairs
SOSA Vaayu (second unit)
Where a show duplex has its own air-conditioning on the upper level, that level is a separate volume and needs its own machine at the same step, rather than the ground floor unit being turned up to compensate.
From ₹11,999
Only for a genuinely double-height volume
SOSA Angaan
Rated to 3,000m³, about 8,000-10,000 sq ft, with an 800ml reservoir, metal body, programmable schedules and under 42dB. Relevant for a duplex atrium or an apartment-style experience centre, not for an ordinary flat.
From ₹25,999
How to set an intensity you can repeat in twelve flats
Repeatable intensity comes down to three things: a reference point, a place to stand, and a register that records the exceptions instead of hiding them.
1
Set the reference, not the flat
One step below the sales office, everywhere
Do not tune each flat from scratch. Fix the sales office step first as the portfolio reference, then define the sample flat as exactly one step below it. That way a single decision cascades to every show apartment you own, and when the reference changes, the flats change with it automatically. It also makes the walk between the two spaces coherent: a buyer who crosses from the sales office to the flat should feel the same fragrance getting quieter, which reads as moving from a public space into a home.
Tip: define the flat setting relative to the office setting, never as a number on its own.
Adjustable intensity on the Vaayu is what makes a one-step relationship possible across twelve flats.

2
Judge it from the door
Thirty to forty-five minutes after start, from where a buyer stands
Nose blindness is real and it sets in within a couple of minutes, which is why the person adjusting the machine is the worst possible judge of the result. Start the machine, leave the flat, come back after 30 to 45 minutes and assess from the threshold. The target is simple: you notice it once as you enter, and by the second room you have stopped thinking about it. If it is still present in your attention in the third room, it is a step too high, whatever it felt like from beside the machine.
In a genuinely double-height duplex atrium the answer is not more intensity but an Angaan on the HVAC, rated to 3,000m³.
See SOSA Angaan →
3
Record the exceptions
A written exception is a standard, an unwritten one is drift
Some flats really are different. A unit with a permanently open balcony door, a high-floor flat with strong cross-ventilation, or a show duplex with its own air handling upstairs will not match at the standard step. That is fine, as long as it goes in the site register with a reason. The failure mode is the undocumented change, where someone steps a flat up in June, nobody records it, and by the following year three flats are running hot and the oil consumption at those sites is quietly double the rest.
Tip: an exception without a written reason is just drift with better manners.
A softer step also stretches the Vaayu's 400ml tank closer to the 75-day upper end, so the register and the refill log should agree with each other.

The SOSA principle
A show flat that announces its fragrance has told the buyer it is a set. The same scent a step quieter tells them it is a home, and the only difference between the two is one number on a machine.
Judge it from the doorway, never from beside the machine. Your nose has already forgiven the machine.
The intensity step, flat type by flat type
The step, flat type by flat type. Note that the machine count barely moves and the intensity barely moves either - which is the point of a standard.

This page deals only with intensity in the flats. The sales office reference it hangs off is set in standardising scent machine settings across multiple sales offices, and because a softer step changes how fast a tank empties, the consequences land in planning monthly scent machine refills across multiple project sites. Keep the fragrance itself out of this decision entirely - it should already be fixed at portfolio level. If you are working on a single project rather than a portfolio, the sales gallery scenting plan is the place to start.

Why waterless matters in a flat
No damp near wardrobes, no residue on veneer, nothing for housekeeping to wipe
The SOSA sample flat intensity specification
One machine covers every sample flat in the portfolio, and the only variable you standardise is the intensity step. The Angaan appears only where a duplex volume is genuinely double height. Both machines are waterless, which matters more in a flat than anywhere: no damp near wardrobes, no residue on veneer or fabric. Both are made in India, and a portion of every order supports girl-child education through Nanhi Kali.

A quick word on judging intensity: do it from the front door, 30 to 45 minutes after the machine starts, and never from beside the machine. If the fragrance is still in your attention by the third room, step it down. One honest note - fragrance works alongside ventilation and cleaning and cannot cover fresh paint, adhesive or damp in a newly finished flat, which need curing and airing first. We will set the standard step with you on a free multi-site scenting plan.

A note from Sonal
The most common mistake in a show flat is not the fragrance. It is the volume. Somebody sets it while standing next to the machine, decides it is barely there, turns it up, and by the time a family walks in the flat smells like a spa reception. A home does not smell like that, and buyers know it even if they never put it into words.
So we set intensity by relationship, not by feel. The sales office gets the portfolio reference step, and every sample flat runs one step below it on the same fragrance. The Vaayu has adjustable intensity precisely so that relationship is easy to hold across twelve flats, and one machine covers a whole apartment because a flat is one body of air, not four bedrooms. Only a genuinely double-height duplex atrium changes the answer, and then it is an Angaan on the HVAC.
The honest note, which belongs on this page more than most: a beautifully scented show flat does not sell a flat, and I make no claim that fragrance influences a purchase decision. What a consistent, quiet setting does is stop the flat feeling like a set, and keep the third project feeling as considered as the first. Scent works alongside ventilation and cleaning, never instead of them, and it cannot cover fresh paint, adhesive or damp in a recently finished flat. SOSA is independent and not affiliated with any hotel, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
How do I keep fragrance intensity consistent across sample flats at different projects?
Define the flat setting relative to the sales office rather than on its own: every show apartment runs one SOSA Vaayu (Rs 11,999) at one intensity step below the office standard, on the same fragrance and the same timer block. Judge the result from the front door 30 to 45 minutes after the machine starts, and record any exception in the site register with the reason.
How strong should a show apartment smell?
Noticeable once at the door, then forgotten by the second room. If the fragrance is still occupying your attention in the third room, it is a step too high. A flat that smells strongly perfumed reads as staged, while the same scent quieter reads as lived in, which is the impression a show flat is meant to give.
Does a four-bedroom sample flat need a stronger setting than a two-bedroom?
Rarely. One SOSA Vaayu covers 1000 cubic metres, about 2,000 to 3,000 sq ft, so the flat is still one machine. Start at the portfolio standard step, then check the far bedrooms from the doorway. If they read as empty, step up once and write the change into the register so it is a documented exception rather than a local habit.
Does a lower intensity make the refill last longer?
Yes. The 400ml tank is quoted as lasting up to about 75 days, and that upper figure assumes moderate intensity and typical run hours. Running a flat a step below the sales office pushes it towards the top of that range, so sample flats generally need topping up less often than the offices. Your refill log will show the difference within two rounds.
Should the sample flat use a different fragrance from the sales office?
No. Same fragrance, lower step. Two fragrances across one site doubles your stock lines, invites the wrong bottle into the wrong machine and breaks the sense that the office and the home belong to the same project. Fragrance is a portfolio-level decision; intensity is the only thing that changes between the two spaces.
