What’s the ongoing cost? Refills from ₹999, plus a signature scent from ₹299 — roughly one refill per zone a month.
Is it dear compared with candles? No — a diffuser sips a refill over weeks where luxury candles burn away in an evening.
2. Or whole-floor HVAC. An Aangan at ₹25,999 (8,000–10,000 sq ft) or a Meenar at ₹38,500 (12,000–18,000 sq ft) for a whole estate floor.
3. A small monthly refill. From ₹999 per zone — the only recurring cost.
4. A signature scent. A Hotel Collection blend from ₹299, chosen once.
5. Reeds as a cheap base. An occasional reed top-up for the intimate corners.
And a portion of every order supports girl-child education through Nanhi Kali.
Two costs, never one
The reason home fragrance feels expensive to some people and trivial to others is that they are counting differently. The frightened number treats every rupee as recurring; the honest number separates the machine you buy once from the scent you top up. Get that distinction right and a luxury living room turns out to cost far less to run than its owner expects — because the big figure is a one-time capital cost, and the ongoing figure is small.
The upfront outlay, by home
What you spend once depends entirely on how you scent — zone by zone with individual machines, or the whole floor through the ducting. Both are legitimate; the choice is about the size of the property and how much you want to manage.
| Approach | System | One-time price |
|---|---|---|
| One living zone | Vaayu | ₹11,999 |
| Two or three zones | A Vaayu per zone | ₹23,998–₹35,997 |
| Whole floor, 8,000–10,000 sq ft | Aangan HVAC | ₹25,999 |
| Whole estate, 12,000–18,000 sq ft | Meenar HVAC | ₹38,500 |
Notice that once a home has three or more zones, the whole-floor Aangan at ₹25,999 starts to rival buying three separate Vaayu units — and gives you one even signature and one thing to maintain instead of three. That crossover is the main reason large penthouses tend to go HVAC.
The running cost, honestly
Once the machine is in, the whole ongoing bill is refills and the occasional new scent. On a timed, medium schedule, budget roughly one 100ml refill (₹999) per active zone per month — so about ₹999 for a one-zone room, ₹2,000–₹4,000 for a busy multi-zone villa. A signature scent from ₹299 is chosen occasionally, not monthly. That is genuinely the entire recurring cost; there is nothing else to feed. For the detailed month-by-month consumption maths, see the companion piece on how much fragrance a large villa needs every month.

Versus candles and sprays
The comparison that reframes everything is with the luxury candle. A fine scented candle is a beautiful object, and I am not against them — but as a way to fill a large room they are ruinous. A candle burns itself away in an evening or two and cannot reach across a great room in the first place; keeping a villa scented that way means burning several at once, repeatedly, forever. A room spray is worse value still: it flashes and fades within minutes. A diffuser sips a ₹999 refill over weeks and actually projects. So the honest verdict is that the machine route, which looks more expensive on day one, is dramatically cheaper over any real span of time — and it is the only one that fills the room at all. Keep a candle for its flicker on the coffee table; let the Vaayu do the scenting.

Versailles
When a client baulks at ₹11,999, I ask what they were spending on candles. The answer, added up over a year, is almost always more — and the candles never filled the room anyway. The machine only looks like the expensive choice.
I would rather you bought one good system once and fed it a modest refill each month than kept pouring money into things that burn away by bedtime. That is not the luxurious way to think about it; it is simply the honest one.
Buy well once, run it lightly, and a great room smells considered for years. Your home gets a signature; a girl gets a classroom through Nanhi Kali.

Facts verified August 2026: The cost of scenting a large home separates into a one-time machine cost and a small recurring refill cost; over any real span, a nebulising diffuser is cheaper than filling a room with candles or sprays and is the only method that projects across a large volume. The effect of ambient scent on how a room feels is real but moderate, and no fragrance improves an unclean or poorly ventilated room.
