How Long Does a Reed Diffuser Last?

A good reed diffuser should last months, not weeks. Scents of Glow reed diffusers last around 90 days of continuous, flame-free fragrance per bottle — most of a season from a single purchase, with no flame, smoke, or plugs.

What affects how long it lasts

• Number of reeds: more reeds means a stronger scent but faster use; fewer reeds last longer.
• Room conditions: heat, sunlight, and drafts make the oil evaporate faster — keep it out of direct sun and away from vents.
• Room size: a large, open room needs more reeds than a small bathroom.

How to make your reed diffuser last longer

• Use fewer reeds for everyday scenting, and add more only when you want a boost.
• Flip the reeds about once a week rather than daily.
• Keep it away from radiators, sunny windowsills, and air vents.

Reed diffuser vs. candle: which lasts longer?

A candle only scents your space while it's lit, and it shouldn't be left burning unattended. A reed diffuser works around the clock for about 90 days with no flame — so for everyday, continuous fragrance, a diffuser gives you far more scent per purchase.
