What schedule should a home diffuser run on? For most homes, a morning block and an evening block totalling about eight to ten hours, rather than continuous overnight running. Start the evening block about 45 minutes before people are usually home so the fragrance has settled rather than arriving as a burst. The SOSA Vaayu (₹11,999) has 1h/4h/8h/24h timers with adjustable intensity through its Bluetooth app.
How much does a SOSA Vaayu cost to run per year? The machine is ₹11,999 once. It draws 5W, roughly 1.5 units of electricity a month on a ten-hour daily schedule, and the 400ml tank lasts up to about 75 days depending on intensity and run hours, so most homes refill around five times a year. There is no water, no wax and no consumable other than the fragrance oil.

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, DC 12V/1A at 5W, a body of 165 x 80.5 x 215mm weighing 0.9kg, freestanding, wall or HVAC mounting, auto-stop and key-lock, and CE, RoHS and SGS certification. 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.

Quick answers — read this first
How do I set up a SOSA Vaayu in a home? Air and clean the home first, then mount the machine on the air path - a passage wall above the eyeline, beside the air-conditioning return, inside a ventilated cabinet or on ducted HVAC. Fill the 400ml tank with one restrained fragrance oil, set two timer blocks rather than running all night, and start at the lowest intensity for a fortnight before adjusting. The Vaayu is ₹11,999 and covers up to 1000m³, about 2,000-3,000 sq ft.What schedule should a home diffuser run on?

The short answer
Short answer: air and clean first, mount it on the air path rather than in a corner, fill the 400ml tank with one dry restrained oil, set a morning and evening timer block totalling eight to ten hours, and start at the lowest intensity for two weeks. That is the whole setup for a SOSA Vaayu (₹11,999) across about 2,000-3,000 sq ft.
The pick: the SOSA Vaayu (₹11,999) wall mounted above the eyeline on a corridor or beside the air-conditioning return, running low on two daily timer blocks.

What fits your home
Straight answer
How do I set up and run a SOSA Vaayu in a quiet luxury home?
Five steps. One, get the base right. Air the home daily, clean the bins, drains, fridge and laundry basket, dry towels properly and open wardrobes occasionally. Fragrance is the last five per cent, and scent over a stale base gives you both smells. Two, place it on the air path. The best position in most Indian flats is wall mounted in a passage above the eyeline, because corridors connect rooms and carry air; next is beside the air-conditioning return, then inside a ventilated cabinet with genuine airflow, then HVAC mounted in ducted homes. Freestanding on a low shelf works but leaves an object in the room. Avoid the far corner of a living room, which looks neat and performs badly. Three, fill it. The Vaayu takes pure fragrance oil in its own 400ml tank - it is not an ultrasonic diffuser and does not take water or a water-based blend. Choose one dry, restrained profile for the whole floor: clean woods, tea, linen, mineral or green rather than gourmand or heavy amber. Four, set the schedule. Two blocks work better than continuous running for most households: a morning block while people get ready, and an evening block starting about 45 minutes before anyone is usually home, so the fragrance has settled rather than arriving as a burst. Eight to ten hours a day total is plenty. The app offers 1h, 4h, 8h and 24h timers with adjustable intensity. Five, set the intensity low and leave it. Start at the lowest usable setting and do not change it for a fortnight, because you acclimatise to your own home within days and will otherwise keep raising it until visitors are being polite. On the numbers: the machine is ₹11,999, covers 1000m³ (about 2,000-3,000 sq ft), runs under 38dB and draws 5W, which is roughly 1.5 units of electricity a month on a ten-hour daily schedule. A tank lasts up to about 75 days, so most homes refill around five times a year, and refilling takes two minutes with no water or residue to clean. It has auto-stop and a key-lock so settings are not changed by accident. Honest boundary: it is a fragrance device, not an air purifier, and it cannot cover cooking, damp, a musty wardrobe or fresh paint.
Clean first, mount on the air path, one oil in the 400ml tank, two timer blocks totalling eight to ten hours, lowest intensity for a fortnight.

Placement, schedule and intensity - the complete setup
Placement, schedule and intensity are the three settings that decide whether this works. Everything else is detail.
1
Placement
Air path first, eyeline second, corners never
Scent travels with moving air, so the machine belongs where air already moves. In a typical flat that is the corridor connecting the bedrooms to the living area, or the wall near the air-conditioning return. Mount it above the eyeline and it disappears. In a ducted home, HVAC mounting is the cleanest option of all. Inside a cabinet works only if air genuinely circulates - a vented shoe cabinet or an open-backed console, not a sealed cupboard. The far corner of the living room is the classic mistake: tidy, invisible, and patchy in performance.
Tip: if the fragrance is uneven, move the machine before you raise the intensity.
Freestanding, wall mount or HVAC mount, at 0.9kg, so almost every home has an invisible option.

2
Schedule
Two blocks, eight to ten hours, 45 minutes ahead of arrival
Continuous running around the clock is rarely needed in a home and uses more oil than it is worth. A morning block while the household is getting ready and an evening block beginning about 45 minutes before people usually come home covers most patterns, with the fragrance settled rather than arriving as a spike. If someone in the house is a light sleeper or sensitive to fragrance, stop it entirely overnight. Set it once in the app and leave it, because a schedule that survives your busy weeks is the entire point.
1h, 4h, 8h and 24h timers with adjustable intensity over Bluetooth, plus onboard buttons if you prefer.

3
Intensity and refills
Lowest usable setting, then leave it alone for two weeks
The most common error is running too high in week one. Start at the lowest setting, live with it for a fortnight and use guests as your instrument: if someone asks what the scent is, it is too high; if someone says the house feels good, it is right. On refills, the 400ml tank lasts up to about 75 days depending on intensity and hours, so plan on roughly five fills a year. Refilling takes a couple of minutes, and because there is no water there is nothing to wash out or dry between fills.
Tip: raise the intensity only after a fortnight, and only by one step.
400ml of pure fragrance oil, up to about 75 days per fill, with no water, wax or residue to deal with.

The SOSA principle
A good scenting setup is one you stop interacting with. If you are adjusting it every week, the placement or the level is wrong, not the fragrance.
Set it up properly once and the next decision is a refill in two months.
Settings by home type, and the running cost
Settings vary a little by home type. These four cases cover most Indian households, and the differences are about air movement rather than floor area alone.
The SOSA plan
Settings by home type
| Your home | How to run it |
|---|---|
|
A 2BHK or 3BHK flat on one floor, doors mostly open
|
One machine on the corridor wall. Two blocks totalling eight to ten hours at the lowest intensity. View → |
|
An open-plan flat with the kitchen in the same air
|
Same machine, positioned away from the hob and near the AC return. Run continuously at low rather than in bursts, and ventilate while cooking. View → |
|
A home with ducted air-conditioning throughout
|
HVAC mount and let the existing airflow distribute it. Match the schedule to when the system actually runs. |
|
A duplex or two floors with a closed staircase
|
Air does not cross a closed stair reliably. Treat each floor separately and ask us before assuming one machine covers both. |
On the fragrance itself, keep it dry and restrained: clean woods, tea, linen, mineral and green characters hold up in Indian conditions where sweet and heavily ambered profiles turn cloying by the afternoon. Choose one oil for the whole floor and vary intensity rather than scent between zones. The room-by-room reasoning is in the best fragrances for a quiet luxury home, and if you are still deciding whether the machine belongs in your interior at all, we answer that honestly in is the SOSA Vaayu suitable for a quiet luxury home. The pillar for this cluster is how to make your home feel more expensive.
One afternoon of setup, then two months of nothing
SOSA Vaayu ₹11,999 - 1000m³, 400ml for up to 75 days, 1h/4h/8h/24h timers, under 38dB, 5W.
The best sign that a home scenting setup is right is that you forget the machine exists and only remember it when the tank runs low.

Two final practical notes. First, if the scent feels uneven, move the machine before you raise the intensity - placement fixes far more problems than power does. Second, the honest boundary that governs every page we write: fragrance works alongside ventilation and cleaning and never instead of them. It cannot cover cooking, damp, a musty wardrobe, pet odour or new-paint off-gassing, and it makes no air-purification or health claim. Our hotel-inspired fragrances are SOSA's own interpretations and we are independent, not affiliated with any hotel. If you would like a schedule written for your actual routine, ask us what fits your home.

A note from Sonal
The setups that work are boring. A machine on a corridor wall, one oil, two timer blocks, the lowest intensity, and a refill every couple of months. The setups that fail are the ones people keep adjusting - moving it around, changing the fragrance, turning it up because they can no longer smell it in their own home.
So my advice is to do the placement carefully and then stop interfering. Mount the Vaayu where air already moves, fill the 400ml tank with one restrained oil, set the timers once, and choose the lowest setting you can live with. It covers 1000m³, runs under 38dB at 5W, and holds a fill for up to about 75 days. If the scent is patchy, move the machine rather than raising the intensity.
And the honest part I put on every page: fragrance sits on top of a home that is aired and cleaned first. It cannot cover cooking, damp, a musty wardrobe or fresh paint, and it is not an air purifier. Our hotel-inspired fragrances are our own original interpretations and SOSA is independent, not affiliated with any hotel. Made in India, and a portion of every order supports girl-child education through Nanhi Kali.
Frequently asked questions
Where should I mount the SOSA Vaayu in a home?
On the air path rather than in a corner. A passage wall above the eyeline is usually best because corridors connect rooms and carry air between them. Beside the air-conditioning return is the next best option, then inside a ventilated cabinet with genuine airflow, then HVAC mounting in ducted homes. If the scent is uneven, move the machine before raising the intensity.
What schedule should I run at home?
Two blocks totalling about eight to ten hours suits most households: one in the morning while people get ready, and one starting roughly 45 minutes before anyone is usually home so the fragrance has settled. The app offers 1, 4, 8 and 24 hour timers with adjustable intensity. If anyone in the house is a light sleeper, stop it overnight.
What intensity should I start at?
The lowest usable setting, held for a fortnight before you change anything. You stop noticing your own home's scent within days, so residents almost always run higher than visitors would choose. Use guests as the test: if someone asks what the fragrance is, turn it down; if someone says the house feels good, leave it alone.
How often will I refill it, and what goes in it?
Pure fragrance oil goes in its own 400ml tank, and a fill lasts up to about 75 days depending on intensity and daily hours, so roughly five refills a year. It is a waterless cold-air nebuliser, so it does not take water or a water-based blend, and there is nothing to wash out or dry between fills.
What does it cost to run, and is it safe to leave on?
The machine is Rs 11,999. It draws 5W, roughly 1.5 units of electricity a month on a ten-hour daily schedule. It has auto-stop and a key-lock so settings cannot be changed by accident, uses no water and no heat, and has no flame, which is why it can be left on a schedule and forgotten. It is CE, RoHS and SGS certified and made in India.
