Should a living room scent be fresh or warm? It depends on the time of day - fresh and bright for daytime and gatherings, warmer for cosy evenings. The living room is versatile, so many people keep two scents.
Where should I place the diffuser in a living room? Central and a little off to the side, away from strong airflow, so the scent spreads evenly through the room.

Straight answer
The best diffuser fragrances for a bright, uplifting living room
The living room is your most sociable space, so it suits bright, open, uplifting scent by day. Lobby Bar (citrus, pepper and amber) is the liveliest; White Tea Serenity (white tea and aloe) keeps it clean and fresh; Warm Welcome (citrus and sandalwood) bridges into cosy evenings. All are water-based ultrasonic diffuser fragrances. Because the living room does so many jobs, many people keep two scents - a fresh one for daytime and gatherings, a warmer one for winding down at night. Place the diffuser centrally, away from strong airflow, and run a few drops so the whole room feels alive without anyone thinking about why. From ₹299, composed in India by an ISIPCA-trained perfumer.
One line: bright by day, warm by night - Lobby Bar or White Tea Serenity, then Warm Welcome.
A lovely place to start is Lobby Bar - citrus, pepper and amber, from ₹299. Add a few drops to your diffuser and the room shifts.

What actually sets the mood
A living room does many jobs, so its scent has to be versatile. Three things help.
1
Bright and open
Sociable rooms like fresh air
A living room should feel open and alive, especially by day. Citrus and clean white tea keep the air bright and sociable - the feeling of a room with the windows open, ready for people.
Tip: place the diffuser centrally and away from fans or open windows so the scent spreads evenly.
2
Two scents, two moods
Fresh by day, warm by night
The living room shifts from daytime bright to evening cosy, so it is the one room worth keeping two scents for - a fresh one for gatherings and a warmer one for winding down. Rinse the tank when you switch between them.
3
Water-based, diffuser-safe
A fragrance made for mist, not reeds
A sociable room should stay clean, with no oily film - SOSA's Hotel Collection is water-based - you add a few drops to your diffuser's water tank and it mists cleanly, without the greasy film or clogging you get from thick oils. This is not reed diffuser oil, and it is not a neat essential oil; it is a fragrance built for an ultrasonic diffuser. From ₹299.
Tip: start with 3 to 6 drops per fill and build up - a little goes a long way.
The SOSA principle
The living room is the most sociable room in the house - its air should feel that way.
Bright, open scent keeps a shared room feeling alive and ready for people. Switch to something warmer at night and the same room becomes the place everyone wants to stay.
Which scent, and how to use it
For an uplifting living room, Lobby Bar is the liveliest and White Tea Serenity the cleanest by day, with Warm Welcome bridging into cosy evenings.

A note from Sonal
The living room is where everyone ends up, so I keep its air bright and open by day and switch to something warmer once the evening settles in.
So I composed the Hotel Collection - seven water-based diffuser fragrances, each our own interpretation of the signature scent a great hotel is known for. They are made to run cleanly through an ultrasonic diffuser, not to sit in reeds. This is not reed diffuser oil; it is a water-based fragrance you add a few drops of to the tank.
One honest note: fragrance sets the mood, it does not fix a stuffy or damp room - open a window and clear the air first, then let the scent do the quiet, expensive work. A little goes a long way, so start with a few drops and build up to taste.
