Standard Evaporation Expectations
A high-quality 100ml alcohol-free reed diffuser lasts between 75 and 90 days under standard room conditions. A 200ml grand diffuser lasts approximately 4 to 6 months.
However, environmental factors in your home can either accelerate or extend this lifespan:
- Room Airflow: High-draft areas near AC vents evaporate liquid faster.
- Stick Count: Using all 8 reeds creates stronger throw but consumes oil faster. For small rooms, use 5 sticks to prolong life.
- Sunlight: Keep bottles out of direct sun, which heats the oil and causes rapid evaporation.
