Why does that question matter here? Because homes here are lived in with doors open, and a machine's advantage is holding a bounded volume at one even strength.
When should they start using it? A few weeks after moving in. A wet spell keeps windows shut on a house still giving off paint and polish, so the airing takes longer here.
One extra question in this city
For a large villa the standard reasoning is short. Is the home big enough - a villa usually is, and the SOSA Vaayu at eleven thousand nine hundred and ninety-nine rupees is rated for up to a thousand cubic metres, stated as about two thousand to three thousand square feet. Is it connected - a villa's ground floor usually runs from the entrance through living and dining to a garden door, with a staircase in the middle, which is precisely the case for a machine because a bottle in one corner of that space produces a pocket and leaves the rest untouched. On those two questions the answer is the machine, and in most cities that would be the end of it. Here there is a third question and it is worth asking before spending, because it decides how much of what you are buying will actually be used. Because this city's weather allows it, villas are lived in open: sliding doors to a garden or a deck, often both ends of the living space open for cross ventilation, and that arrangement frequently holds from morning until dusk. Air passing through a house at that rate is why these houses feel fresh with no help at all, and it is also why a machine running at midday into an open living room is scenting the garden. A nebuliser does not project fragrance; it releases a dry nano-mist and relies on the air the building is moving to distribute it, and an open house does not circulate air so much as replace it. So the honest question is: how many hours a day is the house actually shut? Most households do close up at dusk - insects, the family moving indoors, air conditioning in the bedrooms - and from that point the villa behaves like the bounded volume the rating describes. If the closed period is a good part of the evening and night, the machine earns its place, because the evening is exactly when it matters: the family is indoors together, guests arrive, and the house is experienced as a whole rather than as a route to the garden. A four-hour window from dusk at moderate intensity, set from the Bluetooth app or the buttons on the unit, is how most owners here end up using it, and the one, four, eight and twenty-four hour windows with day selection exist for precisely that. If the house is shut only for sleeping, bottles are the better buy at any square footage, and that is a real conclusion rather than a hedge. So, the recommendation. Where the villa is over roughly two thousand square feet of connected volume and closed for a meaningful part of the day: the Vaayu, with three pieces of advice attached. Place it on the closed side of the house and in the path of internal airflow - the foot of the staircase, the circulation between living space and hall, or near an air conditioning return - and not beside the garden door, where its output leaves. In a two-storey villa place it low, because warm air rises through a stairwell and will carry the mist to the landing, and judge the intensity from an upper landing rather than beside the unit, since the top of the house over-scents first. And start at the lowest useful setting. The rest of the specification is worth knowing: waterless, so no tank, no visible plume, no humidity added and no oily film, which matters in a city with long damp spells; four hundred millilitre tank lasting up to around seventy-five days a fill; under thirty-eight decibels; twelve volts at five watts; nine hundred grams; black or white; freestanding on a shelf or wall and HVAC mountable; auto-stop and key lock; CE, RoHS and SGS; made in India; and four one hundred millilitre hotel-inspired oils included so it runs the evening it is switched on. Refills are the waterless nebuliser oils at one thousand and forty-nine rupees for a hundred grams or one thousand eight hundred and forty-nine for three hundred, and never the water-based Hotel Collection at two hundred and ninety-nine rupees, which is a separate system for ultrasonic diffusers - worth writing on the card so nobody tops it up wrongly. Where the villa is built as separate rooms, or stands open nearly all day, or the household would rather not have a device: reed diffusers, one per zone that matters rather than one for the house. Morning Freshness at seven hundred and forty-nine rupees for fifty millilitres and one thousand two hundred and forty-nine for one hundred and thirty is Malabar lemon with peppermint and eucalyptus, clean and cool and the best entrance choice. Mountain Breeze at eight hundred and forty-nine and one thousand three hundred and forty-nine is Himalayan pine, sage and cedar, dry and resinous, which reads well in a damp month and does not compete with jasmine coming in from a garden. Evening Calm at seven hundred and ninety-nine and one thousand two hundred and ninety-nine is lavender with chamomile for a bedroom. Garden Bloom at the same is British rose with night-blooming jasmine, best in an interior room. Fresh Brew at eight hundred and forty-nine and one thousand three hundred and forty-nine is Coorg coffee with Kerala vanilla. A duo set at one thousand four hundred and ninety-eight to two thousand five hundred and ninety-eight rupees is the version to hand over at a housewarming. One local placement rule: keep bottles in the calm interior of each room, away from open windows, garden doors and fan airflow, because a bottle in moving air reads strong at the sticks and of nothing two metres away, and empties sooner. Two closing notes specific to a new villa here. Whatever you give, say it should start in a few weeks rather than on day one: paint, polish, varnish, adhesive and new plywood release solvent for days to weeks, and in this city a wet spell keeps the windows shut on a house that is still curing, which stretches that period beyond the textbook few weeks. Ventilation whenever the weather allows, fans moving air through rooms rather than around them, cupboard doors left open because new plywood off-gasses inside them, and patience. And bedrooms behind closed doors sit outside a machine's field, so a bottle belongs in the main bedroom regardless. Fragrance is a finishing touch and never a fix.
How many hours a day do the garden doors stay open?
Two usual questions, one local one.

Versailles
The Vaayu is the most expensive thing we make and we turn down more orders for it than for anything else in the range. Not because we do not want to sell it - because most homes do not need it. It covers up to a thousand cubic metres, roughly two to three thousand square feet, and that is a villa, a penthouse, a large open-plan flat or a house with a double-height room. An ordinary 2BHK is not that, and in an ordinary 2BHK a reed diffuser at seven hundred and forty-nine rupees does the job better than eleven thousand nine hundred and ninety-nine rupees of machine would. So the question we ask is never what somebody spent on their house. It is how many cubic metres of air are in it.
The second thing we say, and almost nobody expects it, is wait a few weeks. A brand-new home smells of paint, varnish, polish, cement and new wood, and those are not smells to cover - they need open windows and time, and they go on their own. Give the machine at the housewarming by all means, but tell them the scenting starts once the building has finished smelling of being built. It is the same rule we apply to a new car, for the same reason: adding fragrance to a smell that is fading anyway is how a good product gets blamed for a bad result.
Two honest limits. Reed diffusers do not fail in large homes, they simply do not reach - a diffuser on a console table scents the area around that console table, which is not a fault, it is physics, and several of them is a real alternative to one machine. And there are two machines above the Vaayu, the Angaan and the Meenar, which are HVAC units for showrooms and hotel floors rather than houses - so if a home is genuinely far beyond three thousand square feet, message us rather than assuming more money solves it.
