Straight answer
For home use, choose real, gentle and room-right
A refill for a home you live in all day has to clear a slightly higher bar than a one-off scent: it should be real, gentle and right for the room. Real because you will smell it constantly, and a real, layered material wears far better over hours than a thin synthetic. Gentle because it is in the air you and your family breathe - SOSA refills are phthalate-free, paraben-free, IFRA-compliant and low-VOC, on a coconut-derived (CCT) base, so they suit everyday, all-day use (kept away from children and pets, and never burned). And room-right because the best home is scented in zones: Garden Bloom in living areas, Evening Calm in bedrooms, Morning Freshness in bathrooms and kitchens, Mountain Breeze in a study, Fresh Brew in a cosy corner. On size, a 300ml keeps one room going for 8-11 months, while a 500ml suits a larger or open-plan space, or committing to a signature home scent, for 14-18 months at the best value. SOSA refills start at ₹2,399.
