What does that cost? Working from a 100ml bottle, roughly ₹150-250 of fragrance a month - a few rupees a day for a home that smells like a hotel.
What if I run two diffusers? A Sukoon plus a Boond roughly doubles it to ~30-45ml a month - still comfortably covered by one 100ml bottle every couple of months, or a 300ml (₹1,799) for the best per-ml value.
Hotel Collection scentsFrom ₹299 The single biggest factor is dose. A full Sukoon tank wants just 3-6 drops - roughly 0.5-0.9ml - of Hotel Collection fragrance. That restraint is not stinginess; it is what makes the scent read as luxurious rather than heavy. Because the dose is small, your monthly consumption stays low even with daily use. Over-dosing wastes fragrance without improving the result.
Sukoon · the diffuser₹1,799 Run the Sukoon one tank a day and you refill roughly daily; run it only in the evenings and a tank may last two days. A single-diffuser 1BHK typically lands around 15-25ml a month. Using intermittent mist (say 10s on, 10s off) stretches each fill across more hours, so you refill less often and a bottle lasts longer for the same daily coverage.
Boond · small room₹799 Add a Boond in the bedroom and you are dosing two tanks, so monthly usage rises to roughly 30-45ml. That is still modest - one 100ml bottle every couple of months, or a single 300ml (₹1,799) that lasts a two-diffuser 1BHK the better part of a year. Even the fullest 1BHK setup is a few hundred rupees of fragrance a month.

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.
Far less than people expect. At 3-6 drops a fill, a 1BHK household runs through roughly 15-25ml of fragrance a month - which is why one 100ml bottle lasts a small home four to six months and a season of scent costs a few hundred rupees.
Quick answers — read this first
Roughly how much per month? About 15-25ml for a typical 1BHK running one Sukoon daily - so a 100ml Hotel Collection bottle (₹999) lasts around four to six months.What does that cost?

The short answer
Short answer: A 1BHK household running one diffuser daily uses roughly 15-25ml of ultrasonic fragrance a month, so a 100ml Hotel Collection bottle (₹999) lasts about four to six months; two diffusers use around 30-45ml a month.
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 1BHK household use per month?
1. Count your fills. One Sukoon tank run daily is roughly one fill a day; at 3-6 drops (about 0.5-0.9ml) each, that is a small amount.
2. Do the monthly math. One fill a day at ~0.5-0.9ml works out to roughly 15-25ml a month for a single-diffuser 1BHK.
3. Pick the bottle to match. A 100ml Hotel Collection bottle (₹999) covers about four to six months of that; a 300ml (₹1,799) is the best per-ml value if you know your scent.
4. Add a bit for a second unit. A Boond in the bedroom roughly doubles usage to ~30-45ml a month.
5. Dose lightly to stretch it. Staying near 3 drops rather than 6, and using intermittent mode, meaningfully extends how long a bottle lasts.

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.

Frequently asked questions
How long does a 100ml bottle last in a 1BHK?
Running one Sukoon daily at 3-6 drops a fill, a 100ml Hotel Collection bottle (₹999) lasts a 1BHK household roughly four to six months. Evenings-only use stretches it further; a second diffuser shortens it.
What does a month of scent actually cost?
Working from a 100ml bottle at typical 1BHK usage, roughly ₹150-250 a month - a few rupees a day. It is one of the lowest-running-cost ways to make a home feel expensive.
Should I buy 15ml, 100ml or 300ml for a 1BHK?
Start with a 15ml (₹299) or the Pack of 7 to find your scent. Once you know it, a 100ml (₹999) is the value bottle for a single-diffuser 1BHK; a 300ml (₹1,799) gives the best per-ml cost for a two-diffuser home.
Does using more drops make it last less?
Yes, proportionally. Six drops a fill uses roughly twice what three does. Since your nose habituates to your own home, most people over-dose without benefit - staying near 3 drops keeps the scent lovely and the bottle lasting.
How much does a second diffuser add to my usage?
Adding a Boond roughly doubles monthly usage to ~30-45ml, since you are dosing two tanks. It is still modest - one 100ml bottle every couple of months, or a single 300ml for most of a year.
