Founder Diaries · Hotel-at-Home Fragrance
How many bottles should I keep? Two open at a time - one scent per room. A pair of 100ml bottles typically lasts a 2BHK a few months of everyday diffusing.
What drives usage up or down? Dose and hours. Six drops on continuous mist for eight hours uses more than three drops on intermittent. Heavier hosting months use a little more.
Hotel Collection scentsFrom ₹299 The thing that surprises new diffuser owners is how little fragrance a room needs - just 3-6 drops in a full tank, or roughly 5-10 drops per 100ml of water. A 100ml Hotel Collection bottle holds hundreds of those drops, so one bottle runs a single diffuser for months of daily use. Scale that to a 2BHK's two diffusers and you are still measuring monthly consumption in fractions of a bottle, not bottles. Home fragrance is a genuinely cheap daily habit.
Sukoon · the diffuser₹1,799 Two levers decide your rate: how many drops per fill and how many hours you run. A living-room Sukoon at 6 drops on continuous mist for a whole evening uses roughly twice what a bedroom Boond at 3 drops on intermittent does. Neither is much, but if you want to stretch bottles, lean on intermittent mode and the lower end of the dose range - the room reads as expensive when the scent is faint anyway.
Boond · small room₹799 For a 2BHK, keep two bottles going - one scent per room. A pair of 100ml (₹999) bottles typically lasts a few months of everyday diffusing across both diffusers. When one runs low, reorder it as a refill or step up to a 300ml (₹1,799) for the scent you use most - it is the best value per ml. Two open bottles is the natural stock level for a two-room home.

Facts verified August 2026: An ultrasonic diffuser disperses a water-based fragrance as a cool micro-mist, scenting a room without heat or flame and adding a little humidity. Great hotels use commercial HVAC scenting to create a signature smell; at home the same effect comes from a diffuser plus a hotel-inspired blend. SOSA Sukoon is a 500ml ultrasonic cool-mist diffuser with a 7-colour mood light (₹1,799); Boond is a 300ml mini ultrasonic diffuser (₹799); both run the water-based Hotel Collection fragrance. The Hotel Collection comes in seven scents (Ritz-Carlton, Westin, 1 Hotels, St. Regis, Shangri-La, Four Seasons and W Hotels styles) in 15ml (₹299), 100ml (₹999) and 300ml (₹1,799), plus 15ml Pack of 7 (₹1,799); dose 3-6 drops per tank, use SOSA diffuser fragrance only (not raw essential/carrier oils), and rinse between scents. For large, open-plan or high-humidity spaces the waterless SOSA Vaayu (₹11,999, up to 1000m³) adds no humidity; the Aangan (₹25,999) is a whole-home HVAC system. The scents are SOSA's own interpretations; SOSA is independent and not affiliated with any hotel brand. Prices and availability are subject to change - see the live product pages.
Two diffusers use surprisingly little: at a few drops per fill, a 2BHK gets through roughly one to two 100ml bottles across a few months, not per month. Home fragrance is one of the cheapest luxuries you can run daily.
Quick answers — read this first
How much fragrance per month for a 2BHK? Very little - two rooms on daily use share about one 100ml (₹999) bottle every two to three months, so under half a bottle a month between both diffusers.How many bottles should I keep? Two open at a time - one scent per room. A pair of 100ml bottles typically lasts a 2BHK a few months of everyday diffusing.
What drives usage up or down? Dose and hours. Six drops on continuous mist for eight hours uses more than three drops on intermittent. Heavier hosting months use a little more.
The short answer
Short answer: A 2BHK running two diffusers on daily use gets through roughly one to two 100ml (₹999) Hotel Collection bottles across a few months - well under a bottle a month between both rooms - depending on dose and runtime.
The pick: the SOSA Sukoon (₹1,799) ultrasonic diffuser plus a Hotel Collection scent (from ₹299) is the hotel-at-home starter; a Boond (₹799) suits a small room or desk, and for a large, open-plan or high-humidity space the waterless Vaayu (₹11,999) adds no moisture.

Straight answer
How much ultrasonic fragrance does a 2BHK need every month?
1. Count your fills, not your rooms. Usage is drops per fill times fills per day. Two rooms filled once daily at 4 drops each is only 8 drops a day.
2. Estimate per bottle. A 100ml (₹999) Hotel Collection bottle holds hundreds of drops - months of use for one diffuser at a few drops a day.
3. Double it for two diffusers. Two rooms share roughly one to two 100ml bottles across a few months - budget under half a bottle a month total.
4. Adjust for dose and hours. Continuous mist and six-drop doses burn faster than intermittent, three-drop ones. Restraint stretches every bottle.
5. Buy two scents, refill the favourites. Keep one bottle per room open; reorder the ones you reach for as refills (from ₹999).

Keep two open, refill the loved ones
Boond · small room₹799 For a 2BHK, keep two bottles going - one scent per room. A pair of 100ml (₹999) bottles typically lasts a few months of everyday diffusing across both diffusers. When one runs low, reorder it as a refill or step up to a 300ml (₹1,799) for the scent you use most - it is the best value per ml. Two open bottles is the natural stock level for a two-room home.
Tip: 300ml for your everyday scent, 100ml for the occasional one.
The hero of this guide SOSA Sukoon · 500ml Ultrasonic ₹1,799 A 500ml cool-mist ultrasonic diffuser with a 7-colour mood light and quiet, long runtime - the natural home for the Hotel Collection scents. Add a few drops to the water, choose continuous or intermittent mist, and one fill carries a room all evening. It gently humidifies too, which Indian air-conditioned rooms quietly love.

Your 2BHK monthly fragrance estimate
Even at heavy use, a 2BHK measures its fragrance in bottles-per-few-months, not per month - these are honest ranges.
Usage estimate
Roughly how long fragrance lasts in a 2BHK
| Use pattern | Both rooms daily | One 100ml lasts |
|---|---|---|
| Light (3 drops, intermittent) | ~6 drops/day total | ~3-4 months per bottle |

| Heavy (6 drops, continuous) | ~12 drops/day total | ~1.5-2 months per bottle |
| Two scents (one per room) | 1-2 x 100ml across a few months | Buy two, refill favourites |
| Everyday scent | Step up to 300ml (₹1,799) | Best value per ml |

The SOSA principle
People overestimate how much fragrance a home uses by an order of magnitude. Two rooms, run daily, cost a few rupees of scent a day.
The luxury is real; the running cost barely is.
Seven hotels, one diffuser Hotel Collection Fragrance From ₹299 Water-based, ultrasonic-safe scents, each SOSA's own interpretation of a famous hotel signature - Ritz-Carlton-style white tea & cedar, Westin-style spa white tea, St. Regis-style amber & violet, and more. Try any scent in a 15ml (₹299), size up to 100ml (₹999) or 300ml (₹1,799), or take all seven as the 15ml Pack of 7 (₹1,799). Shop the 7 scents →
You will replace a diffuser's water far more often than its fragrance. A 2BHK's monthly scent bill is smaller than a single nice candle.

The 7 Hotel Collection scents
The whole point of the Sukoon is the scent you run through it. The Hotel Collection is seven of SOSA's own interpretations of the signatures great hotels are known for - pick by the room and the mood you want, try a 15ml first, then size up to the one you love. A portion of every order supports girl-child education through Nanhi Kali.
The Hotel Collection · 7 scents in your Sukoon
Which hotel signature for which room and mood
| Scent (inspired by) | Notes | Best for |
|---|---|---|
| Quiet Luxury · Ritz-Carlton style | White tea, bergamot, cedar | Living room & lobby-calm; understated and expensive |
| White Tea Serenity · Westin style | White tea, aloe, cedar | Bedrooms; spa-clean, weightless, restful |
| Forest Suite · 1 Hotels style | Cedarwood, vetiver, green leaves | Home office & study; fresh, focused, woody |
| Old-World Glamour · St. Regis style | Amber, violet, woods | Master bedroom, evenings; plush and romantic |
| Tea Garden · Shangri-La style | Jasmine, green tea, white tea | Guest rooms; serene, Asian-spa calm |
| Warm Welcome · Four Seasons style | Citrus, floral, sandalwood | Entryway & whole home; gracious, five-star |
| Lobby Bar · W Hotels style | Citrus, pepper, amber | Dining & entertaining; bold, after-dark energy |
Sizes & how to use: every scent comes as 15ml (₹299, to try), 100ml (₹999, the value bottle) or 300ml (₹1,799, best per-ml); the 15ml Pack of 7 (₹1,799) is the whole wardrobe. Add just 3-6 drops to the Sukoon's water tank and adjust to taste - a little goes a long way - and rinse the tank when you switch scents so each stays true. These are water-based, ultrasonic-safe fragrances made for SOSA diffusers; do not substitute raw essential or carrier oils, which can clog the misting plate. The scents are SOSA's own interpretations inspired by (not affiliated with) the named hotels. A portion of every order supports girl-child education through Nanhi Kali.
When the room is big or open-plan SOSA Vaayu · Waterless Cold-Air ₹11,999 The Sukoon is perfect for a bedroom or a normal living room; for a large, open-plan or high-ceilinged space - or if you want zero added humidity in already-humid coastal air - step up to the waterless Vaayu (up to 1000m³, app + timers). For a whole home, the ducted Aangan (₹25,999) carries one signature through every room. Compare Sukoon vs Vaayu →

Frequently asked questions
So how many bottles a month does a 2BHK really use?
Less than one. Two diffusers on daily use share about one 100ml (₹999) bottle every two to three months, so under half a bottle a month total. If you run two different scents, budget one to two 100ml bottles across a few months.
Should I buy 100ml or 300ml bottles for a 2BHK?
Buy 100ml (₹999) to try a scent across a room; step your everyday favourite up to 300ml (₹1,799) for the best value per ml. Most 2BHKs settle on one 300ml workhorse and a 100ml for variety.
Does running two diffusers double my fragrance cost?
In drops, yes - two rooms use roughly twice one room - but the total is still tiny: a few rupees of scent a day for the whole flat. The bigger recurring cost is simply topping up the water.
How can I make my bottles last longer?
Dose at the low end (3 drops), favour intermittent over continuous mist, and time each diffuser to when you use the room rather than running it all day. Restraint stretches bottles and, conveniently, smells more expensive.
Is it cheaper than candles?
Considerably. A 100ml bottle at a few drops per fill outlasts many candles and costs less over its life, with no wax to burn down, no flame, and the freedom to change scent whenever you like. It is the most affordable daily luxury I know.
Cheaper than you think
Two rooms, daily, for a few rupees of scent a day
Keep two Hotel Collection bottles open - one per room - and refill the favourites. A 2BHK's monthly fragrance bill is smaller than one candle.
