"I stopped rebuying little bottles. One 500ml Garden Bloom refill has kept my living room diffuser going for over a year. Same rose-and-jasmine scent, a fraction of the cost."

The short answer
Short answer: a spray is a burst; a reed refill scents continuously for months.
The pick: a reed refill as your always-on base, from ₹2,399.
Use a spray: only for an instant, targeted refresh.
Straight answer
A burst vs an always-on source
A room spray and a reed diffuser refill do different jobs. A spray is a burst - a cloud of scented droplets that smells strong for a few minutes and then fades, because there is nothing left releasing fragrance. It is useful for an instant refresh. A reed diffuser refill is the opposite: the reeds release scent slowly and continuously, so a room stays evenly fresh for months on one fill - no propellant, no sharp top note, and a fraction of the cost per day. The smart setup is both: a reed refill as the always-on base that keeps the room gently scented, and a spray kept for a quick, targeted lift before guests. But if you are choosing one, the reed refill is the one that actually keeps a home smelling good. From ₹2,399.
One line: a spray is a burst that fades in minutes; a reed refill scents continuously for months - the reed refill is the base, the spray a top-up.
