Pro-300 is designed for large bedrooms, living rooms, offices, spa rooms and studios where you want a stronger scent presence than a compact personal diffuser.
Choosing a diffuser for a large room? Compare JC002 and A-311 V2
Start with JC002 if flexible placement and direct buttons matter most. Compare A-311 V2 if you prefer a visible digital display and touch controls. PRO300 remains available on this page.
For living rooms and open home areas where you want simple on-device control and a choice of installation styles.
For home, office and studio spaces where you want to see and adjust the scent routine directly on the diffuser.
Both models are rated for up to 2,000 sq ft. Actual results depend on room layout, airflow, oil and settings; coverage is not a guarantee for every room. Bluetooth is optional; neither model supports Wi-Fi.
Keep the 300mL model shown on this page. A larger oil reservoir does not, by itself, mean stronger output or wider coverage.
